Clarus WMS connects directly to eBay so operations teams can manage orders, inventory and despatch from one place. Once connected, eBay sales orders pass into Clarus, you allocate by quantity in the WMS, and shipment confirmations with tracking flow back to eBay. Inventory availability is kept in sync so listings remain accurate. Label data and order line details are shared between systems to keep packing and customer updates consistent. No third-party middleware or coding is required.
What are WMS integrations with eBay and how does Clarus support them?
A WMS integration with eBay links your marketplace storefront to your warehouse processes. The aim is straightforward, orders in, controlled allocation and fulfilment in the WMS, then tracking and stock updates out.
Clarus WMS supports this flow in a practical, reliable way:
- Sales order pass-through from eBay to Clarus
New eBay orders are pulled into Clarus with headers, customer and delivery details, and full line items, ready for allocation and fulfilment. - Allocate by quantity inside Clarus
Teams allocate stock by quantity at order or line level. You maintain control over what is committed before picking begins. - Label data and sales order line information shared
Label fields and line-level details are available where you need them, so printed labels and confirmations align to what is actually in the parcel. - Orders, tracking and inventory kept in sync
After go-live, Clarus posts shipment confirmations with tracking to eBay and updates available inventory, helping prevent oversell events.
The result is a WMS-led workflow that keeps marketplace activity aligned with your warehouse reality.
How does Clarus manage order and inventory syncing with eBay?
Clarus focuses on the essential data paths that keep operations predictable.
Inbound to Clarus
- eBay sales orders arrive with buyer and address details, line items and quantities, and any fulfilment notes relevant to packing.
- Order status is visible in Clarus so teams can filter new, in progress and completed orders.
In the WMS
- Allocation by quantity is performed to reserve stock for the orders you plan to pick.
- Picking and packing follow your configured workflows using scanners where applicable.
- Label generation uses the shared data fields so labels reflect the actual contents and service used.
Outbound to eBay
- Shipment confirmations including tracking numbers are posted to eBay once a parcel is despatched.
- Inventory updates reflect changes to on-hand and available stock following picks, receipts and adjustments.
- Line-level fidelity is maintained so what you fulfil is what eBay records.
If you run multiple channels, Clarus applies the same approach to each connection, keeping the WMS as the source of truth for stock on hand.
Is any development work needed to set up WMS integrations with eBay?
No development work is required for a standard setup. The eBay integration is provided natively in Clarus WMS. You connect your eBay account, confirm permissions for order import and stock export, then choose a small set of operational preferences. There is no middleware to host and no custom scripts to maintain.
If your organisation prefers staged rollouts, you can connect a test environment first, validate order import and updates, then connect live when ready.

How does WMS allocation by quantity help with eBay fulfilment?
Allocation by quantity in Clarus gives you precise control over commitments before work starts on the floor.
- Prioritise orders by promised date or service.
- Reserve partial quantities when only part of a line is available, then complete the balance later.
- Avoid double allocation by reserving stock explicitly in the WMS.
Allocation states are visible to supervisors and pick teams so everyone understands what is committed and what remains open.
How are labels, tracking and shipment updates handled for eBay?
Labels and tracking are central to a clean marketplace experience.
- Label data available where needed
Clarus stores the label data points required for accurate printing and reconciliation. - Tracking returned to eBay
When you complete a shipment, the tracking reference and carrier details are sent to eBay with the confirmation. - Line-level accuracy
Shipment messages align to the items actually packed, which supports clear customer communications.
If you use multiple carriers, Clarus records the service used and returns the correct tracking per parcel.
How does Clarus WMS keep inventory accurate across eBay and other channels?
Clarus treats the WMS as the single source of truth for stock on hand. When you pick, pack or receive goods, Clarus updates on-hand and available quantities and then syncs the relevant availability to eBay. If you also connect other channels, Clarus applies the same update logic to each connection so availability stays consistent.
Where you operate more than one warehouse, Clarus can reflect location-specific stock and publish the right totals to eBay in line with your listing strategy.
What reporting and visibility do operations leaders get for eBay?
The integration provides the views teams use day to day:
- Unified order board for new, allocated, picking and shipped eBay orders with filters for date range and service.
- Stock views showing available, allocated and on-hand quantities to inform allocation decisions.
- Exceptions for orders that cannot be allocated fully so you can replan or expedite replenishment.
- Despatch and tracking reports summarising shipped orders and carrier references for customer service follow-up.
Any time saving will vary by operation, treat estimates as indicative, however teams typically find it simpler to run marketplace fulfilment from one WMS dashboard once connected.
