How to price bookkeeping cleanup work

By Peter Edwards ACMA CGMA · Chartered Management Accountant in practice

Cleanup work has a particular way of punishing generosity. The prospect describes "a few months behind, nothing major"; you quote something reasonable; and in week two the books reveal what they actually are. From that point every extra hour is yours to absorb, because renegotiating mid-engagement is miserable and most of us simply don't. The fix isn't quoting higher — it's quoting differently.

Rule one: the project and the retainer are different products

A cleanup engagement is two jobs wearing one agreement. The project is the one-off corrective work: the stocktake and correction, the suspense clearance, the DLA substantiation, re-reconciling the bank. The retainer is the ongoing monthly bookkeeping once the books are sound. They have different cost drivers — the project is driven by what's wrong, the retainer by transaction volume — and blending them into one monthly number is the classic mistake: the project overruns, the retainer subsidises it, and eighteen months later you're still resenting a client who thinks everything is fine.

Quote them separately, on paper, always: a fixed or ranged project fee with a defined scope, then a monthly retainer that starts when the project ends.

Rule two: price from findings, not from vibes

The project fee should be assembled from what a structured review of their exports actually found — which means doing that review before quoting, not after signing. Each finding type has a natural pricing unit:

• Suspense and unallocated balances: per item. Pull the listing and count — forty entries is a different job from four hundred, and the count is on their own paper.
• Missing or plugged stock: a defined package — stocktake support, valuation, correction journal, first months of the new routine.
• DLA substantiation: a fixed fee for the classification exercise, with tax work priced after, once the balance is understood. An unexplained DLA is unpriced risk; say so in the quote.
• Reconciliation backlog: per account per month behind.

Ranges are honest and clients accept them — "between X and Y depending on what the suspense listing contains" — provided the trigger for landing high or low is stated.

Rule three: quote a diagnosis, not a number

The strongest pricing move available costs nothing: give the prospect the findings in writing before the fee. One page — what's wrong, why each item matters, what fixing it involves. A number on its own invites haggling; a number attached to a diagnosis invites relief that someone finally understands the problem. It also quietly qualifies the prospect: the ones who argue with the findings themselves are showing you the engagement they'd be.

Rule four: know your walk-away signals

Some cleanups shouldn't be priced at all — they should be declined. Records the client won't hand over, a director whose answers change between conversations, hostility to the findings, or pressure to "just make it balance" — each is a preview of the engagement. The review that produced your findings is also your due diligence; let it work in both directions.

The sixty-second version of rule two

All of this depends on seeing the findings before you speak — which historically meant an hour or two of unpaid review per prospect. That's the part worth automating.
