Which of your services actually make money?

Most service businesses know their total revenue and their biggest clients. Far fewer know which services actually make money once the cost of delivering them is counted — and that gap quietly shapes the business.

Why revenue by service misleads

It's natural to judge services by how much revenue they bring in, but revenue says nothing about what's left after delivering the work. A service that generates a lot of top-line revenue at a thin margin can contribute less profit than a smaller service with a healthy margin — and it often consumes far more of your team's limited capacity to do it.

Breaking gross profit and margin out by service line fixes this blind spot. Once you see the profit each service actually produces, the picture frequently rearranges: the 'flagship' offering everyone is proud of may be subsidising the business's time rather than funding it, while an overlooked service turns out to be the real earner.

What counts as the cost of a service

Gross margin depends on charging each service its true direct cost — the costs that exist only because you deliver that service. That means the labour hours at their cost, any subcontractors, software or tools bought specifically for it, materials, and third-party fees. It does not mean company-wide overheads like office rent or admin salaries, which sit below gross profit and shouldn't be loaded onto a single service.

The most common mistake is undercounting labour. If a service quietly eats far more hours than it's priced for, its margin is worse than the invoice suggests — the cost is real even though no one wrote a cheque for it. Costing each service's delivery honestly, especially the time, is what makes the comparison trustworthy.

Reading the margin table

With revenue, direct cost, gross profit, and margin laid out per service, patterns jump out. High-revenue, low-margin services are candidates for repricing or tighter scoping. High-margin services are the ones to promote, package, and sell more of. Low-margin, low-revenue services that also drain time are often the easiest to drop entirely.

It also helps to look at the blended margin across everything you do — the total gross profit as a share of total revenue. That single number is a fast health check, and watching it move as your mix of services shifts tells you whether you're steering toward more profitable work or away from it.

What to do with the answer

The point of the exercise isn't to rank services for its own sake — it's to change what you sell and how you price it. Once you know which services pay, you can lean your marketing and sales toward them, reprice or re-scope the thin ones, and stop offering the work that costs more in time than it returns. Small shifts in the mix toward higher-margin services compound quickly into a healthier business.

The free calculator shows the gross profit and margin for a single service instantly, and the full tracker compares every service you offer so you can rank them by profitability rather than revenue. It's assumptions-driven and not financial advice, but it turns a hunch about which work pays into numbers you can act on.

A quick worked example

Imagine two services: one bills $5,000 with $2,200 of direct cost, the other bills $1,500 with $1,100 of cost. The first keeps $2,800 at a 56% margin; the second keeps $400 at about 27%. On revenue the first looks four times bigger; on margin it's not just bigger but far more efficient — every dollar of the first service's revenue keeps roughly twice as much profit.

Now suppose the low-margin service also takes nearly as many hours to deliver. It's occupying capacity that a higher-margin service could use. Seeing that trade-off in black and white is what lets you make the call to reprice it, streamline it, or replace it with more of the work that actually pays.
