customers From our customers

I am very pleased with our SolAce billing software and how easy it is to navigate. They have a great team who can train you to do billing even if you don’t have billing experience. Special thanks to Cathy, Gigi, and Skyler who always helps me out every time I have issues.

SolAce is awesome software. I absolutely LOVE it. For over three years I have used this software daily for multiple long term care facilities to submit claims to various MACs, Medicaid, and Medicare Advantage and Supplemental Insurance carriers. It is convenient, simple to use and far less costly than any Clearing House software I had explored. The ability to import from my Practice Management Software and Therapy Providers has reduced any RTP claims edits and denials are a thing of the past. Customer Support is “Johnny on the spot”, but terrific as they may be, it gets better - RARELY do I need to call. LOVE IT, LOVE IT, AND LOVE IT.

I think our medical office was one of the first to use SolAce in the mid 1990’s and we are still using it today for all of our electronic billing because it works ! It was simple for our staff to learn and it integrated easily with our accounting/billing program. It has been especially nice to know that the Axiom staff is there when Medicare changes something and they are right on it. They made the 5010 change a simple process plus made educational seminars available to us. Thank you to all the Axiom/ Ivertex professionals who have helped us for the last 15+ years.

I am a new client and was having a tough time getting everything set up just right. I had to make calls to CEDI and when I called back the rep I spoke with prior even helped the 2nd rep to make sure I got all the info I needed. They definitely work as a team. Within a short period of time they had my system up and running. I never could've done it without them.
