A group of accounting firm leaders shared their perspectives Thursday on how they identify potential firms for mergers and acquisitions.

Top 100 firm RubinBrown LLP has merged in the Business Manager LLC, expanding the firm’s outsourced accounting services in Denver, effective immediately.

Go to any accounting conference and you will immediately hear people claiming a 15+ percent increase in revenues through the implementation of a new service. Talk to any vendor looking to sell a product and they will claim success stories whereby their product led to 25 percent growth in a firm for four years straight.And then a light bulb went off in my head. These people are scrounging out the 3 percent increases that I am seeing. They haven’t doubled in size, they haven’t found the secret sauce, they are tooting their own horns because it feels good when others think highly of them.
