This is called "creating a manual payment gateway" in Commerce 2.
Unfortunately, the docs page is blank. 😓
So, here's how I set up bank transfer payment collection for Japan.
- Create a new payment gateway at
- Set the Plugin to Manual.
- Fill in the rest of the info as needed for your setup.
- Continue to configure your store in Commerce, and use the manual payment gateway (with any other payment gateways you require-- for example, I give users the option of bank transfer or credit card via Stripe).
