A wholesale scanner, or Amazon bulk analysis tool, matches every line of a supplier price list to its Amazon listing and calculates profit, ROI, sales and risk for the whole file at once. This guide compares the three main ones as of October 2026: Seller Assistant’s Price List Analyzer (our product), Scan Unlimited and Analyzer.Tools. They differ most in price, file limits, marketplaces, and what you can do with the results after the scan.
The short list
- Price List Analyzer by Seller Assistant: for wholesale sellers who want the scan, a restriction check on their own seller account and the purchase order in one tool. From $29.99/month.
- Scan Unlimited: for a free start. The free plan scans 1 file a month with up to 10,000 products.
- Analyzer.Tools: for the most price and rank history per product, and for short passes from $15 for 2 days.
How many lines in a supplier price list are worth buying?
About 41 of every 1,000 supplier lines are real leads, according to Seller Assistant’s State of Amazon Wholesale, Q3 2026. The report uses 13.5 million supplier lines that 782 wholesale sellers uploaded for Amazon.com between July 2025 and August 2026. Its headline numbers come from the 4.6 million lines of the 100 sellers who scan regularly.
A lead in the report passes four checks: the Amazon listing can be checked, it gives 20% to 200% ROI on the Buy Box price after Amazon fees, it sells at least 5 units a month (estimated), and Amazon does not hold the Buy Box. Of 1,000 supplier lines:
| Step | Lines left |
|---|---|
| Find an Amazon match | 748 |
| Have a supplier cost and a Buy Box price | 482 |
| Can be checked (fees known, not a multipack or set listing) | 363 |
| Are profitable | 153 |
| Give 20% ROI or more | 100 |
| Also sell 5 or more units a month | 50 |
| Amazon does not hold the Buy Box (leads) | 41 |
To find 41 leads by hand, you would look up 959 lines that you will not buy. After the ROI check, the sales check removes half of the lines with 20% ROI or more, so set a sales filter as well as an ROI filter. The same report finds an IP-risk flag on about 3 in 10 products in supplier price lists, so plan the restriction check and the brand check as part of the same review.
How we compared the tools
We checked each vendor’s own website on October 16, 2026, and compared the tools on the same criteria:
- Price and free plan or trial, as of October 2026
- File and row limits
- Amazon marketplaces
- Matching and profit math: identifiers, multipacks, fees and VAT
- Restriction and IP checks
- What you can do with the results after the scan
Seller Assistant is our product. For the other tools, we describe what their own sites state. Vendors change prices often, so check the pricing page before you buy. For a feature-by-feature look at three of these tools, see best Amazon price list analyzers.
Price List Analyzer by Seller Assistant
Price List Analyzer is the bulk analysis tool in Seller Assistant. You choose the Amazon marketplace, upload an .xlsx or .xls price list, and confirm the columns: identifier, cost of goods, supplier SKU and case quantity. Then you set the price type to Each or Case. For a case price with a case quantity, the unit cost is the case price divided by that quantity. Every identifier is matched to Amazon and enriched with 120+ data points.
Profit, ROI, margin, break-even price and maximum cost of goods are calculated for FBA and FBM. You set inbound shipping, prep, 3PL costs and VAT, and choose whether profit uses the current Buy Box price or the 30, 90 or 180-day average. Matching Rules let you always or never match an identifier to a given ASIN. You can check restrictions in bulk on your own seller account, for the full list or a selection, and the results appear in the table. Saved views keep your columns and filters for the next price list.
Upload your own supplier price list and see what you can sell.
When the shortlist is ready, you select the products and create a purchase order for that supplier. Cost, SKU and case quantity carry over from the price list. Each upload also adds products and offers to the supplier’s record, and you can reanalyze a list with fresh data without uploading the file again.
Turn your next supplier price list into a purchase order.

What is a wholesale scanner for Amazon?
A wholesale scanner matches every line of a supplier price list to its Amazon listing by UPC, EAN or ASIN and calculates profit, ROI, estimated sales and risk for the whole file at once. You then filter the results to the products worth buying instead of checking each line by hand.

How many products in a supplier price list are profitable on Amazon?
About 41 of every 1,000 supplier lines are real leads, according to Seller Assistant’s State of Amazon Wholesale, Q3 2026. A lead gives 20% ROI or more, sells at least 5 units a month, and Amazon does not hold the Buy Box.
