There is no charge to use ESI programs. The programs are designed to be intuitive. If you find yourself in need of support (or suggestions on the application of engineering philosophy available via our "Ask Professor Coad" screen), there is a modest charge.

Our filing system is available at no charge for 90 days following your last use of ESI programs. If, after 90 days of no use, you want us to continue to store your files, there is a modest charge of $5.00 per month.

To cover any of these charges, kindly open an account with us by clicking the "Support - Suggestions - Contact" screen, following User Login below:
