fix it cleanly :-)

Refund or adjust without editing the invoice

A returned item, an overbilled hour, a goodwill discount after the fact. Issue a credit note against the original invoice, apply it to a future bill or leave it unused, and the invoice itself stays untouched.

Original invoice stays exactly as sent

Editing a sent invoice breaks the paper trail

Quietly changing the numbers on an invoice you already sent muddies your records and the client's. A credit note keeps the original exactly as sent and records the adjustment as its own document, applied against that invoice or a future one.

How it works

Create it against an invoice

Pick the client and the amount, the same way you build any invoice.

Apply it or leave it open

Offset it against the next invoice for that client, or keep it as a standing credit.

The original stays untouched

No editing what was already sent. The adjustment lives as its own record.

Track applied versus unused

Filter by Applied, Unused, or Void, with a running total of outstanding credit.

Every adjustment tracked, nothing edited after the fact

Apply a credit right on the next invoice

Pick an unused credit note when you build the client's next invoice and it comes straight off the total. The math is done for you, and the credit is marked used.

Questions

Does a credit note change the original invoice?

No, the original invoice is untouched. The credit note is a separate document that offsets it.

Can I use a credit note against a different invoice than the one it was issued for?

Yes, an unused credit note stays available for that client and can be applied to any of their future invoices.

Can I cancel a credit note?

Yes, void it and it is excluded from your outstanding credit total, kept in your records for reference.

Is this included in the plan?

Yes, unlimited credit notes, included at the one flat price.
