Shopify integrations — connect your store to the systems you already run.
We connect Shopify to your ERP, accounting, inventory, CRM and shipping systems — custom apps, Admin API work and the sync logic that keeps stock and orders honest on both sides. A one-way connector is two to three weeks; a two-way ERP sync is six to ten. Scoped first, then quoted fixed.
What we connect, and which ones you can do yourself
Five categories. For two of them the honest answer is often an app from the App Store, and we would rather tell you that than sell you a project.
ERP
NetSuite · SAP Business One · Odoo · Zoho
Almost always custom. The API is rarely the hard part — your rules are. Which system owns stock, what happens to an order placed while a sync is mid-flight, and how a partial fulfilment is represented on both sides.
Accounting
QuickBooks · Xero · Tally · Zoho Books
Often an app you can install yourself, and if that is your situation we will say so. It stops being enough with multi-currency, unusual tax treatment, or invoices that have to carry fields the connector does not know about.
Inventory and warehouse
Zoho Inventory · Unicommerce · in-house systems
The classic breakage point. Multi-location stock, bundles, kits and reservations are where off-the-shelf sync stops matching reality and starts overselling.
CRM
HubSpot · Salesforce · Zoho CRM
Usually straightforward for contacts and orders, and genuinely custom the moment you want a customer's lifetime behaviour on one record with attribution attached.
Shipping and 3PL
Shiprocket · Delhivery · ShipStation · carrier APIs
Rates at checkout, label generation, and tracking that reaches the customer. Mostly solved by apps; custom when you split shipments across warehouses.
App or custom build?
If the App Store connector does what you need, use it and keep your money. That is the whole section, and most agencies will not write it.
Use the app when
You have one location, SKUs that map one-to-one, standard tax, and order volume in the hundreds a month. That covers a large share of stores, and an official connector will do it for a small monthly fee with somebody else maintaining it. Paying an agency for that is paying for a worse version of a solved problem.
Build it when
Stock lives in more than one place. Bundles, kits or made-up SKUs mean the mapping is not one-to-one. Your invoices need fields the connector has never heard of. Or you are past a few thousand orders a month and hourly batching is no longer accurate enough to run a business on. At that point the connector is not cheap — it is quietly wrong.
How we build one
Specific enough that you can check whether whoever you hire is doing it — including if that is not us.
- Admin API and GraphQL
- The current API surface rather than a deprecated one, with the query cost budget respected so a busy hour does not throttle you into a backlog.
- A custom app, not a theme hack
- Integrations live in an app with its own credentials and scopes. Nothing is bolted into the theme where the next theme update removes it.
- Webhooks with idempotency
- Shopify will deliver the same webhook twice. Handlers are written so that processing it twice is harmless, because eventually it will happen.
- Retries and a dead-letter path
- Every failed call retries with backoff, and anything that keeps failing lands somewhere a human sees rather than disappearing into a log.
- A staging store first
- Built and run against a development store with your real data shape, so the first time it sees a real order is not in production.
- Reconciliation reporting
- A scheduled comparison of both sides that tells you when they have drifted. Every long-running integration drifts; the ones that survive are the ones that report it.
What it costs
Quoted from the scope, because the price is driven by your rules rather than by which systems are involved. As an anchor: a one-way feed is a small project; a two-way stock and order sync with an ERP is often the largest single line in a store build and can approach the ₹2,50,000 / $6,500 that a whole store build starts at.
Terms are the same as any project: 50% / 40% / 10%, scope fixed at the proposal. Every price we charge.
Keeping it running
An integration is not a project you finish. Shopify retires API versions on a schedule and your other vendor will ship changes with less notice than that, so something has to own it.
Ours sit on a store care plan — version upgrades applied before a deprecation bites, the reconciliation report actually read, and failures investigated by us rather than reported to you by a customer.
Integration questions, answered
Can Shopify connect to QuickBooks or Xero without a developer?
Usually yes, and you should try that first. Both have official connectors in the Shopify App Store that handle orders, payouts and refunds for a straightforward store, and they cost a fraction of any custom work. If it does what you need, use it and keep your money. Come back when it does not.
When does an off-the-shelf connector stop being enough?
Four situations, and they are predictable. Stock held across multiple locations or warehouses. SKUs and bundles that do not map one-to-one between systems. Tax or invoicing rules the connector has no field for. And volume — past a few thousand orders a month, a connector that batches once an hour stops being accurate enough to run on. Any of those and you are looking at custom work.
What does a Shopify ERP integration cost?
It is quoted from the scope, because the price is driven entirely by your rules rather than by the systems involved. As an anchor: a one-way feed into an accounting or reporting system is a small piece of work, while a two-way stock and order sync with an ERP is frequently the largest single line in a store project — it can approach the ₹2,50,000 / $6,500 that a whole store build starts at. We scope it properly before quoting, and the quote is fixed.
How long does it take?
A single-direction connector is typically two to three weeks including testing. A two-way sync is six to ten, and most of that is not code — it is agreeing what happens in the awkward cases, then proving it against real data on a staging store.
What happens when the API changes?
It will. Shopify versions its API and retires old versions on a schedule, and your ERP vendor will ship changes with less warning than that. An integration is not a project you finish; it is something that needs an owner. That is why integrations we build sit on a care plan — the alternative is finding out from a customer that stock has been wrong for a fortnight.
Can you take over an integration someone else built?
Yes. We start by reading it and telling you honestly what state it is in, what it would cost to stabilise, and whether replacing it is cheaper than repairing it. Sometimes the answer is that it is fine and the problem is elsewhere, and we will say that too.
