Generally, an error would indicate that a payment had failed to complete.
The exact details as to why a payment failed would be something that would be shared by PayPal, upon the PayPal Account Owner reaching out to them directly.
Typical reasons for a payment to fail through PayPal would be:
- A lack of funds
- The Billing Agreement attempted, is no longer active
What to do if a payment fails
Generally, attempting a different payment method would be the best way to proceed if the invoice needs to be made immediately.
Keep in mind that an order and its invoice would not be canceled if a payment fails and would still be able to be paid through the Client Area by going to the “Invoices” page.
