Inventory Management for Amazon FBA
The balancing act between Amazon FBA and Inventory Management usually becomes painful when stock levels drift, leading to mounting storage fees or lost sales from stockouts. At scale, inaccurate stock data makes replenishment decisions difficult and compromises financial reporting. We establish reliable data flows that treat FBA as the fulfilment engine and your management system as the planning primary, ensuring you hold enough stock to meet demand without over-committing capital to unnecessary storage costs.
Auditing your FBA and IMS landscape
We swiftly connect your Amazon FBA and Inventory Management systems with Inventory Planner and other Marketplaces, ensuring your operations run efficiently. Our consulting services are invaluable, offering in-depth system audits that empower both our consultants and your team to take decisive action. These audits uncover issues across Amazon FBA, Inventory Management, and Marketplaces, enabling smoother workflows and better performance. By optimising your tech ecosystem, you can deliver a superior customer experience and keep your Inventory Management and Marketplaces operating at their best.
Solution Design
For the Amazon FBA and Inventory Management pair, we prioritise the inventory reconciliation loop. Our design typically treats Amazon FBA as the source of truth for physical stock availability, while the IMS dictates replenishment logic. We often face a trade-off between real-time inventory updates and system stability. While real-time sync reduces stockout rate, frequent polling can strain API limits. We usually implement a buffered sync to protect performance. Orders are typically sequenced to post when FBA confirms fulfilment, ensuring your system records match actual shipping events. This design means finance can close monthly with confidence in stock figures, while operations work from a de-duplicated view of available stock across Amazon depots.
Synchronising stock levels and fulfilment events
In this model, your inventory management system acts as the master for replenishment planning, while Amazon FBA is the authority for physical availability. The integration captures FBA stock levels and synchronises them to the inventory system, ensuring sellable quantities are isolated from units currently being moved between fulfilment centres. Order records are processed once Amazon confirms shipment, ensuring your financial reporting aligns with actual shipping events. Monitoring is included to catch SKU mismatches or failed settlement imports early, maintaining data integrity during high-volume periods.
Securing data flow through accredited platforms
Leveraging IPaaS with ISO 27001 and SOC 2 and above security accreditations enables secure, efficient integration between Amazon FBA, Inventory Management, and Marketplaces. This approach simplifies connecting Amazon FBA with Inventory Management tools like Inventory Planner, supporting accurate stock control across Marketplaces. IPaaS platforms ensure data protection, reduce manual errors, and provide a centralised, scalable solution for Inventory Management, making operations more reliable and secure.
Surfacing stock discrepancies and settlement exceptions
Standard dashboards often confirm a sync is running without validating the underlying data. We focus on identifying exceptions, such as when FBA stock levels diverge from your inventory system or a settlement does not match the expected order total. Instead of monitoring logs, the system surfaces these discrepancies, distinguishing between temporary API delays and fundamental data mismatches. This prevents stock and financial errors from compounding before they are noticed.
Handing over the operational sync logic
Post-launch, your finance and operations teams must own the logic of the Amazon FBA and Inventory Management sync. We hand over an operating model that defines where inventory truth sits and how to handle FBA stock adjustments. Training covers daily checks for sync errors and how to interpret alerts from the integration layer. Our documentation is an operational reference for the people running the business, not a technical archive. It ensures every exception type has a clear owner, allowing your team to maintain stock accuracy without constant external support.
Maintaining data integrity after go live
Support focuses on maintaining the integrity of the sync after launch. We monitor the data flow between FBA and your inventory system for drift and settlement failures. When an exception occurs, such as a misaligned stock record, we provide the context to resolve it. Our support model includes proactive monitoring and a clear escalation path for issues, ensuring your team avoids debugging logs during peak trading. We look after the health of the integration so your team can focus on replenishment and sales.
Common failures
Reserved stock and stockout triggers
Operational impact: Amazon FBA stock levels often include units in 'Reserved' status that are being moved between fulfilment centres. If these are not isolated, the inventory system may report units as available that cannot be shipped, or conversely, trigger reorder alerts for stock that is already in the network.
Prevention: The integration should use specific FBA inventory reports to isolate sellable quantities. Logic must be defined to handle reserved stock correctly, ensuring the inventory management system only acts on units available for immediate sale.
Settlement reconciliation gaps
Operational impact: Without a clear mapping of Amazon's complex fee structure, finance teams cannot accurately reconcile payouts against sales orders. This results in unexplained variances at month-end and a distorted view of per-SKU profitability.
Prevention: Design the integration to ingest Amazon Settlement Reports, mapping fees and reimbursements to the correct accounts. This ensures that payout journals can be matched against bank deposits with minimal manual intervention.
Multi-channel fulfilment sync errors
Operational impact: When using FBA for other channels, stock deductions can happen at the wrong time if the integration ignores shipment status. This leads to inaccurate stock levels where the system believes an item is shipped before Amazon has actually processed it.
Prevention: Trigger inventory deductions only when Amazon provides a shipment confirmation. This ensures the inventory system stays in step with the physical movement of goods in the FBA warehouse.
Frequently asked questions
My Amazon storage fees are high, but I also stock out. How does integration help?
This happens when your planning system relies on stale inventory data. By syncing sellable stock levels accurately, you can set precise reorder points. This prevents overstocking products that incur high storage fees while ensuring your best-sellers are replenished before they stock out.
Can the integration handle a hybrid (FBA and local warehouse) model?
Yes. The integration distinguishes between FBA-fulfilled and Merchant-fulfilled orders. This ensures that FBA sales do not incorrectly deduct stock from your own warehouse records, keeping inventory levels accurate across all locations.
What is the source of truth for inventory?
Amazon FBA is the source of truth for physical stock quantity at that location. Your inventory management system is the source of truth for planning and purchasing. The integration ensures FBA stock levels are reflected in the IMS so you can make centralised decisions on procurement.
How do we handle Amazon's fees in our financial records?
The integration retrieves Amazon Settlement Reports and pushes them into your central system. This allows your finance team to reconcile fees, storage charges, and refunds against each payout, reducing the manual work required for the month-end close.
