I have chooses “Let the customer pay” when inputting an invoice but it is given me an error message telling me to choose payment method?

Hi there, Sandra. I'm glad to share information about having your customer pay you electronically in QuickBooks Online (QBO).

Before we can turn on the option for our customers to electronically pay an invoice online, you'll have to set up a QuickBooks Payments account first. Please be reminded that QuickBooks Payment has a service charge per transaction. 

To activate a Payments account, select Activate Payments under the Customer payment options on your Invoice page. Then, follow the onscreen instructions for account registration.

On the other hand, you can also visit and register an account directly from the QuickBooks Payments website: QuickBooks Payments subscription. This link also contains information about this feature.

Once you have set up a QuickBooks Payments account, you can provide your customers with the option to pay the amount when you send them the invoice. Upon receiving the e-invoice, customers can easily make a payment that will be deposited into your account.

Moreover, you can also set up your customer's payment options by entering their account credentials. Example: PayPal or Visa (credit card), or accept via bank transfer. Kindly click the Edit beside Customer payment options. Then, fill in the necessary info needed.

For more information, refer to this article: Let your customers pay their way.
