Once a task or expense has been invoiced, what can you do in Xero?

When a task or expense has been invoiced in Xero, it reflects that the transaction is officially recorded and a request for payment has been sent to the client. While it is not possible to delete the invoice or completely edit it after invoicing for compliance and accounting integrity reasons, users are allowed to add more time to a task without altering the already invoiced amounts directly.

This means you can expand the project’s scope by adding additional work hours to tasks, which will then be reflected in future invoices or adjustments, but you cannot make changes to the previously recorded invoice itself. Adding more time helps in more accurately billing the client if additional work was performed after the initial invoice was issued, thereby maintaining transparency and ensuring all work is accounted for.

The other options would imply making significant changes to already finalized transactions, which is restricted to maintain accurate financial records and prevent confusion in accounting practices.
