What is OpenOps?
OpenOps is a complete system for contact management, work orders, scheduling, proposals, accounts receivable and inventory. OpenOps is currently based around the custom install market but will most likely be translated for any other service based industry.
Since OpenOps is open source the current version is absolutely free! All you need is Apache webserver with PHP support and a MySQL database installed. For those who are not so adventurous hosting solutions will soon be offered.
