We built this to solve a frustrating ecommerce issue — would love your thoughts!

Hey everyone 👋

A while ago, I kept getting failed deliveries and "return to sender" issues in my Shopify store. Most of the time, it was because of small address mistakes from customers — missing house numbers, wrong postal codes, PO boxes in restricted areas, etc.

So I built Address Validation iO (AViO) — a lightweight app that checks and validates addresses directly in the Shopify checkout. It’s helped reduce shipping issues a lot and has saved us from refund headaches.

Would love your feedback if you’ve dealt with similar problems — or ideas on how to improve it. Also curious: How do you handle bad address entries in your store?

Thanks for checking it out 🙌
