How do I integrate Shopify Plus with an ERP?

Treat the integration as a contract, not a script. The order of these steps determines whether you end up with a system that scales or a fragile pipeline.

How do I keep inventory accurate across Shopify Plus and an ERP?

Designate one system as the source of truth for stock, push changes via webhooks for real-time accuracy, and add a nightly reconciliation job that catches drift before it shows up on a customer's screen.

How do I sync customers between Shopify Plus and Salesforce / HubSpot?

Map customer fields explicitly, pick a source of truth per field, sync on order events plus profile updates, and treat email change conflicts as a manual review queue rather than auto-resolving them.

How do I integrate a PIM like Sales Layer with Shopify Plus?

Model product attributes as metafields and metaobjects in Shopify Plus, push from the PIM via the Admin API on publish events, and reconcile nightly. Media assets ride alongside the data, not as a separate manual step.

Do you build integrations from scratch or use iPaaS tools?

Both. Lightweight code-first integrations on serverless where the logic is well-defined; managed iPaaS (e.g. Celigo, Workato) when your team prefers a low-code operating model.

Which ERP and CRM systems have you worked with?

Sales Layer (PIM), NetSuite, SAP, Microsoft Dynamics, Salesforce, and HubSpot — plus custom in-house systems on a project-by-project basis.

How long does an integration project take?

Typical engagements run 6–14 weeks, depending on the number of entities, the complexity of business logic, and how messy the source data is.

What happens when the integration fails at 2am?

Every workflow has retries, a dead-letter store, and an alert. The runbook tells your on-call who to call and how to replay failed messages once the upstream is back.

Do you maintain the integration after launch?

Most clients keep us on a retainer for integration ownership. We can also hand over to your in-house team with documentation and pairing sessions.

What it is

About this Shopify Plus service

ERP, CRM, and PIM integration is the work of making Shopify Plus speak fluently with the systems that already run your business — your enterprise resource planner (SAP, NetSuite, Microsoft Dynamics), your CRM (Salesforce, HubSpot), your product information manager (Sales Layer, Akeneo), and any custom systems in between. 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.

01

Discovery & boundary mapping

Workshops with operations, finance, and engineering to define entities, source-of-truth rules, and SLAs per workflow.
02

Architecture & contracts

Document the integration contract, choose transports, and design failure modes before any code is written.
03

Build, test & dry run

Implement in a staging environment, run a 1–2 week dry run against synthetic and replayed real events.
04

Cutover & operate

Controlled cutover, observability dashboards live from day one, and a defined hand-off to your in-house team or our retainer.
