Automatically register payment and generate invoice when amount is zero

Question

When pressing the "Confirm Sale" button, even if the total amount to be paid is zero (because of the 100% discount), the Register Payment popup is getting displayed - and I need to press Cancel in the popup to proceed (generate invoice & and mark it as paid).

Can I bypass displaying the popup - automatically generate the invoice and mark it as paid?

Please let me know.

Thanks.

There are two ways you can achieve this.

1. Write a module to overwrite the buttons named Create Invoice method and call a method to check if the total amount is zero then prepare the invoice values and automatically generate the invoice and view if needed. The rest with non-zero amount should follow the wizard path.
2. Create an automated action, where you can filter the SOs which are confirmed and has zero total and automatically create the invoices. You can combine this with scheduled actions to check it every X minutes or hours. This can be tricker than explained and may require some coding in the action.
