The software, like many others, doesn't have a fixed price. It's price is based on your needs and probably on the modules offered by the developers. The price can be obtained after you contact the developers or the Sales team. Unfortunately, there is no email for Sales team, but you can use the Contact options available on the official website to get in touch with the developers. They should provide the price, updates, upgrades, modules, and payment methods. This usually happens for applications that are very expensive or exclusive to certain areas of work.
