We implemented Address Validation iO across multiple client stores and saw an immediate drop in return-to-origin shipments. The app is lightweight, doesn’t interfere with the checkout flow, and catches issues like PO boxes or missing house numbers before the order is placed. It's also significantly more affordable than competitors and scales well across stores. Support was responsive and helpful when needed. Review collected by and hosted on G2.com.
Initial integration into some custom themes required manual configuration, but once implemented, the solution has been stable and low-maintenance. A bit more onboarding documentation for developers would be helpful for edge cases. Review collected by and hosted on G2.com.
