A small business that is a government contractor doesn't have a lot of choices for DCAA compliant accounting software.  Most small businesses start by using QuickBooks®.  While QuickBooks® is a very good accounting system for a small business, it is not designed to meet DCAA requirements.  There are ways to make a QuickBooks® based system into a DCAA compliant accounting system (ReliAscent has been doing this for years), it involves integration of several different pieces.  The operation of this type of system can become cumbersome as the company grows in either employees or number of government jobs or both.  In the past, many growing small businesses looked to software such as the Deltek GCS Premier® product to accommodate the growth.  The Deltek product has been recognized as the "industry standard" for many years.  While this is a solution, some of the complaints from small business has focused around the age of the software, the cost of the software and the inflexibility and difficulty of use of the software.
