REVVO back-office sequence diagram orchestrates role-based workflows across authentication, administration, operations, finance, and reporting modules. Administrator, Manager, and Comptable actors authenticate once, then branch into dedicated operational flows: Administrators manage users, rights, and system settings; Managers oversee Catalogue, Stock, Achats, Ventes, Depots-vente, and SAV/RMA with automatic stock synchronization; Comptables handle Facturation and Paiements with invoice reconciliation. All roles converge on Statistiques for unified reporting and insights. This architecture demonstrates separation of concerns, role-based access control, and event-driven stock updates across interconnected business domains. Fork this diagram on Diagrams.so to customize workflows, add new roles, or integrate additional modules like CRM or supply chain planning. The sequence pattern ensures data consistency through explicit include-relationships for stock movements and invoice generation.
