With Hint's New Charge button you can quickly invoice employers and patients for one-off charges based on pre-determined Coverage Plans.
If you haven't already, please review Hint's tutorial on how to set up coverage rules. These rules automatically determine how a charge item is priced and whether it's paid for by the patient or sponsor. Once your rules are in place you can use the global charge modal from the patient screen to quickly issue and process for one-off charges.
