Amazon FBA and Scend
Integration Agency & Consultants
Operational pressure usually peaks when month-end reports show discrepancies between Amazon FBA orders and Scend fulfilment status. At low volume, these gaps are manageable, but as marketplace sales scale, mismatched inventory levels lead to overselling on secondary channels and missed dispatch windows. We bridge the disconnect between Amazon's sales volume and the physical warehousing processes managed by Scend, ensuring stock accuracy is grounded in reality rather than sync illusion.
Auditing inventory data and system logic
We connect your Amazon FBA and Scend integrations with Marketplaces and WMS/3PL solutions quickly and efficiently. Our consulting services are invaluable, offering in-depth system audits that empower both our consultants and your team to identify and resolve issues across Amazon FBA, Scend, Marketplaces, and WMS/3PL. This ensures your technology ecosystem operates smoothly, supporting reliable fulfilment and customer satisfaction. With actionable insights from our audits, you can confidently deliver a great experience to your customers.
Solution Design
Our design for the Amazon FBA and Scend integration prioritises inventory accuracy and order-to-dispatch speed. We typically establish Scend as the inventory master, pushing available stock levels to Amazon on a defined schedule to prevent overselling. Orders flow from Amazon frequently to ensure dispatch deadlines are met. A significant trade-off involves the inventory sync interval. Frequent updates improve accuracy but can increase system fragility during peak periods, so we often implement a buffered approach to protect against stockouts. Finance typically closes the month using reporting based on Scend fulfilment records, while the ecommerce team monitors Amazon for sales performance. This design ensures that physical stock and digital sales are reconcilable, even when processing high volumes across multiple channels.
Mapping order flows and dispatch signals
The integration treats Scend as the physical inventory master and Amazon FBA as a primary sales channel. After an order is placed, the record flows to Scend for picking and packing. Once dispatched, shipping confirmation and tracking numbers are pushed back to Amazon. Inventory levels are typically updated on a defined schedule, using Scend available stock figures to protect against overselling. This logic accounts for stock already committed to other orders. Built-in monitoring surfaces alerts if order status updates fail, allowing teams to intervene before dispatch deadlines are missed.
Orchestrating workflows via secure middleware platforms
Leveraging IPaaS with ISO 27001 and SOC 2 and above security accreditations enables secure, efficient integration between Amazon FBA, Scend, Marketplaces, and WMS/3PL systems. This approach simplifies connecting Amazon FBA and Scend to Marketplaces and WMS/3PL, ensuring data protection and compliance. IPaaS platforms reduce manual effort, improve reliability, and support scalability, making integrations more robust and secure for businesses handling complex e-commerce operations.
Identifying reconciliation gaps and sync failures
Visibility is about surfacing the discrepancies that hide in the gaps between Amazon and Scend. We monitor for specific failure patterns that dashboards often miss, such as inventory syncs that incorrectly include damaged units in sellable stock counts. If a Scend box dimension exceeds Amazon's inbound limits or a SKU mismatch occurs, the system flags the exception before the shipment is rejected at the dock. This diagnostic approach captures individual record failures before they compound into systemic reconciliation debt.
Handing over the new operating model
The handover focuses on ensuring finance, ops, and ecommerce teams own their parts of the new operating model. Finance learns how to reconcile Amazon payouts against Scend fulfilment records, while ops teams are trained to monitor order flow and respond to SKU-level alerts. We provide operational documentation that explains where data lives and what to check weekly to prevent inventory drift. This documentation is written for the people running the business rather than being a technical archive. Training is anchored in the specific design decisions made during implementation, ensuring your team knows how to manage daily alerts and exceptions.
Managing SKU mapping and warehouse throughput
Ongoing support focuses on preventing operational drift between Amazon Seller Central and the Scend WMS. We take technical ownership of the mapping, ensuring that Scend work orders correctly trigger the required status updates to prevent FBA inbound shipments from expiring. If SKU identifiers shift or shipping dimensions violate receiving rules, our team identifies the cause and resolves the bottleneck. This proactive monitoring protects your Amazon seller rating and maintains warehouse throughput during peak periods.
Common failures
Inventory latency causing overselling
Operational impact: When Scend is used for multi-channel fulfilment, delays in communicating Amazon FBA sales back to Scend mean the central stock pool is not depleted in near real-time. This allows other channels to sell stock that no longer exists, leading to oversold orders. The customer service team must then manage cancellations and the operational team's fulfilment workflow is disrupted by stock-outs on accepted Sales Orders.
Prevention / Action: The integration must treat Scend as the master source of available inventory. Order processing logic should be designed to place an immediate stock reservation in Scend the moment an FBA order is confirmed, even before it is ready for picking. This should be paired with frequent, scheduled reconciliation jobs to audit inventory levels between the two systems, catching any discrepancies that event-based updates miss.
Incorrectly routing Amazon-fulfilled orders to Scend
Operational impact: Mistaking an order fulfilled by Amazon's own network (an 'AFN' order) for a merchant-fulfilled order results in it being sent to Scend for dispatch. This leads to duplicate shipments, creating direct financial loss from wasted stock and shipping costs. It also causes a confusing customer experience and requires significant effort from finance and operations teams to correct inventory and sales records.
Prevention / Action: The integration's order ingestion process must include strict filtering logic. It should be configured to inspect the 'FulfilmentChannel' field on every order from Amazon and only create Sales Orders in Scend for those explicitly marked as 'MFN' (Merchant Fulfilled). A clear exception handling process should alert operational teams if any 'AFN' orders are captured, preventing them from ever reaching the warehouse queue.
Settlement report and fee reconciliation gaps
Operational impact: Amazon's Settlement Reports contain a complex mix of sales revenue, FBA fees, storage charges, and other adjustments. Without an automated breakdown, the finance team must spend days manually matching payouts to the original sales orders and fees. This severely delays the month-end close process and prevents an accurate analysis of SKU and channel profitability.
Prevention / Action: Design the process to automatically ingest and parse the flat file Settlement Reports from Amazon. The integration logic must map each transaction type within the report to the corresponding record in the finance system, using the Amazon Order ID as the key to link back to orders fulfilled via Scend. This requires creating a clear mapping for all possible fees and transaction codes before implementation.
SKU and bundle translation errors
Operational impact: If the Merchant SKU (MSKU) on an Amazon FBA listing does not perfectly match the corresponding product code in Scend, the Sales Order will fail to import. This is especially problematic for bundles or kits, where Amazon has a single parent SKU but Scend must pick multiple component SKUs. These failures stop the automated fulfilment process entirely, requiring manual intervention from the ops team and delaying customer shipments.
Prevention / Action: A central system, like an ERP, should act as the master for product data, not Amazon. The integration itself should contain the business logic to handle bundle translation. When an order for a bundle SKU is received, the integration should replace it with the corresponding component SKUs and quantities before creating the Sales Order in Scend, ensuring the warehouse receives an actionable pick list.
Frequently asked questions
We use both Fulfilled by Amazon (FBA) and Fulfilled by Merchant (FBM). How does the integration route orders correctly to Scend?
The integration must be configured to read the fulfilment channel flag on each order from Amazon. Orders flagged as 'FBA' are ignored, while 'FBM' orders are correctly passed to Scend as Sales Orders for picking. If this logic is wrong, FBM orders will never reach your warehouse, or Scend will attempt to process an order Amazon is already fulfilling.
What happens if our SKUs in Scend don't perfectly match the Merchant SKUs in Amazon Seller Central?
A SKU mismatch is a primary cause of integration failure, stopping the order-to-cash process. If the Merchant SKU on an Amazon order does not find an identical match in Scend, the order will fail to import, preventing fulfilment. This requires manual correction and causes significant shipping delays, which directly impacts your marketplace performance metrics.
How does Amazon get updated once Scend has dispatched an FBM order?
After Scend marks an order as dispatched in its system, the integration sends an Item Fulfilment confirmation back to Amazon FBA. This message contains the shipping carrier and tracking number, automatically marking the order as shipped in Seller Central. If this return synchronisation fails, orders may remain 'unshipped' in Amazon, which harms your account health and prompts customer queries.
Why would some Amazon orders not appear in Scend straight away?
This is often an intentional part of the operating model designed to protect your inventory. The integration should be configured to only import confirmed Amazon orders, ignoring those in a 'Pending' state. This prevents Scend allocating stock from a Sales Order that might later be cancelled by Amazon due to payment failure, ensuring you don't commit stock unnecessarily.
