Hi @allopart,

I'll answer this query about custom fields for your expense transactions in QuickBooks Online (QBO).

The Custom form styles feature in QBO is exclusive for sales transactions. I understand that the ability to customize expense transactions is essential to your business. With that said, we'll take note of this.

On a different note, if you want to create custom form styles of your own, check out this article: Import custom form styles for invoices or estimates. 

Do you have other questions about your QBO company? Place them in the comments below, and I'll take care of them for you.
