Hi there, @ChristinaL.

There's no specific time as to when the QuickBooks sends the email of the scheduled reports. For more information about setting up scheduled reports, you can check out this article: Set schedule and email information for a memorized report.

I've also this article for your future tasks with QuickBooks about managing your customers' payments: Record invoice payments in QuickBooks Online. This contains tips on how to use Undeposited funds. By the time you're going to deposit those payments to your actual bank you can merge it into one transaction. This will help you match these transactions when reconciling your account.

I'll be one comment away if you have other concerns or questions. Take care and have a wonderful day ahead.
