LISA Business extends Business Central beyond basic recurring billing into full Revenue Model Management: recurring subscriptions, consumption and usage-based billing, one-time fees, add-ons, and resold agreements, in one lifecycle. Bill fixed quantities or actual metered usage, with minimum-consumption thresholds protecting baseline revenue. Run calendar-aligned or anniversary-based (rolling) cycles, with automatic first-period pro-ration handled for you. Generate recurring physical or digital deliveries on their own cadence with delivery schedules. Create or import contracts from quotes, orders, feeds, and workflows; manage renewals, amendments, and cancellations with full version control and audit trail; and let batch operations orchestrate it all with minimal intervention.
