Welcome to the Community, Augen. I'd be glad to provide some details about setting up QuickBooks Payments.
When setting up QuickBooks Payments, it is crucial to provide your Social Security Number (SSN). This requirement stems from IRS regulations, which mandate that businesses collect and verify this information for tax purposes. In your case, since you are using the SSN of one of your employees, it is important to ensure that the SSN is accurately entered. Any discrepancies could lead to issues with the setup process and might delay your ability to accept payments.
About your customer payment, if you are referring to automatic deposits from customers, one possible reason you are unable to make deposits is that the Payments feature has not yet been activated in your QuickBooks account. In the meantime, you have the option to manually record deposits in QuickBooks Online.
For detailed information on setting up QuickBooks Payments, you can use this resource: Accept customer payments.
Additionally, you can run an Invoice and Received Payments report to check which invoices are already paid by your customers.
