App and payment reconnection is making sure everything that plugged into your old store works again on the new one: payment processing, email and lifecycle tools, reviews, shipping, subscriptions, your ERP, and the rest of the stack. When you replatform, those connections do not carry over by themselves. We reconnect each one, test that it actually fires, and replace anything that has a better native option on the new platform.
What we reconnect and check
- Payments and checkout: gateways live, test transactions run, taxes and shipping rates correct before launch.
- Email and lifecycle: Klaviyo flows, lists, and segments reconnected so welcome, abandoned-cart, and post-purchase keep sending.
- Reviews, loyalty, and subscriptions moved over with their data, not started from zero.
- Shipping, fulfillment, and ERP or inventory connections re-linked and verified end to end.
- Analytics, ad pixels, and conversion tracking rewired so your reporting does not go dark on day one.
A migration is a good moment to drop the apps you stopped using and consolidate the overlapping ones. Fewer, better integrations mean a faster store and a smaller monthly bill. Where the new platform does something natively that you were paying an app for, we use the native version.
The honest part: payments and tracking are where a rushed launch hurts most, because a broken checkout or a dead pixel costs real money quietly. We test these the hardest and would rather hold a launch a day than ship a store that cannot take an order cleanly.
This is where we reconnect the app stack: Klaviyo, ReCharge, Discount Ninja, Bloom, and the payment apps (Shopify Payments and Shop Pay), so nothing silently breaks at launch.
