Either the Buyer or Seller may start a new escrow transaction from the Member Account. The fully automated system instantly adds the new transaction to both parties accounts. If one party doesn't have an account, the system will invite them to join.
From the private escrow status page, the Buyer submits payment to (My domain) admin for safekeeping. When payment has been submitted, the system updates the status of the transaction and instructs the Seller to ship the item. Once the item has been shipped, the Seller informs (My domain)from the status page.
The Buyer receives the item and upon confirmation, the Seller receives payment. Both parties are protected from fraud every step of the way.
So you are to build two sides, which is the user side and the admin side. reference domain is escrow.com
