Checkout rules are Supercycle’s checkout validation in Shopify. The validation runs against every cart and blocks checkout when a rental, membership, or availability requirement isn’t met, so a customer can’t book an item that isn’t available or remove a required deposit. Keep it turned on. The rule is turned on under Checkout rules on Checkout in your Shopify settings.

​
Validations

The Supercycle rule checks the following before a customer can complete checkout:
  • Unavailable items. Requested quantities don’t exceed available inventory for rental items.
  • Deposit requirements. Required deposit products are in the cart for rental items.
  • Card authorization. A vaulted payment method is available when the rental requires one.
  • Account requirement. The customer has an account for membership rentals, unless they’re buying a membership plan.
  • Multiple memberships. Only one membership line in a cart.
  • Membership combinations. Membership rentals and non-membership rentals aren’t mixed for the same item.
  • Credit allowance. The customer doesn’t exceed their membership credit limit.
  • Start date consistency. Items with the same selling plan have matching start dates for a given duration.
  • Fixed dates. When fixed dates are on, every rental item in the cart has matching start and end dates.
  • Fulfillment constraint. Rental items are fulfilled from the location the customer selected at checkout.
