Automatic Business Computing is a privately owned payroll firm that started in the heart of Silicon Valley in 1980. It was founded by Grant Shaw, an engineer at Hewlett-Packard with an entrepreneurial dream. His sons, Michael and David, have followed their father's lead into the business and now manage the company and daily operations.


Our offices are now in Rocklin, California, strategically located to the Sacramento and Bay Area markets. With our technology, we can and do serve customers all around the United States.

Our four decades of experience gives us a practical and professional advantage which is difficult to replicate elsewhere. We have helped thousands of small businesses successfully fulfill their employment obligations efficiently, accurately, and reliably. We take pride in our associations with major brands, like McDonald's, Subway, and Waddell & Reed, but we value equally our many small clients who excel in their respective markets. We see ourselves as part of your team and value the relationships we have, many of which have endured for more than 20 years! We offer all this at reasonable prices, often significantly more affordable than big, national corporations. We offer the same technology they offer, but we couple it with much better, personal service. To them, you are another one of their tens of thousands of accounts; to us you are our livelihood. With them, you get fancy marketing; with us, you get fancy service. Our drive is to listen to our clients' workforce management needs and then help them achieve their goals with the tools and support necessary for success.
