What We Do

Leading a successful professional service firm is an art. Running a profitable firm is a business. We understand this because our founder ran an IT Consulting firm for over 15 years. He grappled with the same challenges that professional service firm owners face today. How do I know what my employees are working on? How can I connect time and expenses to clients or projects for billing? What resources do I have available? How can I see relevant reports on the firm’s performance? The list goes on. The problems our founder faced drove the development of an AI-powered professional services automation platform specific to the needs of operational and financial leaders in professional services firms. We know that time tracking is more than timesheets. Time is information. We connect time with every part of your firm’s workflow so that all of the data you’ve collected with BigTime is the basis for metrics-driven reporting that informs your decisions. We live by our founder’s purpose - to help professional service firms combine the art of leadership with the business of being profitable.

Why Work With Us

At BigTime we foster a culture that values and listens to what employees have to say. We are a high growth company where each employee has the ability to make an impact and develop personally and professionally and grow from within.
