This video shows the Amazon Seller stats page on ManageByStats.com. The page shows all sales broken down in many different ways, including by Brand, Product Line, SKU, etc.

This is what we call the Amazon seller
stats page.
It shows your bi-weekly sales statistics
broken down in several different ways.
When you first land on the page you will
see your statistics presented by SKU,
for the last two week period. And the
statistics on this page are always shown
in two-week periods to match Amazon. If
you’re in the middle of a period
it will of course not show a full two-week period at that point.
You can click on the prior button and
move back
one two-week period at a time. Under the prior
and next buttons you will see 5
additional selections for
brand, product line, product name
ASIN and SKU. This will show you the
statistics broken down by
that specific selection instead if
you click on any of those.
For example, clicking on brand will show
you your total numbers for the period by
brand. Clicking on the product line button will break it down by the product line
and so forth. At the bottom of the page
you will see some
additional debits or credits from Amazon
that are not linked to specific products
but are items like warehouse storage
charges
bulk shipping charges to Amazon’s
warehouse,
monthly account charges, etc. And at the
very bottom
you will see the net number after
credits and debits
