A certificate that lives online too

Each certificate carries a QR code linking to a clean customer-portal view. Customers can pull up the certificate years later from their phone, even if the printed paper is at home.

QR-linked portal

Each certificate has a unique customer-portal page reachable from the QR.

Hide value if needed

A workspace setting can hide the price on certificates — for gifts, weddings, or insurance flexibility.

One-click email

Attach the certificate to a templated email and send to the customer in one go.
