I'm a newbie here, and I'm wondering about my account's balance.
I had earned some money from my client.
It's shown on my profile here, but my balance is still zero.
Is it a normal situation?
Go to your reports (see the Reports button on the header) and that should tell you what's happening.
Basically, it depends on when the work was completed and whether it was hourly or fixed price. If it was this week then it will be a couple of weeks before you get your pay. At the end of the week (Sunday UTC) the money will be moved to "In Review". This is the time that the client can check your hours and make sure everything is okay. The client has five days to do this. If no dispute is placed, then on Friday (actually the end of Friday) the money will go to "Pending". It will stay there for another five days and then become availabe.
If it's fixed price, then I think the time you get your money depends on if you have to submit requests for milestones to be paid or not.
