Amazon is the leading eCommerce marketplace in the world. Thousands of sellers participate there trying to reach their target audiences and make revenue from selling things. But the industry is very competitive, and an eCommerce start-up cannot succeed without a well-thought-out strategy.

Successful selling requires the ability to monitor and analyze a lot of data. Without this dedication and effort, even the best digital solutions won’t boost your Amazon sales in the PrestaShop store. 

In online selling, there are a lot of important metrics to monitor. In this review, we will focus on key aspects you can track. And we will take about our PrestaShop Amazon Integration that provides you a number of useful amazon tools for sellers. Let’s examine 5 key metrics for an Amazon seller.

Order Defect Rate

What is Order Defect Rate on Amazon? In a nutshell, this is a metric that indicates the quality of customer service. It represents in percentage how many customers aren’t satisfied with the quality of products or with the quality of service provided.

The Order Defect Rate is determined by the following things:

  • Negative review provided by the customer;
  • The A-to-Z claim;
  • The Chargeback claim.

Since the competition on Amazon is pretty tough, the marketplace doesn’t tolerate Order Defect Rates higher than 1%. If you don’t manage to keep it lower, the platform can even charge a suspension for your PrestaShop store. That’s why you should pay a lot of attention to these metrics and a lot of effort to change the percentage for the better.

Inventory Performance Index

Amazon added one more interesting metric called the Inventory Performance Index. This metric measures the ability of a seller to manage the assortment and inventory of the online store. 

The highest score one can receive here is 1,000. It’s not obligatory to achieve it to be well-ranked. A score above 400 is a good indicator of your inventory performance. You should try to keep it not lower than 350 points since such an index means that you need to take serious actions to make it go higher.

If you manage to keep track of this metric, you will be able to prevent potential decreases in your sales.

Perfect Order Percentage

The Perfect Order Percentage is a metric opposite to the Order Defect Rate. If your store has a high Perfect Order Percentage, this means that all the processes that were involved in selling were executed perfectly. This metric takes into account the whole process – from placing the products in your stock to delivering them to the clients.

Keeping track of this metric allows for measuring the efficiency of your store. If you see that one aspect causes it to go down, you can faster determine what actions should be taken to eliminate the issue.


One of the ways to increase earnings without boosting sales is to decrease expenses. When selling things on Amazon, one of the expenses you have to pay are fees. Tracking fees might help to minimize them. Of course, you can’t impact them, but you can see for which products the biggest fees are charged and regulate your assortment properly.

Smaller fees are charged for smaller products. Take a look at your stock. If there are too many big-size goods, maybe, it’s a good option to substitute them with a bigger quantity of smaller ones. 

One more helpful thing is to fulfill goods yourself. This might be too difficult if you have a large assortment. But if your online store is just a beginning Amazon startup, this might be very helpful at the beginning stage.
