What AddressPill does

AddressPill helps you avoid shipping errors in Shopify. It checks customer addresses at two moments:
  • In-checkout validation: before the order is placed
  • Post-checkout validation: after the order is placed
This means you can catch problems early, reduce manual work, and protect fulfillment quality.
