My customer can not find the pay now but on the app it’s not visible

Hi @joseph-greenfixp,

Thank you for dropping by here in the Community. I can help you fix the issue with the Pay Now button in QuickBooks Online.

Pay Now only reflect on your customer's end if you've already linked your QuickBooks Payments to QuickBooks Online. You can perform some troubleshooting steps to isolate and figure out the cause of the issue.

You can start by verifying if your Payments account is still connected. This way, we'll be able to determine if the problem is related to the connection with the add-on feature.

Here's how:

1. Sign in to QuickBooks Online as an admin.
2. Go to Settings ⚙ and then Account and settings.
3. Select the Products and services tab.
4. In the Existing account section, select Connect or Link Merchant Service.
5. In the window, select the QuickBooks Payment account you want to connect. Then select Connect.
6. Review the account info and make sure it's accurate. If everything looks good, select Connect.
7. When the connection is finished, sign out and sign back into QuickBooks Online.

If your Payment account is connected, I recommend you proceed by reviewing the invoice. Check the payment options to ensure you've added the necessary payment methods for the customer.

Please follow these steps:

1. Open the invoice.
2. Review the details.
3. Turn the switches on or off for ACH or Credit Card below Online payments.
4. Select Save.

If the necessary options are already selected, I recommend sending the invoice again. Your customer should be able to find the option below the payment methods (see screenshot below).
