Pricing and Cost Advice

"The licensing cost is dependent on the usage."

"The yearly licensing cost is very high. The solution is very expensive."

"There is no license required for the product as it is role-based. Whenever you go for a Windows platform server, the role has to be installed directly from the server manager. There is no additional cost that has to be paid for that. It is free to use."

"The solution provides multiple licensing options."
