Perpetual license is an ESTIM software with an initial investment in the form of a license purchase, while the second year onwards customers only pay an annual maintenance fee, or Annual Technical Service (ATS)
Subscription license is an ESTIM software with an annual subscription fee, but customers do not need to pay any maintenance fee, because it is included in the annual subscription fee. The following is a detailed explanation of ESTIM – ITSM On-premise licensing types.
