Hi, Welcome to the forum. Using escrow is the best practice to avoid the thread of scammers.
How Escrow works?
# 1. Buyer or seller requests for this escrow service.
# 2. Escrow confirms the trade details by contacting buyer and seller. [or rejects the request]
# 3. Buyer sends funds to escrow.
# 4. Seller sends the goods to the buyer after escrow's confirmation.
# 5.A Buyer confirms the receipt of goods or service and informs the escrow.
# 6.A Escrow release the funds to the seller.
It is a responsibility of the seller to meet buyer's expectations and buyer's responsibility to ensure the goods or services are as per buyer/seller agreement.
It is a responsibility of the buyer and seller both to give the correct information about the deal, escrow will assume the information is true after getting a confirmation from the buyer and seller.
How Dispute works?
# 5.B Buyer Files Dispute Request.
# 5.B.1. Escrow holds funds with him.
# 5.B.2. Escrow allows buyer and seller to represent their case (72 Hours Max).
# 5.B.3. Escrow cross checks the evidence produced by both the parties.
# 5.B.4. Escrow examine the situation critically.
# 6.B Escrow refunds to the buyer in case of the situation if it's in buyer's favour.
Escrow releases the funds to the seller in case of the situation if it's in seller's favour
A benefit of the doubt will be given to the most trusted member in the deal.
Past trades of both the parties will be considered in this case.
Buyer and seller can mutually cancel the trade before step 6.A
In such case, step 6.B will be performed by the escrow
