This is the most common shape of a stuck business, and the most demoralising, because effort is clearly going in. Margin leaves through four doors — the price you charge, the mix of what you sell, what it costs to deliver, and customers who consume more than they pay for. Almost nobody knows which door without looking.
Short answer: Profit margin rises once a business identifies which of four specific leaks—price, product mix, delivery cost or unprofitable customers—is responsible. Revenue growth often hides the damage because broad cost cuts quickly remove revenue-producing activity and leave the real sources untouched. Only profit measured by product, customer and channel shows which lever will work without side effects.
When margin is thin the instinct is to cut, and the first round usually works. The second round starts removing things that were producing revenue, and the third does real damage. Cost programmes reliably decay this way because they treat cost as a single number rather than asking which costs are attached to which revenue.
The alternative is unglamorous: work out profit per product, per customer and per channel. It is common to find a quarter of the customer base is unprofitable, and that the business has been funding it out of the good half.
Two businesses with identical prices and identical costs can have very different margins purely because of what proportion of each thing they sell. Shifting mix requires no price change and no cost cut — it changes what you push, who you target, and what you decline.
It is the least painful margin lever available and the one most often missed, because it is invisible unless you separate the numbers.
This question routes to Cost & Margin Improvement — one of 29 engagements the platform runs. It does not produce advice in general; it produces this analysis for your business:
✓ Breaks profitability down by product, customer and channel — where the leak becomes visible
✓ Separates costs that scale with revenue from costs that do not
✓ Tests whether price still matches delivered value, segment by segment
✓ Identifies unprofitable customers and what to do about them short of firing them
✓ Models the margin effect of a mix shift before you attempt one
✓ Ranks fixes by margin recovered per unit of disruption

It varies so widely by industry that the number alone tells you almost nothing — grocery runs on low single digits, software on very high ones. The useful comparison is against your own trend and against what your cost structure should permit. A margin that is falling while revenue rises is a signal regardless of its absolute level.
Price first, if there is room, because it goes straight to the bottom line and costs nothing to implement. Whether there is room is answerable: it depends on where you sit against alternatives and how much of your value is currently uncaptured. Cost work is slower and has a floor, but it is the answer when price is genuinely at ceiling.
Allocate delivery cost, service time and discount to each customer rather than looking at revenue alone. The pattern is usually consistent: the largest customers negotiate hardest and consume the most support, and often sit near or below break-even while appearing to be the best accounts.
