How it works

From template to signature.

  1. Choose a template

    From the template library (treatment agreement, privacy consent, fee agreement …) or upload your own PDF with signature fields.

  2. Send to the patient

    Email link sent through Centi with your practice name and a personal greeting. Replies go to your practice address.

  3. The patient signs

    Patients sign in the browser on their own device. The audit trail is captured automatically.

  4. PDF lands in the record

    The signed document is linked automatically to the patient record — searchable, verifiable, exportable.
