Why does paid Invoice show as ‘Pending’?

The reason for the ‘Pending’ is that payment method was ‘PayPal eCheck’, which PayPal takes 3 to 5 business days for the payment to clear. We mark such invoices in your Servicejoy account as “Pending” which indicates we’re waiting for a response from PayPal.
Q: Does this mean that potentially I could ship something and the “eCheck” not clear?A: We recommend to wait for the payment to clear before shipping physical items.
