The Software Maintenance is automatically included for the first 12 months after the software is purchased. Afterwards, a renewal of the Software Maintenance is available at an annual maintenance fee of 20% of the total software licence value.
If you choose a Monthly Rental licence, Software Maintenance is always included.
