Best software to integrate service call management and bookkeeping

Hi…

I know there’ll be as many opinions as readers but I’ll ask the question anyway.

Is there an inexpensive (or better yet open source) product that integrates service call records/invoicing/retail sales with a basic accounting package (i.e. AR/AP/GL and maybe inventory).

I’ve got about 6 different products going at the same time and its pretty inefficient.

What’s your experience with this dilemma.

Thanks for your opinions.
