What can you do in the Buy Box & Inventory module?

  • Seller Monitoring: overview of other sellers selling your product 
  • Buy Box and Price: overview of the Buy Box win rate at the product level and product pricing history
  • Price Monitoring: get a complete view of your pricing history and benchmark against your Minimum Advertised Price

  • See where your product selection overlaps with the selection from third party sellers
  • Find out who you are losing the Buy Box to and why
  • Selection Share compares a seller's selection of ASINs to what you have uploaded online. If your products are not in stock or have been deleted, the selection share will not be 100%
  • What is the Buy Box Share? The share of Buy Box that a seller has for a specific product, within the chosen time frame. If your products are not in stock or the Buy Box status has changed over the selected period of time (for the uploaded products) the Buy Box share will be lower than 100%. Please note that the percentage might be higher than 100% if a reseller is selling 2 pieces of a certain product on the same day and owned the Buy Box the whole time.
  • Average Sellers: Average numbers of sellers per product. In the picture above you can see your products have another 32 suppliers on average. 
  • Unique Sellers: Total number of sellers that sell at least one of your products. The client is selling 24 products and another 135 sellers are selling one or more of his 24 products.
  • What is the average Seller Rank: The Seller Rank gives you an indication of how many other sellers are selling the same product and how you rank against them. Please note that it is not the same as the Best Seller Rank. In fact, this is your rank based on a specific product and at the Buy Box level. 
  • If you want to see your products, you need to click on ‘Amazon’ and then you will see all the products and their average seller rank, Buy Box share & average price difference.
  • Export of the data is available


  • See the status of the Buy Box on the product level
  • Find out why you are not winning the Buy Box: Is it because the product is out of stock? Is it because one of your sellers is selling your products for cheaper? Who currently has the Buy Box? 
  • Review by product level- how many other sellers are selling this product? What is the Amazon seller rank? What is the average price?
  • Export of the data is available
  • Buy Box History on the Product level: See the trend on the product level for your selected period
  • Price monitoring: see how your prices change over time. The price Monitoring Feature allows you to upload your Minimum Advertised Price for all your products in bulk. It will track any changes that happen to your MAP. You can set up the MAP Alert to be notified when a seller is driving down your price.


Key Highlights:

  • Pricing history — See how your prices change over time
  • Customize and analyze your Minimum Advertised Price (also via bulk upload)
  • MAP-Alert: Receive a notification when your Minimum Advertised Price is undercut

Understand the history of your pricing

How low did your price drop? When did it happen? If you lost the Buy Box — who offered it cheaper? Find out who undercut your prices and identify historically vulnerable products.

The Price Monitoring Feature lets you see Amazon’s price as well as the lowest seller price (with or without shipping costs).

Full control over your Minimum Advertised Price

Your MAP sets the tone for your brand and keeps the balance with other (re-)sellers — after all, you don’t want them to complain about other sellers receiving better purchasing conditions.

To stop seller complaints and potential damage to your brand, you need to know: Was my MAP undercut? By how much, and for how long? Or conversely: Is the lowest price actually above my MAP?

The Price Monitoring Feature allows you to upload your Minimum Advertised Price for all your products in bulk. It will track any changes that happen to your MAP. Use the column view to change individual prices. 

No more surprises: Take immediate action with the MAP Alert

Get in touch with your vendor manager the moment your MAP is undercut. The MAP-Alert notifies you within the tool and via email as soon as a seller drives down your price. The vendor manager can make sure that Amazon will continue to your order your product — despite temporarily low margins. 

Great for agencies: Save time and satisfy your clients by producing automatic reports about who lowered which prices over time.


  • Check the current ‘Amazon 1P In Stock’ status 
  • How many days is the product Out of Stock
  • What is the stock history for the selected time frame


  • 90% of the sales go to Buy Box Owner. Check which of your sellers are selling your products on Amazon. Monitor your competition.
  • What is the average 1P and 3P price for your products? Is one of your sellers under-cutting the price of your products? Sellers use a commission model to sell their products and thereby control their price. Others brands use hybrid model of a seller and a vendor account to try and influence the price in-house. Having an additional seller account helps you push sales, influence the price of your product, and retain sales when you go Out of Stock on your vendor account.
  • Short-term: you can run a promotion to change the price of your product for a short amount of time. Make sure that the lower margin will be justified with the additional sales.
  • If you have lost the Buy Box, your Amazon Advertising campaigns on those products will be paused. Check your campaigns to ensure you have backup ASINs winning the Buy Box to prevent any interruptions to your advertising.
  • Set up alerts for when you lose the Buy Box and go out of stock
  • Use the Retail Analytics module to monitor how often Amazon selects your inventory, and how often they source products from other wholesalers to fulfill the Buy Box sale (see below). You can also use this module to monitor your Sell-In and Sell-Out data, to help you to better plan your inventory and improve your forecasting models.
