Payment Rules for WooCommerce

Not every payment method belongs on every order. Cash on delivery makes no sense on a three-hundred-dollar order. Bank transfer is useless to a customer in a country your bank cannot receive from. Wholesale customers should see an invoice option and nobody else should. WooCommerce gives you a list of payment methods and one switch per method, so everybody sees the same list.

This puts rules on that list. A rule is some payment methods plus some conditions, and it either hides those methods when every condition is true, or shows them only when every condition is true. Every rule is listed on its settings screen as a plain sentence, such as "Hide Cash on delivery when the cart total is $200.00 or more.", so you can read down the list and check what your shop is doing without opening anything.

Rules can use conditions on the cart total, the shipping country and whether the customer is signed in. The cart total can count the items after discounts, with tax if your shop shows prices with tax, or the whole order including shipping, tax and fees. You choose, once, on the same screen. An empty cart never matches a cart total condition.

The rules are applied where WooCommerce builds its list of payment methods, so the classic checkout and the Checkout block both follow them, and they update as the customer changes their shipping method, country or coupon. A payment method that any rule hides stays hidden, and rules only ever take methods away from the list WooCommerce was going to show. A customer cannot get round a rule by posting a method that is not on the list: WooCommerce refuses the order, on the classic checkout and on the Checkout block. PayPal Payments' express buttons build an order without going through the checkout, so this refuses those itself when a rule hides PayPal. The rules do not apply on the page where a customer pays for an order that already exists, because there is no cart to judge.

Pro goes further. It has no limit on the number of rules, and adds conditions on the shipping method (a kind of method such as every flat rate, or one method in one shipping zone), on the customer's role (every role on your site, including custom ones, and guests), on the products in the cart (a product covers all its variations, and on a product page the product being viewed counts) and on the product categories in the cart (a category covers its sub-categories).

Pro also takes the quick-pay button of a hidden payment method off the page. In the Cart and Checkout blocks, an express button registered with the block in the standard way goes when its payment method is hidden: PayPal and Stripe's Apple Pay, Google Pay and Link were checked. On the classic cart, on product pages and in the mini-cart, PayPal's buttons follow the rules too, including the newer ones that ignore WooCommerce's own list. A payment method that already follows the list, such as Stripe's buttons on the classic pages, needs nothing from this plugin. The choice is one tick, and the hidden method's order is refused whether it is ticked or not.

If a Pro licence lapses, nothing is deleted and nothing stops. Every rule already written keeps hiding and showing payment methods, including rules that use Pro conditions or go past three. What stops is changing what Pro added: a new rule past three, a new Pro condition, editing a rule that uses one, and taking away express buttons. The licence screen lists exactly what is being left as it is.
