Your Amazon business, one question away
Selin pulls all your Amazon data into one clear dashboard, and lets you connect Claude, ChatGPT, or any MCP client to ask about it in plain language. Built by Amazon sellers.
Built by Amazon sellers
We've sold across European marketplaces for over a decade. Selin is the tool we wanted: honest numbers, fast answers, no guesswork. What started as a profit dashboard has now grown into a data-driven platform for your whole Amazon business: every sale, order, return, fee and FBA movement, consolidated and ready to act on.
See everything about your Amazon business
All your Amazon data in one place.
Sales and Profit
Real profit calculation is the backbone of Selin. Get instant insight into sales performance based on real numbers, and spot both your bestsellers and the products dragging your margin down.
Orders and Returns
See incoming and past orders, with returns woven through the whole system. Analyze the most common return reasons and their true cost - refund fees plus the value of the goods you lose.
Inventory
Manage thousands of products in one place and catch unprofitable ones before you make a single sale. Every number behind the final profit is there: price, tax, fees and COGS.
Listing groups
Build your own groupings to analyze by brand or product category, and keep daily work quick to navigate.
COGS
What your products cost you feeds straight into the final profit calculation. Upload those costs through the COGS Manager or link your XML feed.
FBA Manager
See your day-to-day FBA operations in one view: the restock pipeline, storage costs, inventory health and products recommended for removal.
Shipping
Track shipping revenue and costs in their own section. Selin keeps product and shipping revenue apart, so the product-level analysis stays honest.
Account Health
Get ahead of trouble before it costs you sales. Monitor your account health rating and marketplace status, and handle sale-stoppers like compliance and GPSR.
Notifications
Everything worth knowing reaches you clearly and in time. Stay on top of what is happening and head off listing problems early.
