Published Invoices

On publish, invoices are removed from Unprocessed Invoices and instantly posted to the customer’s invoice library and, simultaneously, exported to accounting, when using QuickBooks Online and Xero.
Published Invoices may also be exported to accounting from [Finance > Invoices > Published > More > Export to accounting].
No changes can be made to a Published Invoice. This is prudent accounting: the customer has downloaded it and posted it to their books. Discrepancies between your books and your customers could lead to serious problems.
Use credits or a new invoice [ Production /Late Order ] to make amendments to a Published Invoice.
