Amazon-Odoo Integration: The Complete 2026 Guide to Automating Your Amazon Business

Selling on Amazon while managing operations in Odoo creates a common problem: data lives in two places. Orders arrive in Seller Central, inventory updates happen in Odoo, and your team spends hours manually reconciling the two. An Amazon-Odoo integration eliminates this gap by creating a real-time bridge between Amazon Seller Central and your Odoo ERP instance.

This guide covers the technical requirements, integration architecture, and step-by-step process for connecting Amazon with Odoo in 2026.

Why Integrate Amazon with Odoo?

Amazon sellers processing more than 50 orders per day face three persistent problems without ERP integration:

1. Inventory overselling — Stock counts drift between Amazon and your warehouse within hours of a busy sales day.
2. Order processing delays — Manually entering Amazon orders into Odoo adds 3-5 minutes per order. At 200 orders/day, that is 10-16 hours of data entry.
3. Financial reconciliation nightmares — Amazon payouts combine sales, returns, fees, and advertising charges into a single settlement. Without automated mapping, monthly reconciliation takes days.

An integrated system solves all three by synchronizing data bidirectionally between Amazon and Odoo in near real-time.

What Data Gets Synchronized?

A properly configured Amazon-Odoo integration handles these data flows:

| Data Type | Direction | Frequency | |---|---|---| | Product listings | Odoo to Amazon | On change | | Inventory levels | Odoo to Amazon | Every 15 minutes | | Orders | Amazon to Odoo | Every 5 minutes | | Shipping confirmations | Odoo to Amazon | On dispatch | | Returns/refunds | Amazon to Odoo | Hourly | | Settlement reports | Amazon to Odoo | Per payout cycle |

How Amazon SP-API Works

Amazon deprecated the MWS API in 2024 and now requires all integrations to use the Selling Partner API (SP-API). Key differences from the old MWS API:

• OAuth 2.0 authentication replaces access keys
• Role-based permissions — you request only the API scopes your integration needs
• Rate limiting is more granular, with per-endpoint throttling
• PII handling requires restricted data tokens for customer information

The ECOSIRE Amazon Store Management module handles SP-API authentication, token refresh, and rate limiting out of the box, so you do not need to build or maintain API infrastructure.

Integration Architecture

The integration follows a hub-and-spoke model with Odoo as the central hub:

Order flow:

1. Customer places order on Amazon
2. SP-API webhook (or polling) detects new order
3. Integration creates Sales Order in Odoo with Amazon order reference
4. Odoo processes order through standard fulfillment workflow
5. When shipped, tracking number pushes back to Amazon via SP-API
6. Amazon updates customer with shipping notification

Inventory flow:

1. Stock move occurs in Odoo (receipt, sale, adjustment, transfer)
2. Integration calculates available-to-sell quantity per Amazon warehouse/FBA location
3. Updated quantities push to Amazon via SP-API Listings feed
4. Amazon updates listing availability within minutes

FBA vs. FBM Considerations

Your fulfillment model affects integration complexity:

Fulfillment by Amazon (FBA):

• Inventory transfers to Amazon warehouses need tracking as inter-warehouse transfers in Odoo
• Amazon handles shipping, so Odoo does not generate delivery orders for FBA items
• FBA fees must be mapped to expense accounts in Odoo Accounting
• Multi-country FBA (Pan-European, NARF) requires location-aware stock tracking

Fulfillment by Merchant (FBM):

• Orders follow standard Odoo fulfillment (pick, pack, ship)
• Carrier integration in Odoo generates tracking numbers
• Buy Shipping API in SP-API can purchase Amazon-discounted labels directly

Most Amazon sellers use a hybrid approach. The ECOSIRE module supports both FBA and FBM workflows within the same Odoo instance, with automatic detection based on the fulfillment channel in each order.

Multi-Marketplace Support

Amazon operates 21 marketplaces across North America, Europe, Asia-Pacific, and the Middle East. If you sell on multiple Amazon marketplaces (e.g., amazon.com, amazon.co.uk, amazon.de), your integration needs to:

• Map each marketplace to the correct Odoo company or warehouse
• Handle currency conversion for pricing and settlement
• Manage VAT/GST registration per country
• Consolidate reporting across all marketplaces into unified dashboards

Settlement Report Reconciliation

Amazon's settlement reports are the most complex part of the integration. A single settlement can contain:

• Product charges (principal, tax, shipping)
• Promotion charges (coupons, Lightning Deals)
• Amazon fees (referral, FBA fulfillment, storage, advertising)
• Adjustments (returns, reimbursements, A-to-Z claims)

Each line item needs to map to the correct account in Odoo's chart of accounts. Automated settlement reconciliation saves accounting teams 15-20 hours per month compared to manual spreadsheet matching.

Step-by-Step Setup Process

Prerequisites

• Odoo 17, 18, or 19 (Community or Enterprise)
• Amazon Professional Seller account
• SP-API developer registration (or use ECOSIRE's pre-registered application)

Installation

1. Install the Amazon Store Management module in your Odoo instance
2. Navigate to Settings and configure your Amazon credentials
3. Authorize the application via Amazon's OAuth flow
4. Map your Amazon marketplace to an Odoo company and warehouse
5. Configure product mapping rules (by SKU, ASIN, or barcode)
6. Enable order synchronization and set your sync frequency
7. Run initial inventory sync to align stock levels

Post-Setup Validation

• Place a test order on Amazon and verify it appears in Odoo within the configured sync interval
• Ship the test order from Odoo and confirm tracking appears in Amazon
• Adjust a stock quantity in Odoo and verify the change reflects on Amazon
• Review a settlement report import and verify account mappings

Common Integration Challenges

Product variant mapping: Amazon uses ASIN/SKU combinations while Odoo uses product templates with variants. Your integration needs a reliable mapping strategy, especially for products with color/size variations.

Rate limiting: SP-API enforces strict rate limits. Bulk operations (price updates, inventory feeds) need to be batched and throttled to avoid 429 errors.

Time zone handling: Amazon timestamps use UTC. Ensure your Odoo instance processes order timestamps correctly to avoid duplicate or missed orders during time zone transitions.

Multi-currency pricing: If you sell on amazon.de in EUR and amazon.com in USD, product prices need marketplace-specific management rather than simple currency conversion.

Performance Benchmarks

With the ECOSIRE Amazon module, typical performance metrics include:

• Order sync latency: Under 5 minutes from Amazon order creation to Odoo Sales Order
• Inventory update speed: 500+ SKU updates per minute via SP-API feeds
• Settlement processing: 10,000+ line items processed in under 2 minutes
• Uptime: 99.9% sync reliability with automatic retry on transient failures

Next Steps

Whether you are launching on Amazon for the first time or optimizing an existing multi-marketplace operation, connecting Amazon to Odoo transforms manual, error-prone processes into automated workflows.
