Hi Claudia,
Our plugin can change the order status based on payment gateway. In your case, I think Changing the order status to “Draft” could potentially resolve the problem you’re facing, setting an order to “Draft” status essentially removes it from the standard order processing flow and prevents it from being shown in the WooCommerce admin orders list. So, if it’s okay for you, then after installing the plugin, please go to the “RULE #1” and set the “Status from” to “Pending payment” and status to “Draft”. Then set an appropriate value for “Time trigger” option. Finally scroll down to the “Order Payment & Shipping” section and set the “payment gateways” to “PO payment gateway”.
Please give it a try. But let us know if it doesn’t work for you.
Kind regards,
Moshtafizur
