Bad addresses slip through checkout every day. Missing apartment numbers. Misspelled streets. ZIP codes that do not match the city. Each one becomes a package that comes back, a refund you did not expect, or a customer who does not come back either. Carriers charge $24 to correct an address on a shipment already in transit. Most merchants find out about the problem when it is already too late to stop it.
Tacey checks every order the moment Shopify receives it. Not after fulfillment. Not when the package comes back. Before anyone on your team has touched it.
A missing unit number on a real street is different from a street that does not exist at all. Tacey's AI understands that difference. It reads the full address in context and decides accordingly, not by matching a pattern.
Nothing changes at checkout. Nothing changes on your storefront. Tacey works behind the scenes on every order the moment it is placed. Your customers never see it unless their address needs fixing.
I spent 7 years working in customer service and operations for Shopify merchants selling at volume around the world. Live commerce, high-velocity drops, brands shipping thousands of orders a week across multiple countries.
The address problem was everywhere. A customer types fast at checkout. An apartment number goes missing. A street name comes in misspelled. A ZIP code does not match the city. The order goes out. The package comes back. The merchant pays the carrier correction fee, handles the customer complaint, refunds or reshipping, and moves on. Then it happens again tomorrow.
Every time, it was manual. Someone on the support team caught it, or nobody caught it, and the merchant found out when the customer filed a dispute. There was no system. Just people absorbing the cost of a problem that happened before anyone was looking.
Tacey is the system that should have existed. It checks every order the moment it is placed, before anyone on your team sees it, before a label prints. Bad addresses are caught and resolved automatically. You never have to think about it.
I built it because I watched it go unsolved for long enough. Tacey is built and operated by ONDUTYOPS LLC. We build tools for Shopify merchants who care about operations.
