Can i find a missing payment which has been deposited into the bank but not seen in the app?

Hello there, @wordsmadealive-g. I'm here to ensure you'll be able to find the missing deposit in your QuickBooks Online (QBO) app. 

To start, we can perform some troubleshooting steps to help you find the transaction. Refer to the following steps below.

In QBO mobile app:

For Android

1. Navigate to the Settings icon.
2. Next, select Refresh Data.
3. Then, choose Yes.

For iOS

1. Tap the menu icon at the top right part of the screen.
2. Then, choose Help & Feedback.
3. Next, click Refresh Data and select Refresh.

Once done, check if you can now see the deposit. If the same thing happens, let's review your Undeposited Funds Account. Maybe that's where the payment was placed. Here's how:

1. In your QBO account, click the Gear icon and select Chart of accounts.
2. From there, look for the Undeposited Funds Account.
3. Select the Account History link.
4. When opened, check if you can see the missing deposit there.

For reference, feel free to check this article: Find missing payments you want to deposit in the Bank Deposit window.

On the other hand, you can also manually import transactions into your QBO account via CSV files. For a detailed guide, feel free to check this article: Manually upload transactions into QuickBooks Online.

I've also attached this helpful resource that you can check to have a reference in balancing your account using the reconciliation process: Reconcile an account in QuickBooks Online.

Please let me know how the recommendation goes. I'd love to hear updates about the outcome. I'm always around here in the Community to assist you further. Have a good one and take care.
