You could try "Zipping" instead. We use a billing service that prefers to input their own data. (Not sure, why, but they're inexpensive and fast, so OK by us.) To transfer info, we print AC invoices and collections reports to html. Then "zip" that, scans of insurance cards, EOBs, payments, etc. etc. and email the one zip file. We zip them all into one file using "7-zip" (an opensource zipping program free from 7-zip.org), and use the AES256 encryption, and password protect it with a password shared with the billers. (Unless your biller uses 7-zip, be sure to set 7-zip to use the standard zip format not the 7z format.)
