To generate a facility invoice, you will have first needed to have added Locations that your practice provides services at, as well as any service rates that may be applicable to your practice or even the specific facility itself.

After completing sessions at these facilities, as a billing administrator, you can then generate a facility invoice. Go to Billing-> Generate an Invoice

From here, you can select which dates of service will be included on this invoice, and for which location.
