I operate a showcave, and sell tickets to the public. My current ticket provider charges $2 per ticket sold as an up-charge to my customers. I'd like to own software that is PCI compliant (takes credit cards) and can sell tickets for cave tours. There are scheduled tours throughout the day as well as limited availability for those tours everyday. Basically, I view this as basic inventory management. I'd also like to capture customer emails for future promotion opportunities.
