Buyer agency fee/compensation wording for contracts

[Kate Barry]

I know my worth as a buyer's agent.  I am worth a full 3% when I represent a client.  Sometimes the listing brokerage does not offer a full 3%.  In this case I do ask my buyer clients to bridge the gap in the difference.  So if the listing is offering 2.5% , the buyer will pay 0.5%

What is the best way to word this in a buyer agency contract?

@Steve Morris 95% really? LOL.... You must be joking. Unjust commission claims are EXTREMELY RARE. Any agent who is willing to work with a buyer without a contractual agreement is a complete fool. If you can't value your own work, why would a buyer?
