How can I turn on the "Bills" feature in QB online?

Welcome to the Community.

I'll share information about the features included in QuickBooks Online.

QuickBooks trial versions include the same features as the monthly subscription.

The basic features included are operating bills, payments, and organizing receipts. It also includes other essential accounting functions like manipulating reports, creating and sending invoices, and tracking GST and VAT. 

To create a bill, follow the steps below:

1. Click + New.
2. Choose Bill.
3. From the Vendor ▼ dropdown, select a vendor.
4. From the Terms ▼ dropdown, select the bill's terms. It is when your vendor expects to be paid.
5. Enter the Bill date, Due date, and Bill no. as they're recorded on the bill.
6. Enter the bill details in the Category details section. From the Category dropdown, select the expense account you use to track expense transactions. Then enter a description. Tip: You can also enter specific products and services in the Item Details section to itemize the bill.
7. Enter the Amount and tax.
8. If you plan to bill a customer for the expense, select the Billable checkbox and enter their name in the Customer field. Learn more about billable expenses.
9. Select Save and Close.
