I have had good success with our billing company. We ftp PDF format billing sheets out of AC to their server as they are 5 hours away in Detroit.
Medical Practice Made Perfect The owner's name in Vonda. Although it/we are in Michigan, they may serve Indiana as well. 5.5% of whatever they collect + a postage fee to send out the patient invoices.
I have no relation to their company or services other than being a customer.
