My customer made 2 deposit payments yesterday. The 2nd deposit showed up in my account already first payment they made still hasn't shown up, 2nd already has???

Hi, @jraemy25. I'm here to provide information about your delayed deposit payments in QuickBooks Online (QBO).

Within 2-3 business days, funds should arrive in your deposit bank account. This is because it varies depending on when transactions are entered and which financial institution is used to deposit transactions. It also matters how long your bank takes to verify and process electronic deposits.

If the payment is still not deposited within the specified period, you can contact the QuickBooks Payments Support Phone Team to verify the deposit status. 

I've also included an article that can help you learn more about the delayed deposit in QuickBooks.

You can also check out this link to help you find out when QuickBooks Payments deposits your money.

If you have other concerns about how long the QuickBooks Online deposits appear on your bank account, let me know in the comments below. I'll be glad to help. Have a great day!
