After you have created and submitted an invoice, you may find yourself needing to make updates or corrections at a later time. To do this, start by navigating to the action list associated with the specific invoice you wish to edit. Look for the option labeled "Edit" and select it. This will lead you to an editable form that displays all the information you initially entered when creating the invoice.

In the editable form, you will have the flexibility to modify various details such as the invoice date, billing address, line items, quantities, prices, and any additional notes or terms specified. However, please note that the invoice number is a unique identifier and remains fixed; it cannot be changed to maintain the integrity and consistency of your financial records.

It is crucial to understand that after you proceed to add a payment to the invoice, the system will lock any further updates to the invoice details. This restriction is in place to ensure the accuracy of your payment records and to prevent any discrepancies. Therefore, take the time to carefully review and make all necessary changes before you finalize any payments to ensure that all information is correct and up to date.
