Quickbooks - workflow

Before you can reconcile to bank statement; you should do these first:

First, take care of A/R (accounts receivable).
In this order:
Enter invoice - process payment - move deposit into bank a/c.
(These deposits should agree with amounts as stated on bank statements.)

Second, take care of A/P (accounts payable).
In this order:
Enter bill - pay bill

Third, when reconciling to bank statement.
If you see other deposits and debit charges on bank statement, post the entries to the check register.

If you have problem reconciling; look at these 4 numbers to find where the error(s) are:
beginning balance, total deposit, total withdrawals, and ending balance.
