Computerized Office Services was developed in 1995 to service small businesses and healthcare practitioners. We are backed by over 25 years of experience in the billing, bookkeeping and office services fields. We are a small company focusing on small businesses, healthcare groups and single practitioners. Our goal is to provide the services they need in a package developed specifically for them. We do not require a minimum number of patients nor charge a minimum fee per month. We take training courses through Medicare University to keep apprised of the changes in claim submission required by Medicare.
