Quantum serves its market well, with the ability to handle large data requirements, features pulled from vertical solutions (like work tickets, inventory trend analysis, expanded assembly abilities, and progress billing), and support for up to 40 users. Peachtree Quantum was introduced a few years ago with an eye toward businesses that have outgrown the original Peachtree Premium Accounting-those that don't want to spend many thousands of dollars on midrange accounting software but still need more data capacity and sophisticated features.
