Adia issues invoices weekly every Friday afternoon. By default, these are sent by email to the stored billing address.
Please note:
- The standard payment term is 7 days from the invoice date.
- If you use a separate billing address or a specific email address for invoices, please let us know. This ensures that invoices are delivered correctly and on time.
Since June 2026, Adia has been using Invevo for invoice tracking. A corresponding note can be found at the bottom of your invoice.
With each payment reminder, you will receive a secure access link valid for 7 days. This link takes you to your personal customer portal, where you can:
- View your account statement
- Download invoice copies (excluding manual receipts)
- Submit questions or complaints directly regarding reminders
- Record payment commitments
If the link has already expired or you do not have access to the portal, you can reach us at any time at support@adia.ch.
Detailed instructions on how to use the portal can be found in the attached user manual.
For special requests or individual billing arrangements, you can reach us at any time at support@adia.ch.
