OSAS is the largest installed accounting package in the United States
and has been available since 1981.
HKS has been an Open Systems reseller since 1984 and we have
many long term satisfied customers. As a qualified dealer and installer
we have been manufacturer trained to install, service and support this
software.
OSAS can be either single user or networked and comes in modules
for selecting the best client configuration; you purchase the modules
that your business needs.
Resource Manager is required for all installations, and you can
mix and match modules at any time.
One of its unique features is that when you purchase the license
to the program you also get the source code, making customization
very easy. There are a substantial number of third vendors whose sole business
is making and selling highly customized enhancements to modify the system
for various industries or needs.
