Project Margin Hit a Five-Year High. The Cost of Running the Firm Grew Twice as Fast as Revenue.

Delivery has never been more profitable. The firm has never been less rewarded for it. The difference between those two sentences is a subtraction, and it points at a single line in the accounts.

Project margins across professional services firms have reached 37.7 percent, a five-year high, up from 35.9 percent the year before. Over the same stretch, firm EBITDA moved from 9.8 percent to 9.9 percent.

Delivery improved by nearly two points. The firm kept one tenth of one point.

Subtract the two published numbers

Project margin is measured on the engagement, before the cost of everything that is not an engagement. EBITDA is measured after. The difference between them is, by definition, what a firm spends in order to exist: non-billable staff, finance and administration, marketing and business development, premises, systems.

The overhead load used to be 26.1 points of revenue. It is now 27.8.

Stated that way it sounds like a rounding matter. It stops sounding like one when you put revenue growth beside it. Revenue grew 5.2 percent. For a cost that consumes 26.1 points of a smaller revenue base to end up consuming 27.8 points of a larger one, the cost itself had to grow roughly 12 percent. More than twice the rate of the business it supports.

The 12 percent is arithmetic on two reported margins and a reported growth rate. It is not something anybody surveyed, and no firm publishes it, which is most of the reason it goes unnoticed.

Every instrument points at the engagement

Consider what a professional services firm actually measures. Utilization. Realization. Project margin. On-time delivery. Revenue per consultant. Every one of those is an engagement metric, and firms have spent five years getting genuinely better at all of them. The 37.7 percent is real, and it was earned.

The cost of running the firm is not measured that way. It is a residual. It appears once a month as a total, it is compared to last month, and it looks fine because it always looks roughly like last month. Nobody owns the trend line, because the trend only becomes visible when you subtract two numbers that live in different reports.

So a firm can run a five-year improvement program on the half of the business it can see, and hand the entire gain to the half it cannot.

What growth was supposed to do

The reason firms tolerate a heavy back office is the belief that they will grow into it. Overhead is treated as fixed, revenue is treated as the variable, and the plan is to let the numerator do the work.

Test that. Hold the cost of running the firm flat in dollars and let revenue grow 5.2 percent. The 27.8 points of revenue it consumes fall to about 26.4, and EBITDA lands near 11.3 percent instead of 9.9. The gap between those two figures, roughly 1.4 points of revenue, is the entire dividend from a year of growth, and it was spent before it arrived.

A dividend spent before it arrived is the part worth sitting with. The growth was real. The margin improvement was real. Neither reached the bottom line, because the thing that was supposed to stay fixed did not stay fixed.

What the twelve percent is made of

In firms of five to a hundred and fifty people, back-office cost is rarely a department. It is distributed. It is the partner assembling a bill from three systems on a Sunday. It is the administrator working an aged receivable list by hand and getting through the top third. It is a monthly reporting pack rebuilt from exports every month because nothing connects. It is intake, document collection and status chasing on a new client, absorbed by whoever is nearest.

None of that shows up as overhead on an org chart. It shows up as senior time that is not billable, and it grows every time the firm adds work, which is precisely why it tracks revenue instead of staying fixed.

How CXO Solves This

Financial Back-Office Operations handles the mechanical half directly. Invoice assembly, extraction and matching, AP and AR processing and payment workflows run as agentic steps on a fixed cadence rather than as senior staff time, which is where the cost genuinely sits in a firm this size.

Reporting and Intelligence Automation closes the measurement gap that let this happen. When the cost of running the firm is monitored as a rate against revenue rather than as a monthly total, a 12 percent line inside a 5 percent business is visible in the first quarter it appears, not five years later in a benchmark.

Neither of these adds a point to project margin. Project margin is already at a five-year high. They change how much of it survives the trip to the bottom line.

In most operations, far more work can be automated than leadership realizes. One discovery call is enough to size what automating it would return to your bottom line. Book it at https://cxocorporation.com/contact.
