Reports

Zen Cart has a few reports but nothing of any real value to a cart owner. You'll find you may need mods to get the type of reporting you need.

Products Viewed, Products Purchased, Customer Order Totals and Customers Referrals are the default reports.

You might these mods handy:

Sales Report

Sales Tax Reports

and of course the Apsona Shop Admin allows you to create your own reports as well.
