Amazon Seller Central and Cin7 Core
Integration Agency & Consultants
Reconciliation debt usually becomes unmanageable the moment a brand expands into new Amazon regions or moves to FBA. At low volumes, manual spreadsheet uploads can mask the gap between Amazon payouts and your ERP ledger, but scale makes these imbalances permanent. We connect Amazon Seller Central and Cin7 Core so that fees and tax components are correctly mapped to your account codes. This ensures that the transactional engine of Amazon remains in step with the financial source of truth in Cin7 Core, protecting your margin from undetected operational drift.

Solution Design
For Amazon Seller Central and Cin7 Core, we typically treat Cin7 Core as the financial source of truth and inventory master. Design decisions prioritise settlement reconciliation, often batching Amazon reports to map fees and storage costs directly to Cin7 account codes. This approach involves a trade-off where intra-day reporting may lag behind real-time Amazon activity to ensure the final accounting ledger matches actual payouts. We often prioritise FBA inventory mapping to maintain stock accuracy before enabling full order sync. Depending on the operating model, certain complex tax adjustments may remain manual at launch to ensure accuracy. This design ensures finance can close the month with confidence while operations use Cin7 to manage consolidated stock levels across multiple Amazon regions and fulfilment methods.
Mapping transactional data to accounting ledgers
The integration establishes Cin7 Core as the financial source of truth while Amazon Seller Central acts as the transactional front-end. Orders and settlement reports flow from Amazon on a defined schedule, where various fees and marketplace charges are mapped to Cin7 account codes. To maintain data integrity, the system manages FBA stock transfers and VAT liabilities, ensuring inventory depletion matches actual marketplace movement. By monitoring these flows, we identify where the Amazon payout diverges from the expected ledger values, resolving ownership ambiguity before it reaches your accounting software.
Secure orchestration and data compliance standards
Leveraging IPaaS with ISO 27001 and SOC 2 and above security accreditations enables secure, efficient integration between Amazon Seller Central, Cin7 Core, Marketplaces, and ERP systems. IPaaS simplifies connecting Amazon Seller Central and Cin7 Core to Marketplaces and ERP platforms, ensuring data integrity and compliance. The benefits include centralised management, robust security, and reliable automation, making integrations straightforward and secure for businesses handling sensitive data.
Monitoring settlement gaps and tax discrepancies
Dashboards confirm that data moved, but they rarely signal if the data arrived correctly. For Amazon merchants, hidden issues usually dwell in the gap between a settlement import and a reconciled bank statement. Our approach goes beyond simple sync logs to surface specific exceptions, such as missing fees or misaligned tax on cross-border FBA sales. By identifying these discrepancies early, we prevent compounding errors that would otherwise require forensic accounting. Real visibility is knowing that every transaction from Amazon is accounted for in your Cin7 inventory and ledger.
Defining operational and financial ownership boundaries
Successful adoption requires clear ownership boundaries across finance and operations. Finance teams take ownership of settlement reconciliation, typically checking that Amazon payouts match the Cin7 ledger on a defined cadence. Operations teams manage inventory accuracy, specifically monitoring FBA stock movements and SKU mapping for new listings. We hand over an operational manual that details the data flow between systems and how to interpret sync alerts. This documentation is a practical reference for managing exceptions rather than a technical archive. Training ensures that ecommerce and warehouse teams recognise Cin7 Core as the authority for product costs and stock levels.
Maintaining integrity of payouts and stock
Support focuses on maintaining the financial trust boundary between Amazon and your ledger. We monitor the health of the Cin7 Core sync to detect settlement gaps or inventory drift before they impact month-end reporting. When operational issues occurs, such as updated Amazon fee structures or FBA stock transfer discrepancies, we provide diagnosis and resolution based on agreed protocols. This monitoring ensures that finance and operations teams remain focused on trading while the integrity of product costs and VAT liabilities is protected against silent sync failures.
Common failures
Unreconciled Amazon settlement reports
Operational impact: The finance team cannot complete the month-end close because Amazon's net payout does not match the revenue and fees recorded in Cin7 Core. Unmapped FBA fees, advertising costs, and disposal charges create a persistent variance between the bank deposit and the general ledger, requiring days of manual analysis to trace and resolve.
Prevention / Action: The integration must be designed to fetch raw Amazon Settlement Reports before attempting to match transactions. Each fee type and tax component from the report needs to be mapped to a specific general ledger account in Cin7 during implementation. Establish a clearing account process to manage timing differences and an exception queue for any new or unmapped fee types Amazon introduces.
Incorrect cost of goods sold for FBA stock
Operational impact: Profitability reporting in Cin7 Core becomes unreliable because the full landed cost of inventory sent to FBA is not captured. Inbound shipping, customs duty, and FBA prep fees are often missed, which deflates the Cost of Goods Sold (COGS) and gives commercial teams a misleading picture of SKU and channel margin.
Prevention / Action: Use Cin7 Core as the master for the standard cost of each product. The accompanying operational process must apply additional landed costs to the specific purchase orders or warehouse transfers destined for Amazon fulfilment centres. This ensures that when the FBA Sales Order is processed, the COGS journal created in Cin7 Core accurately reflects the true cost of that sale.
Inventory latency and overselling
Operational impact: Delays in syncing FBA stock levels to Cin7 Core lead to an inaccurate view of company-wide inventory, disrupting replenishment and forecasting for other sales channels. When stock syncs are slow, the operations team cannot trust the inventory data, leading to reactive purchase orders and the risk of overselling on one channel while holding excess stock in another.
Prevention / Action: Source-of-truth ownership for inventory must be clearly defined for FBA and non-FBA stock. If Cin7 Core is the master, the integration must push frequent updates to Amazon, respecting API rate limits. If FBA is the master for its own stock, the integration must poll Amazon's inventory reports on a short, defined schedule, with Cin7 Core configured to treat FBA as a distinct warehouse location.
Delayed FBA despatch notifications
Operational impact: When Amazon FBA despatch confirmations fail to promptly create an Item Fulfilment record in Cin7 Core, inventory is not depleted correctly and revenue recognition is stalled. The customer service team lacks visibility on true order status, and finance cannot recognise revenue until the Cin7 Sales Order is marked complete, creating a lag in the order-to-cash cycle.
Prevention / Action: The integration logic must poll for Amazon shipment statuses on a frequent, scheduled basis using the MerchantOrderID as the unique identifier. A retry strategy should be implemented to handle transient API failures from Amazon. Design a daily exception report to flag any Amazon orders shipped more than 24 hours prior that do not have a corresponding Item Fulfilment in Cin7 Core.
Frequently asked questions
Why does the Amazon payout that hits my bank not match the sales total in Cin7 Core?
The payout from Amazon Seller Central is a net figure after various fees, refunds, and held reserves are deducted, so it will rarely match gross sales. A common failure is not mapping all Amazon transaction types to the right accounts, causing a permanent reconciliation gap in Cin7 Core. A correct integration creates a detailed journal entry in Cin7 Core for each settlement, itemising all deductions for an accurate financial picture.
If Amazon FBA loses my stock, how do I update my inventory in Cin7 Core?
Amazon FBA issues reimbursement transactions for lost or damaged stock, but these do not automatically create an inventory adjustment in your ERP. Without a specific workflow, your stock levels in Cin7 Core become inaccurate, risking overselling on other channels. These FBA reimbursement reports must be used to trigger a corresponding inventory write-off in Cin7 Core to maintain an accurate stock valuation.
How are non-standard Amazon fees like returns or disposals accounted for in Cin7 Core?
Amazon settlement reports contain many transaction types for costs like FBA disposal fees, returns processing, and reimbursements which standard connectors can misinterpret. These must be mapped to the correct general ledger accounts in Cin7 Core to avoid a suspense account full of unrecognised costs. A proper integration allows the finance team to map each Amazon fee type to a specific account, enabling an accurate month-end close.
Can I build a single customer view in Cin7 Core if some of my orders come from Amazon?
This is a common operational challenge because Amazon Seller Central provides obfuscated email addresses for privacy, which prevents matching customers by email. Relying on this data creates duplicate customer records in Cin7 Core for anyone who makes a repeat purchase. The operating model must therefore use other details, like name and postcode, to identify and merge customer records, which often requires a secondary process.
