As a result, you can deliver an exceptional experience to your customers, maintaining operational excellence.
Solution Design
We design SAP B1 and GXO integrations around the tension between financial control and high-volume fulfilment. SAP B1 typically maintains the master item record and financial truth, while GXO owns warehouse execution. A core design decision involves the timing of shipment confirmations. While real-time pushes to SAP B1 provide immediate visibility, we often model status updates to align with GXO's processing cycles, helping to simplify financial reconciliation. We prioritise the flow of fulfilment status back to SAP B1 to ensure invoice generation and stock adjustments are accurate. This approach involves a trade-off: intra-day reporting in SAP B1 may experience a short delay compared to warehouse floor activity, but it ensures that financial postings and inventory truth remain consistent. Finance closes the month with confidence while warehouse operations scale without technical drag.
Mapping data ownership and sync logic
The integration treats SAP B1 as the authoritative master for item records and customer financials, while GXO serves as the master for physical inventory levels. Sales orders are posted from SAP B1 to GXO for fulfilment as they are approved. Once GXO completes a pick and pack, shipment confirmations flow back to SAP B1 to trigger invoicing and stock reductions. To help prevent overselling, the integration synchronises inventory levels on a defined schedule, ensuring SAP B1 reflects warehouse reality. Monitoring is built into each step to detect data integrity issues, such as missing shipping codes or SKU mismatches, before they impact the customer.
Securing the orchestration layer with IPaaS
Cogent2 leverages IPaaS to integrate SAP B1 and GXO, ensuring secure connections between ERP and WMS/3PL systems. This approach simplifies data exchange, enhancing operational efficiency. IPaaS platforms with ISO 27001 and SOC 2 compliance and above provide robust security, safeguarding sensitive information. By connecting SAP B1 and GXO, businesses benefit from streamlined ERP and WMS/3PL processes, improving data accuracy and reducing manual intervention, while maintaining high security standards.
Surfacing delivery exceptions and ledger drift
Basic dashboards often fail to show why a shipment is stuck between the warehouse and the ledger. Our approach surfaces these hidden failures early, identifying where SAP B1 and GXO may have drifted out of sync. We monitor for specific exceptions, such as carrier service code mismatches that may prevent GXO from processing an order correctly. Instead of manual spot-checks, the system surfaces alerts when an order fails to post or a stock level adjustment is rejected. This visibility ensures that fulfilment delays are addressed quickly, protecting operational flow and customer satisfaction.
Handing over the operational model
Adoption focus is split between finance and operations. We hand over a practical operating model that defines how SAP B1 and GXO interact. Your finance team learns how to verify that warehouse shipments match ERP invoices, while operations teams are trained to monitor fulfilment status and inventory levels. We define what to check typically on a daily or weekly basis, such as pending shipments or stock-on-hand figures. Training is anchored in your specific design, showing teams how to read alerts from the integration layer and who owns exceptions like SKU mismatches or delivery failures. Documentation is provided as an operational reference for the people running the business, not a technical archive.
Proactive monitoring and data integrity maintenance
Ongoing support is focused on maintaining data integrity between SAP B1 and GXO. We monitor for sync failures, such as order rejections or inventory drift, identifying issues before they become financial liabilities. Our team handles troubleshooting to ensure technical issues are resolved without disrupting warehouse operations. We focus on continuous improvement, refining data mapping as your volume grows. This ensures the integration remains a reliable bridge between your office and the warehouse floor, using operational monitoring to surface exceptions before they impact fulfilment.
Common failures
Inventory latency and overselling
Operational impact: When stock level updates from GXO are delayed or fail, SAP B1's inventory position becomes unreliable. This directly leads to overselling, creating negative customer experiences and manual work for the CX team to cancel orders and for the finance team to process refunds. It also undermines confidence in stock buffers and replenishment forecasting.
Prevention / Action: The integration's design must treat GXO as the source of truth for physical stock levels, feeding delta updates to SAP B1 on a frequent, scheduled basis. Avoid full-catalogue syncs which cause system load. Implement robust error handling and a monitoring dashboard to flag SKUs with sync failures for immediate investigation by the operations team. Ensure the logic can handle multiple SAP B1 warehouse locations (OWHS) mapping to a single GXO facility without conflict.
Item master data mismatch
Operational impact: If a new product's Item Master Data is not created in GXO before stock arrives, the warehouse cannot process the goods receipt. This leads to costly operational delays, with inbound stock quarantined and unavailable for sale. It creates significant manual work for both merchandising and warehouse teams to resolve the data gap before stock can be put away.
Prevention / Action: Establish a strict operational process where SAP B1 is the exclusive owner of Item Master Data. The integration must be configured to push new and updated item records to GXO immediately upon creation or change in SAP B1. The process should prevent Purchase Orders from being raised for new items until the integration confirms the SKU has been successfully created in the GXO system.
Delayed or incomplete shipment confirmations
Operational impact: GXO dispatches an order, but the shipment confirmation message fails to update the Sales Order in SAP B1. This leaves customer service teams without tracking information to answer queries. More importantly, it blocks the finance team from issuing a timely invoice, leading to inaccuracies in revenue reporting and delays in the order-to-cash cycle.
Prevention / Action: The integration should actively poll for GXO's shipment advice file on a defined, frequent schedule. Logic must be built to handle potential data mismatches, using a shared order reference to link the shipment back to the correct SAP B1 Sales Order. An exception report should be generated daily for any confirmations that fail to match, allowing an operations user to resolve them manually and keep data flowing.
Misaligned returns and credit process
Operational impact: When GXO receives a returned item, a failure to trigger the corresponding documents in SAP B1 has direct financial impact. The finance team cannot issue the Credit Memo, delaying customer refunds and creating unnecessary CX workload. Furthermore, the returned stock is not booked back into inventory, making perfectly good items unavailable for resale.
Prevention / Action: Configure the integration to listen for 'Return Advice' notifications from GXO. This trigger should automatically create a Sales Return Order in SAP B1. A subsequent message, confirming the item has passed inspection at the warehouse, should then trigger the Goods Receipt and credit process. This keeps the physical, financial, and inventory records aligned.
Frequently asked questions
Who should own the master item data, SAP B1 or GXO?
In this operating model, SAP B1 must be the source of truth for all master item data, including SKUs, descriptions, and financial information. GXO's role is to manage physical inventory levels for those SKUs within the warehouse. The integration ensures new item records created in SAP B1 are synchronised to GXO, but GXO cannot create or change the core item data itself.
How do we prevent overselling when GXO holds the physical stock?
Overselling is caused by delays in synchronising GXO's inventory levels with SAP B1, which controls the available-to-sell quantity for your sales channels. A successful integration sends frequent inventory adjustments from GXO back to SAP B1. This ensures that as GXO processes shipments or receipts, the corresponding Item records in SAP B1 are updated, presenting an accurate stock position to prevent selling what you do not have.
We have multiple warehouse codes in SAP B1. How does that map to GXO?
Stock synchronisation often fails if multiple SAP B1 Warehouses (OWHS records) are mapped incorrectly to a single GXO facility. The integration requires clear logic to aggregate GXO's inventory updates and apply them to the correct warehouse record in SAP B1. Without this, you will face persistent inventory discrepancies and inaccurate stock data in your ERP.
What happens if GXO confirms a shipment before we post the goods issue in SAP B1?
This timing failure creates financial reconciliation problems during the order-to-cash process. If a GXO shipment confirmation triggers a delivery note in SAP B1 before the Post Goods Issue (PGI) is complete, the process will fail. Correct integration logic must queue the fulfilment update from GXO and only process it after the goods issue is successfully posted in SAP B1.
