International expansion means more servers, more contracts, more failure points. ### The stack is fragmented Storefront, OMS, ERP, PIM, payments — each held together by brittle middleware no one wants to own anymore. The 5-Phase Playbook ## From discovery to launch in 12–20 weeks The same sequence we've run on every enterprise replatform — refined on real catalogs, real integrations, and real launch deadlines. 1. 01 2–3 weeks ### Discovery & Audit Map every data entity, integration, and custom feature. Decide what transfers, what gets rebuilt, what gets retired. 2. 02 2–3 weeks ### Architecture & Data Mapping Design the Shopify Plus information architecture: collections, product types, metafields, integration contracts, and migration scripts. 3. 03 6–10 weeks ### Development & Integration Theme or headless build, Checkout Extensibility, payment gateways, ERP/PIM connectors, and Shopify Flow automations. 4. 04 2–3 weeks ### QA & Parallel Run Both stores live side by side. Order flow, data parity, load testing, and 301 redirect validation before a single customer sees the new site. 5. 05 1–2 weeks ### Launch & Hypercare DNS cutover, final sync, monitoring dashboards, and on-call support tracking conversion, speed, and integration health.
