I want to remove the option to pay by credit card for B2B customers on the website. I only want them to see the “Submit for Review” option at the checkout.
Shopify recently purchased Checkout Blocks and made the base plan FREE for Plus users. I was able to test what you wanted and could get it to HIDE the Shopify Pay portion.
You should be able to simply disable the credit card payment method. I just did this yesterday in a b2b store I’m doing some work on. It just has a single manual payment method. In your case since you’re using payment terms you shouldn’t need any payment method at all.
The only bad part of this app is that when you fulfill the order and send the invoice they can see the credit card option. Not the wire transfer option.
