Scan a whole supplier list against Amazon
Upload an Excel or CSV file of up to 200,000 products. Wholesale Analyzer matches every UPC, EAN, ASIN or ISBN to its Amazon listing and adds live prices, fees, profit, sales estimates, competition and a BUY, REVIEW or AVOID decision.
A wholesale scanner does one job: it takes the barcodes on a supplier’s price list and tells you what each one is worth on Amazon. The hard part is doing it accurately for thousands of rows, so that one bad match does not make the whole result wrong.
What you can upload
- Files: .xlsx or .csv, up to 200,000 products in one scan.
- Identifiers: UPC, EAN, ASIN or ISBN. You choose the type, and you can name your columns however you like.
- Optional columns: your cost, the supplier’s MOQ, the case pack and your SKU. With a cost, every product gets profit, ROI and a decision.
- Marketplaces: 21 Amazon marketplaces, with results in the marketplace’s currency.
Before you upload, keep barcodes stored as text so Excel does not drop the leading zeros. The supplier file guide lists the columns, and the free UPC and EAN validator finds broken check digits.
What every scanned product gets
The matched listing
UPC or EAN to ASIN, and ASIN to UPC or EAN, shown in the results, with book details such as binding and edition for ISBN scans.
Multipack detection
When the listing is a pack of several units, the scan flags it and works out the cost per unit, so the profit is not counted on the wrong quantity.
Live price and fees
Buy Box price, referral fee and FBA fee with size tier, plus your landed costs, for FBA and FBM.
Sales and competition
Estimated monthly sales from the sales rank, the number of offers, whether Amazon sells it and how stable the Buy Box is.
Eligibility and IP risk
Whether your account can sell the product, whether the brand needs approval, and an IP complaint risk flag with the reason.
A decision
A 0 to 100 wholesale score, BUY, REVIEW or AVOID, the recommended order quantity and the maximum buy cost.
Why matching matters more than speed
Most scanning mistakes happen before any profit is calculated. A UPC can lead to a single unit, a 3-pack and a 12-pack of the same item; an EAN typed as a number loses its leading zero; a supplier lists the price per case instead of per unit. Each of these makes a loss look like a BUY, or hides a good product. Wholesale Analyzer detects multipacks, works out the cost per unit and shows the matched listing next to every result, so you can see what it compared. The common traps are in UPC, EAN and ASIN matching mistakes.
While the scan runs, and after
- Follow the scan with live progress, cancel it at any time and re-run it with one click.
- Filter and sort the results grid, with the image and ASIN in view while you scroll.
- Get the Excel workbook by e-mail when the scan finishes: Results, a scan Dashboard and All Details. About the workbook.
- No supplier list yet? Find products and brands with wholesale product research.
- Scan the same supplier again later and compare the two catalogs to see price changes and new opportunities.
Scanner, extension or spreadsheet?
Browser extensions check one product at a time on Amazon’s page, which suits arbitrage. Spreadsheet lookups work for a short list. A wholesale scanner is for the supplier list itself: thousands of rows in one upload. To check many barcodes the manual way first, see how to check a UPC list against Amazon in bulk.
Frequently asked questions
How many products can I scan?
Up to 200,000 products per file on a paid plan. The free plan scans 50 products a month, with no card needed.
Do I need a cost column?
No. Without a cost you still get the matched listing, price, fees, sales estimates and competition. With a cost, every product also gets profit, ROI, the maximum buy cost and a BUY, REVIEW or AVOID decision.
What happens when a UPC matches a multipack?
The scan detects the multipack and works out the cost per unit from your supplier price, so profit and ROI are calculated on the right quantity.
Which file formats work?
Excel (.xlsx) and CSV files. Keep barcode columns formatted as text so leading zeros are kept.
