Unapprove

Xero cannot send an approved invoice or bill back to draft. Unapprove does it in bulk: it makes a draft copy of each document you select, attachments included, then voids the original. You see a preview of every document first, with the reason any are skipped, and you type the count to confirm. It can also export attachments and invoice PDFs as dated ZIPs. Free to preview and to process 3 documents, then $39 a month or a $49 one-off pass.
