Walk into any ten person agency in Brooklyn or the Flatiron District and ask the owner which client is their most profitable. You’ll get an answer. Ask how they know, and the answer gets vaguer.
That gap matters more here than almost anywhere else, because the cost side of an agency’s business in New York is unforgiving. Senior creative talent is expensive, the commercial rent is expensive, and the clients are sophisticated enough to negotiate hard. A retainer that quietly stopped covering its work eighteen months ago is not a rounding error in that environment.
A lot of small shops are repricing right now. The ones doing it well have numbers. The ones doing it badly are guessing, and guessing tends to produce two specific errors: raising the fee on a client who was already profitable, and leaving the actual problem account untouched because the relationship feels good.
Why retainers drift
The mechanism is well understood and almost nobody prevents it.
A retainer is priced against an assumed scope. Over time, the work expands by increments that each seem too small to raise: an extra round of revisions, a quick social asset before a launch, a report nobody asked for in the original agreement, a weekly call that was supposed to be monthly. None of these are unreasonable individually, which is exactly why they accumulate.
The second source is internal. Hours spent on proposals, internal reviews, team meetings and account admin come out of the same payroll as the client work. When nobody measures how much of the week goes there, billable utilisation declines while the salary cost stays flat, and the agency feels busier and poorer at the same time.
Neither of these is visible without a record. By the time it shows up in the bank balance, a year of mispriced work has already been delivered.
How agencies measure client profitability
The firms repricing from evidence rather than instinct have done one unglamorous thing: they track hours against a client, project and task, and they separate billable work from internal work at the point of entry.
That structure is what makes the two useful reports possible. The first sets billable revenue against labour cost per client, which produces margin by account rather than margin across the agency. The second compares estimated hours against actual, which shows where the proposal was wrong and by how much.
Tools built for agency work are organised this way. actiTIME, for example, lets an agency set time, billing or labour cost budgets at client or project level to match each retainer, shows a progress bar as hours consume the budget, and can notify managers before an estimate or budget is exceeded. Every entry is tagged billable or non billable, so client work and internal activity are separable in reporting rather than blended.
It isn’t the only option, and the right one depends on whether your bottleneck is billing, resourcing or project management. This comparison of time tracking software for agencies runs through the main contenders and what each is actually suited to, which is worth reading before committing a team to anything.
The budget alert is the part that changes behaviour. Knowing a retainer is 80 percent consumed with two weeks of the month left is a scope conversation you can still have. Knowing it afterwards is just a loss you’ve already taken.
The repricing conversation is easier with a number
This is the practical payoff, and agency owners consistently underestimate it.
“We need to revisit the fee” is an assertion, and clients treat it as an opening position in a negotiation. “The retainer assumes roughly 40 hours a month and we’ve averaged 61 over the last two quarters, here’s the breakdown by activity” is a different kind of conversation. It stops being about whether the agency deserves more money and becomes about which of the two variables, the fee or the scope, the client would prefer to change.
In my experience most clients choose scope more often than agencies expect. They had no idea they were asking for that much, because nobody was counting on either side.
When to reprice a retainer client
A reasonable sequence for a small shop.
Track hours properly for one quarter, including internal time, with no change to how anyone works otherwise. Apply real cost rates, including the senior people whose hours are the expensive ones. Then rank every client by margin, worst to best.
That ranking almost never matches the revenue ranking, and the mismatch is the whole point. It tells you which accounts to reprice, which to rescope, which to leave alone, and occasionally which to let go, a decision far easier to make with a number attached than with a feeling.
For agencies operating on New York cost structures, the difference between knowing that and assuming it is usually the difference between a difficult year and a fine one.
