Amazon FBA and Fulfil
Integration Agency & Consultants
This integration becomes necessary when Amazon FBA sales volume makes manual reconciliation and stock tracking across warehouses impossible. When Amazon's reported inventory and your Fulfil ledger diverge, it leads to overselling or delayed replenishment. We connect Amazon FBA to Fulfil to maintain inventory accuracy and financial clarity, ensuring settlement reports are processed without manual data entry and stock levels remain consistent across all channels.
Auditing system gaps across your stack
Cogent2 connects your Amazon FBA and Fulfil integrations with Marketplaces and ERP systems quickly and efficiently. Our consulting services are invaluable, offering a comprehensive systems audit that uncovers inefficiencies and integration gaps across Amazon FBA, Fulfil, Marketplaces, and ERP platforms. This enables our consultants and your team to take decisive action, ensuring your technology ecosystem operates smoothly. With our expertise, you can deliver a consistently excellent customer experience and keep your business running at its best.
Solution Design
We design Amazon FBA and Fulfil integrations with Fulfil as the central source of truth for overall inventory and financial reconciliation. A core design decision involves managing a virtual warehouse in Fulfil to mirror FBA stock levels. We typically favour a batch approach for Amazon Settlement Reports to ensure finance can reconcile fees and taxes accurately, even if this means a slight lag in intra-day reporting. Conversely, Amazon FBA sales orders are sequenced to post into Fulfil once fulfilled to maintain inventory truth. This trade-off ensures the ERP remains the master for procurement and stock replenishment. This architecture allows finance to close books with confidence while ops manages replenishment based on accurate, aggregated demand across all channels.
Mapping data flows and virtual warehouses
The integration establishes Fulfil as the central record for inventory and finance, while Amazon FBA handles fulfilment. Sales orders flow from Amazon into Fulfil to trigger stock reductions in a dedicated virtual warehouse location. By mapping tax details and settlement reports, the system maintains financial accuracy, while monitoring helps detect shipping report delays to prevent duplicate order entries or inaccurate inventory levels.
Orchestrating workflows via secure IPaaS layers
Leveraging IPaaS with ISO 27001 and SOC 2 and above security accreditations enables secure, efficient integration between Amazon FBA, Fulfil, Marketplaces, and ERP systems. This approach simplifies connecting Amazon FBA and Fulfil to Marketplaces and ERP platforms, ensuring data integrity and compliance. IPaaS platforms provide centralised management, robust automation, and secure data handling, making complex integrations straightforward and reliable for businesses operating across multiple systems.
Surfacing settlement discrepancies and stock drift
Standard dashboards often hide the drift that occurs between Amazon's reported stock and your ERP's ledger. We focus on true visibility by identifying orders that failed to post into Fulfil, mismatched SKU mappings, and reconciliation gaps in settlement reports. We surface these errors before they cause financial headaches at month-end. Instead of just seeing that the connection is active, you see exactly which FBA returns haven't been correctly updated in Fulfil, allowing your team to act on discrepancies.
Operational handover for finance and ops
Handover focuses on ensuring finance and operations teams own the Amazon FBA and Fulfil operating model. Finance learns to reconcile Amazon Settlement Reports against Fulfil sales orders, while operations manages FBA replenishment signals and virtual warehouse adjustments. We provide documentation that explains where inventory truth lives and how to interpret sync alerts. Teams are trained to perform daily health checks on order posting and monthly reconciliations of Amazon fees. This is operational guidance for the people running the business, not a technical manual. It ensures your team knows exactly who owns each exception type, from tax registration mismatches to SKU sync errors, before we step back.
Governing data integrity after go live
Post-launch, we provide monitoring to catch failures that standard logs can miss, such as carrier code mismatches or settlement report delays. Our support is focused on operational continuity, helping you manage exceptions and ensuring the sync between Amazon FBA and Fulfil remains stable during high-volume periods. We work to identify and resolve data issues before they affect your fulfilment or financial reporting.
Common failures
Inventory latency and overselling
Operational impact: Fulfil's view of stock availability diverges from the sellable inventory at Amazon's fulfilment centres. This leads to overselling popular SKUs during promotions, causing negative customer experiences and risking Amazon account health. It also corrupts demand planning, as replenishment decisions made by the operations team in Fulfil are based on inaccurate stock level data.
Prevention / Action: The integration must be designed to handle Amazon's detailed inventory states, not just a single availability figure. Logic should be built to correctly interpret and map 'sellable', 'reserved', and 'in-transit' FBA stock to distinct fields or locations within Fulfil. Inventory syncs should run on a frequent, defined schedule, with monitoring to catch significant discrepancies before they result in overselling.
Failure to reconcile Amazon fees and payouts
Operational impact: The finance team receives a net payout from Amazon but cannot automatically match it against the underlying sales orders, returns, and variable FBA fees in Fulfil. This prevents an accurate order-to-cash reconciliation, forcing days of manual work to close the books each month. It obscures the true profitability of the Amazon channel and creates significant audit risk.
Prevention / Action: The integration must be built to retrieve and parse Amazon's Settlement Reports. This process should systematically create records in Fulfil that correspond to each debit and credit on the report, linking them to source orders or posting them to the correct general ledger accounts. An exception handling queue is essential to flag any transactions that cannot be matched automatically for review by the finance team.
Mishandling of FBA vs Merchant-Fulfilled orders
Operational impact: If the integration does not differentiate between orders fulfilled by Amazon (FBA) and those fulfilled by the merchant (FBM), it can cause chaos. FBA orders may incorrectly trigger fulfilment requests from the main warehouse, creating duplicate work and polluting fulfilment data. This confuses operations teams, skews performance metrics, and makes it impossible to get a clean view of which orders require action.
Prevention / Action: At the point of order import, the integration logic must check the 'fulfilment-channel' attribute provided by the Amazon API for every order. Based on this data, the system should route the order accordingly. FBA orders should be created in Fulfil for accounting and demand planning but must be excluded from any process that generates pick lists or outbound shipment records.
