Amazon + NetSuite Integration | Marketplace Connector

Connect Amazon with NetSuite

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

FAQ

How often does inventory sync between Amazon and NetSuite?

We typically configure inventory sync every 15-30 minutes, though near-real-time sync is possible for high-volume sellers. The right frequency depends on your order volume and risk tolerance for overselling.

Can you handle Amazon FBA and merchant-fulfilled orders differently?

Yes. FBA orders create different fulfillment records in NetSuite than merchant-fulfilled orders. We configure separate workflows, GL account mappings, and fulfillment processes for each channel.

How do you handle Amazon marketplace fees in NetSuite?

Amazon settlement reports are parsed and broken down into individual fee categories (referral fees, FBA fees, advertising, etc.) that map to specific GL accounts in NetSuite. This gives you accurate Amazon profitability reporting.

What about Amazon Vendor Central (1P)?

We also integrate Vendor Central with NetSuite, handling purchase orders from Amazon, ASN (Advanced Shipping Notices), invoicing, and chargeback management.
