Hi,
Are you looking to confirm the invoice using a server action or allocate payments againts the invoice ?

If confirming invoice from list view, if not exist by default, you can add a server action and call the same function which get called from button.

For allocating, its not easier, you can check the reconcilation screen.


Thanks

Dear Azhar look i have more customer invoices i don't want manually open each one after then click to add to until paid the invoice I want the server action to automatically paid all customer invoices
