We connect the backbone of your business to Shopify: real-time synchronisation of inventory, pricing, orders and customer data. The hard part isn't the connection — it's deciding which system owns which data. Getting that wrong is the most common reason these projects fail.
Shopify ERP integration connects your store to the system your finance and operations teams run on, so orders, inventory, pricing and fulfilment move between them without anyone retyping. It's built through a connector app, an integration platform, or custom middleware — depending on how standard your processes actually are. Projects start around $20,000.
We specialize in connecting the pillars of your operation with Shopify:
Manages the core of the operation: Stock, Pricing, Orders, Customers, and Accounting. The ERP is the financial source of truth.
Centralizes complex product data. We efficiently sync rich descriptions, images, attributes, and variants to Shopify.
Manages customer relationships. Connection of customer profiles, order history, and after-sales service data for a 360-degree view.
Optimizes fulfillment and logistics. Manages orders from warehouse receipt to final dispatch.
Not sure which of these you actually have? Our guide to ERP vs PIM vs OMS vs WMS vs 3PL sorts out the vocabulary first.
Integrating enterprise systems like an ERP, PIM, CRM, or WMS with an e-commerce platform demands more than just a simple connector—it requires a unified data strategy. The core challenge is preventing these systems from operating in silos, which leads to inaccurate inventory (causing overselling), outdated pricing, customer duplication, and a breakdown in the order fulfillment flow. A mistake in data mapping can paralyze your online operations and lead to significant financial losses.
Every data type needs exactly one owner and one direction of travel. When two systems both believe they own inventory, you get drift — and drift is what people mean when they say their integration "keeps breaking."
| Data | Usually owned by | Flows |
|---|---|---|
| Product records and attributes | PIM, or ERP if no PIM | → Shopify |
| Base prices and cost | ERP | → Shopify |
| Promotional pricing | Shopify | stays put |
| Inventory counts | WMS, or ERP if no WMS | → Shopify |
| Orders | Shopify | → ERP |
| Fulfilment and tracking | WMS or 3PL | → Shopify |
| Customer accounts | Shopify | → CRM/ERP |
| B2B account pricing | ERP | → Shopify B2B catalogs |
| Returns and RMAs | Returns platform | → both |
| Tax codes | ERP or tax engine | → Shopify |
Promotional pricing is the exception worth protecting. Pushing campaign discounts through the ERP means your marketing team files a ticket every time they want to run a sale.
Document this matrix for your own stack before anyone writes code. It takes an afternoon, and it is the highest-leverage hour in the entire project.
| Route | Cost shape | Right when | Breaks when |
|---|---|---|---|
| Connector app | Monthly subscription | Common ERP, standard logic, moderate volume | Your process isn't standard — and it rarely is |
| iPaaS (Celigo and similar) | Platform fee + configuration | Several systems, want visibility, someone owns it internally | Nobody owns it; per-record cost at high volume |
| Custom middleware | Build cost + maintenance | Logic is genuinely specific to you | Nobody funds the maintenance |
Most mid-market brands are best served by a connector or an integration platform for the standard 80%, and custom middleware for the fifth of the logic that's actually theirs. Building everything custom is the most common overspend. Forcing everything through a connector is the most common under-build.
Connecting your ERP ensures bidirectional synchronization of inventory, pricing, and orders, eliminating overselling and manual errors.
Stock levels and base pricing flow from your ERP into Shopify on a schedule matched to your volume. Costing and margin stay in finance where they belong, and Shopify receives them rather than authoring them.
Master product files, rich descriptions, images, attributes and variants publish from your PIM into Shopify without overwriting merchandising work done on the storefront side.
Customer profiles and order history unify across systems so marketing and sales work from accurate records rather than two partial views.
Paid orders transmit to your warehouse system, and tracking numbers and delivery status return to Shopify. For brands with physical retail, this connects to Shopify POS so store and warehouse inventory resolve to one number.
Not everything needs to be real-time, and pretending otherwise is expensive.
Real-time: inventory decrements, order creation, fulfilment status — anything a customer sees or an oversell depends on.
Minutes: price changes, customer record updates, B2B pricing.
Batch, hourly or nightly: product data enrichment, catalogue additions, reporting extracts, financial reconciliation.
Shopify's API rate limits shape this, and Shopify Plus raises them above standard plans. Confirm your current limits against Shopify's developer documentation before designing a high-frequency sync — a design that works at 500 orders a day can fail at 5,000.

From our own projects, in the order we see them:
Every one of these is a design problem, not a code problem. They are prevented in scoping, not fixed in QA.
The parallel run is the step brands try to skip and the one that catches everything. If it isn't in a proposal you're reading, ask why.
Every system inventoried. The source-of-truth matrix agreed and documented. Volumes measured.
Connector, iPaaS or custom, decided per data flow rather than for the whole project.
Field mapping, transformation logic, error handling. Error handling is not optional; a sync that fails silently is worse than no sync.
Against a staging store at production-shaped volumes, including the edge cases: partial shipments, returns, cancellations, multi-currency.
Both systems live, reconciled daily, before anyone turns off the manual process.
Monitoring, with the first month-end close reconciled by hand as a check.
If you're migrating to Shopify, integrations belong inside that project rather than after it — rebuilding them is usually the longest track on a replatform. See Shopify Plus migration services, and Phase 5 of our free 100-point migration checklist covers the sequence.
Integration projects start around $20,000, quoted as line items per data flow so you can drop scope you don't need. Retainers start at 20 hours or $3,000 a month, at $150 an hour. Integrations need ongoing budget, because both platforms ship changes. Full rates and platform fees: Shopify Plus cost.
What moves the number: the number of data flows, whether your ERP's API is documented, volume and sync frequency, how much business logic exists only in someone's head, and whether B2B or multi-location retail is in scope.
It's connecting Shopify to your enterprise resource planning system so orders, inventory, pricing, customers and fulfilment move between them automatically. It's built through a connector app, an integration platform, or custom middleware, depending on how standard your processes are.
Whichever system physically holds the goods — usually your WMS, or your ERP if you have no WMS. Shopify should receive inventory, not author it. When both systems can write to stock levels they overwrite each other, and you get drift.
No. Integrations work across paid plans through Shopify's Admin API. Plus raises API rate limits, which matters at high order volume, and adds capabilities like checkout extensibility — but ERP integration itself isn't Plus-only.
Six to twelve weeks for a typical project. The variables are how many data flows are in scope, whether your ERP's API is well documented, and how much of your business logic is written down before we start.
Use a connector where your process matches what it assumes. Build custom where your logic is genuinely specific to you. Most brands are best served by a mix — a connector or integration platform for the standard majority, and custom middleware for the fifth that's actually theirs.
Inventory drift from having no single source of truth, followed by SKU mapping gaps, partial fulfilments the ERP can't represent, and returns that don't flow back. All four are design problems, prevented in scoping rather than fixed later.
Not all of it. Inventory, orders and fulfilment status should be real-time because customers see them. Product enrichment, reporting and reconciliation are fine as batch jobs, and treating everything as real-time costs money without improving anything.
Yes. We'll audit what the existing connector actually covers first — often it handles 80%, and the remaining 20% is the part causing your problem, which is cheaper to build than replacing the whole thing.
