This requires you to use Favrit ePOS, "Open bill" and "Invoice as a payment option". If you don't have access, contact your customer success manager or Favrit Support.
This article assumes you already know how to use ePOS for making sales and are familiar with Open bill.
In the Open bill menu, you can choose any table and click "Pay". If "Invoice as a payment option" is enabled, you will get the option to choose "Invoice". The system will ask for a customer reference. We suggest adding the name of the group, the booking number you already had, or any other reference.
The list of invoiced customers is then available as a report in Admin.
You have to ensure to invoice your customers yourselves. Favrit does not capture contact information, do credit scores or collect the money from the guests.
