InPost Lockers and Microsoft Dynamics Business Central
Integration Agency & Consultants
The reliability of an InPost locker integration often breaks down when physical parcel movements are not reflected in Microsoft Dynamics Business Central. At low volume, manual data corrections are manageable. At scale, unrecorded locker returns and shipment timeouts create significant reconciliation debt and inventory inaccuracy. We connect these systems to ensure locker metadata, tracking updates, and return notifications flow directly into your ERP, maintaining a clear line between warehouse operations and financial reporting.
Consulting
We connect your InPost Lockers and Microsoft Dynamics Business Central with Smart Lockers and ERP systems, ensuring your technology ecosystem works efficiently. Our consulting services are valuable because our system audit uncovers integration gaps and inefficiencies between InPost Lockers, Microsoft Dynamics Business Central, Smart Lockers, and ERP platforms. This enables our consultants and your team to take decisive action, helping your tech environment run smoothly and efficiently, so you can deliver a great experience to your customers.
Solution Design
Design for InPost and Microsoft Dynamics Business Central focuses on making the ERP the authoritative source for the order life cycle. We prioritise the flow of locker metadata directly into Business Central Sales Orders to ensure shipping labels are generated with correct routing. A key design decision involves the handling of returns. While outbound shipping is often triggered on a defined schedule to facilitate warehouse speed, we typically sync return and uncollected parcel data in a way that ensures financial reconciliation matches physical stock counts before inventory is adjusted. This trade-off ensures reporting accuracy but may require finance to accept a slight lag in intra-day return visibility. This model allows warehouse ops to work from Business Central as their primary interface while finance completes reconciliations with confidence that locker movements match the records.
Managing data flow through the order journey
The integration ensures Microsoft Dynamics Business Central remains the source of truth for the order life cycle while InPost manages the physical last-mile execution. To prevent data discrepancies, locker metadata is mapped to specific fields on the Sales Order, ensuring that routing information is preserved from order entry to label generation.
Data flow follows a strict operational sequence: - Order Post: Orders containing InPost metadata flow into Business Central, where contact details are validated for courier-compatible formatting. - Label Creation: When a warehouse shipment is prepared, the integration requests a label based on validated parcel dimensions and weights. - Fulfilment Sync: Shipment updates are sent to InPost only after the Business Central Warehouse Shipment is registered to avoid locker reservation timeouts. - Return Logic: Return events at InPost lockers are used to create return records in Business Central, ensuring inventory and financial records stay aligned with physical arrivals.
iPaaS
Leveraging IPaaS with SO 27001 and SOC 2 compliance and above ensures secure, efficient integration of InPost Lockers and Microsoft Dynamics Business Central with ERP and Smart Lockers. IPaaS simplifies connecting InPost Lockers, Microsoft Dynamics Business Central, ERP, and Smart Lockers, reducing risk and complexity. Security accreditations guarantee data protection, while automation and centralised management improve reliability and scalability for ERP and Smart Lockers integrations.
Exposing exceptions before they impact customers
Visibility between InPost Lockers and Business Central must account for the physical reality of parcel movement. Problems often manifest as discrepancies where an order appears fulfilled in the ERP but the locker reservation has timed out because of a delayed dispatch. Without granular monitoring, these exceptions remain hidden until customers complain about missing collection codes.
We focus on surfacing operational latency early. This includes tracking return timestamps and monitoring for label generation failures caused by formatting errors. By identifying these exceptions before they reach the warehouse dock, teams can resolve data mapping issues without stopping the physical flow of goods. This ensures that finance and operations share a mirrored view of inventory, whether it is in the warehouse or transit through a locker.
Operational manuals for warehouse and finance teams
Handover ensures that your finance, operations, and customer service teams own the day-to-day running of the InPost and Business Central integration. We provide an operational operating model that moves away from technical jargon. Your warehouse team learns to manage shipping label exceptions, while finance is trained on how to reconcile locker-based returns against Credit Memos. We define what to check on a regular basis, such as sync error logs, and who owns each exception type. This documentation is written for the people running the business, serving as a practical guide for resolving data mismatches or uncollected parcel alerts. Training is anchored in your specific configuration, ensuring teams know exactly where locker data lives in Business Central and how it impacts stock availability.
Maintaining data integrity after go-live
Ongoing support focuses on maintaining the integrity of the data flow between InPost and Business Central. We monitor for sync exceptions, such as failed label generations or tracking numbers that do not post back to the Sales Order, which can stall customer notifications. Our team provides operational ownership, ensuring that API changes or locker network updates do not disrupt your warehouse workflow. When issues arise, we prioritise resolving the root cause in the integration layer rather than relying on manual data patches in the ERP. This approach ensures that your inventory levels and financial reconciliations remain accurate without constant intervention from your internal teams. Monitoring typically includes tracking the life cycle of locker returns to prevent stock discrepancies.
Common failures
Premature shipment notification
Operational impact: Triggering 'Shipment Posted' updates to InPost before the Business Central Warehouse Shipment is successfully 'Registered' leads to locker reservation timeouts. Physical parcels remain on the dock while the locker window expires, forcing warehouse teams to void and recreate labels manually.
Prevention / Action: Configure the integration to hold status updates until the final registration event in Business Central. This ensures the locker reservation window only begins once the parcel has physically left the facility.
Parcel dimension and volume mismatch
Operational impact: If Business Central 'Item Volume' and 'Unit of Measure' limits are not synced with InPost locker sizes (Small, Medium, Large), shipments fail at the label generation stage. This creates a workflow fracture where orders are picked and packed only to be blocked because the parcel exceeds physical locker constraints.
Prevention / Action: Implement validation at the point of order entry or release in Business Central. The integration should check total order volume against InPost's physical constraints before the order reaches the warehouse floor.
Invalid phone number formatting
Operational impact: InPost uses the mobile number as the primary key for SMS collection codes. If the 'Ship-to Phone Number' in Business Central is missing or contains non-numeric spaces, API requests to generate labels will fail. This forces customer service to manually correct records and re-sync orders.
Prevention / Action: Apply regex validation during the Business Central 'Release' action. Ensuring the phone number follows the strict ISO E.164 format before the data hits the integration layer prevents label failures during peak dispatch hours.
Frequently asked questions
How does the integration handle customer returns sent back through an InPost locker?
When a customer scans a return at an InPost locker, the integration can automatically create the corresponding return authorisation and credit documents in Microsoft Dynamics Business Central. This ensures that the stock level for the returned Item record is accurately updated once it's processed. Without this, returned inventory is not visible in your ERP, leading to inaccurate stock counts and missed sales opportunities.
What happens if a customer tries to ship an item that is too large or heavy for an InPost locker?
This can cause significant fulfilment delays and require manual intervention from your customer service team. A properly configured integration uses the weight and dimension data from the Item record in Microsoft Dynamics Business Central to dynamically hide InPost as a shipping option during checkout for any non-compliant SKUs. This prevents an impossible fulfilment request from ever becoming a Sales Order.
How does this integration help our finance team with reconciling InPost shipping costs?
The integration is designed to capture shipping fees from InPost Lockers and post them as costs against the corresponding Sales Order in Microsoft Dynamics Business Central. This can be configured to happen as journal entries are created for financial reconciliation. This process avoids hours of manual work allocating shipping costs at month-end and gives you an accurate view of order profitability.
When we ship an order via InPost, how quickly is the stock level updated in Business Central?
The integration updates Microsoft Dynamics Business Central as soon as the shipment is confirmed in the InPost system, triggering the creation of an Item Fulfilment. This reduces the available quantity for that SKU, providing timely inventory data across your business. This is critical for preventing overselling of a product that has already been dispatched but not yet recorded in the ERP.
