Can a quantity column be added to a bill?

Welcome to the Community!

A quantity column is there by default when you create a bill in QuickBooks Online (QBO). 

If you can't see the quantity column, you'll need to turn on the Item details table. I'll guide you on how.

1. Go to the Gear icon.
2. Select Account and settings.
3. On the Expenses tab, click the Bills and expenses section.
4. Toggle the Show Items table on expense and purchase forms to turn it on. You can see the screenshot below for your reference.
5. Click Save, then Done.

I'll leave this article with more information on tracking and recording your bills: Enter and manage bills and bill payments in QuickBooks Online.

For your future reference, here's an article on recording a bill payment using a check: Record a purchase, payment or bill using a cashier's check.
