The closing documents for the company can be found on the Operations and Accounting tabs. You will find the funding invoice in the Operations/Funding section. It is created upon the accrual of funds to your balance. If you need to receive the funding invoice before the actual funding, contact your manager.
The invoice with the specified service and the amount of payment is in the Operations/Charge section. It is created after you accept the freelancer's job. At this moment, funds are debited from your balance and credited to the contractor's balance.
