The first time you sign in, Harness walks you through a few quick steps to set up your basic information. None of this is permanent. Change any of it later under Settings.
Set a rate on the student directly, or create reusable named rates under Settings → Rate presets and attach them to students. A student with no rate still works, but their charges come through at zero until you set one.
Bill the account for its charges. Pick the account, choose which charges to include, and send. Harness emails it to the account’s contacts.→ Send an invoice
