Install in a minute

Unzip into a folder you will keep. If that folder is deleted, Chrome removes the extension.
Open chrome://extensions and turn on Developer mode (top right). Chrome may warn about developer-mode extensions. That warning is normal for a manual install.
Click Load unpacked and choose the folder that contains manifest.json — not the zip file.
Open a product page. The panel sits on the side. Pin Sellsavo from the puzzle icon if you want your plan in the toolbar.

This build does not update itself. When a new build is on this page, download it and load the new folder. Chrome Web Store publication is being prepared; after that, updates will be automatic.

Where it works

Amazon in 22 countries, plus eBay, Etsy, Walmart, Mercado Libre, Flipkart, Shopee, Lazada, Trendyol, noon, Takealot, Jumia, Allegro, Kaspi, Yandex Market, Wildberries and Ozon. Landed cost on 1688, Alibaba and Made-in-China. Confidence and dates for every fee table are on Fee data status Ruble rates.

The first calculation

Unit cost — purchase price plus shipping to the warehouse. Without it, profit stays hidden.
Package size — length, width, height and weight, if the page does not show them. Until then the panel shows “—”, not a zero.
Ads and returns — only the percentages you enter. An empty field is not treated as zero.
Estimated, secondary or outdated fees are labeled. Confirm a large order in your seller account. Those labels can never produce a “take” verdict.

What the extension can access

Only supported marketplace and supplier sites. It never runs on checkout, sign-in, account or seller-console pages. Your costs stay in the extension’s local storage. During the free beta it does not contact a payment or licence server.

If the panel does not appear

You are on a product page, not the store homepage, cart, sign-in or seller console.
The extension is enabled at chrome://extensions.
Reload the product page after installing.
