Sales team

I would like to purchase this system but how can i talk to sales team?

There is no sales team. Determine the version you want and click its link on the menu bar. Download the desktop edition for free, forever. Download the server edition as a trial for free. Buy it from within the program if you like it. Subscribe to the cloud edition or start a free trial on its web page.

If you have questions before making a decision, ask them on the forum or read the Guides.
