Debit Memorandum Definition in Three Scenarios

What Is a Debit Memorandum?

A debit memorandum, or “debit memo,” is a document that records and notifies a customer of debit adjustments made to their individual bank account. The adjustments made to the account reduce the funds in the account but are made for specific purposes and used only for adjustments outside of any normal debits. The reasons a debit memorandum would be issued relate to bank feesundercharged invoices, or rectifying accidental positive balances in an account. The opposite of a debit memorandum is a credit memorandum.

Understanding a Debit Memorandum

A debit memo is issued for three general cases: a reduction in a bank customer’s account balance due to fees and other related charges, under-billing of goods or services from a seller to a buyer, or an internal offset to a minor credit balance in a customer account. These types of situations are typically referred to as bank transactions, incremental billing, and internal offsets, respectively.

Bank Transactions

In retail bankinga debit memorandum is given to an account holder indicating that an account balance has been decreased as a result of a reason other than a cash withdrawal, a cashed check, or use of a debit card. Debit memos can arise as a result of bank service charges, bounced check fees, or charges for printing more checks. The memos are typically sent out to bank customers along with their monthly bank statements and the debit memorandum is noted by a negative sign next to the charge.

Incremental Billing

In business-to-business transactions, a debit memo is issued as an adjustment procedure following an inadvertent under-billing of goods or services provided to a customer. It is intended to correct a billing error. In formal parlance, it is notifying a customer that the debit memorandum will be increasing their accounts payable. For instance, if ABC Co. fills an order for XYZ Inc. and invoices the customer in an amount that is short of the agreed amount, ABC Co. will issue a debit memo to XYZ Inc. to indicate and explain the balance due.

Internal Offset

Within a firm, a debit memo can be created to offset a credit balance that exists in a customer account. If a customer pays more than an invoiced amount, intentionally or not, the firm can choose to issue a debit memo to offset the credit to eliminate the positive balance. If the credit balance is considered material, the company would most likely issue a refund to the customer instead of creating a debit memo.
