Non-sufficient funds check

Working definition

A customer check the bank refused to honor for lack of funds, which reverses cash the entity had already recorded and restores the amount as a receivable from the customer.

Also calledNSF check · Returned check

A customer pays with a check. The entity debits cash and credits accounts receivable. Then the check bounces.

The economics went backwards: the entity does not have the cash and the customer still owes the money. The entry reverses the original one, debiting accounts receivable and crediting cash. If the bank charged a fee for handling the return, it is usually charged on to the customer, which raises the receivable further.

On a reconciliation the item goes on the book side, subtracted. The bank already knows the check failed and has already removed the money; the entity is the one whose records are wrong, so an entry is required.

A returned check is a credit event, not just a clerical one. A customer whose check bounced is a customer whose next invoice deserves a closer look when the allowance for credit losses is estimated.

For a $2,800 returned customer check, debit Accounts Receivable and credit Cash for $2,800 under the stated facts. Match the bank debit to the original deposit and customer before posting. If the bank also charges a fee, decide from the agreement whether the entity bears it or has a supported claim against the customer. The reconciliation identifies the missing book event; it does not decide collectibility or authorize a customer charge.
