Solution Design
Our design for Amazon FBA and Centra prioritises Centra as the source for product data, while Amazon FBA manages inventory availability for marketplace sales. We typically sequence inventory synchronisation first to protect against stockouts, followed by automated order routing. A common trade-off involves sync frequency. High-frequency updates protect against overselling during peak trade but increase system activity compared to scheduled intervals. We often suggest batching financial data from FBA settlements to simplify reconciliation against marketplace fees and tax records. This approach ensures the ecommerce team monitors stock accurately in Centra while finance maintains control over marketplace performance data, reducing the manual effort required to align marketplace turnover with your primary platform.
Mapping SKU data and order routing
Centra acts as the primary platform for product data, while Amazon FBA manages the physical fulfilment and inventory visibility for marketplace sales. Orders typically flow from Amazon into Centra to maintain a unified sales history, while FBA inventory levels are synchronised back to Centra to protect stock availability on other channels. We apply SKU mapping rules to ensure Amazon listings align with Centra items, preventing routing errors. Monitoring is embedded to catch failed stock updates or orphaned orders before they cause oversells. This sequencing ensures that both systems stay synchronised.
Infrastructure for secure marketplace orchestration
Leveraging IPaaS with ISO 27001 and SOC 2 and above security accreditations enables secure, efficient integration between Amazon FBA, Centra, Marketplaces, and Ecommerce platforms. This approach simplifies connecting Amazon FBA and Centra to Marketplaces and Ecommerce systems, ensuring data protection and compliance. IPaaS platforms offer centralised management, automation, and scalability, making integrations more reliable and secure for businesses operating across Centra, Amazon FBA, and multiple Marketplaces and Ecommerce channels.
Surfacing data drift and reconciliation errors
Dashboards often mask the drift that occurs when Amazon FBA inventory levels and Centra order records slowly diverge. We focus on visibility that surfaces these discrepancies before they hit your month-end reconciliation. Instead of monitoring simple uptime, we track the integrity of data moving between the systems, flagging SKU mapping failures or missed FBA inventory updates. This prevents hidden errors from compounding into stockouts or fulfilment delays. By surfacing specific data mismatches, your team can resolve individual routing issues before they erode the accuracy of your global stock levels or sales reporting.
Operational handover and exception management protocols
We hand over a functional operating model to your finance, operations, and ecommerce teams. Training focuses on practical ownership: ecommerce teams manage product data consistency, while operations monitor FBA stock levels and fulfilment status. Finance teams learn to reconcile marketplace settlements against orders to identify gaps. We define who owns specific exceptions, such as inventory sync failures or SKU mapping errors, so your team can act on alerts effectively. Documentation is provided as a plain-English operational reference detailing daily and weekly checks. It functions as a manual for running the business rather than a technical archive.
Maintaining data integrity after go live
Post-launch, we provide operational support to ensure the Amazon FBA and Centra sync remains accurate. This involves monitoring for sync exceptions and resolving mapping errors that would otherwise halt order flow. We take ownership of the integration performance, focusing on the integrity of inventory levels and order status updates. Our support approach is designed to catch failed inventory pulls or settlement mismatches before they impact your finance reporting. We prioritise the stability of the data flow so your team can focus on marketplace growth rather than troubleshooting technical gaps.
Common failures
Inventory latency and overselling
Operational impact: Amazon FBA inventory levels are not reflected quickly enough in Centra, leading to overselling on the primary ecommerce site. This creates poor customer experiences, increases the CX team workload handling order cancellations, and distorts demand forecasting. The finance team also struggles to reconcile revenue against cancelled sales orders.
Prevention / Action: Design the integration to sync inventory from Amazon to Centra on a frequent, defined schedule. The logic must consume the correct FBA stock figure, often the "AFN Fulfillable Quantity". A stock buffer configured within Centra for FBA-shared SKUs can provide a safety margin against race conditions and sync delays.
Mismatched product data between platforms
Operational impact: Orders captured in Centra fail to generate FBA fulfilment orders because the SKU passed to Amazon does not match an active FBA listing. This stalls the entire fulfilment process for that order, requiring the operations team to manually investigate and correct the SKU in either Centra or Amazon Seller Central, causing dispatch delays.
Prevention / Action: Centra should be designated as the master data source for SKUs and core product information. The integration process must ensure that any new item or variant created in Centra is correctly mapped to a corresponding MerchantSKU in Amazon. Implement exception handling that flags any order failing due to an "InvalidSKU" error for immediate review.
Incomplete financial reconciliation
Operational impact: The finance team cannot reconcile Amazon payouts with the gross value of Centra sales orders because of complex FBA fees, storage charges, and other variable costs. This makes accurate profitability analysis at a SKU or order level impossible. It also creates significant workload during month-end close when attempting to match bulk payouts to individual sales.
Prevention / Action: The integration architecture must treat Amazon Settlement Reports as the definitive source for financial reconciliation data. The process should automatically parse these reports, map Amazon Order IDs back to the original Centra orders, and generate corresponding records (like journals or invoices) to account for all fees. This provides the finance team with the necessary data trail.
Order routing and fulfilment errors
Operational impact: Sales orders from Centra intended for a different fulfilment method (e.g. merchant-fulfilled) are incorrectly pushed to Amazon FBA. Amazon's API rejects these orders, causing them to become stuck in a pending state. This delays fulfilment until an operations team member manually intervenes to investigate the routing error and resubmit the Sales Order to the correct fulfilment service.
Prevention / Action: The integration logic needs to be explicitly designed to differentiate orders based on their fulfilment type, typically by mapping Centra's "Shipping Method" to a specific fulfilment route. Order processing queues should be segregated for FBA and non-FBA-bound orders. Implement specific monitoring to catch and alert on any order rejection from the FBA API.
Frequently asked questions
How do we ensure FBA inventory levels are correctly reflected in Centra to prevent overselling on our website?
The integration treats Amazon FBA's inventory as a distinct stock location synchronised to Centra. Stock levels for FBA-managed SKUs are updated in Centra based on data from Amazon, preventing your direct-to-consumer channel from selling stock that is reserved for marketplace orders. This avoids overselling and subsequent fulfilment failures.
What happens if our product SKUs in Centra don't perfectly match the Merchant SKUs in Amazon FBA?
Mismatched SKUs are a primary cause of integration failure, blocking both stock sync and order processing. The integration depends on a clean mapping between the Centra item record and the Amazon Merchant SKU. If they do not align, sales orders from Centra will fail to create fulfilments in Amazon FBA, causing delays that require manual correction.
How does the integration handle financial reconciliation for Amazon sales and fees at month-end?
To support the finance team's month-end close, the integration uses the Amazon Settlement Report as the single source of truth for financials. This report, which itemises sales, FBA fees, and other charges, is used to generate corresponding journal entries against the original sales orders from Centra. This provides clear traceability from the initial order to the final payout.
We use FBA for some products but fulfil others ourselves. How are orders routed correctly?
The integration correctly distinguishes between fulfilment types by reading product-level data in Centra. This ensures that only sales orders containing FBA-designated items are sent to Amazon FBA for fulfilment. Any orders for merchant-fulfilled products are kept within Centra for your own warehouse teams to process, preventing incorrect order routing.
