I need fresh PDF and Excel templates built directly in Odoo v19. The goal is to replace the out-of-the-box exports with files that match our corporate look, so the work goes beyond switching a logo; layout, typography, spacing, and any extra fields have to feel like part of the system rather than an attachment. Here is what I expect: • You create the QWeb/XML and, where needed, Python helpers so that the new templates are selectable from the standard print/export buttons. • The design must follow the brand guidelines I will share (logo, colour palette, preferred fonts). • Every template should be responsive to different paper sizes and keep its formatting when opened in Excel or printed to PDF. • All code and assets stay upgrade-safe and sit in a small custom module that I can install on test and production databases without manual tweaks.
