Nous développons une application mobile de facturation destinée aux artisans du bâtiment. Celle-ci a pour but d'aider ces personnes à générer des devis, factures, attestations pour la TVA réduite et rapports d'intervention de manière intuitive et simplifiée. L'idée est de proposer à nos clients un plan mensuel, facturé au mois le mois, et un plan annuel, facturé une fois par an.
