If a customer's account shows it was paid but it never was deposited, how do you fix

Thanks for checking the payment in the Merchant Center, BJZS.

I'm here to help make sure the payment deposits to your bank account.

First, let me share the funding time for merchant transactions. Generally, credit card payment deposits take one to two business days. For bank transfer (ACH) payment, it will take two to seven business days. This article will give you more insights: Find out when QuickBooks Payments deposits your money.

If the payment hasn't been deposited after five business days, it's best to contact our Merchant Services Customer Care. They have the tools and resources to help you check the payment status.

Here's a relevant article for more details: Deposits FAQ.

Please reach out to me if you have any questions later on. I'm always happy to help. Enjoy your day!

The transaction never showed up in the merchant center under transactions.  The customer's account has a 0 balance and the invoice is marked paid.

Hi there, BJZS.

Posting of payment depends on the customer's mode of payment. If it's more than the usual turn around time, our Merchant Support Team can trace the transaction and check why it's not yet posted. Please follow these steps on how to contact them:

1. Open this article: https://quickbooks.intuit.com/community/Payments/QuickBooks-merchant-services-or-QuickBooks-Online-s...
2. Scroll down to the QuickBooks Payments support section.
