Frequently Asked Questions
Does a credit note sync to my accounting system?
If you have an accounting integration enabled (such as Xero, MYOB, or QuickBooks), the credit will sync to your accounting system on the next sync cycle, keeping both systems in balance.
Can I undo this change to the invoice?
You can update the invoice again by following the same steps. If the invoice has already been finalised or synced to your accounting system, contact your administrator about the best approach.
Will this change affect existing invoices for this customer?
Changes to customer details apply to future invoices. Existing completed invoices retain the details that were on the invoice at the time it was created.
