Connecting Amazon to your ERP system: the complete guide
Here's how to connect your ERP system with Amazon so that inventory, orders, and product data run automatically. This guide takes you through every step, from preparation to go-live.

Amazon is a central sales channel for many retailers. Connecting your ERP system properly saves time every day: stock levels update automatically, orders flow directly into your ERP, and manual data entry is eliminated. This guide shows you how to get from preparation to go-live in six steps.
In brief
An Amazon integration connects your ERP system to Amazon Seller Central via the Amazon Selling Partner API. Stock levels, prices, and product data are automatically transferred to Amazon, and incoming orders flow back into your ERP. In practice, a middleware handles this synchronisation, so you manage Amazon, your POS, and additional channels from a single system.
1. Preparation: What You Need
Before you begin the technical setup, make sure you meet the following requirements:
- Amazon Seller Account: A professional seller account (€39/month) is required.
- ERP System: Your ERP system should offer an interface (API) or export function.
- EAN/GTIN Numbers: Valid barcodes are required for most product categories.
- Product images: Amazon has strict image guidelines (min. 1000x1000 pixels, white background).
- Product Descriptions: Well-structured copy with relevant keywords.
Tip
Check in advance which categories you want to sell in. Some categories (e.g. food, electronics) require approval from Amazon.
2. Setting Up Amazon Seller Central
If you don't have an Amazon Seller account yet:
- Go to sellercentral.amazon.de and click "Register"
- Select "Professional Seller" (required for automated integrations)
- Have ready: business registration, ID document, bank details, credit card
- Complete the verification process (this may take a few days)
- Set up your shipping settings and return policies
3. Choosing the Right Middleware
A middleware connects your ERP system to Amazon and automates data exchange. When choosing one, pay attention to:
- ERP Compatibility: Is your system supported?
- Real-time synchronization: Stock levels should be updated in real time.
- Automatic order import: Orders must flow automatically into your ERP.
- Support: Are personal contacts available when issues arise?

4. Preparing Product Data
Amazon places high demands on product data. Prepare the following information:
Required Fields for Amazon:
- ✓ Product title (max. 200 characters)
- ✓ EAN/GTIN or UPC
- ✓ Brand
- ✓ Manufacturer
- ✓ Product category
- ✓ Price
- ✓ Stock
- ✓ At least one product image
- ✓ Bullet points (5 recommended)
- ✓ Product description
Image Requirements
- Minimum size: 1000 x 1000 pixels (for zoom function)
- Main image: white background (RGB 255,255,255)
- Product must fill at least 85% of the image
- No watermarks, logos, or text in the main image
- Formats: JPEG, PNG, GIF, or TIFF
5. Setting Up the Integration
The typical process for an Amazon integration:
-
Set Up API Access
In Seller Central, go to Settings > User Permissions and create a developer access account. -
Configure Middleware
Enter the access credentials in your middleware and test the connection. -
Set Up Product Mapping
Define which ERP fields are mapped to which Amazon attributes. -
Upload Test Products
Test with a small number of products before transferring your entire assortment. -
Test Order Import
Place a test order and verify that it arrives correctly in your ERP.
6. Go-Live and First Steps
After successful tests, you can go live:
- Upload your complete assortment (in batches, not all at once)
- Activate stock synchronisation
- Set order import to automatic
- Monitor closely during the first few days
Best Practice
Start with a small product selection and expand gradually. This lets you identify and resolve issues early, before they affect your entire assortment.
Common Problems and Solutions
Problem: Products are not being listed
Common cause: missing or invalid EAN numbers. Check whether your GTINs are registered with GS1.
Problem: Orders are not arriving in the ERP
Check the API permissions and make sure your middleware retrieves orders regularly.
Problem: Stock levels do not match
Activate real-time synchronisation and check whether other sales channels are also connected.
Conclusion
A successful Amazon integration comes down to three things: clean product data, a middleware that supports your ERP, and a structured go-live in batches. Once in place, stock levels and orders sync automatically, and you manage Amazon from the system you already use.
