As a seller on Amazon using retail arbitrage as your sourcing strategy and sales ranks, you need a reliable scanner app when scouting for products in your local stores. Listed below are the top 5 barcode scanner apps that will allow you to check prices on Amazon or eBay. 1. Amazon Seller App (Available on: Google Play, iTunes, and Amazon) The Amazon Seller app is a free app offered by Amazon that you can start using immediately as a registered seller on the platform. Once you have your seller account, simply download the app, and you can start to sell on Amazon and scanning products immediately. The Amazon Seller app and free tools will help you uncover the following such as Sales ranks and more: • Official Amazon category • FBA fees, product price • Approximate profits • Total number of sellers • Bestsellers rank • Sales Rank • …and much more. But, the Amazon Seller app doesn’t show you custom fees or taxes, which means you only get an estimate of profitability.  Also, the Amazon Seller app doesn’t integrate with eBay or Google, so it can be tough to find information on the product price history, sales history, and trends. 2. Scoutly (Available on Google Play, iTunes, and ASellerTool) This app has a great feature that allows you to switch from live search to local database mode. So if you ever find yourself in a wifi/reception black hole, you won’t have to stop your product scanning. The app contains all the information that you will find in other scanning apps, such as sales rank, including: • FBA prices • Sales Rank • Product Type • Image • Weight • Title • … and so on. Although this information on FBA and sales rank, and more are also available on all the other scanners, this app’s data/wifi-independent feature helps it stand apart from the competition. 3. Scoutify App (Available on Google Play and InventoryLab) This is a fantastic app with lots of great qualities. But it has one major downside: To use the app, you must sign up for the entire package.  You get what you pay for with Scoutify, and many excellent features will drive your success as a retail arbitrage seller on Amazon.  If you are just getting started, this app may not be the right choice because of its cost. However, if you are a seller with a high monthly volume, then this is the right app for you as it will afford you the following benefits: • Integrated third-party apps like Keepa and CamelCamelCamel • The app works in taxes so that you will get a more accurate final price number • It allows you to scan with Bluetooth • A shopping list keeps the history of your purchases • You get access to sourcing, reporting, and bookkeeping tools 4. Profit Bandit (Available on iTunes and SellerEngine) As with the option above, you need a paid subscription to use this scanning tool. However, it’s affordable and offers excellent features to help you research products in real-time. This means you can make the best-informed decisions possible as you will have the most up-to-date information at your fingertips. Because of its affordability, profit bandit is an excellent app for low-volume sellers looking to find ways to increase their profitability. 5. Scan Power (Available on Google Play, iTunes, and ScanPower) Scan power costs more than the other apps on this list. However, it also has the features to put you ahead of other retail arbitrage sellers on Amazon. It comes with the best and most accurate live data straight from the platform.  If you operate most efficiently on the go, this is the app for you. It has some fantastic features, such as sending information to your desktop while you’re out and about so you can look it over later. It also allows you to create 2-D barcodes, which is convenient so that when you ship your items, the barcodes are already there, giving you one less thing to worry about.
