Table of prices
A big update of Lesosai is done at the beginning of each year. The current version is Lesosai 2019 (see news). Lesosai updates are billed only once a year, all secondary updates are included in the annual update price. The amount of the update is reduced by 10% for customers who have subscribed to the service after sales by e-mail (200 CHF HT per year and per license).
Updates are not mandatory, but we can only insure the news for customers choosing to upgrade to the Lesosai 2019 version, sold from its release in January / February until 31 December 2019 at least. Changes during the year remain free, improvements are available immediately. It is not interesting to wait: the payment of the update is only valid until the release of the next version, each year.
