Product Management
Updated March 2026
The Products section is where you manage your entire catalog. All items are imported automatically from your connected store — you don’t need to add products manually. When you update a product in your store (price, stock, description), the changes are synced to Mastersel automatically through your integration.
Product Information
Each product in your catalog displays the following information:
| Field | Description |
|---|---|
| Category | Product category from your store (must be mapped to a Mastersel category) |
| Brand | Product brand name — used for marketplace listing optimization |
| SKU | Your unique product identifier — stays consistent across all systems |
| Quantity | Current stock count synced from your store |
| Price | Your base selling price — the amount you receive per sale |
| EAN | European Article Number (barcode) — required for marketplace listing |
Product Requirements
Every product must meet these minimum requirements before it can be activated for marketplace distribution:
- Valid EAN barcode — required by all major marketplaces for product identification
- Product weight — needed for accurate shipping cost calculation and label generation. If individual product weights are not available, you can set a default weight per category in the category mapping system
- At least one product image — high-quality images significantly improve conversion rates
- Product title — clear and descriptive, following marketplace best practices
- Product price — your base price, which you’ll receive in full for each sale
Product Activation
Products that meet all requirements (EAN, weight, mapped category, image, price) are automatically activated and become eligible for marketplace distribution immediately. There is no manual activation step — once a product has all the required data, it goes live automatically.
If a product is not yet active, it means it is missing one or more required fields. Check the product details in your dashboard to see what data needs to be completed.
Deactivating Products
If you need to temporarily stop selling a product (seasonal item, low stock, quality issue), you can deactivate it at any time. The product stays in your catalog and can be reactivated later. Deactivation removes the product from marketplace listings but doesn’t delete any data.
