Image from store Amazon FBA Calculator,Competitor Stocks,Sales
Description from store There are three critical steps before you decide to sell/restock a product on Amazon. Sellcaster is the only tool in the market which helps you do all these ✪ Estimate the overall demand for the product ✪ Ensure you know the FBA fees involved and calculate profitability ✪ Monitor the inventory levels of your competition and stock accordingly (daily limit of 8 applies) Sellcaster works on all 11 Amazon websites : US, UK, Canada, Germany, France, Spain, Italy, Spain, Mexico, India, Japan & China. We do not need access to your credentials to sellercentral. How is Sellcaster different from other FBA calculators and Sales estimators? ✪ Fees, products, demand change constantly. Stale data can lead to significant loss, Sellcaster gives you real time data needed for decision-making. ✪ Pricing, sales rank, inventory levels and other Amazon data are extremely dynamic. Other tools work on point in time data whereas Sellcaster uses moving averages (for estimates) which results in an accurate forecast. ✪ Sellcaster learning algorithms provide accurate demand estimates as they learn from actual sales, inventory level, sales rank changes instead of pegging the estimate simply based on current sales rank. ✪ For sellers on Amazon European marketplaces, this is the only FBA calculator which includes VAT in profit calculation. Even Amazon’s official FBA calculator does not include VAT and overstates profit. ✪ Sellcaster shows all the info on a small window which you can use interactively, unlike other tools which bury info deep inside the page.

  • (2018-08-07) Axako Axako: they wont let you CANCEL!! THERE IS NO WAY EXCEPT TO CALL CREDIT CARD. They will tell you to visit website but nothing there to cancel. They will then tell you to see Google payments but no way there either. DO NOT INSTALL THIS! They are not correct. They will get your money and give you no way out except by calling your credit card. Please review them if you have the same problem.
  • (2018-04-25) JZ: not accurated
  • (2018-03-22) Daniel Fuchs: Never fixed the issue
  • (2018-02-11) Jeremy: After an Amazon update around mid December we stopped getting accurate competitor stock. I decided to keep my subscription expecting a fix but it never came. After paying Jan/Feb in good faith to support the developers they still have not fixed the issue. I contacted sellcaster over a week ago for a refund or credit and haven't heard a word from them -Before this issue, sellcatser was a 5star app. That is no longer the case due to lack of updates and slow/nonexistent customer service
  • (2018-01-28) Mpampis Mantoukas: Δουλεύει όποτε του αρέσει. Χρήσιμο δωρεάν εργαλείο μεν αλλά τουλάχιστον ας δουλεύει όλες τις φορές. Nice tool but works every it wants! Not always! Very disturbing.
  • (2018-01-18) Blitz: It was good now doesn't even work half the time. Signed up to pro. I paid for it and it's not upgraded me to pro. Wasted money.
  • (2018-01-14) Alex Arvat: The stock figures are not real at all, that is on all type of sellers not just Amazon. I have just payed for the basic subscription specifically for monitoring competitor stocks... Will the app be updated to show real values? Thank you in advance for the answer.
  • (2018-01-12) Levi D: Not accurate at all. Tested with my own listings
  • (2017-12-19) Dustin Phillips: Just downloaded this and it tells me to open in Amazon, or refresh the page. I was on Amazon and it still did not work. Deleted the app.
  • (2017-12-15) Kent Kan: good!
  • (2017-12-13) Bea Heitner: We used other extension before trying this as quantity tracking is important. Amazon made changes and now this extension does not work for quantity. The only one we found now that is working perfect is from Amzpecty. Quantity and tracking is perfect. This interface on Sellcaster is very nicely done why I give it two stars, but the data is wrong. Hope it can be fixed and will try again.
  • (2017-12-03) Michael Eduardo Conde: Shows you the Estimated Sales, Competitor Inventory. The Profit and Fee Calculator is Amazing, you can try out figures that you want aside from its default. You can change its setting, how it pops up. I give it more than five stars if it shows the reviews of specific-size/color, color reviews, sizes reviews. I think soon it will be a paid extension.
  • (2017-11-22) Sheng Y: Doesn't work properly. Most asin I tried was loading all the time.
