Once you’ve posted your gig, it will be published publicly on the task feed.
Service providers who are interested in your gig can then make an offer.
Check out your offers and think about which service provider is best suited for your task. When you've made a decision, you simply need to accept their offer.
To review and accept offers, login to Dashboard -> Gigs -> Choose the gig.
Payment is debited from your payment method at the time you assign someone. It is securely held in escrow by GOHISO until the task is complete, meaning you're still in control of the payment and when it gets released to the service provider's bank account.
