On the QB app, I'll search for a Customer, select Activity and then it's blank. Is there a date range filter? I want to see their previous invoices.Thanks.

It's great to see you here in the QuickBooks Community! I'm here to share steps to filter your customer's invoices by date within the QuickBooks App.

Here's how: 

1. Click the three horizontal lines at the lower right corner of your screen.
2. Select Invoices, then click the Search icon and enter your customer's name.
3. Below the search bar, click on the Date to filter.
4. Pick your desired date range to display the invoices.
