What exactly means: "… for upto 200 customers"?

Hello.

I wish to know what exactly means: “Gratisfaction is absolutely free for upto 200 customers”. In the free trial version I can see a limit of 200 customers data, but if I have more than 200 customers the system continues working, but I can’t view the data of all users, only 200, and the system will work only with those 200. Is it right or am I wrong?

Thanks in advance.
