I had a client pay with Apple Pay on 4/2 and has a confirmation number. I have not seen the deposit into my account yet. Do you have any recommendations?

Payments processed via Apple Pay are deposited into your account on the next business day.
 
If you do not receive the funds within this timeframe, I recommend contacting our QuickBooks Payments support team. They have the tools to check the status of your payments safely and provide further information.
 
To contact support through QuickBooks Online (QBO), navigate to the Search tab, select Contact Us, enter your inquiry, and then choose either the Have us call you or Chat with us option.
 
You can also check this link for more ways to contact them and see their available hours: Contact Support.
 
If you have additional concerns, please reply to this post.
