A debit memo, also called a debit note, is a document or transaction that increases the amount owed on an account. The term appears in three distinct contexts, which is the main source of confusion: on a bank statement it is a deduction from your balance, in accounts receivable it is a seller billing more than the original invoice, and in accounts payable it is a buyer documenting a deduction from payment.
On a bank statement, a debit memo is a charge the bank has applied to your account, reducing the balance. It is the bank debiting you rather than a customer or supplier transaction. Common causes include:
In bank reconciliation, debit memos are one of the standard adjustments: they appear on the statement but not in the company's cash records, so they must be recorded before the two will agree.
EXAMPLE
A statement shows a $35 debit memo for a returned deposit. The business records it by debiting Bank Charges $35 and crediting Cash $35, bringing the ledger in line with the statement.
A force pay debit memo is a bank transaction that must post and clear immediately, regardless of whether the account holds sufficient funds. The bank marks the item as force pay so it cannot be returned unpaid, and the account goes negative if the balance does not cover it.
It typically appears in a few situations: a cashed check that the bank has already given value for, a recovery of funds the bank previously advanced, or an item the bank is contractually obliged to honor. A related label, force pay debit memo recovery offset, indicates the bank is recouping an amount it had credited earlier.
For an account holder the practical consequence is that the item cannot be stopped or returned, and any resulting overdraft fees still apply. If a force pay debit memo appears unexpectedly, the bank is the only party who can explain the specific item behind it.
The two are mirror images. A credit memo reduces the amount owed. A debit memo increases it. Both adjust an existing transaction rather than replacing it, so the original document stays on the books alongside the adjustment.
A debit note and a debit memo are the same document under different names, with debit note more common outside North America.
A supplier issues a debit memo when the original invoice was too low and they want to bill the difference without cancelling and reissuing the whole document. Common reasons are omitted freight, an outdated unit price, more units shipped than billed, or contractual late fees.
EXAMPLE
A supplier invoices $12,600 for a delivery, then realizes $480 in freight was omitted. Rather than voiding and reissuing, they send a debit memo for $480. The buyer now owes $13,080 across two linked documents.
A buyer issues a debit memo to tell a supplier they are reducing payment and why. It is the documented version of a short-pay: instead of quietly paying less and leaving the supplier to work out the gap, the buyer states the deduction and its basis up front. Typical grounds are damaged or rejected goods, short shipments, agreed rebates, and compliance chargebacks.
EXAMPLE
A distributor is invoiced $28,400 but 18 cases arrived damaged, worth $1,260. They issue a debit memo for $1,260 and remit $27,140. Because the deduction is documented and referenced on the remittance, the supplier can apply it rather than opening a collections case for the shortfall.
The entry depends on which side you are on and what the memo covers. Three common cases:
Short-paying an invoice without a debit memo is the single most common cause of supplier payment disputes. The supplier receives less than the invoice amount, has no explanation, and records the balance as still outstanding. Their collections process then contacts a buyer who considers the invoice fully settled.
EXAMPLE
A buyer deducts $1,260 for damaged goods but sends no debit memo and no remittance detail. The supplier records a $1,260 unpaid balance. Six weeks later the two teams are reconciling statements to identify a deduction that was entirely legitimate and simply never documented.
