Service Contracts & Recurring Billing manages annuity revenue: contracts generate invoices on schedule, renewals enter a managed pipeline before expiry, prices index on renewal, and each contract shows its true profitability. For maintenance providers, IT services, security firms, and any business running annual maintenance contracts (AMCs) on spreadsheet reminders. Planned features include contract templates with billing frequency and escalation clauses, automated invoice generation with proration on mid-term changes, renewal pipeline with configurable lead-time alerts, indexation rules on renewal, linkage to FSM visits and helpdesk SLAs for delivery tracking, contract margin views combining revenue against service costs, and churn analytics. This app is currently in development on the ECOSIRE build pipeline. It will ship first for Odoo 17, 18, and 19 simultaneously, with an ERPNext port following on the v15/v16 track — the same triple-version coverage as every live ECOSIRE app. One-time license, free updates within your major version.
