Use invoice deletion only when you intend to remove the document and its related records. It is not a way to refund a client.
Steps
Open the invoice and confirm the client, event and document name.
Preserve the records your business needs, including signed agreements, payment history and accounting information.
Open Options > Delete Invoice.
Read the confirmation and proceed only if deletion is the correct action.
Important financial effects
There is no self-service undo. The deletion flow can remove associated records and can affect a connected accounting invoice. Refund-history protections or permissions may block the action. Do not try to bypass a block by deleting payment records.
Deleting the document does not mean the payment processor returned money or cancelled a bank/card transaction. Use the supported refund process and verify its status separately. If you are unsure, ask the team before deleting.
