A second invoice doubled what my client owes: how to send a new invoice without adding to the booking total

Every invoice you issue on a booking adds to what the client owes for that booking, so a second invoice for the full price really does bill the client twice. Here is how to resend an invoice without adding to the total, bill again for only what is still owed, and fix a wrong one.

Why the amount due looked doubled

A booking's Balance Due adds up the invoices you issued on it. Unsent drafts and voided invoices used to be counted too, so a booking with a draft next to the sent copy of the same invoice showed twice its price. Now only issued invoices count: drafts and voided invoices are left out of Balance Due and out of the Owing figure on your bookings list. Two issued invoices for the same full price still add up to double, because the client was sent both.

Just need the client to get the invoice again?

Do not create a new one. Open Invoices (under Operations, in the Money group), click the invoice, and click Email again, or Email it if it was never emailed. You can tick Attach a PDF copy first. Copy link gives you the page where the client sees and pays it. The total does not change.

Bill for what is still owed

1. Open the booking and click Invoice in the row of buttons under its title.
2. The New invoice window opens. If the booking already has invoices, a yellow note says how much "is already invoiced on this booking" and lists them by number.
3. The first line is priced at only what is left, and the note says so: "The price below is the" amount "still unbilled" of the booking price.
4. If the note says the existing invoices cover the full price, "so a new invoice would bill the client again", only go ahead if this is for something extra.
5. Click Create draft. Nothing is sent yet.
6. Open the draft on the Invoices page and click Send.

That note counts drafts too, so delete an old wrong draft first (see below) to see the true amount left.

Replace a wrong invoice

• Still a draft: open it on Invoices and click Edit to fix the lines, or click Delete and then Delete draft. Keep it backs out.
• Already sent, nothing paid on it: KM Hub does not let you edit or delete it, because your client has seen it. Void it instead. Open it on Invoices and click Void. A window asks Void and the invoice number. Click Void invoice to confirm, or Keep it to back out. The invoice stays in your records marked Voided, your client sees it marked void and can no longer pay on it, and it stops counting toward what they owe for the booking. Voiding cannot be undone. Then create the correct invoice from the booking as described above: the amount already invoiced no longer includes the voided one.
• Already paid, in full or in part: there is no Void button, because money has been taken against it. Submit a support ticket from inside KM Hub with the invoice number and what it should say, and a person on the KM Hub team will reply.

Split one invoice into payments instead

If you wanted a deposit now and the rest later, keep one invoice and give it a schedule. Open the invoice, find Payment schedule, and click 50% / 50%, 50% / 25% / 25% or Custom…. Adjust the rows, use Add installment if you need more, tick Auto-remind the client if you want reminders, then click Save schedule. The installments must add up exactly to the invoice total.
