More About Our Company

A Brief History of Our Company

Tab Service Company is a Chicago-based, family-owned and operated business founded by Robert Lambert Sr. in 1960. We began as a bookkeeping and data entry service firm, and over the years, have expanded our service offerings as technologies have changed. Today, we help our clients increase task efficiencies via automated solutions to formerly manual processes.

Our data processing services are used by organizations with big data needs that seek assistance with projects such as analysis of survey response trends and the capture of high-volume customer leads for marketing campaigns. We also provide online tax forms processing services to a range of businesses and institutions of higher education throughout the country.

Tab Service Company has evolved into a one-stop shop for business processing and outsourcing services. Our goal is to help our clients manage time-sensitive and data-centric projects and administrative functions — safely and securely — so they keep their organizations running smoothly.
