Shopify ERP Integration

ONESTOCKFIGURE,EVERYWHERE

We connect your Shopify store to your ERP so products, prices, stock and orders agree in both, with a written field map, one owner for every record and monitoring that reports failures early.

01Our Approach

An order should be typed once, by the customer, and every system after that should receive it without anyone copying it across.

02Overview

Your store and ERP, kept in agreement

  • 01Written field map
  • 02One stock figure
  • 03Monitored sync

Shopify ERP integration moves products, prices, stock levels, orders, fulfilments and refunds between your store and the system that runs purchasing, warehousing and finance. We build it on Shopify's GraphQL Admin API and webhooks on one side and your ERP's interface on the other, with a service in between that maps, validates and queues every record so nothing is lost when either system is busy.

It suits merchants whose order volume has outgrown manual re-keying, who sell from several warehouses or locations, or whose stock is shared between wholesale and retail channels. Inventory is usually the hardest part. We decide with you which system owns the available quantity, how reservations and safety stock are treated and how quickly a warehouse change must reach the storefront to prevent overselling.

03What We Do

Capabilities, End to End

01
Product and order mapping

Variants, units, tax codes, discounts, shipping lines and customer records are mapped field by field to their ERP equivalents, including the awkward cases such as bundles and gift cards.

02
Record ownership

Each record has one system that may change it. Typically the ERP leads on items, prices and stock while Shopify leads on orders, and the integration enforces that direction.

03
Store access scopes

The integration runs as a custom app on your store with only the Admin API scopes it needs, and as a dedicated ERP user whose permissions are equally narrow.

04
Error queue

A record that fails validation, for example an order with an unknown item code, waits in a visible queue with its reason until someone corrects and releases it.

05
Safe retries

Temporary failures are retried with increasing delays, and every write carries a key that stops the same order or stock movement from being posted twice.

06
Sync monitoring

Dashboards show queue depth, delay between the two systems and failed records, and alerts reach a named person when a threshold is crossed or a webhook stops arriving.

06How It Runs

From Kickoff to Launch

01
Map and decide
02
Build against sandboxes
03
Run in parallel
04
Go live
01
Map and decide

We read both systems, list every field that must travel, agree which side owns each record and write the rules for stock, tax, discounts and refunds before any code exists.

02
Build against sandboxes

The service is developed against a development store and a test copy of the ERP, with realistic orders, partial fulfilments, cancellations and returns replayed until both sides match.

03
Run in parallel

The integration runs beside your current process on live data. Staff compare results, the error queue shows which real cases were missed and the mapping is corrected.

04
Go live

Manual entry stops on an agreed date. We watch queues and delays closely through the first trading peaks, then hand over the runbook, dashboards and alert rules.

08Who It Is For

Built for Teams Like Yours

FLAGSHIP
Your team re-keys orders and stock drifts apart

Orders are copied from the store into the ERP by hand, stock on the site differs from the warehouse and customers sometimes buy what you no longer have. You want one flow that is fast, visible and explains itself when something fails.

Wholesale and retail channels
High order volumes

09Questions

What buyers ask before they start

If yours is not here, ask us directly. The first conversation is free and useful whether or not we work together.

Book a call

On the Shopify side, a custom app installed on your store with the Admin API scopes for products, inventory, orders and fulfilment. Some capabilities depend on your Shopify plan, which we check against Shopify's current documentation during scoping. On the ERP side, a licensed integration user or API subscription, plus a test environment. We list every permission in writing before work starts, so your administrators can approve them.

Often, yes. If a maintained connector exists for your ERP and your processes are standard, it is cheaper and quicker than custom engineering, and we will say so. Custom integration earns its cost when you have unusual pricing, several warehouses, bundles, business rules the connector cannot express or volumes at which its limits hurt. We can also extend a connector instead of replacing it.

As quickly as the ERP can report them. Where the ERP emits events, a change reaches Shopify almost immediately. Where it only offers scheduled exports, we agree an interval that matches how fast your stock really moves and add a safety buffer on scarce items. The delay is measured and displayed, so you know the true figure instead of assuming one.

Nothing is lost. Incoming events are stored in a queue the moment they arrive and are processed when the other system returns, in the right sequence. Shopify limits how fast an app may call it, so after a long outage the backlog drains at a controlled pace. Your team can watch its progress, and alerts tell them if it stalls.

Yes. Inventory integration is part of this service, whether stock is held in the ERP, a warehouse management system or a logistics partner's platform. We map each physical site to a Shopify location, decide how reserved, damaged and incoming stock affect the quantity shown for sale and reconcile both sides on a schedule so that small differences are found before they grow.
