Supply Demand Report

What is the Supply Demand Report about?

The Supply Demand Report is about identifying supply gap opportunities with proven sales. 

The report came about whilst researching products and category opportunities for large sellers and brands.  They were interested in understanding how their products and brands stacked up against the wide and varied mix of inventory available on eBay’s open marketplace.

 What was frequently discovered in the analysis was that although there could be a large amount of inventory in lower price generics, there was much less inventory in the mid to higher priced branded products.  Yet, when overlaid with actual sales data, mid to higher priced goods often had higher sales velocity.

This could be for a number of reasons:

1. Recognisable reputable brands are generally preferred by buyers.

2. High to medium priced goods that are discounted attract the opportunistic eBay buyer.

3. There is a scarcity of discounted branded products on the eBay platform.

The Supply Demand report is a really good way for finding supply gaps, testing product ideas and learning about buyer preferences for a product, category or brand.

 There can be a lot of light-bulb moments with the Supply Demand Report.  Try it out and explore the data to see where it takes you.

Overview Boxes

Overview boxes summarise the data set. The definitions of each metric are:

  • Listings: A count of the listings within the data set.

  • Avg #Sold/Week: The average number of products sold per week per listing.

  • Avg $Sold/Week: The average sales value achieved each week per listing.

  • Total #Sold/Week: The total number of items sold each week for the listings in the data set.

Data Tables

Data is presented in an easy to use tabular format with 3 distinct data view options:

  1. Seller view

  2. Brand view, and

  3. Listings view. 

Click the headers of the data table to sort. Here are the definitions for the data column as seen in the Seller view:

  • Listings: count of listings for that seller.

  • Qty: Quantity of stock available at the time that the report is run.

  • Sold: Total quantity sold by the listings included in the data set.

  • #sold/wk: Average quantity sold per week over the duration of the listing.

  • Med Price: The median price. After sorting the sold prices in order, the median price is the number in the middle of the list (or an average of the two middle numbers if the dataset is even).

  • $sold/wk: Average sales value sold per week over the duration of the listing.    

 

Charts

Charts visually summarise the data set, including any filters that have been applied. To see the Supply Demand graph, click the chart icon located at the top right of the data table.

 The Supply Demand graph uses a bar chart to show the percent of listings in each price bracket. It uses a scatter plot (dots) to show the individual listing’s average weekly sales volume.

  •  If you hover over a bar or dot, notations of metrics will appear.

  •  Clicking on a dot will open a new tab for that eBay listing.

  •  If you cannot see the whole graph on your screen, click the Hide Header button in the right frame. It looks like the 4-corners of a square.

Why are some listings included in the Supply Demand Report and not others?

The Supply Demand Report is a cohort analysis of top ranked fixed priced, multi-quantity listings that have been out on the marketplace for the last 18 months.  They have gained enough exposure to be in the top rank and have collected sales to prove buyer demand. Studying this group of listings give us a good estimation of potential sales velocity.

Excluded are auctions, single quantity listings and listings older than 18 months for the fact that they skew the data.
