How We Help

Having experienced tremendous growth since its founding in 2002, Innvest Hotels began to recognize the need for a financial software solution that provided a wide range of utilities tailored to the hospitality industry. Innvest heard about M3’s hospitality-specific solutions from an industry peer in the U.S. and decided to make the switch to M3’s exclusive, cloud-based solutions in February 2019.
