Why are we selling more but making less profit?

Extra sales only improve profit if they carry enough gross margin to cover the additional cost of winning and servicing them. Turnover is what you invoice. Gross profit is what remains after cost of sale. The gap between the two moves every time a price is discounted, a supplier increase is absorbed rather than passed on, a rebate is missed, or a low-margin account grows faster than the rest of the ledger. Below that line, extra volume usually adds cost: more deliveries, more hours, more stock to hold. So a business can invoice more, work harder and still finish the month with less profit than the year before. The useful question is not how much sales have grown, but what quality of sales has been added.

Why is turnover increasing but gross profit isn’t?

This is normally a margin and mix question rather than a sales question. Gross profit is turnover minus cost of sale, so it falls behind when the average margin percentage on new business is lower than on existing business. Common contributors include discount being approved more freely to win volume, growth concentrated in competitive product groups or project work, supplier price increases not reflected in sell prices quickly enough, rebate and buying-terms income not tracked against the volume that earned it, and credits or returns rising with activity. None of these proves the cause on its own. The pattern worth measuring is gross profit percentage by branch, by product group and by customer, compared with the same period last year rather than against budget alone.

Why are we busier but not making more money?

Busy measures activity. Profit measures what activity leaves behind. Merchant businesses can absorb a lot of extra work before it shows in the accounts: more quotes, more small orders, more special purchases, more deliveries to more sites, more time spent chasing and correcting. Each of those consumes labour, transport and management attention, which sit in operating cost rather than cost of sale, so they reduce operating profit without changing gross margin. Very often the additional workload comes from the lowest-value end of the customer base. Being busier is therefore consistent with earning less, and the test is whether gross profit per employee, per branch and per delivery has moved in the same direction as volume.

Why isn’t increased turnover improving EBITDA?

EBITDA is earnings before interest, tax, depreciation and amortisation, so it reflects both gross profit and the operating cost of running the business. Turnover can grow while EBITDA stands still because the extra gross profit generated is smaller than the extra cost required to generate it. Additional drivers, wages, overtime, agency cover, hire, fuel, and the cost of holding and handling more stock all land in operating cost. Growth can also raise cash pressure without touching EBITDA at all, because stock and debtors absorb cash rather than profit. If EBITDA is flat on rising turnover, it is worth separating the gross profit movement from the operating cost movement before drawing any conclusion about which one is responsible.

How can I improve profit without chasing more sales?

Many merchant businesses have opportunities to recover profit from existing trade before relying on additional sales. Pricing discipline usually comes first: how consistently supplier increases are passed through, how much discretionary discount is given and by whom, and whether special prices are reviewed once the job that justified them has ended. Then customer and product mix: which accounts and product groups actually earn their gross margin once delivery and handling are included. Then stock and buying: obsolete lines, overstocks and missed rebate thresholds all convert into margin. Finally the cost of service: delivery runs, small-order handling and credits. Much of this can be measured using information the business already holds or can assemble, and none of it depends on winning an additional sale.

How do I get managers to understand the difference between sales and profit?

Managers tend to focus on what is consistently measured, discussed and rewarded. If the daily conversation is mainly about sales value, that is what they are most likely to protect. The change is usually less about training and more about what appears on their report and in their review. Show gross profit value and percentage alongside turnover, broken down where they have genuine influence: their branch, their customers, their discount decisions, their stock. Make the trade-off visible, for example what additional volume would be needed to recover the profit given away by a discount. Give them authority limits they understand, and hold the conversation about margin as consistently as the conversation about sales. Understanding becomes stronger when the information, expectations and accountability are clear and consistent.

Why does a profitable branch sometimes still feel under pressure?

Profit and cash are different things, and pressure is usually felt in cash, workload and control rather than in the profit and loss account. A branch can report good gross profit while holding too much stock, carrying slow-paying accounts, absorbing a heavy delivery commitment, running short-handed, or depending on one or two people to hold everything together. Reported profit can also flatter a branch if central costs, transport or stock write-offs are not fully reflected in its numbers. So a profitable branch under strain is not a contradiction. It is a prompt to look at working capital, cost allocation, workload and key-person dependency rather than only at the margin line.

What you may be seeing

Turnover ahead of last year while gross profit value or percentage is flat or behind.
More discount requests, more special prices, and older special prices still in force.
Noticeably different margins between branches on similar trade.
Stock value growing faster than sales, with more slow-moving and obsolete lines.
Supplier increases arriving faster than sell prices are adjusted.
Delivery, overtime, agency or hire costs rising with activity.
Credits, returns and pricing queries increasing.
Sales talked about daily; margin discussed mainly at month end.
Profit targets missed in branches that everyone agrees are busy.
Cash tighter than the reported profit would suggest.

None of these on its own identifies the cause. Together they indicate where evidence is worth gathering.

What good looks like

Gross profit value and percentage reviewed with the same discipline as turnover, at branch level and by the people who influence them.
Discount authority defined, understood and visible, with special prices reviewed and time-limited.
Supplier increases passed through promptly and deliberately, with exceptions made knowingly rather than by default.
Customer and product profitability understood after delivery and handling costs, not just at invoice margin.
Stock held deliberately: known availability priorities, obsolescence dealt with, buying terms and rebates tracked.
Operating cost growth explained by the profit it supports.
Branch managers accountable for margin, cash and control, not volume alone.
Reporting that lets you see where profit moved, and why, without a month-end investigation.
Performance that does not depend on one or two individuals holding it together.

What may be happening underneath

Pricing discipline.: Discount authority, price file maintenance and pass-through of supplier increases vary by person and by branch.
Customer mix.: Growth concentrated in accounts that buy competitively, order in small quantities, or require frequent delivery.
Product mix.: Volume shifting towards lower-margin groups, project or contract work, or special purchases with thin cover.
Supplier terms and rebates.: Buying terms, rebate thresholds and settlement discounts not tracked against the volume that should have earned them.
Stock.: More stock, more obsolescence, more write-off and more cash tied up, with availability problems still driving expensive buying-in.
Cost to serve.: Delivery runs, handling, returns and credits consuming margin that never appears as a price reduction.
Labour and operating cost.: Additional hours, cover and management time added to support volume rather than profit.
Branch controls.: Stock accuracy, pricing authority, credit control and housekeeping applied unevenly across sites.
Management focus.: Reporting, incentives and daily routine built around turnover rather than gross profit and cash.

These are the usual drivers, not a diagnosis. Which ones apply, and in what order, is an evidence question specific to your business.

Questions worth asking

01Which branches have moved most on gross profit percentage against the same period last year?
02Has average discount increased, and which decisions or people account for the change?
03Are supplier price increases being passed through consistently, and how quickly?
04Which customers have grown fastest, and what margin do they carry once delivery and handling are counted?
05Which product groups are driving the volume growth, and at what margin?
06Has stock grown faster than sales, and what proportion is slow-moving or obsolete?
07Are rebate and buying-term thresholds being tracked and achieved?
08What has happened to gross profit per employee and per branch?
09How many special prices remain active beyond the job that justified them?
10Is cash movement consistent with the profit being reported?

If these questions are difficult to answer from current reporting, that in itself is worth knowing.
