There are two methods for paying bills in QuickBooks. The first and simplest is to enter the bill as a check, just like you do in your personal checkbook. The second and generally best method breaks the process into two parts: entering the bill and then later paying the bill. This blog deals with the latter. For a comparison of the different methods, see Entering Bills vs. Writing Checks.
The first step in this two step process is to enter a bill. You can enter the bills when you receive them, though I recommend putting them in a pile and then processing them on a regular basis, such as weekly, rather than right when you receive them. Regardless, to enter bills open the Enter Bills window from the Vendor menu.
Except for the check number, which will be assigned later, fill the bill out exactly as you would a check:
Once your bills have been entered, they show up in QuickBooks as accounts payable. QuickBooks makes it easy to wait to pay them until they are due, thus enabling you to keep your cash as long as possible. When you pay them, QuickBooks debits the accounts payable account and credits cash, so it is easy to see exactly what bills you have received but not yet paid. To pay your bills, open the Pay Bills window from the Vendor menu.
In the QuickBooks Pay Bills window you can choose whether to see all bills or just those due by a certain date. Select the ones you want to pay, the payment method (check or credit card) and whether or not you will be printing them, and the payment date to print on the checks, and then click Pay Selected Bills.
If you use printed checks then the last step is to print your checks.
