If you're utilizing the checkout in the Online Calendar, you can add a No-Show Fee as an "item" in a clients cart under the Additional Items table.
This No-Show Fee will always be in the client's cart, so even if they do not have a Card on File, you can include it in the balance due for their next appointment.
For example: Client Jessica no-showed her September 6th appointment but has a future appointment on September 14th. Type in the No-Show Fee on the spot ("No-Show Fee - September 6th") and assign the no-show fee you wish to charge ($50) so it is in her cart for her next appointment.
Note: You do not need to create the No-Show Fee as an item in the Clover Inventory App - You can just type it in on the spot and add the fee amount.
You can refer to the client's Transaction History (Client Profile in Online Calendar > Transaction History) to keep track of the No-Show Fee that was added to the cart or add in a Client Note so all staff are aware of the No-Show Fee.
