On my account balance it says i have no money when i just finished a gig a few days ago??
What part of the Revenues page are you referring to as your balance? If you go to https://www.fiverr.com/users/designs151/balance/sales there are multiple columns that should show the phrases your funds could be in. Are you saying there is no money showing on that page anywhere? (You can also get to that page by clicking Selling and Revenus.)
In the following Fiverr article you can get every details you want about revenues! There are so many articles that may help you very much for sure. Please make sure to grip with them.
Just wait 14 days after the order is marked as completed, and then it’ll show up as an available fund.
