A certificate of attendance confirms someone was present; a certificate of completion confirms they finished a defined set of work. Here's how to tell which one your event actually needs.
A certificate sent to a no-show quietly weakens every certificate sent to someone who actually attended — here's why the check-in list, not the registration list, should drive who gets one.
Sending certificates after a workshop doesn't need a recurring plan — upload your check-in list, issue one PDF per attendee, and pay once for the batch.
