If this were something that were being purchased off-the-shelf, it'd clearly all be the responsibility of the purchaser. When it's priced differently depending on how the customer plans to use it, and it's sold only through a consultative process, I'm not sure it's so clear. In order to determine their pricing, the sales team demands to know how the customer is using it... so they absolutely arguably do know.
