Whenever possible take full advantage of evaluation or demo version of the software. Be sure that differences between evaluation and full version are minimal to avoid unpleasant surprises after the purchase. Evaluate as many features as you can, and try to apply them to specifics of your business. Try to get a feel as to what it would be like to use the software on a daily basis.
Many vendors will require a credit card to be placed on file before you will receive access to evaluation version of the software. TimeCurve Software does not require a credit card information in order to evaluate TimeCurve Scheduler.
