Understanding “Sales” on Amazon

Amazon offers various metrics to dissect your sales data. This section clarifies these metrics, starting from the basics to ensure you capture all necessary details.

Manufacturing View vs. Sourcing View

  1. Sourcing view: Reports data that is directly related to your vendor codes
  2. Manufacturing view: Reports data for brands that you have the brand registry for (this does not include 3P sellers).

These views differ significantly:

  1. Certain metrics in the manufacturing view are independent of fulfillment, like Glance Views and Conversion Rate, including Ordered Revenue which is not tied to fulfillment.
  2. Manufacturing view might include sales from other companies selling your products to Amazon under the vendor model, though this is diminishing as Amazon prefers direct purchases from manufacturers.
  3. Sales reporting locations differ; manufacturing sales are reported in the country of the customer, while sourcing sales are reported in the purchase country.

Which view should you choose?

The manufacturing view is generally preferable unless your products are also sold by other vendors on Amazon.

Sales Metrics Breakdown: What KPIs does Amazon utilize to report sales?

Understanding Amazon's sales KPIs is crucial to avoid overestimating your budget allocation for retail and advertising promotions. Here are some key metrics:

  • Net Received
  • Shipped COGS
  • Shipped Revenue
  • Net Received
  • Shipped COGS
  • Shipped Revenue
  • Ordered Revenue

Metrics definitions

There are 7 distinct sales metrics:

Net Received (Sell-in):

The value Amazon receives on goods' arrival at warehouses.

All of the metrics listed below contribute to "sell-out". Let's explore how they differ:

Shipped COGS:

Cost attributed to the day the product ships to the customer.

Shipped Revenue:

Customer’s payment excluding taxes, tied to the shipment day.

Ordered Revenue:

Payment excluding taxes, recorded on the order day.

Key Differences in Sell-out Metrics:

Shipped vs. Ordered:

Generally, there’s a day's delay between product order and shipment, impacting reporting during promotions or for pre-orders.

The difference between the two is significant only when the specific date matters, like during promotional events. Moreover, certain industries handle pre-orders. For these businesses, distinguishing between "shipped" and "ordered" is crucial to track the volume of pre-orders. When pre-ordered items are shipped, these orders are recorded on the shipping day. Thus, in most instances, the figures will be nearly identical.

COGS vs. Revenue:

COGS is based on Amazon's purchase price, which is consistent across Net Received and Shipped COGS.

All metrics are revised to account for returns and cancellations on the day Amazon receives the return. This adjustment is crucial when comparing advertising data to retail figures.

Business Example:

Let's walk through an example, following the product through the sales process to see how each of these metrics is affected at different stages:

Amazon orders goods:
  • Amazon orders 10 books from you at a total cost of 50€. You send them to Amazon. When they arrive at the warehouse, Amazon will record 10 Net Received units and a total of 50€ Net Received (equivalent to 5€ per Net Received unit).
Amazon warehouses the goods:
  • After receiving the books, Amazon transfers them to their warehouse, where they are logged as 10 units in inventory with a value of 50€.
Customer purchases goods:
  • A customer buys one book on Sunday for 10€. On that same day, it is reported to you as "1 ordered unit at 9.35€ (10€ minus 7% tax)."
Amazon delivers the goods to the customer:
  • On Monday, Amazon dispatches the book to the customer. In your records, the Shipped Revenue will appear as "1 shipped unit at 9.35€." Similarly, Shipped COGS will be listed as "1 shipped unit at 5€."


  1. Focus on Shipped COGS for a realistic view of business performance.
  2. Avoid focusing solely on Net Received as it reflects inventory buildup rather than actual sales.

The "Cost of Goods" Pitfall

Cost of goods is based on the list price.

The cost of goods is calculated from the list price. Often, manufacturers offer Amazon discounts between 10-30%. This discrepancy creates a "trap" where the COGS is 10%-30% more than what Amazon actually pays you. However, there's a straightforward method to calculate this discount applied to COGS: Shipped COGS minus (Shipped Revenue multiplied by Net PPM).

Sell-in vs. Sell-out

It's essential to monitor Net Received, Inventory, and Shipped COGS closely to gauge the health of your business.

By analyzing these metrics, you can determine whether Amazon is accumulating stock. If inventory levels are rising, it may indicate that your business isn't performing as well as it appears, and Amazon could decrease future orders to clear out excess stock.

On the other hand, Amazon might be reducing its stock levels because it is selling more units to customers than it is purchasing. This reduction could indicate that Amazon had previously overstocked, or that they might be planning to place larger orders in the near future.

This trend is especially important to monitor in Q4, when Amazon typically accumulates large inventories and then scales back orders significantly in Q1. Failing to keep track of these trends could lead to an overestimation of Q4 performance and an underestimation of Q1, potentially resulting in poor investment decisions.

Which retail metric should you use to compare with advertising sales?

Amazon's metrics for Sponsored Ads and DSP are quite similar to Manufacturing Ordered Revenue. They report the customer price excluding taxes but do not adjust for returns. This means if your products have a high return rate, you should adjust your advertising performance downwards to avoid overstating the media contribution and media ACOS.

Additionally, there are two other key differences to be aware of:

  1. Some types of advertising campaigns record data based on the day the ad was clicked, rather than the day an order was placed or shipped.
  2. Depending on the campaign type, Amazon might report revenue based on the product advertised, not the product actually sold. This phenomenon, known as the brand halo effect, can create discrepancies in media contribution reports, particularly when analyzing short time frames or individual products.
