How it Works

Limit Buster - See Real Stock Numbers

Under the product research section, you will be able to “bust” a seller’s limit by clicking the limit buster button. This will reveal the true inventory of that ASIN per seller. Clicking the total button will automatically add all the busted inventory for all sellers and give you the current total inventory.

ASIN Monitoring - Keep Track of Products

Under the monitoring section you can add products (ASINs) to the product monitor. The software will then automatically bust each sellers limit every 24 hours and total them up for you. Checking a seller's inventory is now automated along with all the other data points such as reviews, BSR, price, Q&A, etc. Set it and forget it!

Alerts & Trends - Stay Updated

You can set alerts to be sent via e-mail everyday to see what's changed day to day to gather trends and make adjustments accordingly. Howmanyextension utilizes machine learning to predict trends and future changes based on historical data. Once a product has been monitored for long enough the system will be able to display predictive insights.
