New Business Revenue Split Discussion

In our team, we have four sourcing consultants and a newly hired 360 recruitment consultant. The 360 consultant has begun engaging in business development activities. However, she expressed that when she secures new business that she cannot fulfill herself, the roles are passed on to a sourcing consultant. She believes that the revenue split should be 30% for her and 70% for the sourcing consultant. Furthermore, she thinks this arrangement should apply for all new business she brings in and for any placements she cannot fill for a period of 12 months after securing the business.

Is her perspective valid?
