Any new Accredible account can create certificates and badges for up to 20 people. You can create and issue digital badges, digital certificates, or a credential that has both a badge and a certificate - your trial allowance doesn't restrict what you can issue in any way. Credentials you issue will not be deleted, so if you want to try it out, and the come back to Accredible later, your credential data will be waiting for you.
If you like issuing certificates with us or decide you want to access to some of Accredible's other features (like hosting your credentials on your own domain, adding team members to help you create certificate designs and credentials), you can upgrade to a paid plan at any time, starting at $20/mo.
