A warm welcome to the Community, YasminHussain.
You can ask your client to enter the invoices and bills himself and review the transactions when you accessed their account. However, if you need to ensure that the transactions are accurate, ask your client to keep track of them and record them accordingly into QuickBooks on Friday.
