A typical visit moves through the tabs in this order:

  1. Examination — record findings (and mark teeth on the dental chart, for dental clinics).
  2. Prescription — write the prescription and print or share it.
  3. Sittings — record the treatment done and any payment taken this visit.
  4. Billing — create the bill and settle payment.

You don't have to use every tab every time — but this order matches how most clinics work.
