I have bad experiences in the past where buyers have not paid – how can I make sure I get paid promptly from the buyer?
We have an escrow feature on our website. Before you start the work ask the buyer to put money in the escrow (they can do so by logging into their account) and this way the buyer can transfer money to your account, when you finish the project but the buyer cannot retract the money and if necessary site admin can help sort things out if any issues arise later.
