Configurator product linking to Sage 300

We have a customer who sells highly configurable products.  They're interested in looking at add-on products that would help them do this and push the results to OE.  We're looking at CIS Configurator to start with but they would like to have other options if they exist.

They do not have a manufacturing "product" in place (they DO have a home grown manufacturing system) and would be open to putting one in if it is a requirement/byproduct of the configuration software.

Any suggestions?
