You can now create checkout rules based on the customer's billing address.

This makes it easier to control checkout behavior when the billing address matters more than the shipping address, such as billing ZIP/postal code, country, province/state, city, company, or phone number.

For example:

• Block checkout when a billing ZIP or postal code is not supported

• Show a validation message when billing details do not match your requirements

• Hide or rename payment methods for specific billing countries or regions

• Target B2B customers using the billing company field

• Create rules around billing information even when the shipping address is different

This gives you more flexibility to manage checkout rules around the billing details your customers enter.
