I'm setting up Ubercart on a Drupal 7 - upgraded site that originally used Commerce to allow customers to register for premium access to the website (granted via their user role).
On the D7 site I used the contrib module "Commerce Custom Offline Payments", which allowed me to add payment methods for deferred payment and manual update by admin. For example, the customer could choose 'Standing Order' or 'Direct Bank payment', and then be directed to relevant pages with further instructions. This didn't allow automated online payment (eg like PayPal) but that was fine. On receipt of the relevant detail from the customer (by email) the admin could then manually adjust their role.
In trying to replicate this behaviour with UC, I'm looking for advice on how to add two extra custom payment methods (Standing Order and Direct Bank payment). I'm sure this must be possible but I don't quite know where to start. I can deal with the notification via Rules, as long as I can identify what payment method was selected at checkout.
Thank you for your advice, if you have any! If there is a better way of doing what I'm trying to achieve (in BackdropCMS), I'd love to hear it.
