UDP has been helping telcos meet their diverse billing needs for more than four decades. Although our roots are heavily grounded with the rural Independent Local Exchange Carriers in Texas, our 43 years in the business have enabled us to grow with the telecom industry and all its transformations. Today, we provide End-User Billing, Order Management and Customer Care, plus numerous Access billing and Mediation services for communication companies of all kinds, large and small, throughout the United States.
