Debit Note

What is a debit note?

A debit note increases the amount a client owes you. If you need to add charges after sending the original invoice—perhaps for additional work, materials, or a price adjustment—a debit note documents the increase. It's the opposite of a credit note, which reduces amounts owed.

When to use debit notes

Debit notes are appropriate for:

• Additional work — Scope expanded beyond the original invoice
• Price corrections — You undercharged on the original invoice
• Additional materials — Extra supplies required
• Late fees — Penalties for overdue payment
• Shipping charges — Delivery costs not included originally

Debit note vs. new invoice

For small additions related to an existing job, a debit note keeps everything connected to the original transaction. For substantial additional work, a separate invoice might be clearer. Use judgment based on what will be easiest for your client to understand and for your records to track.
