Firstly, I would like to know how, as an agent, I can create an order and send an invoice to a customer. The customer should be able to make payment directly from that invoice. For example, I would send them an invoice for 1 red hat, and they would have the option to pay from their side.
Secondly, how can I hide the invoice payment method from regular customers who are not agents? I want this payment method to be visible only to agents and not to regular customers.
Lastly, I would like to inquire whether it is possible to customize the invoice or if it is limited to the default invoice sent through your plugin.
Thank you again for your help
