We are finding that patients are getting a bit confused (and workers comp insurers very confused!) with the layout of receipts, especially when only part of the invoice has been paid.
It would be good to have a simpler layout with the charge amount and payment amount on the same line. Or even three columns - charge, payment, remaining. At the moment we are printing and highlighting, and also writing an explanatory note, to make sure that there are no errors in payments as we have had before.
