Their stores. A workflow that connects them. Choose the best Shopify order routing approach by the job you need done: finding products, choosing a warehouse or handing orders to existing suppliers. By the FulfillRelay product team · Updated September 11, 2026 **In this guide** ## Our best fit: your existing independent Shopify suppliers FulfillRelay is our best fit for retailers working with existing suppliers who each run an independent Shopify store. Approve exact product mappings, route eligible paid order lines and follow tracking back to the original order. Keep each store independent and each handoff visible. Supplier acceptance, payment evidence and returns coordination stay part of a clear operating process.  Keep orders and supplier routing progress together in your workspace. ## Choose the workflow behind the feature list | Your starting point | The type of solution to look for | What to check | | --- | --- | --- | | You already have Shopify suppliers | Connected-store order routing, such as FulfillRelay | Exact variant mappings, eligible line routing, supplier acceptance and tracking | | You need products or new suppliers | A sourcing catalog or supplier marketplace | Available suppliers, product terms and how orders are fulfilled | | You fulfill from your own locations | Shopify location-routing tools | Location priorities, stock availability and fulfillment rules | | You send orders manually | Email or spreadsheet handoffs | Who verifies items, quantities, shipment updates and exceptions | - [Find suppliers or connect suppliers: choose the right starting point](https://fulfillrelay.com/guides/supplier-marketplace-vs-order-routing) ## Choose the capacity your supplier network needs FulfillRelay retailer subscriptions are based on routed order lines and supplier connections.

Start with one supplier relationship and one approved exact variant mapping. Eligible paid lines can become normal orders in that supplier’s Shopify store, while other lines stay with their own relationships or remain visible for attention. Each business keeps its own Shopify account and responsibilities. Supplier checkout and payment evidence remain distinct from the customer sale. Return coordination records the retailer and supplier stages without treating AI suggestions as approval. Retailer plans start at $49 USD per month; Supplier Connect is free. If you need a supplier marketplace or your supplier does not use Shopify, address that fit question before installing. - [See FulfillRelay’s supplier workflow](https://fulfillrelay.com/shopify-supplier-order-routing) - [Read the multi-supplier operations guide](https://fulfillrelay.com/guides/shopify-multi-supplier-fulfillment) ## What happens to a mixed supplier order? An illustrative order with one item mapped to Supplier A, one mapped to Supplier B and one unmapped item should not be sent whole to both suppliers. FulfillRelay evaluates lines against approved mappings; the unmapped line remains visible for attention. - [Follow the SKU routing example](https://fulfillrelay.com/guides/shopify-sku-order-routing) - [Follow tracking back to the customer order](https://fulfillrelay.com/guides/shopify-supplier-tracking-sync) ## See the real interface and try one complete handoff The walkthrough shows the real FulfillRelay interface with example data. Before expanding your setup, use a test order to follow one approved item through supplier fulfillment and tracking. Check the quantities and agreed supplier price at each step.
