I have searched around but I don't seem to be able to get a clear answer on my questions that I understand.
Important, I have to use kendoui version 2013.2.716, internal obligation.
We do not offer the e-commerce service, we sell the e-commerce product to the customer, for him to use in his infrastructure.
My question is, do I have to buy kendoui, or can I use it without paying because the license is GPLv3?
If I use kendoui without buying, do I have to distribute the source code of the whole system or just the client code?
