90% of of our new clients use Sum of All Numbers for bill pay. The number of new clients using has increased by 600 percent in the last two years. With, Sum of All Numbers has increased our profit by $40,000 a year. has also eliminated the hours we would spend on back and forth such as who is going to print the checks and how it will be done. It has made things more efficient, which is important for a firm that bills based on value.
