Wholesale Transactions: How does everyone get paid?

[Ryan Marrs]

Hello all, 

I'm just getting started out with Real Estate Investing. I have a question about how transactions work for wholesaling. I understand the process up until putting the house under contract and assigning contracts, but when you find the buyer how do the two party's (Me and the seller) receive their payments. Are there two checks written or is there just one check written? If there is just one check, how are the payments separated so everyone receives their payments. 

Let me know if there needs to be more clarification.

Thank you
