Every stock Odoo deployment stamps a promotional attribution into the public website footer, the bottom of outbound email templates, and the customer portal pages. For an agency reselling an Odoo-based platform, a business emailing branded quotes and invoices, or anyone presenting a polished storefront, that leftover attribution quietly undercuts your brand at exactly the customer-facing touchpoints that matter most. The catch is that Odoo core exposes no single supported toggle to strip all three surfaces at once: the website footer text lives in a QWeb website view, the mail sign-off is baked into the notification layout used by mail.thread, and the portal footer is rendered by yet another set of portal views. Editing them by hand through the UI is fragile — a module update or a -u website upgrade re-applies the standard views and the branding quietly reappears.

We build a small, self-contained module scoped to your exact edition and version that removes the attribution cleanly and durably across all three surfaces. It ships as a proper addon with its own __manifest__.py declaring dependencies on website, portal, and mail, and it overrides the relevant QWeb templates using <xpath> inheritance rather than deleting or corrupting core records — so upgrades stay safe and the change survives future -u runs. The website and portal footer attributions are neutralized through inheriting views (website.layout, portal.frontend_layout and their footer blocks), and the outbound-email sign-off is handled by inheriting the mail.notification.layout and mail.mail_notification_light templates so that every transactional email — quotations, invoices, portal invites, delivery notices — leaves your system without the default footer line.

Because the change lives in one addon rather than in scattered UI tweaks, it is auditable, version-controlled, and reversible: uninstall the module and Odoo reverts to standard behavior with no residual data. Where your deployment adds extra branded surfaces — a custom email theme, a website theme with its own footer snippet, a multi-website setup, or Enterprise-only mail layouts — we extend the same inheritance approach to cover them. We validate against Community and Enterprise, and against your specific Odoo 17.0, 18.0, or 19.0 build, since the exact template xml_ids and footer markup shift slightly between versions and editions.

Delivery is build-to-order. After a short scoping call we confirm the exact surfaces in scope, your edition/version, and any custom themes, then build and test the module on a staging copy of your database before installing on production. Typical delivery is 2–4 weeks from confirmed scope, depending on how many custom branded surfaces and themes are involved. Pricing starts from $249 (indicative, single-company base scope); additional websites in a multi-website setup, custom email themes or theme-specific footer snippets, and deeper localization of email layouts increase the quoted scope. You receive a fixed written quote after the scoping call — never a surprise.
