I think we're paying for a module that we don't need... does this indicate that we are paying for NetSuites Site Builder(?) bundle?

I've seen SiteBuilder appear in the base module description as "Basic eCommerce Site". Would be best to check your contract.

Is there a way for me to see that as the admin?

I requested a copy from our AP team.

Ah, I'll do that. We do all of our ecommerce through BigCommerce and I just want to make sure we're not paying for Suitecommerce since we have never touched it
