Return on a Hire: How a Professional Services Firm Can Tell If Its Last Investment Paid Off

The problem: You made two sizeable investments last year, a hire and a software purchase, and you cannot say what either one gave back.

The solution: Connect what people bill, what clients cost to serve, and what your tools are actually used for, so the next hire or purchase is decided on evidence instead of instinct.

Sometime in the next few months a partner is going to walk into your office and say the team is drowning and needs another person. The month after that, a vendor is going to offer you a system that promises to take a week of work out of every busy season. Both requests will be reasonable. Both will be expensive. And you will make both decisions the same way you made the last two, which is by talking it over and going with your gut, because there is no version of the answer sitting anywhere that you could look up.

That is the uncomfortable part. Not that the decisions are hard, but that you have made this decision before, twice, and you still cannot say how those went.

The decision arrives before the evidence does

Every firm your size has a story about the last hire. The story is usually that it worked out, or that it was rough at first and then settled. Notice that the story is about the person and how things felt afterwards, not about what changed in the numbers.

The honest test is duller. In the year after that hire, did the firm bill more, or did the same work get spread across more people? Did the partners get back the hours the hire was supposed to free up, and did those hours go to client work or absorb into administration? Did anything the firm previously turned away start getting accepted?

Those are answerable questions. They are just not answerable quickly, and the moment for asking them passes. Twelve months later the hire is simply part of the firm, the counterfactual is gone, and the answer becomes whatever everyone remembers.

Why the accounting system does not settle it

The books tell you what you spent. They will show the salary, the licence fee, the implementation cost, all of it correctly recorded to the right period. What they do not show is the other side, because the return on a hire or a system is not a line item. It shows up as billed hours that would not otherwise have existed, or as work that stopped taking as long, or as a client the firm could keep instead of losing.

That evidence exists in the firm, in pieces. Time entries know who worked on what. The billing side knows what was invoiced and what got written down before it went out. The client records know which relationships grew and which quietly shrank. The trouble is these pieces are kept for different purposes by different people, so the connection that would answer the question, this person's time led to this work for this client at this realization, is one nobody has ever needed to make until the moment they need it badly.

What an answer would actually require

For each kind of investment, the evidence is a small number of things joined together. The joining is the whole difficulty.

The decision	What you would need connected	The question it answers
A senior hire	Time by person and client, realization on that time, partner hours before and after	Did capacity turn into billed work, or just into more people doing the same work?
A practice management or workflow system	Hours logged against the tasks it was meant to shorten, before and after	Did the week it promised to save actually come back, and to whom?
Taking on a new service line	Cost to serve and realization by client for that service	Is the new work earning what the existing work earns, or subsidised by it?
Keeping a large legacy client	All hours and write-downs against that client, across every engagement	Is the biggest client one of the most profitable, or one of the least?

None of these need new information. They need existing information joined up and kept current, which is what organizing the data and automating the upkeep is for. When time, realization, and client cost stay connected on their own, the before-and-after picture is simply there when someone asks. When they do not, producing it means a week of someone's evenings in a spreadsheet, which is why it never happens and why the last two decisions have no verdict.

The purchase nobody goes back and checks

Software has a particular failure mode worth naming. A firm buys a system to solve a problem, uses maybe a third of it, and keeps paying for all of it. Nobody goes back a year later to ask whether the promised hours came back, because the person who championed it has moved on to the next thing and revisiting it would mostly be embarrassing.

The result is that the licence renews forever. It is not a large number in any one month, which is exactly why it survives. A firm your size can carry several of these at once, each defensible on its own, and the aggregate is a real amount of money committed to tools whose value has never been tested. The same connected picture that tells you whether a hire returned anything tells you which systems are genuinely load-bearing and which are being paid for out of habit.

A look at a professional services firm

Consider an accounting firm doing about $6 million a year with 40 people. Last year it added a senior manager and replaced its practice management system. Both were sensible calls at the time. Asked today whether either one paid off, the managing partner would give an impression rather than a number, and would be aware that it is an impression.

Suppose the firm connected the pieces: time by person and by client, realization on that time, cost to serve each engagement, and usage of the systems it pays for. Looking back over the two decisions, you would expect a mixed picture rather than a clean verdict. The hire is likely to show real added capacity, with a meaningful share of it going into work at lower realization than the firm's average, which is a different result from either "it worked" or "it did not". The system is likely to show that the hours it saved were saved, but in one department rather than across the firm, which changes what the next licence renewal is worth.

The value of that is not the retrospective. It is that the next decision, the partner asking for another person, gets made against something. A senior hire at about $120,000 loaded is roughly $360,000 over three years. A firm that knows the last one produced capacity at below-average realization is in a position to hire differently, or to price differently, or to decide the constraint was never headcount. A firm without that evidence commits the same $360,000 on the strength of a feeling and will be in exactly this position again in a year.

Three questions worth being able to answer

You do not need a project to find out where you stand. Ask three questions and see how long the answers take to produce.

The first is which five clients earn the firm the most per hour actually worked, including the hours written down before the invoice went out. The second is what changed in billed work in the twelve months after your last hire. The third is which of the systems you pay for is used by more than half the people it was bought for.

If each takes a week of someone's time to assemble, that is the finding. The information is all there, and it is arranged in a way that puts it out of reach on the timescale decisions actually get made. That is what makes the next investment a guess, and it is the part that can be changed.

The takeaway

The money question underneath all of this is not what the firm spends. It is where the next dollar should go and what it costs to be wrong about it. A hire, a system, a new service line, and a client you keep out of loyalty are all investments, and a firm that cannot grade the last ones will keep making the next ones on instinct. The evidence is already inside the business, sitting in time entries, billing records, and client files that were never connected to each other. Connect them, keep them current without anyone maintaining it by hand, and the question stops being a matter of opinion before the next decision arrives rather than after it.
