How can you make a secure transaction over the Internet?

Question

Electronic commerce

Hello, I need to buy the services of another person via the Internet.
How can I implement this safely, is there a service or some way so that they cannot throw me?

Answer 1

They can also throw under a real contract, so it depends more on the specific person.

Answer 2

You need a third party that both you and your counterparty trust, who can objectively assess whether the service was provided.
Freelance sites can do this.
