Most teams running Odoo end up managing real contracts in a patchwork: PDFs on a shared drive, renewal dates in a spreadsheet, approvals over email, and no single record that ties an agreement to the invoices it generates. Odoo core gives you sale.subscription (Enterprise) for recurring revenue and the documents/sign apps for storage and signing, but none of that models a contract as a first-class object with versions, a negotiated clause set, milestone obligations, expiry windows, and an audit trail. When a renewal slips or an SLA breach goes unnoticed, the cost is revenue leakage and disputes — not a missing feature you can toggle on.

ECOSIRE builds a dedicated Contract Lifecycle module that adds a proper contract.agreement model (with contract.version, contract.clause, and contract.milestone companions) on top of your existing Odoo. Contracts are assembled from reusable templates and a versioned clause library, moved through a configurable state machine (draft → review → approved → signed → active → expired/renewed) with approval steps enforced by record rules, and signed through Odoo's native sign request flow or an integrated e-sign provider over the JSON-RPC/XML-RPC API. Every edit creates an immutable version snapshot so you always know what was agreed and when. @api.depends computed fields derive next-renewal and next-milestone dates; ir.cron automated actions raise activity reminders and email alerts (via QWeb templates) ahead of expiry, notice periods, and milestone due dates.

On the money side, an active contract links to Odoo's recurring-invoicing engine so agreed lines, billing frequency, and price escalations generate account.move drafts on schedule — with SLA terms (response/resolution targets, penalties) recorded on the contract and surfaced to Helpdesk or Project where relevant. Access is governed by ir.model.access.csv plus record rules so sales, legal, and finance each see the right slice, and a customer/vendor portal controller (extending /my) lets counterparties view their own contracts, download the signed PDF (rendered via a QWeb report), and see upcoming renewals — without a backend login. Everything is delivered as a clean, upgrade-safe module: no core patches, standard ORM and view inheritance only.

Because this is build-to-order, we start from your actual contract types and approval reality rather than a generic template. After a short scoping call we confirm the models, states, clause taxonomy, alert cadence, and billing rules, then build against your Odoo version (17.0, 18.0, or 19.0) and Community or Enterprise edition. Typical delivery is one working week from confirmed scope. You get the installable source, a staging UAT pass with a rollback plan, documentation, a training session, and a post-go-live support window — plus the git repository so the module is yours to keep and extend.
