Can I save an invoice as a draft and finish it later?

Yes. You can save the invoice as a draft before finalising it. Use a draft while you are waiting for a billing address, purchase-order reference, agreed amount, or other detail. Do not send an incomplete draft as the final payment request.

When you return to it, review the whole invoice again, not just the field you were waiting for. Check dates, client details, quantities, currency, totals, and receiving-account details before finalising and sending it. If you cannot find a saved draft, contact support with the client name and when you prepared it. Avoid creating and sending a second invoice until you know whether the first one was issued.
