There are three ways a receipt can be issued in Cutting Edge:
1. Once a payment has been entered into an invoice, clicking on the Print button on the Invoice screen will bring up a dialog window that will allow printing a receipt with or without items present (A receipt with items should not be issued until the date of service has passed and the patient has paid their share)
2. You can also send a Receipt via the email/sms tools and preview the attachment there.
3. Finally if a patient pays an invoice via the Worldpay portal, they can enter an email address and receive a receipt to the nominated address. This is different to the above path in that the receipt will never have any items present. There is also a setting on the Provider Settings panel to control what kind of receipt the patient will receive: see below. The generic receipt option prints a receipt with details only about the current payment, no further context from the invoice is added, no remaining balance calculations etc.
