Prima and GXO
Integration Agency & Consultants
At scale, the gap between physical stock in GXO and financial records in Prima becomes a source of reconciliation debt. When orders desynchronise or units of measure are mapped incorrectly, the result is overselling and manual month-end adjustments that slow down the finance team. We connect Prima with GXO to mirror warehouse activity accurately in your ERP, ensuring that every dispatch and receipt is reflected in your journals without manual intervention. This reduces operational latency and protects customer satisfaction during peak periods.
Mapping item masters and system audits
Prima and GXO integration is made simple, connecting your ERP and WMS/3PL systems for efficient operations. Our consulting services are invaluable, with system audit services that allow our consultants and your team to identify and resolve issues across Prima, GXO, ERP, and WMS/3PL platforms. This ensures your tech ecosystem runs efficiently, supporting a smooth customer experience. By leveraging our audits, you gain actionable insights, enabling your business to optimise processes and maintain reliable connections between Prima, GXO, and your wider technology stack.
Solution Design
The Prima and GXO integration is designed with Prima as the central authority for financials and item masters, while GXO manages the inventory lifecycle. We usually prioritise scheduled order transmission to the warehouse to allow for validation, while warehouse status updates are frequently batched. A critical design decision involves how returns and stock adjustments flow back into Prima: we ensure these movements are mapped to appropriate categories to maintain audit trails. This setup involves a trade-off where batching updates reduces system load but requires teams to rely on defined intervals for stock truth. The resulting operating model ensures that finance closes month-end off Prima, while operations manages physical velocity through GXO with confidence in the data connection.
Synchronising orders and unit of measure
The integration establishes Prima as the system of record for master item data and financial accounts, while GXO manages the physical fulfilment cycle. Orders flow from Prima to GXO for dispatch, with status updates and tracking data feeding back to trigger invoicing and customer notifications. Precise mapping of 'Unit of Measure' between the systems is required to prevent pick quantity errors at the warehouse.
Inventory levels sync between systems to prevent overselling, using logic that accounts for warehouse allocations. GXO's receipt acknowledgements trigger Purchase Order Receipts in Prima, requiring precise line-level mapping to ensure the fulfilment record is accepted. Monitoring is embedded at the transaction level to detect stalled orders or SKU validation errors before they disrupt warehouse operations or the month-end close.
Orchestrating secure flows via certified IPaaS
Leveraging IPaaS, Prima and GXO integrations with ERP and WMS/3PL systems are delivered efficiently and securely. IPaaS platforms with ISO 27001 and SOC 2 and above accreditations ensure robust data protection. Prima and GXO benefit from simplified ERP and WMS/3PL connectivity, reducing manual effort and risk. Using IPaaS provides agility, centralised management, and compliance, making integrations more reliable and secure for all parties involved.
Detecting SKU mismatches and sync drift
Standard dashboards often miss the quiet failures that impact margin over time. Visibility means knowing exactly where an order sits in the handoff between Prima and GXO, and why it hasn't moved. We surface operational exceptions such as SKU mismatches or stock sync drifts that cause overselling. By isolating these failures early, teams can resolve them within the warehouse window rather than discovering them during a month-end reconciliation. Visibility is about data integrity, not just status light monitoring.
Handover for finance and operations teams
Handover ensures that finance, operations, and ecommerce teams can confidently manage the integration. We establish a clear operating model where your team owns specific exception types, such as mapping new codes or resolving stock variances. Operations teams learn to monitor dispatch alerts, while finance checks at agreed intervals for reconciliation gaps between shipments and invoices. Documentation is provided as a practical operational reference, detailing exactly who should investigate when a sync fails and how to verify stock truth. This handover is based on your specific design, ensuring that your teams are equipped to handle day-to-day exceptions without external technical intervention.
Maintaining data integrity after go live
Support is focused on maintaining the integrity of the data flow. We monitor for technical failures and operational exceptions that could lead to stock drift or fulfilment delays. When an issue arises, we provide the context needed for your operations or finance teams to resolve the underlying cause. Ownership of the integration means we proactively identify bottlenecks in the sync between Prima and GXO, ensuring that your month-end reconciliation remains clean as you scale.
Common failures
Unit of Measure (UOM) mapping errors
Operational impact: A frequent failure occurs when Prima passes a multi-unit quantity but the warehouse interprets the instruction as individual units. This results in pickers sending entire cases instead of individual items, leading to rapid stock depletion, financial variance, and shipping errors that are difficult to untangle during month-end close.
Prevention / Action: The integration must explicitly map Prima’s UOM codes to the warehouse's expected base units. Validation should be applied at the translation layer to ensure any unrecognised UOM triggers an immediate hold rather than a default quantity.
Missing line-level references in receipts
Operational impact: When a receipt acknowledgement is sent to Prima, the data must include exact line-number references. If these are missing, the ERP may reject the entire receipt batch. This creates a visibility fracture where stock has been physically received but remains 'unavailable' in the system, preventing sales and causing reconciliation debt.
Prevention / Action: Ensure the integration mapping preserves internal line IDs through the outbound purchase order and requires their return in the inbound message. Implement monitoring to alert teams specifically to batch rejection errors so they can be resolved before the stock record drifts.
SKU validation rejections
Operational impact: If ERP product codes contain spaces or specific character types that the warehouse system rejects, orders may fail silently. This leads to orphaned records that appear dispatched in the ERP but do not exist in the warehouse, resulting in fulfilment delays and a breakdown in inventory truth.
Prevention / Action: Implement a data-cleansing layer that validates SKU strings before transmission. Use a confirmation loop that ensures the item record is active in the warehouse system before permitting order authorisation in the ERP.
Frequently asked questions
How is the source of truth for inventory managed between Prima and GXO?
GXO acts as the lead system for physical stock levels and returns. Prima serves as the financial system of record, holding master item data. The integration ensures that GXO's master stock levels are periodically synced into Prima. Despatch confirmations from GXO update the order status in the ERP, maintaining inventory accuracy across systems.
Our month-end close is difficult because of stock discrepancies. How will this integration help?
The integration automates the sync of stock levels and receipt acknowledgements from GXO to Prima. This reduces manual reconciliation effort and prevents the discrepancies typically revealed during period close. By aligning GXO's physical counts with Prima's financial records on a defined schedule, the finance team avoids chasing data gaps between the warehouse and the ledger.
What happens if Prima and GXO SKU formats don't match?
A common failure occurs when Prima product codes contain special characters or spaces that GXO rejects, leading to silent item creation failures. We implement SKU cleaning and validation rules to ensure strings are alphanumeric before transmission. This prevents the operational stall that occurs when the warehouse cannot acknowledge an item sent from the ERP.
How are returns handled in this integration?
GXO operates as the lead system for processing returns. When a successful receipt is recorded in the warehouse, the integration triggers a credit memo request back into Prima. This ensures that the return-to-shelf process is immediately reflected in the financial system, allowing retailers to process refunds once the physical stock is confirmed.
How does the integration handle different units of measure?
Mapping Prima’s 'Unit of Measure' (UOM) to GXO’s base units is a frequent failure point. GXO typically expects 'EA' (each), while Prima may pass 'PACK' or 'BOX'. If these are not precisely translated, picking quantity errors occur. The integration layer enforces this mapping to ensure warehouse pick accuracy matches the customer’s order.
