Hello, hva.  

If you want to make your bills as paid, you can manually record a bill payment. However, if your bill payments are posted to a bank or credit card account and wanted to match it to the outstanding bills, you'll have to connect through online banking. You can use this link on what you need to have to get started with using bank feeds.  Once you are all set you can see the ACTION column where you have the option to match the bank downloaded transaction to the ones you recorded in QuickBooks.  

You can also get an overview of your vendor transaction by running reports. It will help you see if bills are correctly paid and review if there are duplicates that can mess up your books. 

I'll be around to help if you have other questions. Take care!
