Small business software...?

HEy guys… one of my clients is starting a small business and I’ve been doing their website and database setup… they asked me about software to handle invoicing, inventory management, billing, record keeping, mainling list, etc. Basically some “small business” bundle… I told them I’d look into it for them and recommend something…

anyway Im looking… but I was wondering if anyone here had some hands on experience with any of the packages out there and could make a recommendation?? THNX!
