Potomac Climate Systems Inc.

Potomac Systems has historically provided application and network integration services to the commercial marketplace. Put simply, it is about building software for you when nothing off the shelf fits.

The natural audience is companies with a specific process to automate. As a very small company team themselves (1 to 10 people), they tend to serve customers of a similar scale best. You will probably talk to the people who build it, which is great until you need 24/7 support.

Potomac Climate Systems Inc. is based in Arlington, Virginia. Their site is potomacsys.com.
