Frequently asked questions
The customer kept more than we invoiced — how do I bill it?
Issue a debit note referencing the invoice for the extra units at their price, with tax, showing the invoiced vs delivered quantity. It bills the variance cleanly.
What if it was our over-delivery?
If the customer agrees to keep and pay for the extra, a debit note bills it; if they return it, use a return process instead. Confirm which before charging.

What is the difference between a debit note and a credit note?
A debit note increases the amount owed on an invoice already issued — for an undercharge, additional charges or interest. A credit note does the opposite: it reduces or cancels what is owed. Buyers also raise debit notes to notify a supplier of a return or a claim.
