ERP integration
Shopify and Linnworks, with one stock figure.
Linnworks routes stock and orders. Shopify sells. The integration stops the two from overselling the same unit.
Linnworks is the inventory brain for brands that also sell on marketplaces. Shopify is one channel. If the link is late or wrong, you oversell.
The job is a clear owner for stock, a clear path for the order, and a check when a SKU does not match.
Why this link gets built
Merchants ask for this when Shopify stock and Linnworks stock diverge after a marketplace sale. Or when orders sit in Linnworks and never update the customer in Shopify.
We have connected Linnworks as part of wider Shopify work for brands that sell in more than one place. The published ERP notes cover the same standard.
What usually breaks
SKU mismatches
A SKU that differs by a space or a retired variant will not sync. We reconcile the catalogue before we trust the quantity.
Overselling
Channel stock has to reserve in time. We agree the buffer and what happens when Linnworks is briefly down.
Order status
Dispatch updates need to reach Shopify so the customer email is true. A shipped order that still says unfulfilled creates support tickets.
Timeline and cost
Week 1
SKU reconcile and a decision on which system owns available stock.
Weeks 2 to 4
Orders and stock in a test channel. Dispatch status checked.
Go live
Watch the first marketplace sale and the first Shopify sale on the same SKU.
An ERP integration is usually part of a build or migration in the £20,000 to £35,000 range, plus a monthly retainer so the sync is watched after go live. A single, well documented connector sits lower. Several price lists, warehouses and a custom order flow sit higher.
Checklist
- Reconcile SKUs between Shopify and Linnworks.
- Choose the system that owns available stock.
- Set the buffer that prevents overselling.
- Confirm dispatch updates the Shopify order.
- Test one Shopify order and one marketplace order.
Linnworks questions
Should Linnworks or Shopify own stock?
Linnworks, when it already routes several channels. Shopify then displays the quantity Linnworks says is free.
Does this replace an ERP integration?
No. Linnworks is the inventory and order router. Business Central, Odoo or NetSuite can still be the financial system behind it.
