Frequently Asked Questions
Updated March 2026
How do products appear on marketplaces?
Once a product has all required data and is activated, Mastersel automatically creates optimized listings across connected marketplaces. Products are listed under the Mastersel brand with translated titles and descriptions adapted for each target market.
Do I need my own marketplace accounts?
No. All marketplace listings are managed under the Mastersel brand. You don’t need to register on Amazon, eBay, Allegro, or any other marketplace. You only need your Mastersel seller account.
When do I get paid?
Payout information and schedules are available in the Balance section of your dashboard. Payouts are based on completed and delivered orders, minus any return adjustments for the period.
Can I choose which marketplaces my products appear on?
Mastersel manages marketplace distribution automatically based on product suitability, market demand, and listing requirements. You control which products are active — Mastersel determines the best channels for each product.
Can I deactivate products?
Yes. Products can be activated or deactivated at any time from the Products section. Deactivating a product removes it from marketplace listings but keeps it in your catalog for future reactivation.
Why are some products not eligible for activation?
Products need certain required data before they can be listed on marketplaces. The most common missing fields are: EAN barcode, product weight, category mapping, images, or price. Check the product details to see what’s missing.
How often should I review orders?
We recommend checking for new orders at least twice per day — morning and afternoon. Fast order confirmation leads to faster delivery, which improves customer satisfaction and your seller performance.
What happens if I reject an order?
The order will not move forward in the shipping workflow. Only reject when fulfillment is genuinely impossible (e.g., stock is sold out, product is damaged). Frequent rejections affect your seller performance metrics.
How long does product import take?
Import time depends on your catalog size and integration type. Small catalogs (under 1,000 products) typically import within minutes. Larger catalogs may take a few hours. You can monitor the progress in your dashboard.
Do I handle customer support?
No. Mastersel handles all customer communication, including pre-sale questions, order inquiries, and after-sales support. You never interact with marketplace customers directly.
What currencies are supported?
You set your product prices in your store’s currency. Mastersel handles all currency conversion automatically when listing products on international marketplaces.
