How to add "buy on credit" to Journal 3?

Hello! I need to add new button in product page (and in cart and checkout page too if it is possible) to buy on credit which must send info about selected product(s) and client’s info to bank. How it can be done in Journal? As I can see you can only add extra buttons that work as simple links.

What you're asking for could be quite a bit of work so I suggest you pay a developer from the Commercial Support Forum or email us info@antropy.co.uk
