Forecasting Customer Demand: A Key Factor in Inventory Optimization

The report scrutinizes various aspects, including customer demand and additional variables, to estimate the projected customer demand on a weekly basis in the immediate upcoming period.

These findings are valuable for formulating inventory strategies and anticipating forthcoming Purchase Orders, with the aim of minimizing product unavailability periods on the website.

It is important to note that this analysis provides a forecast and does not assure precise future demand. Additionally, it should be emphasized that it does not serve as a Purchase Order forecast but represents just one of the variables utilized to generate Purchase Orders.

How do you access the Forecasting Dashboard on Vendor Central?

  1. Log in to your Vendor Central account using your credentials.
  2. Once logged in, navigate to the “Reports” tab or a similar section.
  3. Click “Retail Analytics”
  4. Click “Forecasting”

The dashboard provides a number of different metrics, including:


P-levels: Modify the desired P-levels you wish to examine using this feature. P-levels indicate the probability of meeting customer demand at different stock levels. For instance, if a P70 forecast indicates 400 units, it means there is a 70% chance that actual customer demand will be 400 units or lower. This also implies a 30% probability that customer demand will exceed 400 units. Lower P-values signify a more conservative estimate, while higher P-values indicate an optimistic assessment of customer demand.

Mean: The best estimate for customer demand, known as the mean forecast, is provided by Amazon.


By selecting this option, you can filter the results for a specific ASIN (Amazon Standard Identification Number) or multiple ASINs (up to 100).


To sort the results, click the arrow icon in any column. For instance, sorting the results by the Product Title column will arrange them alphabetically based on the product title. Clicking the arrow again will reverse the sort order.


These columns display the projected customer demand for each product for up to 25 weeks in the future.


Let’s explore a practical example to demonstrate the type of information you can gather using this dashboard.

Suppose we have scheduled a promotional campaign that will commence in 7 weeks. Using the forecasting report, we can evaluate the estimated customer demand and adequately prepare our stock.

Follow these steps:

  1. Click the “Show additional filters” button to expand the menu.
  2. Enter the ASINs corresponding to the desired products. You have the flexibility to enter multiple ASINs, with a limit of up to 100 entries.
  3. Click the “Refine Results” button.

You now have the opportunity to analyze the anticipated customer demand for the forthcoming weeks. During week 7, which aligns with the promotional period, Amazon’s advanced systems evaluated the potential impact of the promotion using a comprehensive range of data points, including historical records, brand recognition, promotional parameters, and various other factors. The projected average for that specific week is 25,390 units, significantly surpassing the average for other weeks.

This valuable information can be employed to manage your inventory effectively and, in conjunction with additional insights (such as the current available inventory in Amazon Fulfillment Centers, accessible through the Inventory Dashboard), proactively estimate the quantity required for future purchase orders.
