Recurring & Subscription Billing

ECOSIRE builds a Recurring & Subscription Billing module tailored to your contracts and billing policy. At its core is a subscription model (models.Model) that carries the plan, billing cycle (monthly, quarterly, annual, or a custom interval), next-invoice date, and lifecycle state managed through a proper state machine (draft → active → paused → cancelled → expired). Recurring invoice generation runs off an ir.cron scheduled action (an automated action) that scans subscriptions whose next_invoice_date has arrived, drafts account.move records against the correct journals and analytic accounts, and advances the cycle — all idempotently, so a re-run never double-bills. Amounts on mid-cycle plan changes are handled by compute methods decorated with @api.depends, applying day-count proration so an upgrade on the 12th charges only the remaining period.

On top of the recurring core we build the pieces native Odoo makes you improvise: configurable renewal handling (auto-renew, renew-with-notice, or manual approval), cancellation with end-of-term versus immediate-with-credit-note options, and an optional usage/metered billing lane where consumption records aggregate into each period's invoice line. Access is locked down with ir.model.access.csv plus record rules so account managers see only their own customers' subscriptions, and every plan, invoice, and renewal is driven from clean backend views (XML) with QWeb subscription and renewal-notice reports. Because everything is standard Odoo accounting underneath, your existing tax, multi-currency, and payment-provider setup applies, and the whole engine is reachable over the XML-RPC / JSON-RPC external API for integration with a storefront or CRM.

This is a build-to-order engagement, not an instant download. We start with a short scoping call to map your billing cycles, proration policy, renewal rules, and edge cases, then build the module against your Odoo 17.0, 18.0, or 19.0 (Community or Enterprise) environment. Typical delivery is 2 to 4 weeks from confirmed scope. You receive the installable source, deployment on a staging instance for UAT, and a defined post-go-live support window — no fabricated benchmarks, just a module built to bill your customers correctly.
