Questions
Before you download.
Something else? Write to support and the developer answers.
Do I need an Amazon seller account?
No. You can scan products and see profit, fees and sales before you open a seller account. You only need one when you're ready to sell.
Which Amazon marketplaces does it cover?
United States, United Kingdom, Spain, Italy, Germany, France, Canada, Mexico, Brazil and Japan, each with its own fees and currency.
Where do the fees and sales numbers come from?
Fees come from Amazon for each product. Price, rank and offer history come from Keepa. Sales a month are Amazon's own "bought in past month" figure where available.
Does it work for online arbitrage?
Yes. Search by product name or ASIN instead of scanning, and use the same profit calculator.
How does the free trial work?
You get every feature for 7 days. Cancel in your App Store or Google Play settings before day 7 and you pay nothing.

No. Profit Mate is an independent app by JM Software Studio and is not affiliated with Amazon.
