The advantage of using a dedicated escrow account is that you only release the funds to the seller once you are happy with the product or service provided.
Whilst the funds are in your escrow account, you are able to raise a dispute if you face any issues. It is important to note that you cannot raise a dispute regarding funds that have already been released. When the funds are released, they are sent directly to the sellers bank account and cannot be recovered.
This is why you should only release the funds when you are happy with the standard of the goods or service provided.
