Somebody is standing at your counter saying they paid that last month. You are fairly sure they did not. There is no version of this conversation that goes well if it becomes a contest between two memories, because one of you has to be wrong and neither of you wants to be the one to say so.
The useful move is to stop it being about memory at all.
Most of these are honest
It is worth starting from the assumption that the customer believes what they are saying, because usually they do. The common cases are mundane: they paid, but for the visit before; they paid part and remember it as all; a family member paid and told them it was settled; or they are thinking of a different shop entirely.
Someone deliberately trying it on is rare, and even when it happens, the response is the same. You do not need to work out which situation you are in. You only need to look at the record together.
Turn the screen around
This sounds trivial and it is the whole technique. Reading a balance out loud is you asserting something. Turning the screen so they can see the dated list is both of you reading the same thing. The first invites an argument; the second usually ends one.
- Open their ledger, not just their balance. The individual entries are what carry the answer.
- Read down the dates with them, out loud, in order. Very often they interrupt you themselves at the entry they were thinking of.
- If they paid part, show the entry and what remained after it. That is usually the exact point of confusion.
- Do not editorialise. The list is doing the work; adding "so you see, you did not pay" turns it back into a personal argument.
A balance is a claim. A dated list of what happened is an explanation. People argue with claims and accept explanations.
When your record is the one that is wrong
It happens. A payment taken during a rush and not entered, a settlement applied to the wrong customer, a sale recorded as paid that was not. If the ledger has a gap where the customer says a payment was, treat that as a real possibility rather than a challenge.
If the record is genuinely ambiguous and neither of you can resolve it, splitting the difference is usually the right commercial answer. You are not adjudicating a case; you are deciding whether this relationship is worth more than the disputed amount. For a regular customer it almost always is.
Preventing the next one
- 1
Confirm the new balance out loud when credit is given
"That takes you to two thousand four hundred." Four words at the moment of the sale, and both of you have now agreed on a number on a specific day.
- 2
Give a receipt that shows what is still owed
Not just what was bought. The outstanding figure on their copy is the thing that prevents the disagreement two months later.
- 3
Record payments at the counter, not at closing time
The payment that gets forgotten is always the one taken during a rush and entered later. That forgotten payment is the source of most disputes where the customer turns out to be right.
- 4
Send a monthly statement to your larger accounts
A customer who sees their balance every month cannot be surprised by it in six months. It also surfaces disagreements while they are small and recent.
