Solution Design
For the Khaos Control and John Lewis Marketplace integration, we prioritise inventory accuracy as the primary design driver. Khaos Control is designated as the system of record for all stock levels and product data, with availability pushed to the marketplace on a defined schedule. We typically choose a batched approach for financial postings to allow for easier reconciliation against marketplace settlement reports. This involves an intentional trade-off where intra-day financial reporting may lag, but the month-end close is more accurate. Orders are sequenced to post into Khaos Control quickly after marketplace confirmation to trigger the fulfilment process. This design ensures that the warehouse team works off current demand while finance remains grounded in reconcilable data.
Synchronising stock levels and order sequences
Khaos Control acts as the system of record for inventory and customer data, with orders from John Lewis Marketplace posting into Khaos Control for fulfilment. To prevent overselling, the integration pushes stock levels back to the marketplace using available-to-sell logic, accounting for physical stock less existing allocations. Once the warehouse team allocates stock to an order in Khaos Control, the updated availability is reflected on the storefront. This sequencing ensures that warehouse teams see accurate demand and prevents lost sales from stock drift.
Orchestrating workflows through secure middleware platforms
Leveraging IPaaS with ISO 27001 and SOC 2 and above security accreditations enables secure, efficient integration between Khaos Control, John Lewis Marketplace, ERP systems, and other Marketplaces. This approach simplifies connecting Khaos Control with John Lewis Marketplace and ERP platforms, ensuring data protection and compliance. IPaaS platforms reduce manual effort, support scalability, and maintain robust security, making integration with Marketplaces straightforward and reliable.
Surfacing sync failures and reconciliation gaps
Standard marketplace dashboards often hide the operational gaps that occur between systems. We focus on surfacing sync failures and reconciliation gaps where marketplace orders do not match ERP postings. Our approach monitors these flows to detect when a stock item sequence is missing or a shipping update has failed to post back to the marketplace. This detection helps prevent customer service issues caused by missing tracking numbers or incorrect stock signals.
Operational handover for finance and operations
Handover focuses on the operations and finance teams who manage the daily system performance. We provide an operating model that defines Khaos Control as the source of truth for stock and the marketplace as the sales driver. Your team will learn how to check sync logs, respond to mapping alerts, and handle order exceptions. Finance is trained on how to reconcile the financial postings against marketplace reports to assist with the month-end process. All documentation is provided as an operational manual for your staff, focusing on daily tasks and alert responses rather than technical reference.
Monitoring exceptions and inventory drift issues
Operational support focuses on identifying and resolving sync exceptions before they impact fulfilment. We monitor the integration behaviour for matching errors, failed order posts, and inventory drift. By surfacing specific data exceptions that require intervention, we ensure the team can focus on shipping orders rather than troubleshooting technical links. This approach provides visibility into the data issues that commonly threaten month-end accuracy.
Common failures
Inventory latency and overselling
Operational impact: When stock levels sent to John Lewis from Khaos Control lag behind actual warehouse activity, you risk overselling popular items. This forces customer service to cancel orders and manage poor reviews, while the fulfilment team is left with unfulfillable Sales Orders. Finance teams then face increased credit card chargebacks and refund processing.
Prevention: The integration must treat Khaos Control as the single source of truth. Stock updates should be pushed to John Lewis on a defined schedule. A stock buffer should be configured within the integration logic to create a safety margin, protecting against overselling on fast-moving products during peak periods.
SKU mismatch and blocked orders
Operational impact: If a John Lewis order contains a SKU that does not match a Khaos Control 'Stock Code', the order will fail to import. This stalled order delays fulfilment and can lead to marketplace SLA breaches. Operations teams are forced into manual data correction, searching for the correct item to re-process the order, which slows the order-to-dispatch workflow.
Prevention: Enforce a process where Khaos Control is the master system for product data. No SKU should be active on John Lewis until the Stock Code is confirmed in Khaos Control. The integration should provide clear alerts for mismatch errors, routing them to a specific user for immediate resolution.
Dispatch confirmation failures
Operational impact: Even when shipments are processed and despatched in Khaos Control, a failure to sync the tracking number back to John Lewis creates a compliance risk. This violates marketplace SLAs and can lead to account suspension. It also triggers avoidable contacts from customers asking for order status.
Prevention: The integration must map Khaos Control courier identifiers to the codes required by John Lewis. A retry mechanism should handle temporary connection issues, with persistent failures flagged in an exception report for the fulfilment team to address manually.
Payout and reconciliation debt
Operational impact: Finance teams often receive bulk payouts from John Lewis that do not easily map to individual Sales Orders in Khaos Control. When commission fees and deductions are not clearly associated with specific orders, the month-end close becomes a manual data-matching exercise. This obscures true channel profitability and delays financial visibility.
Prevention: Ensure the John Lewis 'Customer Order Number' is stored in a searchable external reference field on every Khaos Control Sales Order. Settlement reports should be used to post summary journals, providing an auditable link between John Lewis payouts and your internal sales data.
Frequently asked questions
Which system becomes the source of truth for inventory?
Khaos Control acts as the central source of truth for all inventory in this model. The integration pushes stock figures from Khaos Control to John Lewis Marketplace on a defined schedule. This ensures marketplace availability reflects actual warehouse stock, preventing overselling and protecting your seller metrics.
What happens if our SKUs in Khaos Control do not match the product codes on John Lewis?
An exact match between the John Lewis SKU and the Khaos Control 'Stock Code' is required for order processing. If a match is not found, the automated creation of the Sales Order in Khaos Control will fail. This creates manual overhead, requiring intervention to find the correct item and fulfill the order, which introduces human error risk.
How does John Lewis know when we have despatched an order from Khaos Control?
When an order reaches 'despatched' status in Khaos Control, the integration triggers a dispatch confirmation to John Lewis Marketplace. This includes the carrier code and tracking number required by John Lewis. Failure to sync this data promptly can result in poor seller performance metrics and increased customer service enquiries.
Will this integration help our finance team with the month-end close?
Yes. By ensuring John Lewis orders post accurately into Khaos Control, the integration eliminates manual data correction. This creates a reliable data set for financial reconciliation, allowing the finance team to close the month faster because the sales data in Khaos Control matches the marketplace activity.
How do we prevent overselling during peak periods?
The integration maintains Khaos Control as the master record. When a Sales Order is created in Khaos Control, stock is allocated, and the updated availability figure is pushed to John Lewis. This prevents stock from being sold twice, ensuring you maintain a high seller rating and avoid order cancellations.
