Sobre este producto
Failed deliveries, fraud, and unprofitable orders almost always start with a bad order being accepted at checkout. Checkout Validation & Address Rules is a build-to-order Shopify app that stops those orders before they're paid for, using Shopify's native Cart and Checkout Validation Function API so your rules run inside Shopify Checkout itself — not as a fragile post-purchase email or a manual cancellation.
ECOSIRE builds the app to your store's exact rules and installs it for you. We wire it into your checkout so it can reject the cart with a clear, custom error message the moment a shopper enters an address you can't profitably or reliably serve. Typical rules we implement: address and phone format validation (per-country patterns), PO-box and delivery-zone blocking, blocklists by email, IP and country, and minimum-order enforcement by subtotal, quantity or weight.
Because it's a Shopify Function running server-side, validation is fast, tamper-resistant, and applies on web, the Shop app, and accelerated checkouts. Where your logic needs live data — fraud-score lookups, third-party address verification, or your own allow/block tables — we back the Function with a hosted service and surface decisions through metafields and the Admin GraphQL API, with the merchant-facing settings exposed in your admin.
This is not an instant App Store download. It is a tailored app written, deployed via Shopify OAuth, and tested against your real checkout. You get the source, documentation, and a support window. Where Shopify's native validation is enough, we'll tell you — we only build what genuinely moves your delivery and fraud numbers.

- Custom error-message copy wired in for every block reason, ready for translation into your store locales
- Configuration of order webhooks and tagging for any edge cases that require manual review
- Technical documentation covering rule logic, configuration, and how to extend or adjust each validation
- Full source code handover plus a defined post-launch support and bug-fix window
¿Para quién es esto?
COD & high-failed-delivery merchants
Stores in markets with cash-on-delivery or high return-to-origin rates that need real address and phone validation to cut failed deliveries and wasted shipping spend before orders are created.
Operations and fulfillment leads
Teams tired of manually cancelling PO-box orders, out-of-zone shipments, and sub-threshold carts. They want rules enforced automatically at checkout instead of caught after the fact in the warehouse.
Fraud-conscious and B2B/wholesale stores
Merchants needing email/IP/country blocklists and minimum-order enforcement — for example wholesale stores requiring a minimum subtotal, or brands repeatedly hit by the same bad actors.

Preguntas frecuentes sobre Checkout Validation & Address Rules
How long does it take to build and install the app?
Most builds ship in roughly one working week depending on rule complexity. A straightforward set (address/phone format, PO-box and zone blocking, a minimum-order rule) is on the faster end; adding a hosted service for live fraud scoring or third-party address verification extends the timeline. After a short scoping call we confirm an exact lead time before any work begins, then deploy via Shopify OAuth and test against your real checkout.
Is this an instant Shopify App Store download?
No. This is a build-to-order custom app. ECOSIRE writes it to your specific rules, installs it into your store over OAuth, and tests it against your live checkout. You are not buying a generic listing — you get a tailored app, its source code, and documentation. There is no public App Store link to install yourself.
What ongoing support and updates do I get after launch?
Every build includes a defined post-launch support and bug-fix window. During that window we fix defects, adjust rule logic, and help you tune blocklists and thresholds against real traffic. Because you receive the full source code, your own developers can also maintain it. Longer-term retainers or change requests (new countries, new rule types, Shopify API version upgrades) are available as a follow-on engagement.
Will the validation work on the Shop app and accelerated checkouts like Shop Pay?
Yes. Because the rules run as a Shopify Cart and Checkout Validation Function — server-side inside Shopify's checkout — they apply consistently across web checkout, the Shop app, and accelerated checkouts, rather than relying on theme JavaScript that express-checkout flows would bypass.
Can the app use live fraud scores or third-party address verification?
Yes, where it's worth it. The Validation Function itself runs on data Shopify provides, but we can back it with a hosted service that calls a fraud-scoring or address-verification provider and feeds decisions in through metafields and the Admin GraphQL API. We'll advise honestly on whether that extra integration is justified for your order volume and risk profile before building it.
Can I edit blocklists and minimum-order amounts myself after launch?
Yes. We expose your editable rules — blocklist entries, blocked zones, and minimum-order thresholds — through an admin settings interface and/or metafields so non-developers can update them without a redeploy. Structural changes (new rule types or new validation logic) are code changes we or your developers handle.
