Is there a way to do a key word search through all of my invoices?

Thanks for reaching out to the Community, springtwpconstab.

QuickBooks Online has an Advanced Search feature that makes finding invoices quick and easy. Let me walk you through on how to do it:

1. Click the Magnifying Glass.
2. Select Advanced Search.
3. Choose Invoices for the transaction type drop-down.
4. Change the filters to look for the type of data you want.
5. Click Search.

You can also customize the results by clicking the small Gear icon above the search results to choose the columns you want to display.

I'm also adding this article about searching for transactions in QBO for your reference: Search for transactions
