Revenue Is A Vanity Metric. Margin Is The Truth.
Track gross margin per offer, not total revenue: many businesses grow revenue while shrinking profit because their most popular offer carries the highest hidden delivery cost.
The offer that's quietly costing you
Most service businesses have one offer that sells easily and one that pays well. When those are different offers, growth feels like exhaustion — the busier you are, the thinner the margin gets, and revenue charts keep pointing up while the bank account stays flat.
You cannot see this from a revenue line. You can only see it when cost of delivery is attributed honestly, including your own hours at a real rate.
How to calculate margin per offer in one afternoon
You do not need new software. You need one spreadsheet and ninety minutes:
- List each offer and its price actually collected over the last two quarters (not list price).
- Add direct costs: contractors, software specific to delivery, ad spend attributable to that offer.
- Add human hours, including yours, priced at what you'd pay to replace them.
- Gross margin = (collected − direct costs − labour) ÷ collected.
- Sort descending. The bottom row is your decision.
Three options for the bottom row
There are only three legitimate responses to a low-margin offer: raise the price, reduce the delivery cost through scope or process, or retire it. 'Sell more of it' is not on the list — volume multiplies whatever the margin already is.
Founders resist retirement because the offer carries identity. Ask a colder question: if you were buying this business tomorrow, would you keep that line?
The client-level version
Run the same maths per client. Most portfolios contain one or two accounts consuming disproportionate hours at below-average rates. Those clients aren't just unprofitable — they are the reason you have no capacity to sell the profitable work.
Questions founders ask
- What is a healthy gross margin for a service business?
- Productised and advisory services commonly sit between 50% and 80% gross margin once founder hours are costed. Below 40% usually signals underpricing or scope creep rather than a market problem.
- Should I include my own time as a cost?
- Yes. Excluding founder hours makes low-margin offers look viable and hides the real reason capacity never frees up.
- How often should I recalculate margin by offer?
- Quarterly, and always before launching a new offer or raising prices.
