Allow me to guide you through paying vendor bills in QuickBooks Online.
First off, record the bill you received from your vendor. Once done, let's perform the steps below to pay your bills:
- On the left panel, click the +New icon.
- Choose Pay Bills.
- Select a Vendor.
- You'll see the available credit with the vendor you selected in the Credit Applied.
- Continue modifying the rest of the field to your preferences.
- Click Save.
