What WalSeller Pro Does

WalSeller Pro is a software service operated by Tukribish LLC that helps online retail sellers research products, calculate profitability, and create and manage marketplace listings across Walmart, eBay, and other major marketplaces. It is delivered as a Chrome extension and a connected web application.

Product Research & Profitability Analysis

Sellers analyze a product to see real-time pricing, estimated monthly sales, marketplace referral and fulfillment fees, ROI, and break-even price — so they can decide whether an item is worth sourcing before they list it.

Marketplace Catalog & Listing Management

With the seller's authorization, WalSeller Pro connects to the seller's own marketplace account through the marketplace's official API to retrieve catalog and listing data, analyze fees and competition, and help the seller create and update their own product listings.

Cross-Marketplace Listing

Sellers can take a sourced product and create listings on the marketplaces they sell on — including Walmart, eBay, and other major marketplaces — with assisted title, description, category, and pricing fields to reduce manual data entry.

Fee & Margin Calculation

Automatic, category-aware fee detection (referral fees, fulfillment fees) combined with the seller's cost of goods produces accurate net profit, margin, and ROI for every product.

Bulk Analysis

Sellers upload a list of products and analyze hundreds of items at once, making it practical to evaluate full wholesale catalogs for profitable opportunities.

Secure, Authorized Access

WalSeller Pro only accesses a seller's marketplace account after the seller explicitly authorizes the connection, uses that access solely to provide the features above, and never sells seller data. See our Privacy Policy for full details on how data is collected, used, stored, and deleted.

Marketplace Seller Suite

Tools for Marketplace Sellers

When a seller connects their own marketplace seller account, WalSeller Pro uses the marketplace's official API — with the seller's explicit authorization — to provide the following services on the seller's own account:

Listing & Catalog Management

Check listing eligibility and category restrictions for products before sourcing them, then create and update product listings on the seller's own account — titles, descriptions, attributes, and offers.

Pricing Tools

Retrieve competitive pricing data for the seller's ASINs and provide pricing recommendations so sellers can price competitively while protecting their margins.

Fulfillment Program Management

Analyze marketplace fulfillment fees for the seller's products, compare fulfillment programs against other options, and support inbound shipment planning to fulfillment centers.

Account Performance Insights

Give sellers a clear overview of their seller account — marketplace participation, account health, and performance signals — alongside their other marketplace accounts in one dashboard.

Finance & Profit Reports

Turn settlement and transaction data into readable profit reports — revenue, fees, refunds, and net proceeds — combined with the seller's tracked expenses for true per-product profitability.

Inventory & Order Tracking

Monitor stock levels across the seller's listings, surface restock alerts before items sell out, and track order volume and status without leaving WalSeller Pro.

Upstream Warehouse Visibility

For sellers using upstream warehousing and distribution programs, view upstream inventory and shipment status so incoming stock is visible next to fulfillment-center inventory.

Brand Search Insights

For brand-registered sellers, surface search-term and sales insights to guide product and keyword decisions.
