How do I connect my 3PL to Shopify and my accounts?
A point-to-point link from your 3PL straight into Shopify solves stock and stops there. Fulfilment status, dispatch-triggered invoicing and true COGS all need the same data too, which means the integration belongs in the middle, feeding every system, not bolted onto just one of them.
Why "just connect the 3PL to Shopify" is not enough
Your 3PL and Shopify were never designed to talk
Most 3PLs expose a feed or a portal, not a live two-way connection into Shopify. Someone still has to move information between the two, manually or half-automatically.
Stock is only half the problem
Fulfilment status, tracking numbers and dispatch confirmations need to flow back too, or customer service is chasing the 3PL by email every time someone asks where their order is.
Your accounts need to know what shipped, not just what sold
Revenue recognition, COGS and despatch-triggered invoicing all depend on knowing the moment goods actually left the 3PL, not just the moment the order was placed.
A point-to-point integration breaks every time something changes
Wire Shopify straight to the 3PL and every new channel, carrier or accounting change means touching that connection again, because there is no system sitting in the middle.
3PL to Odoo to everywhere, in both directions.
Stock, dispatch confirmations and tracking flow from the 3PL into one owned system, which pushes the right updates out to Shopify, marketplaces and your accounts automatically. Add a channel or switch a carrier later and you extend one integration point, not rebuild several direct links from scratch.
Odoo sits between your 3PL, Shopify and your accounts
We build the integration hub on Odoo, the open-source commerce ERP, taking stock and fulfilment updates from your 3PL and pushing them out through our own Shopify connector and into your accounting, so despatch, invoicing and true cost of goods are all triggered from the same real event, not three separate manual steps.
This is the fulfilment side of the build we delivered for Gandys, a UK lifestyle brand where automated 3PL stock sync fed three Shopify stores at once. If the daily mismatch is what is actually costing you time right now, start with why your stock is wrong since moving to a 3PL.
