Ecommerce ERP Integration: How to Sync Your Store With Your ERP

Ecommerce ERP integration connects your online store to your business system so stock levels, prices, orders, customers and shipping updates move automatically. It removes manual data entry, prevents overselling and gives staff one source of truth. You can use a ready-made connector for common pairings, such as Shopify with NetSuite, or a custom integration when your rules or systems are unusual.

Quick answer: decide which system owns each type of data, start with stock and order sync, choose a connector or custom build based on your rules, and plan how errors are caught and fixed.

What data should sync between your store and ERP?

Data	Usual direction	Why it matters
Stock levels	ERP to store	Prevents overselling
Product data and prices	ERP to store	One place to update catalogue and pricing
Orders	Store to ERP	Fulfilment, invoicing and accounting
Customers and B2B accounts	Both ways	Account-specific pricing and history
Shipping and tracking	ERP or warehouse to store	Customers get tracking updates
Refunds and returns	Both ways	Keeps finance and stock correct

The key rule: each type of data should have one system of record. For example, the ERP owns stock and prices, while the store owns new orders until they are sent to the ERP.

Connector vs custom ERP integration

Option	Best for	Pros	Cons
Native or app connector	Common pairings, standard rules	Faster setup, lower upfront cost	Monthly fees, limited flexibility
Integration platform (iPaaS)	Several systems, moderate complexity	Visual workflows, monitoring	Subscription cost, setup still needed
Custom API integration	Unique rules, B2B pricing, legacy ERPs	Fits your process exactly	Higher build cost, needs maintenance

Common ERPs that connect to Shopify and WooCommerce include NetSuite, Microsoft Dynamics 365, SAP Business One, Odoo and Acumatica. Many have connectors, but check that they support your specific rules before you commit.

How to plan an ecommerce ERP integration

1. List every workflow. Ordering, fulfilment, returns, pricing updates and B2B approvals.
2. Choose a system of record for each data type.
3. Map the fields. Match SKUs, variants, tax codes and customer IDs between systems.
4. Decide timing. Real-time for stock and orders, scheduled for less urgent data.
5. Plan error handling. Decide what happens when a sync fails, who is alerted and how it is retried.
6. Test with real scenarios. Partial shipments, backorders, refunds and price changes.
7. Launch and monitor. Watch sync logs closely for the first weeks.

Common ERP integration problems

• SKU mismatches between store and ERP that stop orders syncing.
• Overselling because stock syncs too slowly during busy periods.
• Duplicate customers when matching rules are unclear.
• Silent failures where syncs stop and nobody notices.
• Tax and currency differences between systems.

How much does ecommerce ERP integration cost?

Ready-made connectors often cost a monthly subscription plus setup. Custom integrations are a one-time build plus support. Our API integration services start at $590 for a standard one-way integration and $1,490 for a two-way sync. Complex ERP projects with B2B pricing and several systems are quoted after a short review. Stores that need a full custom build can start from our Custom Store plans from $4,490.

What the research says: WooCommerce’s REST API lets developers create, read, update and delete orders, products and customers, using API keys over HTTPS, which is the usual route for ERP syncing. (Source: the WooCommerce REST API documentation.)
