Accounting Systems and e-commerce

I have a client who is looking to purchase a new accounting system such as
SAGE MAS 90 or similar. Our goal is to select a system which will easily
integrate with a new e-commerce site we will build after the new accounting
system is installed.

Does anyone have any suggestions or opinions on MAS 90 or other products.

We will also be looking for a consultant to aid in building the e-commerce
so if anyone is interested send me your contact info and list of sites we
can look at.

Thanks

Ron Fuhrer
