All of our commercial software comes with a dual guarantee. Firstly it can be freely downloaded in evaluation form to enable you to test it on your own computer and to apply it to your own problems. This gives you a no-risk, no-obligation trial. The second guarantee is that if after this trial period you do decide to purchase the software, and then find within 30 days that it is unsuitable, we will refund the full purchase price. All that we ask is that you tell us what it was that only became apparent as a problem after the purchase, so that we can fix it in future releases.

Each software package has a full description of the ordering procedures in the online Help and in the manual. Procedures are included for ordering via the internet, by telephone, by fax, by email and by snail mail. Payment can be made by Credit Card or by Purchase Order.
