Management Accounting for a Consulting Firm

A consulting firm sells the most expensive resource there is — the time of its experts. And that's exactly why its finances are deceptive: rates are high, revenue is solid, yet somehow profit at the end of the month is modest. The reason is almost always the same: nobody actually measures how much an hour of a consultant's time really costs and how much of it is left over.

Management accounting for consulting answers three questions: how much each project earns, how busy your people are, and whether there will be enough cash. Let's break it down.

Why revenue in consulting isn't profit yet

Consulting revenue is billable hours multiplied by your rate. But between the client's rate and your profit sit the expert's salary, their unbilled hours, admin, and sales. A firm can bill $80/hour and still break even if half of the team's time isn't paid for by clients. We explained the difference between accounting for the tax office and accounting for decisions in Management Accounting: What It Is and Why an Owner Needs It.

Step 1. Measure margin by project and by client

Tie client payments and direct costs to every project: team hours in money, subcontractors, travel. That's how you get project margin — the key number in consulting. Next comes client margin: it often turns out that a big client with a discount and endless revisions brings in less than a quiet project.

Step 2. Watch your team's utilization

In consulting, profit depends directly on utilization — the share of billable hours. If an expert is on projects 60% of the time and \"idle\" the other 40%, the rate has to cover that. Without tracking hours you don't see this and chronically underprice your services.

Step 3. Plan your cash ahead

Consulting projects are long, payments come in stages, and salaries are due every month. That's a classic source of cash gaps. A payment calendar shows them in advance — how to build one.

Where to start

Set up your projects and clients, spend a month measuring margin and logging hours — and for the first time you'll see the real economics of your services. For an example of how a project-based business reached 173% profit through accounting — the case study is here.
