Built to order
Marketplace volume on eBay rarely breaks at the marketplace. It breaks at the seam. An order exists in one system and has to become a real document in another: a sales order in the correct legal entity, a reservation against the correct site and warehouse, a packing slip, an invoice, sometimes a return, always a fee and a payout that finance has to tie back to a bank statement. Most teams running Dynamics 365 Finance and Supply Chain Management close that seam with a CSV export, a shared mailbox and somebody re-keying. It holds until it does not — until an oversell, a missed return window, a listing still live three days after the last unit shipped, or a monthly payout nobody can reconcile line by line.
The gap is structural rather than accidental. F&O has a strong order-to-cash and warehouse spine. eBay publishes a complete set of Sell APIs. Very little joins the two in a way a finance team can audit and an internal IT team can own. That is what ECOSIRE builds for you, to order.
This is not a shrink-wrapped download. We build an eBay integration shaped around your product model, your legal entity structure and your warehouse setup, and we hand you the code.
Released products in F&O become eBay inventory items and offers through the Sell Inventory API. Mapping is explicit: which item groups publish, which product dimensions become variations, which category and item specifics apply, which site and marketplace each legal entity sells on. Product descriptions, attributes and images can be sourced from the product master or from a dedicated marketplace attribute set so merchandising copy never contaminates your ERP master data.
Orders arrive from the Sell Fulfillment API, either on a batch framework schedule or driven by an eBay event notification endpoint, and land as SalesTable and SalesLine records. Order type, customer, site, warehouse, mode of delivery, delivery terms and charges all default from configuration you control. Buyer identity is handled by a strategy you choose during scoping: a single marketplace customer account with buyer detail on the header, a per-buyer CustTable record, or one-time customers. Marketplace orders carry their own number sequence so they are traceable without colliding with your existing numbering, and they carry the financial dimension values your reporting needs from day one.
Quantity published to eBay is derived from on-hand and reservation data rather than a nightly snapshot of a spreadsheet. Availability is filtered to the warehouses that actually serve the channel, respects reservations and can carry a buffer per item, item group or warehouse. When stock moves in F&O, the batch job pushes the change back out on the cadence you set.
Posting the packing slip is the trigger. The connector pushes shipment confirmation, carrier and tracking number back to eBay so the buyer sees movement without an operator touching a browser. Where you run the Warehouse Management module, the integration works from the shipment and load records the warehouse already produces rather than a parallel process.
eBay return requests become F&O return orders with RMA numbers, disposition codes and arrival handling. Credit notes and refunds follow your existing return policy configuration instead of an isolated marketplace workflow, so the same approval and posting rules apply.
Final value fees, listing fees, promoted-listing costs and payout settlements are pulled from the Sell Finances API and posted as charges or as a vendor invoice, depending on how your controller wants marketplace cost represented. The point is that a payout landing in the bank can be decomposed into the orders, refunds and fees that produced it, inside F&O, without a spreadsheet.
Everything is delivered as X++ extensions in your own model — Chain of Command and event handlers, no overlayering, so your other customizations and your future platform updates are not put at risk. Long-running work runs on the batch framework as SysOperation services with their own batch groups, recurrence and alerting. Integration state is stored in F&O with full payload capture, retry and dead-letter handling, and it is exposed through data entities so it can be read over OData by your monitoring or a support portal. Where a scenario is better served outside the ERP — a customer-service view, an approval screen, an alerting flow — we will say so and use Dual-write or Power Platform rather than bending F&O into a front end it was never meant to be.
Distributors, brands and retailers who already run F&O as the system of record and treat eBay as a real channel rather than an experiment. It suits organisations selling from multiple legal entities or multiple eBay sites, organisations with a warehouse team working in the Warehouse Management module, and finance teams who need marketplace revenue and cost to reconcile without manual journals. It is a poor fit if you want an unattended plug-in you never configure, or if your product data is not yet clean enough to publish.
1. Scoping call. We walk your estate: F&O version and update cadence, legal entities, eBay accounts and sites, product model, warehouse configuration, return policy, how finance wants fees represented, and what already exists in the way of middleware.
2. Fixed quote. You receive a written scope with the mappings, the batch jobs, the security artefacts and the acceptance criteria, priced as a fixed figure. Nothing is built before you approve it.
3. Build. Development happens against your F&O version in our environment, with checkpoints where you review working behaviour rather than status slides.
4. Install in test, then production. The deployable package goes into your Tier-2 sandbox through your LCS and DevOps pipeline. We configure it with you, run the mappings against your real catalogue, and only then schedule the production release. Typical end-to-end lead time is two to four weeks depending on scope.
5. Support. A defined support window follows go-live, covering defect fixes and eBay API version changes within the delivered scope, with the source code and documentation already in your hands.
There is no instant download and no free trial, because the product does not exist until we build it for your estate. We do not resell anyone else's connector, and we make no certification or partnership claims. What we commit to is a fixed scope, working code in your repository, an installation you watched happen, and a person who answers when something changes on the eBay side.
A short call to confirm the workflow, your platform version and where the integration boundaries sit.
You receive a written scope and a fixed price. Nothing is built until you approve it.
We develop against a copy of your configuration and test it there. Typically two to four weeks.
We install on your instance, hand over the source, and support it for twelve months.
Spends the day reconciling eBay orders against what the warehouse actually shipped and chasing listings that no longer match stock. A connector that turns every eBay order into a real F&O sales order, and pushes real availability back, removes the re-keying and the oversells that follow it.
Owns the F&O estate and has to keep it upgradeable while the business keeps asking for channels. Non-overlayering X++ extensions with source handover, batch jobs that log and retry properly, and a security model that fits existing roles mean the channel does not become an upgrade liability.
Cannot explain a marketplace payout without exporting three reports and building a spreadsheet each month. Having fees, refunds and settlements posted into F&O against the originating orders makes the payout reconcilable inside the ledger, with the dimensions the management pack already uses.
