Commission Structure: What’s Your Split Between Recruiter and Account Manager?

In most agencies, commissions are typically divided between Recruiters and Sales/Account Managers (AMs). The AM usually brings in the business, while the Recruiter handles the candidate placement, so it’s common for the two to split the billing in recognition of their collaborative efforts. If your agency operates in a non-360 model, how do you structure this split? Is a 50/50 division reasonable, or do you lean toward a 70/30 distribution? We’d love to hear your thoughts!
