Support, Upgrade & Maintenance (SUM) Agreement
AFT is becoming one of the few software companies that sell perpetual licenses. Once you purchase your AFT license, you own the license and any models and data created for as long as you choose to use it. We do not force customers to purchase a new license on an annual basis to continue to access software they already own. AFT does encourage customers to take advantage of SUM agreements to receive premier support as well as new versions of the software.
