When purchasing a license, one-time license costs per client are incurred. The license prices are graduated prices, i.e. the price per client is reduced as the number of licenses increases. This form of licensing requires a maintenance contract (support and update guarantee) with a minimum term of one year (automatically renewed) covering product support and all updates within the term.
From 1'000 clients, there is also the option of purchasing a specific site license. This additionally includes "organic growth" of workplaces. There is no need to check the number of clients in the company.
