Amazon + NetSuite Integration | Marketplace Connector

Amazon NetSuite integration: orders, FBA inventory and reconciliation

Selling on Amazon while running your business on NetSuite creates a data challenge: orders, inventory, fulfillment, and financial data need to flow seamlessly between Amazon Seller Central and your ERP.

At BrokenRubik, we build Amazon-NetSuite integrations that handle everything from basic order sync to complex multi-channel FBA operations. Whether you sell through Seller Central, Vendor Central, or both, we connect it to NetSuite.

What We Build

Order Management: Amazon orders automatically create sales orders in NetSuite with correct item mapping, pricing, tax, and shipping details. FBA and merchant-fulfilled orders are handled differently based on your fulfillment model.

Inventory Sync: Real-time inventory updates from NetSuite push to Amazon, preventing overselling. For FBA sellers, we sync both FBA warehouse quantities and merchant-fulfilled stock levels.

Amazon FBA Integration: FBA shipments, inbound transfers, and multi-channel fulfillment orders sync with NetSuite. FBA fees, storage charges, and reimbursements map to the correct GL accounts for accurate profitability reporting.

Financial Reconciliation: Amazon settlement reports reconcile against NetSuite transactions. Marketplace fees, refunds, chargebacks, and advertising costs post to the right accounts automatically.

Multi-Marketplace Support: Selling on Amazon US, EU, and other regions? We handle multi-currency transactions, regional tax requirements, and marketplace-specific business rules.

Technical Approach

We integrate Amazon using the SP-API (Selling Partner API) combined with NetSuite's SuiteTalk or RESTlet APIs. Common middleware options include:

• Celigo with pre-built Amazon flows for faster deployment
• Custom Node.js/n8n for specific business logic requirements
• Native SuiteScript for companies wanting everything inside NetSuite
