tool4seller Barcode Scanner

by Tapcash Inc.

Overview

tool4seller Barcode Scanner helps Amazon retail arbitrage sellers research products by UPC, EAN, GTIN, ISBN or ASIN. Select a marketplace, compare product matches, review available prices, seller count, sales rank and history, then estimate FBA or FBM fees, profit, margin and ROI using your costs. It uses your existing Barcode account and can read your connected Amazon store list when you choose. Product searches and research save minimal activity or observations in Barcode; profit estimates are not saved. It does not create listings or ads, and estimates do not guarantee profit or selling eligibility. Developed by Tapcash Inc.; independent of Amazon.

ChatGPT

Estimates FBA or FBM fees, profit, margin, and ROI from a selected marketplace, ASIN, expected sale price, purchase cost, and fulfillment method.
