Help with Shipping Payment

[tarotbear]

Hi community, 

So I recently sent an invoice to a customer, and they claim that they've paid it, however when I check my paypal account, the amount seems to be unpaid. 

My customer claims that I need to "ship asap & send the shipment receipt to Paypal for their verifications so they can process and credit your account" but I haven't received any such details or notification emails from PayPal regarding this, and it's been over 6 hours since they claim to have sent payment. 

It's my first time making this sort of sale on PayPal. How do I proceed from this?

it is a scam.

Paypal could withhold your payment 3-21 days after tracking shows it has been delivered to his address.

but if you dont see the payment or receive an email from Paypal,you did not get paid.
