We are committed to helping the field service industry be more successful.

Aptora is the longest running flat rate software company in America, under the same ownership, same EIN. Flat rate companies have come and gone. Some have been sold and sold again. We sold our first copy of Flat Rate Plus in November 1996. James R. Leichter, known commonly as Mr. HVAC, has been the president and owner ever since. We have deep roots in the world of flat rate pricing.

Now Flat Rate Plus Online® is an easy to use and very affordable web app. We took the best of Flat Rate Plus for the desktop and put it on the cloud. It is easier to use, and jam packed with many more features and benefits.
