Is the pro-version purchase one-time or annual?
the Handsontable PRO license is a one-time purchase (perpetual License). However you lose an ability to update to newer versions after 12 months of the purchase if you do not buy a renewal for the Support and Maintenance plan.
Our team has many developers. But only two developer need use handsonetable. Can we buy licence only for two developers?
Yes, you only buy the license for developers who are working with the Handsontable Pro source code.
If you have any additional questions feel free to ask.
