Frequently asked questions
What is a debit memo?
A debit memo increases the amount a customer owes against an invoice already issued. It documents the reason and the additional amount without altering the original invoice.
Is a debit memo the same as a debit note?
Yes. Debit memo is the common term in the United States, debit note in the UK and Europe. The document and its purpose are identical.
When would you issue a debit memo?
Typically after undercharging, when extra work was agreed after invoicing, when a price was applied incorrectly, or to pass on a cost increase permitted by the contract.
How is a debit memo different from a credit memo?
They move in opposite directions. A credit memo reduces what the customer owes, a debit memo increases it. Both reference the original invoice.
Should a debit memo explain the reason?
Yes. An unexplained increase is the fastest route to a dispute. A clear reason and a reference to the original invoice make it far more likely to be paid without argument.
