Brokers commissions and accounting entries

Brokers commissions and accounting entries

Hello,

We are brokers, so each broker gets a commission on each invoice we issue through zoho books.

The commission % differs from one broker to another broker, it differs based on the invoice, 
Example:
- Invoice A, 30%commission for Mike
- Invoice B, 20% commission for James.
..and sometimes the commission could be split between two brokers as well.
Example
- Invoice C, Mike will get 10 % and James will get 20% 

All these commissions will be accumulated and distributed to brokers once a year,

Can you please assist us and inform us how to create such commission setting and how to record them as payables to be accumulated in accounts to be paid later one.
