Overview
Profit calculator for Amazon and Walmart sellers: fees, margin and offers on every product page. Free during early access.
Free during early access, requires an email. SellerUtility shows the numbers an Amazon or Walmart reseller needs on the product page they are already looking at: fees, profit, margin and ROI, and the offers on the page. Profit on the product page • Enter your buy cost and see referral fee, fulfillment fee, profit, margin and ROI at once, from the published US rate cards. • FBA, FBM, WFS or seller-fulfilled. • When an Amazon page shows no price, the panel fills in a reference price (lowest new offer or Buy Box, with its date) from the SellerUtility catalogue or Keepa. To do this it sends that product's ASIN and marketplace to SellerUtility. • The cost field accepts a dot or a comma and simple math such as 15.00 * 0.85, for supplier prices with a discount. • Show prices in your currency, using the European Central Bank's daily reference rates. Offers on the page • Every offer on the product with fulfillment type and price, loaded by your browser from the marketplace itself. • Walmart items: available stock per seller, the sales badge and review summary, and the item's price, seller and review history as other users of the extension saw it. Optional: turn on "Help build the shared product catalogue" in Settings to add what your pages show. • Seller storefront: start an analysis on a Walmart seller's page and your browser reads that seller's public storefront. Sourcing from supplier sites • On a supplier site, click "Turn on for this site": the extension reads product barcodes on that site only (UPC, EAN, ISBN, GTIN, checksum-validated). Save to your own Google Sheet (optional) • Send the product, with the status, quantity, supplier, code, source URL and note you type in the panel, to a tab of your own Google Sheet. • SellerUtility opens only the spreadsheets you pick for it: you choose the file in Google's own file picker on sellerutility.com/sheets/connect. It cannot see the rest of your Google Drive. Getting started • Enter your email on sellerutility.com when the panel asks; the tools unlock right away. We send only the confirmation email, and launch news only if you tick that box on the form. • Tools shown as "Pro - Coming soon" in the panel (check restrictions, watchlist, list this product, cross-market match) are not part of this version. Privacy The extension reads the page you are viewing. On a marketplace product page your browser also loads that product's offers, and on an item page its sellers, stock and reviews, from the marketplace itself; these requests go from your browser, not through us. It contains no ads or analytics trackers. It keeps a short list of product pages you opened (Recently viewed), on your device only. Without an account, SellerUtility receives the ID and barcode of each product page you open, for package size, hazmat, the other marketplace's match and the shared price history, and the ASIN of a product page with no price, for a reference price. They are sent with a free-access key that is not linked to your email. Your email reaches our waitlist through our website. Google Sheets export talks to Google directly and reaches only the spreadsheets you pick.
