Software should work together and make your life better ...

Since 1980, Attorney Computer Systems has been working to help small and medium sized law firms “Worry Less and Practice More”. The founder of Attorney Computer Systems, Paul Purdue, grew up in a family of attorneys.  Paul has always been fascinated with how systems and people work together to form a harmonious infrastructure, which together produces work for the practice and a quality of life for those in the practice. 
Whether you’re looking for billing and accounting, practice management, document management, or creative API integration with third party applications, Attorney Computer Systems takes a holistic approach to clearing away obstacles to get your infrastructure flowing like a well-oiled machine. We work with you on the initial purchase of your software, its implementation, customization, and optimization. We also provide you and your staff with ongoing training solutions.
Our philosophy of believing we must have a master level depth of knowledge in the areas we specialize in is what sets us apart from other solution providers who may take a “jack-of-all-trades” approach.
