Depending on your Bank and what type of account you have, you may be able to download transactions from your bank. Chase typically supports Online Banking through QuickBooks. In order to set this up, you will need to go to your chart of accounts and edit the bank account. On the edit screen, there is a button for online settings. This will walk you through the setup of Online Banking. Some banks require that you submit forms approving Online Banking, others simply allow you to use the same log on information as when you access the bank's website.
Once your account is linked up, you can download transactions through the Online Banking Center (Banking > Online Banking Center). When you download transactions, QuickBooks will first try to automatically match up any existing entries in QuickBooks with what it has downloaded. These transactions will be flagged as "matched". Any transactions that QuickBooks is not sure of, will either have to be manually 'matched' with an existing transaction, or added to the register. When you choose to add to the register, you will need to specify the vendor name (as the bank's name usually doesn't match the one you have in QuickBooks) as well as what expense you want to allocate them to. After doing this a couple of times, QuickBooks will begin to remember the vendors and expenses, so the data entry speeds up greatly.
This however, is not a 'reconciliation' to QuickBooks, but when you do go to reconcile, any downloaded transactions will be automatically checked, so your actually reconciliation process should only take about a minute to complete.
