A customer just paid an invoice, but the funds are not showing.

A warm welcome to the Community space, Kimberly. Let me help you identify why your funds aren't showing when you receive invoice payments.

If this is your first time receiving invoice payments, your funds will be deposited within five business days. The first deposit may take longer as QuickBooks is processing your account. However, once your account setup is complete, your future payments will be deposited within two business days.

If you process payments in QuickBooks Online (QBO), here's how you can check the status:

1. Sign in to your QBO account.
2. Go to the Sales tab and select Deposits.
3. Choose the bank deposit you want to review.

To check the status of your payment transactions from the Merchant Service Center, here's how you can track:

1. Log in to the Merchant Service Center.
2. Select Deposits in the Activity and Reports field.
3. Enter the specific date range and select Search.
4.  A new window will appear displaying the results.
5. To view details, simply click the triangle located on the left side of the line item.

Additionally, you may follow these steps to record invoice payments to mark them as paid in your QBO:

1. Log in to your QBO account.
2. Click the + New icon.
3. Select Receive Payment.
4. From the Customer dropdown, choose the specific customer.
5. Select your Payment Method from the dropdown.
6. Choose your bank to put the payment into from the Deposit To dropdown.
7. Enter the amount your customer paid from the Amount Received field.
8. Check the box for the invoice you're recording in the Outstanding Transactions section. 
9. Click Save and Close.
