Most Odoo forms — whether an internal backend view or a public website/portal form — start out static. A field changes, but nothing else reacts; validation fires only after a full round-trip to the server; conditional visibility, cross-field rules and computed helper text end up scattered across @api.onchange handlers, brittle attrs/invisible domains, and one-off website controllers. When your team needs a form to behave like a real application — recompute totals as the user types, gate a submit button on a composite rule, surface an inline error before the record is ever written — Odoo core runs out of road, and a typical off-the-shelf apps.odoo.com module only patches one narrow case rather than giving you a reusable component layer.

ECOSIRE builds a made-to-order Forms Components API: a cohesive integration layer that binds your frontend and backend so a form is interactive, reactive and validated end to end. On the frontend we implement OWL components and hooks that manage field state, dependency tracking and reactive re-render, so changing one input re-evaluates dependent visibility, computed display values and enable/disable logic without a page reload. On the backend we express the authoritative rules as Python — models.Model with fields, compute methods decorated @api.depends, @api.constrains and @api.onchange — so the same validation that runs live in the browser is enforced again at write time and can never be bypassed by a crafted request. For website and portal forms, submissions are validated through JSON-RPC/controller endpoints; for backend views we extend the standard form renderer rather than fork it, so the layer survives upgrades.

The build is grounded in real Odoo mechanics, not a bolt-on widget. Each component is declared in a proper module with its own __manifest__.py, assets bundles for the OWL/JS and SCSS, QWeb/XML templates for any public markup, and access control via ir.model.access.csv plus record rules so field-level and record-level permissions are respected inside the reactive layer. Where a form needs to trigger downstream behaviour we wire it to automated actions or server actions; where it must interoperate with external systems we expose or consume the XML-RPC/JSON-RPC API. We target Odoo 17.0, 18.0 and 19.0 and account for Community vs Enterprise differences up front — the interaction and validation core runs on Community, and we flag any capability that genuinely depends on an Enterprise feature before you commit to scope.

Delivery is build-to-order and transparent. It begins with a short scoping call to map your exact forms, fields, rules and integration points; from there we produce a fixed quotation and a staged plan. Typical delivery is one working week from confirmed scope, depending on how many forms and how intricate the cross-field logic is. You receive the installable source for your version, a UAT pass on a staging database, and a documented rollback path before anything touches production. Pricing starts from $999 (indicative, single-company base scope); multi-company deployments, additional forms and integrations, deeper localization, and larger data-migration volume increase the quoted scope.
