A perpetual license is one where you pay a one off fee and then you own it - forever.

Examples of a perpetual license scheme is Open Licensing, Full Packaged Product and Original Equipment Manufacturer (OEM)

Reasons why to choose a perpetual programme:

• one off fee, no need to budget further
• you own the license for life
• You can buy as little as a single license
• buying decisions may be easier for smaller amounts
• software assurance can be combined to allow for product upgrades
• open license software can be installed using a single code
• no storage of media needed for open licenses (downloadable)

Reasons why not to choose a perpetual programme:

• normally costs more as an initial outlay
• future costs for upgrades less predictable
• managing multiple license purchases can be difficult
