Calculateur de matérialité
La matérialité constitue la pierre angulaire de chaque mission d'audit. L'ISA 320 exige que les réviseurs d'entreprises déterminent la matérialité pour les états financiers pris dans leur ensemble lors de l'établissement de la stratégie d'audit globale. Le référentiel choisi et le pourcentage appliqué dépendent de la nature de l'entité, des besoins des utilisateurs des états financiers et du jugement professionnel de l'auditeur.
