How to do our daily Expenses in quick book like Auto, guest food bill with out vendor

Hello, @md-srilakshmitra.

You can't create any expense transactions without a vendor in QuickBooks Online (QBO). However, you can create a dummy vendor to record your daily expenses. This way, you can track the bill payments that you've made in QuickBooks.

Let me show you how: 

1. Go to the Expenses menu and select Vendors.
2. Click New Vendor and create a dummy info for the vendor.
3. Select Save.

In addition, you can run a Transaction List by Date report in QuickBooks. This will you the list of all money you paid to a supplier/vendor for the year.
