Invoicing Overview

Estimated reading: 5 minutes

Invoicing is the process of documenting the sale of goods and services performed on a patient and requesting payment from a client. It’s used for record-keeping, accounting and taxation purposes. During the invoice process, Cornerstone updates the reminder information and the patient’s medical file. It also generates any departing instructions, special actions linked to the invoice items, and prompts for call back note entries.


  • Once posted, invoices cannot be modified.
  • Reminders are updated and departing instructions display in history once an invoice is saved or posted.
  • An invoice can only be accessed by one workstation at a time.
  • You must have at least one invoice item on an invoice to save or post it.
  • Address all messages that pop up during invoicing to ensure charges are not missed and patient care is not impacted. This includes:
    • Item transfers from the patient visit list (PVL).
    • Resolving not requested diagnostic results. Note: Unresolved results do not display in the patient history.
    • Checking out patients from their boarding reservation.
  • You can invoice an inactive client, but a written off client cannot be invoiced. Reinstatement is required, with security access.
