OrderStream Integration &
Retailer Dropship Automation
OrderStream carries your retailers’ dropship purchase orders. Commercium connects it to your ERP, store, warehouse, shipping and accounting systems, orders in; acknowledgements, shipments, invoices, inventory and branded packing slips out. Onboarding takes 1–2 hours.
Every retailer’s document set configured for you, acknowledgement, invoice or shipment confirmation only.
What Commercium solves for OrderStream suppliers
Commercium connects OrderStream with E-commerce, OMS, ERPs, POS, Shipping & Accounting platforms, enabling seamless product, inventory, order & shipment synchronisation across your commerce platforms.
Dropship compliance done by hand
OrderStream is where the retailer’s expectations live: response windows, document sets, inventory upload policy and branded paperwork. Without an integration, all of it lands on an operations team.
E-commerce platforms
Connecting OrderStream with your ecommerce store lets you run one catalogue and one stock pool across your own storefront and your retailers’ dropship programmes.
ERP systems
Connecting your ERP to OrderStream turns retailer POs into sales orders and lets finance and stock stay the single source of truth.
OMS, WMS & 3PL
Connecting your warehouse or 3PL sends each OrderStream order to the right facility with the retailer’s paperwork attached.
Accounting platforms
Connecting accounting keeps the OrderStream invoice you upload and the invoice in your books identical.
Shipping & carriers
Connecting shipping gets labels, service levels and tracking numbers into the confirmation OrderStream expects.
POS & retail systems
Connecting POS brings in-store stock into the availability you publish, so dropship offers never sell what the shop floor already sold.
Commercium sits between your systems and OrderStream: your data stays where it lives, and each retailer gets exactly the documents it asks for, in the format, on the schedule and through the exchange method that retailer is set up for.
Book a demo with Commercium
Tell us which retailers you supply through OrderStream and which systems run your stock, orders and invoicing. We walk you through the integration on a live call.
Share your OrderStream details
Provide your OrderStream account and exchange credentials, your warehouse or facility IDs, and the document set each retailer requires.
Connect your systems & map
Your integration engineer connects your ERP, store, WMS, shipping and accounting systems, then maps SKUs, warehouses, carriers, taxes and invoice fields per retailer.
Test in the OrderStream sandbox
OrderStream provides a sandbox environment. We run test orders, acknowledgements, shipment confirmations, invoices and packing slips there before anything touches a live retailer.
Go live & monitor
Once you are satisfied with the data sync, we switch the connection live. Onboarding takes 1–2 hours once all the necessary details are provided.

What OrderStream is, and what integrating with it actually means
OrderStream is the dropship platform large retailers use to run their supplier programmes, built by CommerceHub and now part of Rithum. Retailers publish purchase orders into it; suppliers publish inventory, acknowledgements, shipments and invoices back. You connect once, and each retailer becomes a document profile rather than a new project.
Retailer-run dropship programmes
OrderStream is the supplier side of a retailer’s dropship programme. The retailer invites you in, sets the data requirements and performance expectations, and you ship direct to its customers under its brand.
Purchase orders
Consumer orders placed on the retailer’s site arrive as purchase orders carrying ship-to details, service level, expected ship date and line-level quantities and prices.
Order acknowledgement
Many retailers expect an acknowledgement confirming what you can fulfil, accepted, backordered or cancelled lines, inside a defined response window, well before anything ships.
Shipment confirmation
Carrier, service level, tracking number and shipped quantities go back per package or per line. That closes the order and triggers the shopper’s tracking notification from the retailer.
Invoice upload
Some retailer programmes require an invoice document after shipment; others generate it themselves from the shipment. Which one applies is set per retailer, not per supplier.
Inventory feeds & packing slips
Availability is published per warehouse or facility, with a full inventory upload required at least once a day. Retailer-branded packing slips have to travel with the shipment.
Retailer-invited, supplier-operated
The retailer runs its dropship programme on OrderStream and invites you in as a supplier. Your account holds the orders you receive, the availability you publish and the documents you owe back. Commercium sits behind that account and drives all of it from your ERP, store or warehouse data, the same source feeding every retailer you supply.
Who runs programmes on it
OrderStream came out of CommerceHub, which built its business helping large retailers run dropship supplier networks without holding the inventory themselves. Whichever retailer invited you, the integration has the same shape: their document set, their formats, their windows.
Retailer names are shown for identification only. If your programme runs with a retailer not listed here, the integration works the same way, tell us who invited you and we will build the document profile for it.
What we learnt while integrating OrderStream for our users
Working notes from live OrderStream operations, the things that decide whether a dropship programme runs quietly, and how each one became automation inside Commercium.
No two retailers ask for the same documents
This is the single biggest lesson from live OrderStream work. Some retailers need invoice upload and order acknowledgement; others need neither and only want a shipping confirmation. Assuming one document set and discovering the difference on a live order is how programmes start badly. Commercium configures a document profile per retailer, so each one receives exactly what it asks for, and nothing it doesn’t.
A full inventory upload once a day is policy, not a preference
OrderStream policy mandates a full inventory upload once every day. Commercium runs that full file on schedule to keep you compliant, and layers real-time inventory updates on top of it so availability between uploads stays accurate. Compliance and accuracy are two different jobs, and doing only one of them is what causes either policy warnings or oversells.
Supported file formats are CSV, XML & EDI over SFTP
OrderStream exchanges data as CSV, XML and EDI files over SFTP. Which one your programme uses is set by the retailer, so the practical work is mapping your ERP, store or WMS data into the exact file layout that retailer expects, and reading its files back the same way. Commercium handles the transformation, file naming, scheduling, pickup and retries, so the format never becomes your team’s problem.
Test in the sandbox, then go live, onboarding is 1–2 hours
OrderStream provides a sandbox environment, and we use it properly: test orders, acknowledgements, shipment confirmations, invoices and packing slips all run there with your team before a real retailer order is touched. Once all the necessary details are provided, onboarding itself takes 1–2 hours, the elapsed time is credentials and retailer confirmation, not build work.
Packing slips are the hidden operational cost
Retailer-branded slips are normally either downloaded from the portal order by order or built to the retailer’s spec inside a warehouse system. Most tools leave that to you. Commercium generates the slip automatically and routes it with the picklist to the warehouse or 3PL packing the order.
Response windows are shorter than teams expect
Where a retailer requires acknowledgement, the window is measured in hours, not days, and it runs during weekends and holidays. Automating the response against live stock is what keeps a scorecard clean when nobody is at a desk.
Inventory accuracy is the whole relationship
Dropship suppliers are scored on fill rate and cancellations. We publish availability from the systems that actually own stock, ERP, WMS, store or POS, with per-retailer buffers so one shared pool never oversells a programme into cancellations.
Facility IDs and SKU identity decide routing
Orders route cleanly only when warehouse or facility IDs and the identifier the retailer uses, merchant SKU or UPC, line up with your own catalogue. We settle that mapping during onboarding rather than discovering it on a live order.
Partial fulfilment needs a rule, not a decision
Backorders, short ships and split shipments come up constantly. We set the rule once per retailer, accept, backorder or cancel the line, so the warehouse never has to interpret a retailer policy in the moment.
The next retailer should be configuration
Once your OrderStream account is wired into Commercium, adding a retailer is a new document profile over the same source data, their formats, their windows, their slip, not another integration project.
Working notes from our integration team, we update this section as retailer requirements change.
