What our Shopify integration services cover

Shopify integration services tie the rest of your operation into your store: ERP, PIM, CRM, 3PL, payments, search, marketing, and analytics. scandiweb connects the common systems from its pre-built Shopify connector directory and writes custom API work where no connector fits.

‍

ERP integration

Orders, stock, customers, and pricing synced both ways between Shopify and your ERP, with the field mapping agreed up front.

3PL and fulfillment

A Shopify 3PL integration sends orders out, then returns tracking and stock, staying accurate through seasonal spikes.

Marketing automation

Email and marketing platforms connected for transactional sends, flows, and audience sync built on clean Shopify data.

PIM integration

Product data flowing from PIM to store on schedule, plus PIM implementation services when the data model is part of the project.

Payments and accounting

Klarna and other payment providers, plus Shopify accounting integration work that ends spreadsheet reconciliation for finance.

Analytics and BI

Order and behavior data delivered into Tableau and other BI tools, so reporting and forecasts run on live store numbers.

CRM integration

A Shopify CRM integration syncs customer, order, and loyalty data into CRMs like Voyado, so your teams work from one record.

Search and merchandising

Fast Simon and similar search tools fed from your live catalog, with filters and stock states that stay correct as data changes.

Custom API and middleware

Custom Shopify integration work through APIs and webhooks, plus custom middleware development where nothing pre-built exists.

ERP integration that runs without developer input

A Shopify ERP integration syncs orders, inventory, customers, and pricing between your store and systems such as SAP, NetSuite, or Acumatica. Done properly, the ERP stays the system of record while the store trades on top of it, and nobody re-enters order data by hand again.

How a Shopify integration project runs

A Shopify integration runs in five stages: discovery and systems audit, integration architecture, build and connect, volume testing, and launch with monitoring. scandiweb scopes the work through OSLO, our structured discovery approach, so cost and timeline are agreed before the build begins.

Discovery and systems audit

OSLO discovery covers your systems, data owners, flows, and peak volumes, so the unknowns that break integration projects surface in week one.

Integration architecture

We design the sync: direction per field, conflict rules, retry behavior, and load. You sign off the design before any code is written.

Build and connect

We build your Shopify storefront and migrate catalog, customers, and order history into staging, with integrations re-connected and tested.

Test at production volume

We replay realistic order, stock, and catalog volumes through the integration, including failure and retry cases, so peak-season load holds before anyone depends on it.

Launch and monitor

The sync goes live with alerts on every flow. We watch the first weeks closely and fix what real order flow turns up before handover.

Why choose scandiweb as your Shopify integration partner

Choosing a Shopify integration agency comes down to proof: which systems it has run in production, and who answers when a sync breaks. The work hands an agency access to your ERP and customer data, so vet the security practice as hard as the engineering.

Senior engineering bench

600+ employees across 45 countries, including Shopify integration experts who have connected ERP and fulfillment systems at enterprise order volume.

One accountable project lead

Your Delivery Manager runs the plan and answers for the result across every scandiweb team involved, so nothing sits between vendors waiting for an owner.

Connectors before custom code

When a connector already exists for your system, you skip most of the build cost, and engineering goes only into the connections unique to you.

Certified security practice

ISO 27001 and 27017 certified controls apply to every integration project, covering both the access we hold and the environments the work runs in.

22+ years in eCommerce

eCommerce integration projects going back two decades mean the failure that would surprise a first-time integrator has usually come up here before.

Monitoring after launch

The connection stays watched under Shopify support and maintenance, and a failing flow raises an alert with our engineers, often before your team notices.

Check your fit before you book

scandiweb's Shopify integration services fit businesses whose store depends on other systems: an ERP that owns inventory, a PIM that owns product data, a 3PL that ships orders. If nothing outside Shopify holds your product, stock, or order data, an integration partner is not your next step yet.

Book a scoping call

This is for you if

Your store depends on an ERP, PIM, or CRM that owns part of your data

Your team re-keys orders, stock, or product data between systems

You oversell or missync inventory during peak periods

You are moving to Shopify Plus and the current connectors will not survive the move

You had an integration project stall and nobody owns the result

Not the right fit if

Your store runs standalone with no back-office systems to connect

An off-the-shelf app already handles the one connection your store uses

You are shopping for a one-off theme or design task

You want to replatform first – that is a Shopify migration services conversation

You have no engineering or operations contact who can grant system access

What a Shopify integration project looks like

Most integration budgets fail on open-ended middleware hours. scandiweb prices Shopify integration work as three fixed shapes, each with a set price agreed at the end of discovery, so the budget holds through the build.

Pre-built connector deployment

A tested connector from the directory, configured to your accounts and data model, and typically live within days.

Custom API integration

A Shopify API integration connecting one system to your store, run as a single project with its own budget and delivery date.

Integration program

Several systems connected in sequence, plus monitoring and support, for teams replacing manual work across the operation.

Frequently asked questions about Shopify integration services

What do Shopify integration services include?

Shopify integration services include four kinds of work: scoping the data flows between your store and each system, building the connector or the custom API code, testing at production volume, and monitoring the live sync. That holds whether the system is an ERP, a 3PL, or a marketing platform, and one scandiweb team is responsible for the whole project.

How do you decide between an app and custom integration work?

Three checks during scoping decide it: how far your field mapping strays from standard, which direction data flows, and the volume the sync has to survive at peak. An app covers standard mappings at moderate volume. Custom work takes over when an ERP or PIM owns the data model or when peak volume would exceed an app's rate limits. The scoping call tells you which side your systems land on.

How long does a Shopify integration take?

Days for a pre-built connector, weeks for custom work. A connector from our directory of 180+ Shopify integrations goes live in days once scoping confirms the fit. A custom ERP or 3PL sync with field mapping and volume testing is measured in weeks, with a firm date set at the end of the scoping call.

Who maintains the integration after launch?

scandiweb does, if you want us to. Monitoring continues under a Shopify support and maintenance plan, and our support team handles version updates, API changes, and new field mappings. Full documentation comes with handover, so you can bring the work in-house or switch your Shopify integration company at any point.

Can you integrate Shopify with our ERP?

Yes. For the fashion brand Hope we connected Microsoft Dynamics NAV to Shopify Plus through a codeunit, and for J.R. Dunn Jewelers we unified five vendor data feeds into one custom diamond app. If your ERP has an API we map it to Shopify, and if it does not, we build the middleware.

Do you handle Shopify Plus integration services?

Yes, as a Shopify Plus Partner. Integration work on Plus uses the Plus-only toolset: Shopify Flow, Launchpad, Multipass, and Scripts, and it reaches the checkout layer that standard Shopify keeps closed. Every Plus project we scope includes testing at the order volumes Plus stores run.

How much do Shopify integration services cost?

scandiweb prices integration work from a fixed scope agreed during discovery, so you know the cost before the build starts. Pre-built connector deployments sit at the low end. Custom ERP, PIM, or middleware work is priced by the systems involved and the data volume. Ongoing monitoring runs as a support plan you can size up or down.

Is our data safe during a Shopify integration project?

Yes. scandiweb is ISO 27001 and ISO 27017 certified for information and cloud security. Integration work runs through access-controlled environments with credentials scoped to the systems involved. Customer, order, and product data stay inside your infrastructure and Shopify, and we document every data flow we build.
