Clarus WMS connects to Linnworks so operations teams can manage orders, inventory and despatch from one place. Once connected, Linnworks sales orders pass into Clarus WMS, you allocate by quantity, and shipment confirmations with tracking return to Linnworks. Inventory availability stays in sync so channels connected to Linnworks reflect accurate stock. Label data and sales order line information are shared between systems for clean packing and consistent updates. No third-party middleware or coding is required.
What are WMS integrations with Linnworks and how does Clarus support them?
A WMS integration with Linnworks links your warehouse processes to the order management that Linnworks provides. The aim is straightforward, orders in from Linnworks, controlled allocation and fulfilment in Clarus WMS, then tracking and stock updates out to Linnworks.
Clarus WMS supports this model in a dependable, warehouse-first way:
- Sales order pass-through from Linnworks to Clarus
New Linnworks orders import into Clarus WMS with headers, customer and delivery details, and full line items with quantities, ready for allocation and fulfilment. - Allocate by quantity inside Clarus
Teams allocate stock by quantity at order or line level before work reaches the floor. This keeps reservations explicit and controlled. - Label data and sales order line information shared
Clarus keeps the label fields and line-level detail you need so printed labels and confirmations reflect what is actually in the parcel. - Orders, tracking and inventory kept in sync
After despatch, Clarus posts shipment confirmations with tracking back to Linnworks and updates available inventory so connected channels remain accurate.
The outcome is a WMS-led workflow that keeps Linnworks activity aligned with what is physically possible in the warehouse.
How does Clarus manage order and inventory syncing with Linnworks?
Clarus WMS focuses on the essential data paths that keep operations predictable and easy to support.
Inbound to Clarus WMS
- Linnworks sales orders arrive with buyer details, delivery addresses and line items with quantities, plus fulfilment notes that matter for packing.
- Order status visibility in Clarus shows new, in progress and completed orders in one view for simpler triage.
Within Clarus WMS
- Allocation by quantity reserves what you plan to ship, visible to supervisors and pick teams.
- Picking and packing follow your configured workflows, including scanner confirmations where used.
- Label generation uses shared label data and line context so labels and documentation match parcel contents.
Outbound back to Linnworks
- Shipment confirmations including tracking numbers are posted at despatch.
- Inventory updates adjust available stock following picks, receipts and adjustments.
- Line-level fidelity is preserved so what you fulfil is what Linnworks records.
If Linnworks is feeding multiple marketplaces and web stores, this approach helps keep those downstream channels in step with warehouse truth.
Is any development work needed to set up WMS integrations with Linnworks?
No. The Linnworks connection is provided natively in Clarus WMS. You authorise Clarus with your Linnworks 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 for a standard deployment. If your organisation prefers staged rollouts, you can connect a test environment first, validate order import and updates, then connect live when ready.
What’s the fastest way to connect Clarus WMS to Linnworks?
The quick start is designed to be simple.
- Connect your Linnworks account to Clarus
Authorise Clarus WMS with your Linnworks credentials and confirm the required scopes. - Orders, tracking and inventory begin syncing
New Linnworks orders appear in Clarus. When you complete shipments, tracking and confirmations post to Linnworks, and inventory availability updates follow. - Manage everything from one dashboard
Allocate by quantity, run picks, print labels and confirm despatch in Clarus. Monitor orders and stock across all connected channels in one place.
No third-party middleware or coding is required for the standard flow.
How does allocation by quantity help with Linnworks fulfilment?
Allocation by quantity gives precise control 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 making commitments explicit 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 Linnworks?
Labels and tracking are central to a clean buyer experience and to reliable customer service.
- Label data available where needed
Clarus stores the label fields required for accurate printing and reconciliation alongside line-level detail. - Tracking returned to Linnworks
When you despatch, Clarus posts the tracking reference and carrier details with the shipment confirmation. - Line-level accuracy
Confirmations reflect the items actually packed, which supports clear messaging to buyers and accurate reporting.
If you use multiple carriers, Clarus records the service used and the tracking reference per parcel so Linnworks receives the correct details.
What operational visibility does Clarus WMS provide for Linnworks?
The integration provides the views operations leaders rely on day to day:
- Unified order board for new, allocated, picking and shipped Linnworks orders with filters for date range and service.
- Stock views showing available, allocated and on-hand quantities to inform allocation decisions.
- Exceptions highlighting orders that cannot be fully allocated 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 figures as estimates, however teams typically find it simpler to manage multi-channel fulfilment from one WMS dashboard once connected.
How does inventory synchronisation work across Linnworks and other channels?
Clarus WMS treats the warehouse as the source of truth for stock on hand. When you pick and despatch, Clarus adjusts on-hand and available quantities, then posts updated availability to Linnworks. If Linnworks is connected to multiple channels, those channels receive accurate stock positions from Linnworks based on the WMS updates. Where you operate more than one warehouse, Clarus can reflect location-specific stock and publish the right totals to Linnworks in line with your listing strategy.
What data is exchanged between Linnworks and Clarus WMS during the order lifecycle?
The integration concentrates on the fields warehouse and customer service teams use every day.
- From Linnworks to Clarus
Order headers, customer and delivery details, service selections where applicable, and line items with quantities and notes relevant to packing. - Within Clarus
Allocation by quantity, pick and pack confirmations, label data fields and tracking references. - From Clarus to Linnworks
Shipment confirmations with tracking numbers, line-level fulfilment details and inventory availability updates.
By focusing on these fields, the flow remains stable and predictable.
Are partial shipments and pre-despatch changes supported?
Yes. Clarus WMS supports partial shipments when required to meet service levels. You can allocate and ship the available quantities by line, then complete the remainder when stock arrives. Clarus posts what was shipped to Linnworks with accurate line-level detail, and inventory updates reflect the change. If an order changes in Linnworks before despatch, for example an address edit or a quantity adjustment, Clarus receives the update and shows it in your dashboard so you can act accordingly.
How do I operate day to day once Linnworks and Clarus are connected?
You can run the day from the Clarus dashboard:
- Review incoming Linnworks orders and filter by service or promised date.
- Allocate by quantity to commit stock to the orders you plan to pick.
- Run picking using your preferred method, single order, batch or wave.
- Pack and label with label data shared between Clarus and Linnworks so labels are correct.
- Confirm despatch so tracking and shipment updates flow to Linnworks.
- Monitor inventory to keep on-hand and available levels accurate across all connected channels.
This keeps the WMS at the centre of fulfilment while your Linnworks estate stays in sync.
Implementation considerations for technical buyers
The Linnworks integration is delivered natively within Clarus WMS, which reduces moving parts. There is no external middleware to maintain for a standard deployment and no separate integration vendor to manage. Access control, audit and environment separation are handled in Clarus. You can connect a staging tenant first if required, prove the flow, then connect live.
For reporting, Clarus provides operational dashboards for orders, inventory and despatch. If you maintain a data warehouse, operational data can be exported from Clarus and reconciled with Linnworks reporting. The integration keeps warehouse truth intact and avoids duplication of logic.
