Ardoise offers a free core and optional Enterprise functions. Account permissions, country, module activation and server-side pricing policy determine available actions. A visible page is not sufficient authorisation: an API may returnfeature_requires_subscription.
For an OHADA school, the founder checks Activation & Installation, modules and current conditions before paying. Finance/accounting, payroll/HR, canteen/stores, library and analytics can require separate activation. The activation code identifies an installation; it does not purchase a module. Amounts, currencies, durations and available providers come from the current preview, not fixed prices published here.
