How do I regenerate an invoice?

Updated 8 Sep 2026

Open the job. Fix the lines. Click Regenerate Invoice (draft) or Generate New Invoice (if the last one was already sent or paid).

1. Open the completed job.
2. Add or edit services (see How do I add services or a discount on a job?). You cannot change lines while a live sent or paid invoice is locked to those lines — regenerate or create a new draft first.
3. If the invoice is still Draft, click Regenerate Invoice. Same draft, no new number. The work certificate updates too.
4. If the invoice is already Sent or Paid, click Generate New Invoice. You get a new unnumbered draft. The old finalized invoice stays.

Then send or mark paid as usual (see How do I send an invoice or download the PDF? / How do I mark an invoice as paid later?).
