Done right, your stock levels, prices, customer records, and orders are accurate everywhere, all the time. Mejix builds these integrations as well-defined contracts rather than brittle one-off scripts. We map every entity that crosses the boundary, define a source of truth per field, and choose the right transport per workflow — webhooks for real-time events, scheduled syncs for bulk reconciliations, and middleware where business logic must live independently of either system. We've delivered integrations across 12+ countries, including a 50,000-SKU furniture retailer running Shopify Plus alongside Sales Layer PIM and a custom payment gateway. The same patterns work whether you're a B2B brand bridging Salesforce and Shopify Plus, or a fashion label pushing inventory between NetSuite and the storefront. What's included ## Concrete deliverables Every engagement ships a defined scope. No vague promises — these are the artifacts and outcomes you can expect. ### Entity & contract mapping A documented map of every field crossing the boundary, the source of truth, transformation rules, and conflict resolution. ### Real-time event sync Webhooks for inventory, orders, fulfilment, and customer changes — with retry, dead-letter, and observability built in. ### Bulk and scheduled syncs Nightly reconciliations for catalog, pricing, and customer data so drift never accumulates between systems. ### PIM integration Sales Layer, Akeneo, or custom PIM connected to Shopify Plus with metafield-driven product attributes and media. ### Middleware where it earns it Lightweight middleware (TypeScript on serverless or a managed iPaaS) only where business logic genuinely belongs outside both systems. ### Observability & runbook Dashboards, alerts, and a written runbook so your operations team knows exactly what to do when something fails. How it works ## A predictable delivery process The same sequence we run on every engagement, refined across enterprise Shopify Plus projects. 1. 01 ### Discovery & boundary mapping Workshops with operations, finance, and engineering to define entities, source-of-truth rules, and SLAs per workflow. 2. 02 ### Architecture & contracts Document the integration contract, choose transports, and design failure modes before any code is written. 3. 03 ### Build, test & dry run Implement in a staging environment, run a 1–2 week dry run against synthetic and replayed real events. 4. 04 ### Cutover & operate Controlled cutover, observability dashboards live from day one, and a defined hand-off to your in-house team or our retainer.
