Company Profile



A Standard of Excellence Since 1982

Mainstreet Computers, Inc.

Mainstreet Computers, Inc. knows the glass industry inside and out. For over 30 years we have passionately introduced valuable business solutions for every glass shop to use as a platform for success! We are innovators and are constantly evolving our products and services to meet the software needs of customers - small independent shops to multi-store companies.

We started small in May of 1982. Owners, David Carnahan and Thomas Bowles, created custom programs exclusively for each individual client. In 1985, we had our first glass shop express interest in a glass specific program. That interest lead to the birth of our Glas-Avenue™ Software System and from that point on we have continued to focus on providing software solutions to simplify the day-to-day business operations of glass shops in the U.S. and Canada.

The increased use of the internet and competition within the industry created a real demand for our customers to have an internet presence, so in the early part of 2004 we opened Mainstreet™ Web Services division as another avenue to serve our customers. As technology accelerates, Mainstreet™ remains committed to discovering new, effective ways to put our experience and knowledge to work for you!

Today, we are North America’s leading glass software provider and we credit our customers for our success. Throughout the years we have listened and responded to the requests made by the daily users of our software. Our customers trust us to keep a watchful eye on the business climate and diligently work to improve our products and services to meet those ongoing changes. In addition, we provide support that is unparalleled in the technology industry!

Technology evolves to make our lives easier. In over 30 years of business, Mainstreet Computers has introduced many time-saving features to the glass industry by making use of the latest technologies available.



Our flagship product, Glas-Avenue™, is a comprehensive POS software package for auto, flat, and repair-only glass shops.
