CHEERS 45L and their team is always very thorough and wonderful to work with!  With their help, LGI  was able to qualify thousands of homes for 45L tax credits.  I would highly recommend CHEERS 45L and the service they offer.”

“Delivering 45L certificates generated with Department of Energy approved software was important to us. We looked at other competitors and chose CHEERS 45L for the cost, self-service & full service options and the team’s professionalism.”

“The CHEERS 45L self-service web app is simple, intuitive and easy to use. Importing projects was seamless; I was quickly able to find several homes that passed the tax credit with CHEERS 45L which had previously failed in other 45L software. The support staff was incredibly responsive. I highly recommend using CHEERS 45L for the 45L tax credit.”
