When you go to Reports at the top of the page select Transactions. Here on the right side you will see your current balance, and how much funds are credited to active contracts. You will have a detail table of all of the transactions also.
I have balance in my freelancing account near about 124 $ and I want to hire some freelancer with my client account (email id is same for both account).
So How I can use the current balance to pay the freelancer
I checked and it looks like the funds for the previous week are in the "In Review" tab of your Reports page. This represents hours logged last week that are now under review by your clients. Clients have 5 days to review your work diary. After that, the funds move to 'Pending' tab that represents the standard security hold period in which funds cannot be withdrawn. Please note that hourly payments are in the security period from the time the client review ends on Friday to when the funds are released on Wednesday. You can check this help article for more information.
If however, you were referring to your 'Work History', please note that only jobs on which payment has been processed are displayed on freelancer's profile.
re: "I am not in a position to check my bank account to see if the funds are coming out of my bank account."
Learning how to check your bank account balance would be worth your while.
How do I know if I 'logged' in with the correct referral link in the e-mail to get the credit? I posted a job and hired a contractor. When do i see this credit? Is there some way I can know beforehand before releasing funds?
