Bas, thanks for the reply.

First I add after line 67. When generating the bill appeared “Internal error”. I tried after line 77, but the situation was the same. In both cases, the invoice number was increased.

I am doing something wrong? After what line to copy instruction?

Thank you. Solved

Bas, where we can add:

if ( $document->order->get_total() == 0 ) return;

File bewpi-document.php seems no longer exist.

Why not leave permanently in the plugin?

Best regards

Thank Bas, it works!!!

Congratulations for your plugin and support.
