Use the form below for general enquiries, information requests and proposal requests alike — select the request type that matches your need and we will route it to the right team. Messages may be written in English, Portuguese or French. We aim to respond within two business days, in the language of your message.
To help us respond precisely, it is useful to tell us where your organisation is headquartered, how it currently interacts with Portuguese public entities — meetings, correspondence, position papers, consultation responses — and whether it acts in its own name or on behalf of clients. If your question concerns the act of registration itself, we work in articulation with rtri.pt, the ecosystem's registration-focused website; for training in Portuguese, we will refer you to representacaodeinteresses.pt. Confidential matters can also be raised directly by email or telephone with either office before any documentation is shared.
The form is processed by our team in accordance with the Audiqcer privacy policy.
