Integrate WooCommerce with your ERP

A guide for WooCommerce store owners who want to automate orders, inventory, and invoicing by connecting their store to an ERP system.

Why connect WooCommerce to an ERP?

WooCommerce gives you a flexible, self-hosted ecommerce store built on WordPress. But like all ecommerce platforms, once orders start flowing, you need a back-office system to handle invoicing, inventory, and financial reporting. Most WooCommerce merchants start by managing this manually — exporting orders, entering them into the ERP, updating stock in spreadsheets. It works at low volumes but breaks down as the business grows.

Connecting WooCommerce to an ERP automates the data flow between your store and your financial system. Orders arrive in the ERP automatically. Inventory stays in sync. Invoices and credit invoices are generated without manual entry. Payment reconciliation happens on its own.

The payoff is straightforward: fewer hours spent on manual data entry, fewer errors in financial records, and inventory that reflects reality.

What data flows between WooCommerce and an ERP?

A WooCommerce–ERP integration typically covers these data flows:

Orders → ERP. Each WooCommerce order is created as a sales order or invoice in the ERP. Line items, discounts, tax amounts, shipping, and customer information are mapped to the correct accounts.

Inventory ← ERP. The ERP is typically the stock master. Inventory levels flow from the ERP to WooCommerce so customers see accurate availability. This is especially important if you also sell through other channels or in a physical store.

Refunds → ERP. When a refund is processed in WooCommerce, a credit invoice is created in the ERP and linked to the original order.

Products ↔ Both. Article data — names, SKUs, prices, stock levels — can sync in either direction. Many merchants manage product master data in the ERP and push updates to WooCommerce.

Customers ↔ Both. Customer records sync between the systems to prevent duplicates and keep addresses and contact details consistent.

WooCommerce can also retrieve stock data directly, which means bidirectional inventory checks are possible depending on your ERP setup.

Which ERP systems integrate with WooCommerce?

How the integration works

Junipeer connects WooCommerce and your ERP through a hosted integration platform — no custom development or WordPress plugin conflicts to worry about. The process:

1. Connect both systems. Log into Junipeer and connect your WooCommerce store using its REST API credentials (consumer key and secret, generated in WooCommerce settings). Then connect your ERP.

2. Choose your flows. Select which data should sync: orders, inventory, customers, refunds. Each flow is independent — you can start with orders only and add inventory later.

3. Configure data mapping. Map WooCommerce data to your ERP structure: tax rates to tax codes, payment methods to account numbers, shipping methods to the correct cost accounts. This is the step that requires the most thought.

4. Test with real orders. Place test orders and verify that they arrive correctly in the ERP — right amounts, right accounts, right tax treatment.

5. Go live and monitor. Activate production syncing and watch the first batch of real orders flow through. Junipeer shows sync logs and sends alerts if something needs attention. Failed syncs are retried automatically.

The connection setup takes about 15 minutes. Total configuration time depends on your ERP complexity — a standard Fortnox setup is typically straightforward, while Business Central with multiple entities and currencies takes more planning.

WooCommerce-specific considerations

Plugin compatibility. WooCommerce’s plugin ecosystem is its strength and its complexity. Subscription plugins (like WooCommerce Subscriptions), custom checkout fields, and tax plugins can all affect order data. Make sure the integration accounts for any non-standard order structures your plugins create.

Self-hosted responsibility. Unlike hosted platforms, WooCommerce runs on your own server. This means your API needs to be accessible and your SSL certificate valid for the integration to work reliably. Most modern WooCommerce hosts handle this automatically, but it’s worth verifying.

REST API versions. WooCommerce exposes its data through a REST API. Junipeer uses the latest stable API version. Make sure your WooCommerce installation is reasonably up to date.

Multiple storefronts. If you run multiple WooCommerce stores (for different markets or brands), each can be connected to the same ERP. This is common for businesses that operate separate .se and .no stores pointing to a single Fortnox or Visma instance.

Tax handling. WooCommerce calculates tax based on your store’s tax configuration. For EU sellers using OSS, you’ll need country-specific tax rates in WooCommerce that map to corresponding accounts in the ERP. Get this right before going live.

Payment gateways. WooCommerce supports dozens of payment gateways. If you use Klarna, Stripe, or Adyen, the payout reconciliation flow can match settlements against invoices. For less common gateways, orders still sync — but payout matching may require manual steps.

Variable and grouped products. WooCommerce supports variable products (sizes, colors) and grouped products. Make sure your ERP article structure handles these correctly — typically each variation maps to a separate SKU in the ERP.

Frequently asked questions

Which ERP systems can I connect to WooCommerce?

Junipeer supports connecting WooCommerce with Fortnox, Visma.net, Business Central, Brightpearl, SAP, 24SevenOffice, Specter, and more. See junipeer.io/integrations for the full list.

What data syncs between WooCommerce and an ERP?

Typically: orders, invoices, credit invoices, inventory levels, products, and customers. The exact flows depend on which ERP you use.

Do I need to install a WordPress plugin?

No. Junipeer connects to WooCommerce through its built-in REST API. No plugin installation required — you generate API credentials in WooCommerce settings and enter them in Junipeer.

How long does it take to set up a WooCommerce ERP integration?

The connection takes about 15 minutes. Total setup time depends on your ERP mapping — a standard Fortnox configuration is usually quick, while more complex ERP setups take longer.

Do WooCommerce plugins affect the integration?

Most standard plugins work fine. Plugins that modify order data (custom checkout fields, subscription plugins, tax plugins) may require adjustments to the data mapping. Check during the testing phase.

Can I connect multiple WooCommerce stores to one ERP?

Yes. Each WooCommerce store connects independently, so you can point multiple stores at the same ERP instance.

What happens if my WooCommerce site goes offline?

Orders placed while the site was down won’t exist yet. Once the site is back, any pending syncs are processed automatically. Junipeer retries failed syncs and alerts you to issues.
