Someone else above/below commented "Marketing --> Product".
I see it that I have a problem, someone solves that problem. I pay $$ per month. Everyone is happy.
I'd say "solution" or "product" and not get stuck on the technical details (for/to which I agree with you but 90% of the people don't care).
