With an option to 'Pay Now' the customer would click on a link from the invoice that was emailed. This would allow the customer to make the payment in timely manner and would could link the payment to the AR invoice as paid. Payment options could be by bank account, credit card an/or additional methods.
I agree with Cody; when is this planned for? The initial post was back in 2020. Quickbooks and many other software providers have this capability so I think it is very doable. This way clients can pay when it is convenient for them, not just during business hours. Much more secure as well, as they are entering their own cc information.
I see this is planned, which our organization is excited at the prospect but I'm hoping someone is aware of a timeline for the addition of this feature. It would help us plan accordingly with stopgap solutions such as 3rd party subscriptions.
