Case Study: Sum of All Numbers achieves $40,000 annual profit increase with Bill.com

How Sum of All Numbers Increased Profit by $40,000 a Year with Bill.com

Sum of All Numbers is a virtual bookkeeping firm of 18 employees serving 400 clients worldwide, primarily in healthcare and B2B services. The firm struggled with inconsistent, paper-based accounts payable—printing and mailing checks, fluctuating costs, late payments and fees, and time-consuming back-and-forth approvals—which hampered efficiency critical to their value-based billing model.

By adopting Bill.com for AP and bill pay (integrated with QuickBooks Online), Sum of All Numbers standardized processes, moved payments online, and implemented an auditable approval workflow. As a result, 90% of new clients now use their bill-pay service, Bill.com client adoption rose 600% in two years, the firm saved hours of manual work, eliminated unpredictable costs and late fees, and increased profit by $40,000 a year.
