Admitting a bookkeeping error to a client goes best when you say it early, plainly and with the fix already done. Name what was wrong, which months and reports it touched and how much it moved. Then show the corrected figures and the one change in your process that keeps the same error from happening again.
What to say first when admitting a bookkeeping error
The first sentences of an error message state the mistake and take ownership of it, with no lead-in. "I found an error in your books that I made" is a better opening than a paragraph of context. Clients read the first two lines closely and skim the rest, so the admission and its size belong there.
A good opening answers three questions in order:
- What happened. "I coded your loan payments entirely to interest expense."
- Where it shows. "This affects your January to March reports."
- How big it is. "Your reported profit for those months was 4,350 lower than it should have been."
Avoid passive phrasing such as "an error was made." It reads as hiding who made it. Avoid blaming the software or the bank format unless that truly caused it, and even then say what you should have caught. Clients forgive a mistake far more readily than they forgive a sense of being managed.
Tell the client before they find it. An error the client discovers, or that their tax preparer raises, costs more trust than the same error you report yourself.
How should a bookkeeping error correction be shown to the client?
A bookkeeping error correction is shown with a short before-and-after for the figures the client actually looks at: profit, a key expense line and any balance that changed. The corrected reports go with it. A client should be able to see in one glance what moved and that the books now tie to the bank.
Keep the evidence to what the client needs. A full journal of correcting entries is for your file and for the tax preparer if they ask. The client needs the effect, in their terms. If previously sent reports changed, say which ones to discard. Clients who saved the old version will otherwise compare against wrong numbers.
When the fix moved amounts between accounts, the client may ask why a familiar number changed. Explaining reclassified transactions to clients covers how to walk through a line that moved from one account to another.
A sample message admitting a miscoded bookkeeping error
The message below is an example for an example client, a small bakery whose equipment loan payments were coded entirely to interest expense for three months. The figures are made up for illustration. Each payment was 1,800.00, of which about 1,450.00 was principal.
Subject: A correction to your January to March books
Hi Dana,
I made an error in your books that I want to tell you about straight away. I coded your three equipment loan payments in full to interest expense. Most of each payment was principal, which reduces the loan rather than counting as an expense.
The effect: your profit for January to March was understated by 4,350.00 in total. Your loan balance was also overstated by the same amount.
As reported Corrected Interest expense, Jan to Mar 5,400.00 1,050.00 Net profit, Jan to Mar 11,200.00 15,550.00 Equipment loan balance, Mar 31 42,350.00 38,000.00 I've corrected all three months and checked the loan balance against your lender's statement. The updated reports are attached; please use these instead of the earlier ones.
From now on I split each loan payment using the lender's statement before I post it.
I'm sorry for the mix-up. Happy to go through it on a call if that would help.
Mark
Notice what the message leaves out: no long explanation of how loan amortization works and no list of reasons the error was understandable. If Dana wants the detail, she will ask.
The process change that keeps a bookkeeping error from repeating
The process change is a specific new step that would have caught this error, written into your checklist the same day. "I'll be more careful" is not a change. "I reconcile each loan balance to the lender's statement every month" is, because it would have surfaced the error in January instead of April.
Match the change to the cause:
- A miscoding rule. Fix the rule itself, so the next payment from that vendor posts correctly without you remembering.
- A missed reconciliation. Add the account to your monthly close checklist, with a named source document to tie it to.
- A rushed close. Look honestly at workload. A bookkeeper carrying more clients than the hours allow will make more errors of every kind; how many clients a bookkeeper can handle helps you work out where that limit sits.
Tell the client the change in one sentence, as in the sample. It shows the error led somewhere.
When is a bookkeeping error too small to raise with the client?
A bookkeeping error is too small to raise when it moved no report the client has seen, or moved one by an amount that changes no decision. A 12.00 coffee coded to supplies and fixed before the month closes needs no message. Anything already reported, anything touching tax figures or anything the client may act on should be raised.
Agree the threshold in advance rather than deciding case by case. A line in your engagement or in your client communication policy such as "I correct small coding changes under 100.00 in the next report without a separate note" means a minor fix never looks like something hidden. Setting expectations with bookkeeping clients covers how to agree those terms at the start.
Errors that start on the statement side, such as a missed line or a wrong amount, are easier to stop before they reach a report. AutoBankConvert checks that the opening balance plus each statement's transactions equals the closing balance, and flags a statement that fails rather than exporting it.
