I have seen a number of requests for this type of feature coming from clients in the Asia Pacific region, and we are planning to add of a Parent-Child account feature into eCommerce. This feature will enable clients to pre-purchase courses, or pre-pay for a range of courses, which can then to access by users logging in with a "child" account.
Child account users would be enrolled in courses up to the value of the pre-purchase cap. Any enrolment requests over to pre-paid limit would be captured and a notification sent to the Parent account owner for approval and payment. Please look out for notifications as we progress work on this new feature in 2021.
