An ERP integration connects your ecommerce platform to the system that runs finance, inventory and purchasing. When it works, stock on the site is right, orders arrive in the ERP ready to fulfil and invoice, and finance closes the month without reconciling exports. When it does not, someone spends their week fixing mismatches.
For brands with $10 million to $350 million in annual revenue that sell through omnichannel direct-to-consumer, B2B and retail, the integration has to cope with several channels drawing on the same stock and more than one price for the same product.
What flows between systems
- Inventory. Available stock by location pushed to each storefront and channel, often enough to prevent overselling.
- Orders. D2C and B2B orders sent to the ERP with taxes, discounts, shipping and payment details mapped correctly.
- Fulfilment and returns. Shipment status and tracking sent back to the platform, with returns and refunds reflected on both sides.
- Customers and pricing. B2B accounts, payment terms, credit limits and price lists kept consistent between ERP and storefront.
- Products. SKUs, costs and core attributes from the ERP, with marketing content managed elsewhere.
Platforms and patterns
We integrate with ERPs and inventory systems including NetSuite, Cin7 and Katana. Depending on volume and complexity, we use a native connector, an integration platform such as Patchworks or Pipe17, or custom middleware. The right choice is the one your team can monitor and support, which is not always the one that installs fastest.
How we run it
We settle data ownership first, deciding which system owns each field and how conflicts are resolved. Then we design each flow, including error handling and retries, and test it against real orders, edge cases and peak volumes before go-live. Partial shipments, split payments, bundles and B2B orders on terms all get tested explicitly, because they are where integrations usually fail.
Every integration ships with monitoring and alerts, so a failed sync reaches the right person with the data needed to fix it. You also get documentation of each flow, written for the finance and operations people who rely on it, not only for developers.
ERP integration is part of our omnichannel and B2B commerce service. It usually follows systems architecture work and often runs alongside order management and fulfilment integration.
