Why Turnover Growth Can Hide Falling Profit Margins

Introduction

Turnover is one of the first figures business owners use to describe growth.

“Sales are up 25%.”

“We have had our best month ever.”

“The business has crossed £1 million in revenue.”

These achievements can be meaningful. Higher turnover may show stronger demand, increased market share or successful expansion. However, turnover measures the value of sales before most business costs are deducted. It does not show how much of that income the business keeps.

A company can become busier, employ more people, serve more customers and generate record sales while producing less profit than before. In some cases, rapid turnover growth makes the problem harder to see because healthy bank receipts and constant activity create the impression that the business is performing well.

The underlying margin may tell a different story.

If a business earns £20 of profit from every £100 of sales and that falls to £8, it needs far more turnover merely to stand still. If growth also requires more stock, longer customer credit, additional staff or larger premises, the company can experience a cash squeeze at the same time as its sales increase.

The right question is therefore not only:

“How much did we sell?”

It is also:

“How much profit did we retain from each pound of turnover, and why did that change?”

This guide explains the figures behind that question and how business owners can respond.

What does turnover actually measure?

Turnover, often called revenue or sales, is broadly the income generated from the business’s ordinary trading activities before expenses are deducted.

For a retailer, this may be product sales. For a consultant, it may be fees billed for services. For a construction business, it may be revenue recognised from contracts. For a property manager, it should usually reflect the company’s own management fees and other earned income, not money collected and held for property owners.

Turnover is not the same as:

• cash received into the bank;
• gross profit;
• operating profit;
• taxable profit;
• the value of invoices raised without considering credits or revenue recognition;
• client money passing through the business;
• a director’s personal income; or
• the amount available for dividends.

For a VAT-registered business, reported turnover is normally shown excluding VAT. VAT collected from customers generally belongs to HMRC, subject to input tax recovery and the business’s VAT accounting method. Comparing a sales report that includes VAT with accounts that exclude it can produce a false growth figure.

The correct accounting treatment depends on the nature of the contracts and the applicable accounting standard. FRS 102 contains the revenue requirements used by many UK entities, while qualifying micro-entities may use FRS 105. Revenue should be recognised consistently and should reflect what the business has actually earned.

Turnover growth is not profit growth

Profit is what remains after relevant costs have been deducted. Different profit measures answer different questions.

Gross profit

Gross profit is turnover less direct costs or cost of sales.

Direct costs are the costs closely connected to delivering the product or service. Depending on the business, they may include:

• goods purchased for resale;
• raw materials;
• direct labour;
• subcontractors;
• production costs;
• packaging;
• delivery and fulfilment;
• platform commissions; and
• other costs that increase with sales.

The classification should be appropriate and consistent. Moving a cost between cost of sales and overheads changes the reported gross margin even though total profit stays the same.

Operating profit

Operating profit deducts the wider costs of running the business, such as administrative wages, premises, software, marketing, insurance and professional fees. It shows the result from normal operations before finance costs and tax, subject to the accounting presentation used.

Profit before tax

Profit before tax also reflects finance costs and other non-operating items before Corporation Tax or Income Tax is charged.

Net profit

“Net profit” can mean different things in different reports. It may refer to profit before tax, profit after tax or the final result after all costs. The business should define the measure used and apply it consistently.

For management purposes, gross profit margin, contribution margin and operating profit margin often give more useful early warnings than turnover alone.

What is a profit margin?

A profit margin expresses profit as a percentage of turnover.

Gross profit margin

Gross profit margin = gross profit divided by turnover x 100

If turnover is £100,000 and direct costs are £65,000, gross profit is £35,000. The gross profit margin is:

£35,000 divided by £100,000 x 100 = 35%

The business retains 35 pence from each £1 of sales to pay overheads, finance costs, tax and owners’ returns.

Operating profit margin

Operating profit margin = operating profit divided by turnover x 100

If the same business has operating costs of £25,000, operating profit is £10,000 and the operating margin is 10%.

Contribution margin

Contribution is sales less variable costs. It shows how much each sale contributes towards fixed costs and profit.

The distinction between gross profit and contribution depends on how costs are classified. A direct cost can be fixed, variable or partly variable. For example, a salaried production employee may be treated as a direct cost in gross profit but will not change immediately when sales volume changes.

Contribution analysis is particularly useful when assessing pricing, capacity, promotions and whether additional work is genuinely worthwhile.

A worked example: sales up, profit down

Consider a business comparing two financial years.

In the first year:

• turnover was £500,000;
• direct costs were £300,000;
• gross profit was £200,000;
• gross profit margin was 40%;
• overheads were £140,000; and
• operating profit was £60,000, giving a 12% operating margin.

In the second year:

• turnover increased to £650,000;
• direct costs increased to £422,500;
• gross profit increased to £227,500;
• gross profit margin fell to 35%;
• overheads increased to £187,500; and
• operating profit fell to £40,000, giving an operating margin of approximately 6.2%.

Turnover grew by 30%.

Gross profit increased by only 13.75%.

Operating profit fell by 33.3%.

The business processed £150,000 more sales but made £20,000 less operating profit. It also retained only 6.2 pence of operating profit from each £1 of turnover compared with 12 pence previously.

If the owner looked only at turnover, the year would appear successful. The margin analysis shows that the quality of the growth deteriorated significantly.

Why can turnover rise while margins fall?

There is rarely one cause. Margin erosion often results from several small changes occurring at the same time.

1. Prices have not kept pace with costs

Supplier prices, wages, utilities, insurance and software can increase while selling prices remain unchanged.

If the cost of delivering a £100 service rises from £60 to £68 and the selling price stays at £100, gross profit falls from £40 to £32. The gross margin falls from 40% to 32%.

The business may sell more units and report higher turnover, but it earns less from each unit.

Owners sometimes delay price increases because they fear losing customers. That concern may be valid, but holding prices indefinitely is also a decision. It transfers every cost increase into a lower margin.

Pricing should be reviewed using current delivery costs rather than historic assumptions.

2. Growth has been bought through discounts

Discounting can increase order volume while damaging contribution.

Suppose a product normally sells for £100 and has variable costs of £65. The normal contribution is £35.

A 10% discount reduces the selling price to £90. If the variable cost remains £65, contribution falls to £25.

The price fell by 10%, but contribution fell by approximately 28.6%.

The business now needs to sell 40% more units to produce the same total contribution:

£35 divided by £25 = 1.4

This is why apparently modest discounts can require a disproportionately large increase in volume.

Discounts may still be commercially sensible where they fill unused capacity, clear obsolete stock or secure valuable recurring work. They should be approved using contribution analysis rather than awarded automatically.

3. The sales mix has changed

Not every pound of turnover produces the same margin.

A business may sell:

• a premium service with a 60% gross margin;
• a standard service with a 35% margin; and
• a low-priced service with a 15% margin.

If growth comes mainly from the low-margin service, total turnover can rise while the overall gross margin falls.

The same issue arises across:

• products;
• customers;
• contracts;
• locations;
• sales channels;
• property units;
• staff teams; and
• project types.

An overall profit and loss account can hide this change. Segment-level reporting is needed to see which activity generated the growth.

4. Sales commissions and platform fees have increased

Higher sales may involve additional costs that are not obvious in the headline revenue figure.

Examples include:

• marketplace commission;
• card-processing charges;
• booking-platform fees;
• delivery charges;
• affiliate commission;
• sales-team bonuses;
• advertising cost per acquisition; and
• refunds and chargebacks.

If these costs are posted inconsistently or buried within overheads, the business may believe its core margin is stable when the cost of acquiring and processing each sale has increased.

Management accounts should show material channel costs in a way that allows the true contribution from each route to be compared.

5. Labour efficiency has deteriorated

A service business can grow turnover but lose margin if each job requires more staff time than expected.

Common causes include:

• underquoted work;
• scope creep;
• rework;
• poor scheduling;
• low staff utilisation;
• excessive overtime;
• senior staff completing junior work;
• weak project management;
• unrecorded time; and
• customer delays that create additional work.

The invoice may be higher, but labour cost can rise faster.

Businesses that sell time should compare estimated hours with actual hours by job. A project billed at £10,000 may look attractive until the time records show that it required £8,500 of labour and subcontractor cost.

6. Capacity has become inefficient

Growth often happens in steps rather than a smooth line.

A business may need to hire a manager, lease larger premises or buy software before the additional capacity is fully used. For several months, turnover may rise but not enough to absorb the new fixed costs.

This can be a planned investment rather than a failure. The problem arises when the business does not measure:

• the additional fixed cost;
• the expected contribution from growth;
• the break-even sales level;
• the time allowed to reach capacity; and
• what action will be taken if demand is slower than expected.

Expansion costs should be supported by a forecast and monitored against milestones.

7. New customers are less profitable

Customer numbers are not the same as profitable customers.

A large customer may negotiate lower prices, longer payment terms, special reporting, dedicated staff or frequent changes. The turnover looks attractive, but the cost to serve may be much higher than the contract pricing assumed.

Customer profitability should include:

• direct product or service cost;
• delivery and travel;
• staff time;
• onboarding;
• account management;
• returns or complaints;
• credit risk;
• financing caused by long payment terms; and
• any customer-specific software or compliance requirements.

The customer with the highest sales may not be the customer generating the highest profit.

8. Supplier costs are not being passed on

Businesses sometimes continue using old quotes after supplier prices have changed.

This is particularly dangerous where:

• materials are volatile;
• work is contracted at a fixed price;
• quotes remain open for too long;
• foreign exchange affects purchases;
• subcontractor rates change frequently; or
• customers require delivery months after the price was agreed.

Quotes should have expiry dates and, where appropriate, cost-escalation clauses. The estimating system should use current supplier data.

9. Waste, returns and rework have increased

Volume can expose operational weaknesses.

More orders may produce:

• more damaged stock;
• higher return rates;
• picking and packing errors;
• customer refunds;
• warranty claims;
• duplicated work;
• material waste; and
• overtime needed to correct mistakes.

If the accounting system records only gross sales and purchases, the true cause may remain hidden. Operational data should be reviewed alongside financial data.

10. Overheads have grown faster than expected

Gross margin may remain stable while operating margin falls because overheads have expanded.

Examples include:

• additional administration staff;
• higher rent and business rates;
• new software subscriptions;
• professional and compliance costs;
• marketing retainers;
• vehicles;
• management salaries;
• insurance; and
• finance costs.

Some overhead growth is necessary. The issue is whether the business receives the expected capacity, efficiency or revenue benefit.

Subscription costs are a common source of gradual margin leakage. Each item may seem small, but unused licences and overlapping systems can become material when combined.

11. Bad debts and slow payment have increased

Turnover can be recognised before customers pay.

If a business grows by offering longer credit terms, it may report higher sales and profit while cash becomes increasingly tied up in debtors. If some customers later fail to pay, bad-debt expense reduces profit.

The cost is not limited to the unpaid invoice. The business may also incur:

• credit-control time;
• collection costs;
• legal fees;
• interest on borrowing used to fund the gap; and
• lost capacity that could have served a better customer.

Debtor days, aged receivables and overdue balances should be reviewed with the margin report.

12. Finance costs have increased

Rapid growth often requires funding.

The business may need to finance stock, wages, equipment or the gap between completing work and receiving payment. Overdraft interest, loans, asset finance and merchant cash advances can reduce profit after the operating result.

Turnover may therefore rise with gross profit while profit before tax falls because the funding cost has increased.

The full cost of finance should be included when evaluating whether growth is creating value.

13. VAT has changed the economics

VAT can affect both pricing and cashflow.

The current UK compulsory registration threshold is more than £90,000 of VAT-taxable turnover, measured on a rolling 12-month basis, subject to other registration rules. HMRC’s VAT registration guidance confirms the threshold and timing requirements.

For a business selling mainly to VAT-registered customers that can recover VAT, registration may have limited impact on the customer’s net cost.

For a consumer-facing business, the effect can be more difficult. If a £100 selling price must remain £100 after registration, part of that receipt may become output VAT. The business must either:

• increase the customer price;
• absorb some or all of the VAT; or
• redesign the product, service or cost base.

Input tax recovery can offset some of the cost, but it may not fully protect the margin, particularly for labour-heavy businesses with limited VAT-bearing expenditure.

Crossing the threshold should be forecast before it happens. Artificially restricting or splitting activity to avoid registration can create separate tax and commercial risks.

14. Revenue has been recorded incorrectly

Sometimes the apparent margin problem begins with unreliable data.

Possible issues include:

• sales recorded gross of VAT;
• client money treated as company turnover;
• deposits recognised as revenue too early;
• credit notes missing;
• duplicated invoices;
• sales allocated to the wrong month;
• work in progress omitted or overstated;
• accrued income unsupported;
• intercompany sales counted twice in a group report; and
• costs posted to the wrong category or period.

Before making pricing or staffing decisions, the business should confirm that turnover and costs have been recorded consistently.

How turnover can mislead in different sectors

The same principle applies across industries, but the warning signs differ.

Professional and service businesses

Turnover growth may come from more client work, but margin can fall through underpricing, scope creep, low utilisation, senior staff doing routine tasks or time not being recorded.

Useful measures include:

• revenue per fee earner;
• chargeable utilisation;
• average realised hourly rate;
• write-offs;
• work in progress days;
• staff cost as a percentage of fees; and
• profit by client or service line.

Property management and serviced accommodation

Gross booking receipts or rent collected for owners should not automatically be treated as the management company’s turnover. The accounting depends on whether the business acts as principal or agent and on the contract terms.

Even where turnover is recorded correctly, margin can fall because of:

• platform fees;
• cleaning and linen costs;
• guest refunds;
• maintenance call-outs;
• utilities;
• channel-manager subscriptions;
• staff travel;
• pricing discounts; and
• low occupancy outside peak periods.

Unit numbers and booking value should therefore be assessed alongside net management fee, contribution by unit and cost to service each property.

Retail and e-commerce

Higher online sales can be offset by paid advertising, marketplace commission, shipping, returns, card fees and discounted stock.

The business should calculate contribution after channel-specific costs, not rely only on product gross margin before fulfilment and customer acquisition.

Construction and trades

Fixed-price work is vulnerable to material inflation, underestimated labour, subcontractor increases, delays, rework and disputed variations.

Contract turnover can rise while job margin falls. Each project should have an original budget, approved variations, costs committed to date, costs incurred, estimated cost to complete and forecast final margin.

Hospitality

Revenue may rise because of higher covers or occupancy, but margin can be reduced by food waste, agency staff, delivery commission, utilities and promotions.

Sales per labour hour, average transaction value, ingredient cost percentages and waste should be monitored frequently.

Agencies and intermediaries

Amounts invoiced to customers may include substantial pass-through media, contractor or supplier spend. A high turnover figure can exaggerate the scale of income actually retained by the agency.

The business should understand gross billings, recognised turnover, gross profit and net fee income separately.

Why annual accounts may reveal the problem too late

Statutory accounts are essential, but they are usually prepared after the financial year has ended. By the time falling margins appear in the annual figures, the business may have operated under weak pricing for many months.

Annual accounts also aggregate information. They may show that gross margin fell from 40% to 35%, but not identify whether the cause was:

• one product;
• a new customer;
• a particular branch;
• a sales channel;
• a supplier increase;
• a staff-efficiency issue; or
• a change in sales mix.

Monthly management accounts allow the business to investigate while decisions can still affect the current year.

For a growing or low-margin business, a monthly review is normally more useful than waiting until year-end. Some operational indicators may need weekly monitoring.

The numbers every growing business should monitor

The exact dashboard depends on the business, but it should usually include more than turnover.

Turnover movement

Compare actual sales with:

• the previous month;
• the same month last year;
• budget;
• forecast; and
• the volume and price assumptions behind the forecast.

Seasonal businesses should avoid drawing conclusions from a simple month-to-month comparison.

Gross profit and gross margin

Review both the pound value and percentage. A higher gross profit with a lower percentage can still be a warning if overheads and working capital rise faster.

Contribution margin

Calculate contribution by product, service, customer and channel where possible. This shows which sales genuinely help to cover fixed costs.

Operating profit and operating margin

This reveals whether overhead growth is absorbing the additional gross profit.

Average selling price

Track whether growth comes from higher volume, higher prices or a different mix. A falling average selling price may reveal discounting or movement towards lower-value work.

Direct labour and utilisation

Service businesses should measure staff cost, chargeable hours, recovery rate and project overruns.

Overhead ratio

Compare overheads with turnover and gross profit. Fixed costs may grow ahead of sales during investment, but the gap should be planned and temporary.

Debtor days and cash conversion

Profit that remains unpaid does not fund wages or tax. Monitor how quickly sales turn into cash.

Stock and work in progress

Rising stock or work in progress can absorb cash and hide slow-moving, obsolete or unrecoverable amounts.

Break-even turnover

Know the sales level required to cover fixed costs at the current contribution margin.

How falling margin changes the break-even point

The break-even calculation is:

Fixed costs divided by contribution margin percentage

Assume a business has monthly fixed costs of £18,000.

At a 30% contribution margin, monthly break-even turnover is:

£18,000 divided by 30% = £60,000

If contribution margin falls to 25%, break-even turnover becomes:

£18,000 divided by 25% = £72,000

The business now needs £12,000 more turnover every month simply to produce no profit and no loss.

This is why low-margin growth can feel exhausting. The company must process more work, fund more variable costs and manage more customers before the owners see any additional return.

How much must prices increase to restore a margin?

Businesses sometimes respond to a cost increase by adding the same cash amount to the selling price. That does not preserve the margin percentage.

Suppose a service sells for £100 and direct cost rises from £65 to £72. The old gross margin was 35%.

To retain a 35% margin, the required price is:

£72 divided by 65% = approximately £110.77

Adding only the £7 cost increase would produce a selling price of £107 and a gross margin of approximately 32.7%. To restore the original 35% margin, the price needs to rise to approximately £110.77.

Another useful calculation is the price required to achieve a target cash contribution:

Required price = direct cost plus target contribution

The business should also consider customer demand, competitor positioning, perceived value and capacity. A mathematical price is a decision input, not a complete pricing strategy.

How to diagnose falling margins

A disciplined review should move from data quality to commercial causes.

Step 1: Reconcile the figures

Confirm that sales, credit notes, direct costs, stock, work in progress, accruals and prepayments are complete and in the correct period.

Check that VAT and client money are treated correctly and that bank receipts have not been mistaken for turnover.

Step 2: Separate price, volume and mix

Ask how much of the turnover change came from:

• selling more units;
• charging a higher or lower price;
• discounts;
• different products or services;
• new customers;
• lost customers; and
• new sales channels.

This prevents the business from calling all sales growth “increased demand”.

Step 3: Compare direct cost per unit

Review supplier cost, materials, labour time, subcontractors, commission, shipping and other variable costs on a per-unit or per-job basis.

Step 4: Analyse margin by segment

Calculate gross or contribution margin by:

• product;
• service;
• customer;
• contract;
• location;
• property;
• team; and
• channel.

The overall percentage is an average. Segment analysis shows what changed beneath it.

Step 5: Review overhead movements

Compare each material overhead with budget and the previous period. Separate deliberate investment from uncontrolled cost growth.

Step 6: Distinguish recurring and one-off items

A one-off recruitment fee is different from a permanent increase in wages. Both affect the current result, but they require different responses.

Avoid dismissing repeated “one-off” costs. If exceptional costs appear every month under different descriptions, they are part of the operating model.

Step 7: Reconcile profit to cash

Review debtors, stock, work in progress, tax liabilities, loan repayments and capital expenditure. This identifies whether the business is profitable but cash-constrained, or whether weak cash reflects weak margin.

Step 8: Assign actions and owners

A useful review ends with decisions, responsible people and deadlines. It should not end with “keep an eye on costs”.

Actions that can restore profit margins

The correct response depends on the cause. Broad cost cutting can damage service quality without fixing weak pricing or sales mix.

Review prices systematically

Introduce regular pricing reviews using current costs and target margins. Consider tiered packages, minimum fees, rush charges and different prices for complex work.

Tighten discount authority

Require discounts above a set level to be approved with a contribution calculation. Track the total value and reason for discounts.

Reprice unprofitable customers and contracts

Use time and cost data to identify work that consumes more resources than expected. Renegotiate the scope, price or terms. In some cases, ending the relationship may improve profit and free capacity.

Improve sales mix

Direct marketing and sales effort towards products, services and customers with stronger contribution and strategic value.

Reduce scope creep

Define deliverables, revision limits, response times and chargeable extras clearly. Train teams to identify work outside the agreed scope before it is completed.

Improve labour planning

Match work to the correct skill level, improve scheduling, monitor overtime and address repeated rework.

Renegotiate suppliers

Compare suppliers, purchasing volumes, delivery terms and contract commitments. Do not focus only on unit price if reliability failures cause waste or customer refunds.

Review channels

Calculate net contribution after advertising, commission, fulfilment, returns and payment fees. A high-volume channel may be less profitable than direct sales.

Remove waste and duplication

Review software licences, manual processes, stock losses, repeated administration and avoidable errors.

Improve credit control

Set appropriate payment terms, invoice promptly, follow up consistently and assess customer credit risk before increasing exposure.

Reforecast capacity investments

If a new hire or location is not reaching the expected break-even point, revise the plan early. Decide whether to accelerate sales, change the cost base or pause further expansion.

When lower margins may be acceptable

A falling margin is not automatically a mistake.

A business may deliberately accept a lower percentage margin to:

• enter a new market;
• secure recurring revenue;
• use spare capacity;
• launch a new product;
• win a strategically valuable customer;
• clear obsolete stock;
• build a distribution channel; or
• invest ahead of growth.

The decision is stronger where management has defined:

• the reason;
• the expected duration;
• the total cash cost;
• the success measures;
• the route back to target margin; and
• the point at which the strategy will stop.

An intentional, funded margin reduction is different from discovering months later that the business has been underpricing its work.

The relationship between profit and cashflow

Profit and cash are different, but falling margins often put pressure on both.

Growth can consume cash because the business may need to pay for stock, labour and suppliers before customers pay. If each sale also produces less profit, there is less internal cash available to fund that gap.

A business can therefore experience:

• record turnover;
• reported accounting profit;
• an increasing debtor balance;
• larger VAT and payroll payments;
• higher borrowing; and
• less cash available to the owners.

Cashflow forecasts should reflect the new margin, payment timings, tax and growth costs. Using last year’s margin in the forecast can materially overstate future cash.

For a fuller explanation, read Cashflow Awareness for Business Owners: Why Profit Alone Is Not Enough.

Questions to ask before pursuing more turnover

Before accepting a major contract, launching a discount campaign or opening a new channel, ask:

1. What is the expected revenue?
2. What are the true variable and direct costs?
3. What contribution will remain?
4. Does the work require new fixed costs?
5. How much working capital is needed?
6. When will the customer pay?
7. What is the risk of returns, delays or bad debt?
8. Does the business have enough capacity?
9. What happens to existing customers and service quality?
10. What margin is required to justify the risk?
11. Is the quoted price protected against cost changes?
12. How will actual performance be measured?

Turnover should be pursued because it creates sustainable value, not because a larger sales figure looks impressive.

A practical monthly margin review

Each month, management should:

1. Complete and reconcile the bookkeeping.
2. Confirm revenue is recorded correctly and excludes VAT where appropriate.
3. Post stock, work in progress, accruals and prepayments.
4. Compare turnover with budget and the same period last year.
5. Calculate gross profit, contribution and operating margins.
6. Analyse the price, volume and sales-mix movement.
7. Review margin by product, service, customer or location.
8. Investigate material cost variances.
9. Review staff utilisation and project overruns.
10. Compare overheads with budget.
11. Check debtors, cash, stock and tax liabilities.
12. Update the full-year forecast.
13. Agree actions, owners and deadlines.
14. Review whether actions from the previous month were completed.

The report should be short enough to use but detailed enough to reveal what changed.

Common reporting mistakes

Celebrating percentage sales growth without a baseline

A 50% increase sounds impressive, but an increase from £10,000 to £15,000 may still be below break-even.

Comparing turnover that includes VAT with turnover excluding VAT

The figures are not comparable. Reports should use a consistent basis.

Reviewing gross profit pounds but not gross margin percentage

Gross profit can increase while the return from each sale deteriorates.

Reviewing only the total business

One profitable service can hide losses in another. Segment reporting is essential where margins differ.

Treating all costs as fixed

Costs such as commission, card fees, shipping and subcontractors often move with sales and should be included in contribution analysis.

Ignoring owner labour

A business may appear profitable because the owner works excessive unpaid hours. Pricing should reflect the cost of replacing or fairly rewarding that work.

Using outdated standard costs

If the accounting system values jobs using old material or labour rates, the reported margin may be overstated.

Focusing on accounting profit without cash requirements

Growth can be profitable on paper but unaffordable if payment terms and working-capital needs are ignored.

Treating every variance as temporary

A repeated adverse variance is evidence that the budget or business model needs revision.

Frequently asked questions

Can turnover increase while gross profit falls?

Yes. If direct costs increase faster than sales, both the gross margin percentage and total gross profit can fall. Heavy discounting or a move towards low-margin products can produce this result.

Can gross profit rise while net profit falls?

Yes. Additional gross profit may be absorbed by higher wages, premises, marketing, software, finance costs and other overheads.

What is a good profit margin?

There is no reliable universal percentage. A good margin depends on the sector, risk, capital employed, business model, growth stage and owner objectives. The business should compare with its own history, budget, credible sector data and the return required for the risk taken.

Is turnover the same as money received?

No. Under accrual accounting, revenue can be recognised before or after cash is received depending on what has been earned and the applicable rules. Bank receipts may also include VAT, loans, capital introduced or client money that is not turnover.

Should a VAT-registered business include VAT in turnover?

Turnover in the accounts is normally shown excluding VAT. VAT-taxable turnover for registration and scheme purposes follows specific VAT rules and should not be confused with a bank-receipt total.

How often should margins be reviewed?

Monthly is appropriate for many growing businesses. Weekly operational indicators may be necessary where sales volumes, input prices, stock, labour or project costs change quickly.

What is the difference between markup and margin?

Markup is profit expressed as a percentage of cost. Margin is profit expressed as a percentage of selling price.

If a product costs £60 and sells for £100, the markup is 66.7%, but the gross margin is 40%. Confusing the two can lead to underpricing.

Why did hiring staff reduce the margin?

The salary cost may begin before the new employee reaches full productivity or before sales use the extra capacity. Training, recruitment and management time can add further cost. The effect may be temporary, but it should be compared with the hiring plan.

Should we stop selling a low-margin product?

Not automatically. It may contribute towards fixed costs, attract customers who buy other profitable items or use spare capacity. Review its contribution, strategic role and opportunity cost before deciding.

Can raising prices improve profit if sales volume falls?

Yes. A smaller number of higher-contribution sales can produce more profit and require less working capital. The result depends on customer response, capacity and the price sensitivity of demand.

Why does the bank balance look healthy if margins are falling?

The balance may include VAT, unpaid supplier liabilities, loans, customer deposits or cash from previous periods. A single bank figure does not show current profitability or commitments.

Do higher sales always increase Corporation Tax?

Corporation Tax is based on taxable profit, not turnover alone. Higher turnover may not increase tax if allowable costs rise by the same amount or more. HMRC’s Corporation Tax overview explains that companies pay tax on taxable profits.

Can annual accounts show which customers are unprofitable?

Usually not on their own. The bookkeeping and management reporting need appropriate customer, project, service or department tracking.

The key message for business owners

Turnover growth is useful only when the economics of the additional sales are understood.

A business should know:

• the gross profit and contribution from each main activity;
• whether prices cover current costs;
• which customers and channels create value;
• how overheads change as the company grows;
• the break-even turnover at the current margin;
• how much working capital growth requires; and
• whether corrective action is producing results.

The most dangerous growth is not always falling sales. It can be rapidly increasing sales that generate too little contribution, consume cash and create operational pressure.

Turnover tells you how much business passed through the company. Margin tells you how much value the business kept.

PR Accountants can help business owners move beyond headline turnover and understand what is driving profit.

Our support can include:

• monthly or quarterly management accounts;
• gross, contribution and operating-margin analysis;
• customer, service, product or property profitability reporting;
• budget and forecast preparation;
• price and break-even modelling;
• cashflow forecasting;
• bookkeeping reviews and cost reclassification;
• VAT-threshold monitoring and registration planning;
• actual-versus-budget reporting;
• debtor and working-capital analysis; and
• regular management meetings focused on practical action.

If sales are increasing but cash and profit do not feel stronger, the answer is likely to be found beneath the turnover figure.
