Must know
- Cancel returns no money; Refund returns money to the customer.
- Open a Draft, Unpaid, or Overdue invoice and you’ll see Cancel invoice; paid invoices show Issue refund. In the invoices list, a Draft shows Delete instead — that removes the draft for good.
- Refunds apply to any invoice where money has moved — Paid, Partially paid, or already Partially refunded; once fully refunded the invoice shows Refunded.
- Refunding a paid line defaults to Cancel & refund (ends the linked registration); switch to Refund only to return the money and keep it active.
- Draft / Unpaid / Overdue (nothing paid yet) → open the invoice and you’ll see Cancel invoice, which voids it; no money moves. In the invoices list, a Draft offers Delete instead — that permanently removes the draft rather than voiding it.
- Paid / Partially paid → Issue refund. Opens the line-item refund dialog, where you can either return money or cancel a line for $0.00.
