Download PerNetFlow

After you've read the free book!

PerNetFlow is a Windows program that you download and install on a desktop or laptop computer. The program can also be installed on Apple devices with the addition of a Windows emulator program such as Parallels (parallels.com).

At its core, PerNetFlow is an automatic spreadsheet application. It’s too big to fit on a mobile phone. And you won’t be using the program often enough that you will need to carry it with you at all times.

Your 60-day free trial starts the first time you start the program.
