With our expertise, you can deliver a reliable experience to your customers and keep your operations running smoothly as your business grows.
Solution Design
Our team puts you in the driving seat of your Clarus WMS and Fulfil integrations, designing a future-proof WMS/3PL and ERP ecosystem that’s built for your business. We work side-by-side with you to create a blueprint for success, ensuring Clarus WMS and Fulfil work in harmony with your ERP and WMS/3PL stack. Smart, well-executed integrations save time, cut hassle, and lay the groundwork for sustainable growth.
Syncing transactional data and stock movements
The integration establishes Fulfil as the central source of truth for orders and master data, pushing fulfilment-ready orders into Clarus WMS for execution. Once the pick-pack-ship cycle is completed in the warehouse, Clarus returns the fulfilment status and tracking data to Fulfil to trigger customer notifications. We design these flows to prevent inventory drift, ensuring levels stay synchronised at the SKU level. Monitoring is embedded into the handoff, surfacing alerts if an order fails to transmit or if a tracking update is rejected. By prioritising data integrity at the point of transfer, the integration ensures your ERP accurately reflects physical warehouse movements.
Orchestrating workflows through secure middleware infrastructure
Leveraging IPaaS with ISO 27001 and SOC 2 and above security accreditations, Clarus WMS and Fulfil integrations for WMS/3PL and ERP systems are delivered efficiently and securely. IPaaS enables Clarus WMS and Fulfil to connect ERP and WMS/3PL platforms, automating data flows and reducing manual errors. This approach ensures robust compliance, scalability, and data protection, making integration projects faster, safer, and more reliable.
Surfacing exceptions and synchronisation errors early
High-level dashboards showing total order counts often hide the small, compounding sync failures that eventually break your reconciliation. We provide visibility into the specific exceptions that matter, such as orders stuck between Fulfil and Clarus WMS or SKU mismatches that block fulfilment. Instead of waiting for a stock issue to arise, the platform surfaces these data gaps early. This allows operations to resolve synchronisation errors before they impact the customer. Our monitoring turns hidden technical friction into actionable tasks, ensuring inventory levels and fulfilment statuses remain aligned across both platforms.

Proactive monitoring of the fulfilment queue
Post-launch, we maintain operational ownership of the Clarus and Fulfil link through continuous monitoring. We do not just respond to tickets; we proactively identify where data mismatches are creating backlogs in your fulfilment queue. Escalation paths are defined around business impact, ensuring that a sync failure is prioritised correctly. By monitoring the integration at the transaction level, we ensure that as your order volume grows, the connection between your warehouse and ERP remains stable and reconciled.
Common failures
Mismatched SKU formats
Operational impact: If Fulfil's master SKU data contains leading zeros or special characters, Clarus WMS may ignore or strip them on import. This causes Sales Orders to fail when they reach the warehouse because the SKUs do not match any known product. The fulfilment team must then manually investigate and correct each failed order, causing significant dispatch delays and creating a backlog of unsent packages.
Prevention / Action: The integration's data mapping logic must enforce SKU format consistency before data is exchanged. Fulfil must be designated the absolute source of truth for all Item master data, and Clarus configured to respect its formats. Implement pre-sync data validation and an exception queue to catch and hold any non-compliant SKUs, alerting the merchandising team before they can cause downstream failures.
Inventory latency and overselling
Operational impact: Stock level updates from Clarus, especially after a large goods-in delivery or cycle count, can be delayed in updating Fulfil. During this latency period, Fulfil's view of available stock is inaccurate, creating a high risk of overselling. This directly impacts the CX team who manage cancelled orders and damages customer trust, while also corrupting the stock asset data used by the finance team.
Prevention / Action: Design the inventory sync with a focus on deltas, updating only SKUs with recent stock movements to reduce sync time and API load. The frequency of the sync should be determined by sales velocity and operational tolerance for overselling. The integration must feature robust monitoring to alert the operations team if the sync process fails or is delayed, enabling a quick decision to pause channels if overselling risk is high.
Incomplete fulfilment updates from split shipments
Operational impact: An order split into multiple consignments in the warehouse can cause reconciliation failures. Clarus may send a fulfilment update for the first box, which Fulfil might incorrectly process as the entire order being complete. The remaining items are left stranded with no open fulfilment request, leading to incomplete orders, customer complaints, and costly follow-up shipments to correct the error.
Prevention / Action: The integration must be designed to handle partial shipments natively. Each consignment leaving Clarus needs a unique identifier that can be reconciled against the parent Sales Order in Fulfil. The order in Fulfil should only be marked 'complete' once all expected Item Fulfilments have been received, preventing premature closure of the order.
Disconnected returns and stock updates
Operational impact: When the CX team processes a return in Fulfil, if this does not automatically create a Return Merchandise Authorisation (RMA) in Clarus, the warehouse has no record of the expected inbound item. The physical return cannot be processed efficiently, causing delays in refunding the customer. More importantly, the returned stock is not correctly added back to sellable inventory, leading to a growing discrepancy between physical stock and the inventory levels in Fulfil.
Prevention / Action: The returns workflow must be mapped as a bidirectional process. A return initiated in Fulfil must trigger the creation of an expected inbound RMA in Clarus. Once the warehouse processes the return, the receipt confirmation and any stock condition changes (e.g. 'damaged', 'resellable') must be fed back to Fulfil to update inventory levels and ensure the item record is accurate.
Frequently asked questions
If Fulfil is our system of record, what happens if we adjust stock levels directly in Clarus WMS?
The standard operating model designates Fulfil as the source of truth for the master inventory record. While Clarus WMS manages physical warehouse counts, any adjustments made there must sync back to Fulfil to update the centralised stock level. Making direct, un-synced changes in Clarus will cause inventory data to diverge, creating a high risk of overselling items that are not truly available.
Why does our available inventory in Fulfil not match the physical stock count in the Clarus WMS?
This is a common commercial trigger for this integration, often caused by failed or delayed syncs for specific operational processes. For instance, if a stock receipt or a customer return is processed in Clarus WMS but the confirmation fails to update the inventory level in Fulfil, your central ERP will not have an accurate view of available stock. This leads directly to inaccurate stock levels on your sales channels and affects purchasing decisions.
Can our warehouse team create or edit sales orders directly within Clarus WMS?
In a correctly configured integration, Clarus WMS should only receive order information from Fulfil, which acts as the system of record for all Sales Orders. Allowing order creation or editing within Clarus is a significant operational risk, as the core customer record and financial data for that order would not exist in your Fulfil ERP. This creates major reconciliation issues for the finance team during month-end close.
How does the integration handle partial shipments if an order cannot be completely fulfilled?
Fulfil will send a Sales Order to Clarus WMS for fulfilment, but Clarus might only be able to ship part of it. The integration must be configured to send a shipment confirmation for the dispatched items, which updates Fulfil to a 'Partially Fulfilled' status. If the integration simply closes the order, the remaining items will never be shipped, leading to a poor customer experience and manual effort to resolve the order.
We use leading zeros and special characters in our SKUs. Will this cause order sync failures?
This is a frequent point of failure in WMS integrations, as a mismatched SKU will cause an order to be rejected. When Fulfil sends a Sales Order to Clarus, the integration must ensure the SKU value is transmitted perfectly without being altered by either system. For example, if Clarus WMS strips a leading zero from a SKU, it will not find a matching item record, causing the order to fail and halting the entire fulfilment process.
