Can't get my cc state to reconcile

Let's see if I have this correct:

You set up a BOA credit card that shows up on the chart of accounts as type = credit card (other current liability).

You paid a vendor with the credit card and you entered the charges using the "enter credit card charges" under the banking menu.

So far, so good.  Now, when you entered those credit card charges (let's just say you paid Staples $100 for printer paper on August 5 using your BOA credit card) you followed the procedure.  So the entry on the credit card screen was dated August 5th, the vendor was Staples, the amount was $100 and the expense account was Office Supplies.

You follow this procedure for the rest of the month.  Now the statement comes.  You would go into the banking menu, reconcile and pick the credit card account.  Enter the statement date and the ending balance.  Check off the entries that are on the statement.  They should balance out.

If the statement doesn't balance, you are either missing some activity, didn't enter the beginning balance when you set up the credit card or have voided or deleted some reconciled transactions (which probably isn't the case since you say you haven't been able to reconcile).

When you pay BOA, you would write a check to BOA and the "expense" account would be the BOA account from the chart of accounts (the credit card "other current liability").  Those payments will then show up on the reconciliation screen.  I don't recommend that my clients add a bill to be paid because when QB does the accrual to cash conversion it only picks up a proportional share of the paid balance on the credit card for the period.  (You can skip the add a bill portion of the reconciliation process by clicking on Cancel when that option comes up).  So if you enter $10,000 worth of expenses in December and only pay $500 on the balance due, you will only see $500 worth of expenses on your December P & L and the rest will expense out as the balance is paid down the following year.

I hope this helped explain the procedure to you.  If it answered your questions, please mark as solved.  If not, please ask more questions.
