Online Payment Links on Invoice. When creating an invoice for a customer I'd like a button to toggle on/off the online payment link attached to the invoice. This is because I sell some high priced items that I don't want paid for through an online card payment system as the fees are astronomical. But on lower priced items I don't mind. Currently I have to go through multiple steps to disable the online payment option, to then create and send the invoice, before having to go through all the steps to re enable it. .
