How to allocate one credit note to multiple invoices in Xero
Last updated: July 2026
Short answer: yes, a single credit note can be split across several invoices for the same contact, all from one screen. Allocating many credit notes in one action is a separate job — both are covered below.
Splitting one credit note across invoices
- Open Business → Credit notes (or Business → Bills to pay → Credit notes for supplier credits) and open the credit note.
- Choose Credit note options → Allocate credit.
- Xero lists every open invoice (or bill) for that contact. Type the amount to apply against each one — the running total updates as you go.
- Click Allocate credit to save. Any remainder stays on the credit note as unallocated credit.
The allocations post immediately: each invoice's balance drops by the amount you entered, and the credit note moves to Paid once fully allocated.
Limits to know
- Same contact only. A credit note can only be allocated to invoices belonging to the same customer or supplier.
- Same currency. Cross-currency allocation is not supported.
- Approved documents only. Draft invoices and draft credit notes don't appear on the allocation screen.
The real bottleneck: many credit notes
The screen above handles one credit note at a time. If month-end leaves you with dozens or hundreds of unallocated credit notes, each one goes through the same screen. For that volume, BulkOps (built by us) does the whole set in one run: it scans all unallocated credit notes and open invoices in your organisation, proposes contact-by-contact matches (exact amounts first, then oldest first), shows a full preview you can edit, then runs the batch as one job — with one-click undo and a CSV audit trail. Previews are unlimited and free; the first 25 executed allocations cost nothing.

FAQ
Can I allocate part of a credit note and leave the rest?
Yes. Enter any amounts you like on the allocation screen; the unapplied remainder stays on the credit note for later.
Can one invoice receive credit from multiple credit notes?
Yes — repeat the allocation from each credit note. The invoice's amount due reflects the sum of all allocations.
What if I allocated to the wrong invoice?
Allocations are removable — see How to remove a credit note allocation in Xero.
