Finance and operations teams running Odoo across more than one company hit the same wall the moment they need branded output: quotations, invoices, delivery slips, and purchase orders all render through the same shared QWeb templates, so every legal entity prints on the same generic page. Odoo's external and internal report_layout settings give you a header logo, a company color, and a font, but they do not provide a true full-bleed background image behind the document body, nor a diagonal DRAFT / COPY / PAID watermark, nor — critically — a way to make those assets differ per company. The usual workarounds are pre-printed stationery (which breaks the moment someone emails a PDF) or hard-coding an <img> into a template override that then applies to every company on the database and quietly regresses on the next upgrade.

This is a productized module that ECOSIRE builds to order for your database. We add a per-company configuration layer on res.company (background image, optional watermark image or text, opacity, tiling versus full-page stretch, page-margin behavior, and per-report-type toggles), stored as fields.Binary / fields.Char / fields.Float and exposed through a clean Settings view driven by res.config.settings. At render time the resolved asset is injected into the QWeb pipeline through a small template-inheritance layer over web.external_layout (and web.internal_layout where needed), using an <t t-set> lookup on the document's own company rather than the logged-in user's company — so a multi-company invoice batch prints each record on the correct entity's stationery. Because Odoo renders PDFs with wkhtmltopdf, we implement the background as a fixed, print-safe CSS layer (position: fixed with controlled z-index and @media print rules) so it sits behind the content on every page without pushing the body or clipping the header/footer bands.

Technically, the module ships as a standard addon with its own __manifest__.py declaring dependencies on web and the relevant report modules, an inheriting view set, and ir.model.access.csv plus record rules so only users in the right group can change a company's background and watermark. It respects multi-company record rules end to end, so a user restricted to one company never sees or edits another entity's assets. We keep the QWeb override thin and additive so your existing custom report templates keep working, and we can scope the watermark to fire conditionally (for example, only while an invoice is in draft, or a COPY mark on reprints) using t-if on the record state. It targets Odoo 17.0, 18.0, and 19.0 and works on Community and Enterprise; where Enterprise-only report layouts are in play we adapt the inheritance point accordingly.

Delivery is build-to-order. After a short scoping call we confirm which report types, which companies, and which watermark rules you need, then build against a copy of your environment, run UAT on a staging database, and install on production with a rollback path. Typical delivery is 2–4 weeks from confirmed scope. Pricing starts from $249 (indicative, single-company base scope); the number of legal entities, additional report types, conditional/state-driven watermark logic, and integration with heavily customized existing report templates increase the quoted scope. You receive a fixed quote after the scoping call, never a surprise on the invoice.
