A founder of a forty-person consultancy sat down with me last year, convinced his problem was utilisation. Three years of revenue growth, profit going the wrong way, no clear answer to where it had gone. We picked a single recently-delivered project and walked through it together. The proposal had eaten eight hours of his director’s time, none of it logged. The scope had grown by roughly fifteen per cent over the project, none of it billed. The original quote had been discounted ten per cent against a competitor whose pricing he had never actually seen. The all-in margin came out negative. He had been doing this for eighteen months without knowing.
He is not unusual. Across service businesses at ten to a hundred staff, the same diagnostic shows up: revenue up year on year, profit flat or down, founder working harder, no one able to point at where the margin went. The cause is almost always the same, and once you see it, the pricing decisions that felt aggressive turn out to be the only ones that work.
Why is your service business busy and unprofitable?
Because the visible cost of delivering a project, the labour billed against it, is a fraction of the true cost. Sales overhead, proposal time, free consultations, scope creep, and concession discounts all eat margin invisibly and never show up on the project line. By year-end the founder works harder, takes on more work, and the gap between revenue growth and profit growth widens with no clear line to point at.
This is not a finance problem in the bookkeeping sense. The bookkeeping is fine. The problem is that activity-based costing is rarely done at project level in service firms, and the firm is making pricing decisions on a fraction of the relevant data. Scoro’s research on misaligned metrics frames it neatly: growth falls apart when no one agrees on what the business data actually means, not because of lead volume.
What are the four hidden costs eating margin?
Four costs run underneath every project and rarely appear on the project line. Pre-sale time, scope creep, senior-level work done at junior-level rates, and concession discounts to win against price-matching. Each one feels small in isolation. Stacked together on a real project, they often flip the sign on the margin line, which is why founders looking at the books cannot find the leak. The leak is structural, not a single line item.
Pre-sale is the largest of the four. Anthem Strategists’ analysis of service-firm pricing puts it bluntly: quick consultation calls that last an hour, multiple meetings before signing a contract, detailed proposals that take days to create, with a close rate of one in three, make two out of every three pitches completely unpaid work. None of it appears on the won-project P&L. All of it is real cost.
Scope creep runs at ten to twenty per cent of deliverables added without a change order, according to PCI’s agency-operations research. Senior-on-junior-rate is the partner who steps in to recover a deliverable that was scoped at junior time. Concession discounts compound the rest, often agreed to win against a competitor whose pricing the founder has never actually verified.
How does the maths actually look on one project?
It looks worse than the founder expects, almost every time. Anthem Strategists’ walk-through is the cleanest illustration. A service firm charges out at 150 dollars per hour against true all-in costs that include sales, overhead, and unbilled work. The actual margin lands at minus 66 dollars per hour. That is structural unprofitability dressed up as a busy year, invisible at aggregate level because the wins and losses cross-subsidise each other on the books.
The formula itself is simple. Project profit equals project revenue minus project costs, all in. Project margin equals project profit divided by project revenue, expressed as a percentage. The discipline is not the maths, it is including every cost in the cost line: the eight hours of director time on the proposal, the unbilled scope, the senior hours done at junior rates, the discount agreed at quote stage. The numbers reveal themselves on one project. They reveal a pattern across two.
Why are your loyal clients the least profitable ones?
Because long-standing clients almost always sit on rates that no longer reflect cost. UK input costs in professional services have moved over the last few rate cycles, salaries, software, and overhead all up, while legacy rates stayed where they were set. Anthem Strategists put the typical gap at fifteen to twenty per cent. The loyal accounts you have protected for years are quietly the lowest-margin work on the book.
Founders avoid this conversation because it feels uncomfortable. The legacy client trusted you when others did not, paid you on time, referred two more accounts. Raising their rate feels like correcting them. It is not, and naming the gap is the first move. Holding clients on legacy rates indefinitely is a charity decision, worth recognising as one. The kindness has gone on too long, and the rest of the book is subsidising it.
The price conversation is a re-anchor rather than a blanket increase. New rates for new work go to the current standard. Legacy clients move up over an agreed period, with the conversation handled openly, framed as rebalancing rather than correction. The clients who walk away on principle are usually the lowest-margin ones already, and the maths will confirm it on the way out.
What changes when you make the maths visible?
The strategic questions become answerable. Which clients are actually growing the business. Which projects to take and which to walk away from. Which services to invest in. Which to retire. Without project-level margin, these decisions are guesswork dressed up as judgement, and the founder ends up working harder on a portfolio that quietly works against them. With it, the questions get answers, and the answers get pricing decisions that hold.
The first move is not a finance overhaul. Pick one recently-delivered project. Calculate actual revenue minus actual costs, all in, including pre-sale time and scope drift. Compute project margin as a percentage. Do the same for one more. The pattern usually reveals itself in two data points. From there, the rate-card conversation, the legacy-client conversation, and the which-projects-to-take conversation all become tractable in a way they were not before.
If you are running a service business with revenue growing, profit not, and no clear story for where the margin went, the cost is rarely in the books and rarely about utilisation. It is in the four costs that never show up on the project line. The fix is to make them visible, one project at a time. Book a conversation.
