Yes, through Account Members: an account manager can add you as a member and turn on "You pay this member subscription" so their card is charged for your subscription purchases automatically, or turn on the per-module checkbox under "Allow member to purchase outside included subscription (Manager pays)" for other ordering modules. When shopping under that arrangement, the cart clearly labels it — «You are paying for your member «name»» (for the manager) or «This is being paid by your account manager» (for the member).
