Would LOVE to link a payment plan to said invoice. We have many patients who can not afford a plan out right and do financing. They will complete the payment plan but still have an "outstanding" balance that does not go away. When running reports it's a NIGHTMARE to try and figure out what outstanding invoices are truly outstanding or not. There is also not a way to mark an invoice as paid unless you input an amount. The payment and invoicing system could really be improved.
