Shopify ERP Integration, Rules Written Down, Runs Logged
Shopify ERP integration ties your store to the system that runs your business: orders pushed to the ERP, stock and prices pulled back, customers matched and invoices linked. Guides advise the ERP as the owner of inventory, real-time sync for orders, batching for prices and catalogue, and middleware for queues and retries. NetSuite, Business Central, SAP and Odoo each have different connector options. We choose the pattern, build and test it, from $290.
- Source of truth decided per data type: stock, price, customer, order
- Real-time for orders, batched for prices and catalogue
- Connector or middleware chosen for your ERP
- Test log and a recorded handover

Launched 450+ Shopify Stores Since 2015. Now We Automate the Work Behind Them.
A store is only as efficient as the work behind it. Our automation work comes from years spent in Shopify, so we know what a clean order looks like.

Included in every package, so the result matches what you pictured.
Backup before changes
We work on a duplicate of your theme, never on your live store.
Who Our Shopify ERP Integration Service Is For
ERP projects start with the system you have. Custom and legacy systems with no connector need a direct build through their own API, database or file exports, usually behind middleware. These are the cases we meet.
- Your orders come through Shopify
- You know roughly how the task runs today
- You would rather pay once than by the hour
- You can review a test run with us
Companies on NetSuite
A native connector exists and is often paired with an iPaaS such as Celigo or Patchworks.
Companies on Business Central
Microsoft's first-party connector covers orders, stock and customers, per one guide.
Companies on SAP Business One, Odoo or a custom legacy system
SAP has no first-party connector and Odoo uses connector modules. A custom or legacy system is reached through its API, database or file export behind middleware. We choose the route.
Teams with overselling between syncs
Order validation catches stock gaps between inventory pulls.
Teams with slow polling
Polling every 15 minutes is a common cadence. Event-driven designs are faster.
Finance and operations leads
Each field has one owner, written down.
Why Shopify ERP integration Projects Go Wrong, and How We Prevent It
ERP sync problems are usually ownership problems. These are the six faults we fix.
Two systems both edit stock
We name an owner.
Orders posted twice
We key on order number.
Stale inventory
We use events and validation.
Prices out of step
We batch and compare.
API limits hit
We batch and retry.
No error owner
We assign.

All automations follow the same path. An event arrives, the rules decide what applies, the action runs and the result is logged where your operations team can see it. This map shows the pieces we build and test before handover.
Our Store Work Behind Your Automation

Outdoor camping gearFrom First Call to Live Workflow: Our Shopify ERP Integration Process
A fixed order of work keeps the project predictable. You know what happens next at every point.
- 1
Brief and rules
We ask how custom ERP and legacy systems works today, who does what and where it goes wrong. Together we write each rule in plain words: when an order is paid, then send the order in the format the system expects.
- 2
Access and platform
Access is narrow and approved by you. We suggest a platform, state what it costs each month and prove the connection with a live read.
- 3
Map the data
The data map covers item code, customer account, warehouse and price list; formats are checked on both sides and blank values are given a rule.
- 4
Build in a copy
The workflow is built against test data, never your live orders. You see the plan and, where useful, a recorded run.
- 5
Test on real cases
The tests cover a normal order, a backorder and a partial shipment, along with refunds and edits, and each result is checked against Shopify.
- 6
Go live and hand over
When you say go, the workflow goes live. We watch the first runs and leave you notes, a diagram and a recorded walkthrough.
Do It by Hand, Use an App, Build It Yourself or Hire Us for Shopify ERP Integration?
There are four common ways to handle custom ERP and legacy systems. This table compares the checks that decide whether the work stays right, whether failures are noticed and whether you can hand it on.
| What matters | By hand | Built-in app | No-code platform | Store Design Expert |
|---|---|---|---|---|
| Every rule agreed in writing | No | Not often | If you write them | Yes |
| Awkward cases checked | By luck | Seldom | If you test it | Yes |
| Retries cannot repeat actions | Prone to slips | Varies | If you add it | Yes |
| Failures alert a named person | No | Occasionally | Only if you add it | Yes |
| Fixed price up front | Your team's time | Just plan fees | Plan fees and your time | Yes |
| Notes and a recorded walkthrough | No | No | No | Yes |
| Accounts owned by you | Yes | Yes | Yes | Yes |
| Support after launch | No | Vendor support | Help desk of the platform | Included for a period |
Six Safeguards Built Into Every Automation
None of these costs extra. They are simply how we work.
Failures raise a flag
A named person receives an alert, with the order and the reason, whenever a run fails.
Counts compared, not assumed
Once past orders are processed, we count both sides, so missing or doubled records show up early.
Nothing sent without approval
No message to a customer goes live until you have read and approved it.
Plain scope, two revision rounds
Price first, then two structured revision rounds for anything in scope, so no tweak becomes a surprise charge.
Narrow access, in your name
We ask for the least access that works, and every account stays under your ownership.
Secrets kept in a vault
A secure vault holds every key and token; none appear in notes or chat.
Price Your Shopify ERP Integration
Pick a package, answer three short questions and add any extras. Your total and delivery window update as you click, with nothing hidden until checkout.

Why Owners Choose Our Shopify ERP Integration Over Doing It Alone
Templates cover the happy path. We cover the rest, and we put the result in writing.
Notes a colleague can follow
Our handover records what happens when, and which settings were chosen, so a future developer will not have to guess.
We live inside Shopify
We work with Shopify orders, refunds, edits and metafields daily. That depth is separate from knowing an automation tool's interface.
Tested on your real cases
We test the cases your store actually has, such as a normal order, a backorder and a partial shipment.
Experience since 2015
Over 450 Shopify stores since 2015 mean we have seen most of the odd cases that break automations.
Safety designed in
Retries, alerts, unique keys and limited access come as standard in every build.
A direct line to the builder
Ask the person who built it. Questions about rules or fields get a direct reply.
What to Prepare Before We Start Your Custom ERP and Legacy Systems Automation
The list is short. Most owners have everything ready in a day.
Approve a collaborator request
Already selling? Send the store address and accept the request we raise. You stay the owner, we see only what the role permits, and you can remove us at any time.
Starting from nothing? We build first
No store yet? We build it in our Partner account, set up the workflow there and transfer the whole store to you, so you choose a plan only at the end.
Or share a staff login
Sharing a staff login is possible. The collaborator route is safer, though: one click removes it and no password is passed around.
Access to the other tools
Add us to the tools the workflow uses, or have us create accounts under your email. You stay the owner in both cases.
Examples of the work today
Send two or three recent cases, or tell us where to find them. Real examples show how the process actually runs.
A decision-maker
Who signs off the rules and the test? And when two rules disagree, which wins? Those two answers are all we need.
Your Shopify owner password and card details never reach us. Changes are made in a copy, and we note every setting we touch.
