Yes, but you are probably also worried about the many technical and legal issues listed above, and want them corrected before signing up, rather than negotiated in a series of conference calls and meetings with your legal team. You likely want to pay for this with a "credit card" and monthly subscription, rather than by passing them the fax number if your purchasing department.
