[Get a free demo](https://info.onedoc.ch) ## Everything you need to know about sending invoices to the TG for patients ###### Send your invoices via a secure link Your patients receive an email containing a secure link to download their invoice and any reminders. For added privacy, __each invoice is protected by two-factor authentication__: patients log in using an SMS code and retrieve their TG invoice from the secure OneDoc patient portal. This ensures no sensitive data is exposed in email attachments, avoiding the risk of leaks via insecure and non-sovereign email services like Hotmail or Gmail.   ###### Add a cover letter to the invoice Enhance your patients’ experience by automatically attaching a cover letter to your invoices. __You can create a template tailored to your needs__ and include all key information. The letter is automatically provided in the patient’s language for clear and professional communication. ###### Protect patient data with temporary links Each link to an invoice is valid for 30 days, after which it automatically expires. Even if your patient’s email account is compromised, __no confidential or medical data can be accessed after this period__.   ###### Ensure compliance and peace of mind With OneDoc Invoice, your invoice transmissions comply with __nFADP and Swiss security standards__. You avoid sending sensitive data by email and meet your legal obligations without extra effort. ## Send invoices to your patients, securely With OneDoc Invoice, you can send invoices to your patients in one click, securely.

OneDoc Invoice simplifies and secures the sending of invoices to the Third Party Guarantor (TG). Your patients receive an email containing a secure link to download their invoice, protected by two-factor authentication via an SMS code. This ensures that only authorized persons can access sensitive data. In addition, links to invoices automatically expire after 30 days, further enhancing information security. This method complies with Swiss legal requirements (nLPD), allowing you to meet your data protection obligations while providing a smooth and professional experience for your patients. #### How can patient data confidentiality be guaranteed when sending medical invoices? With OneDoc Invoice, invoices are never sent as email attachments, which avoids the risks associated with unsecured email. Instead, your patients receive a secure link to access their invoice via the OneDoc patient portal. This link is protected by two-factor authentication (SMS code) and automatically expires after 30 days. These precautions ensure that medical data remains confidential and protected from unauthorized access. #### Is it possible to customize the cover letters accompanying invoices sent to patients? Yes, OneDoc Invoice allows you to customize the cover letters attached to invoices. You can create templates tailored to your needs, including important information or specific messages for your patients. These letters can be automatically generated in your patient’s language, ensuring clear and professional communication. ##### About OneDoc - [Our Mission](https://info.onedoc.ch/en/our-mission/) - [Privacy policy](https://privacy.onedoc.ch/fr) -
