The ability to be able to keep up with our clients' needs while remaining flexible in terms of pricing structures was great! We had challenges with some modules not displaying properly or having bugs that prevented us from effectively using them. For example we were unable to use one module where you could see all your customers but it would freeze every time someone navigated between pages. I'm sure this has been fixed now though. It really makes sense financially as well since it's so easy to add more features than what most people need without breaking the bank. Our previous version couldn't handle multiple tour operators which meant there wasn't enough flexibility when adding new products/features. This allowed us to have an easier process of keeping track of everything going into production.
