Deposits from customers when quickbooks says it will clear tomorrow will that be available at midnight tonight?

It depends on the product you're using and the payment type you're processing, Chris. I'll go over some details to explain it further. 

When QuickBooks indicates that a deposit will clear “tomorrow,” it generally means the funds will be available in your bank account the next business day if processed before 3 pm PT. However, this doesn’t necessarily mean the funds will be available exactly at midnight. 

The availability of funds can depend on your bank’s processing times and policies. If you need the funds urgently, check with your bank to understand their processing times.
