Good morning, I'm doing a payment area, where the user can buy a monthly product and a single purchase product, the project owner demands that the payment be the same for both forms, it can be on credit card or Bank slip. But it does not make sense to pay a product that is paid every month in installments with a single purchase. Would anyone have any suggestions?
Good day, I think here should be a another process (with identical UI Design and logic, differing in a few variables getting from the api (in this case, the price and subscription period).
In step back you should ask the user (for example, radio button) which version of the subscription he wants to use.
Of course this UI wireframe is only example, when you spent time on this, i'm certain You find better & easier solution.
