What do the pending transactions mean?

We are using the PayPal tool on our form and there is a tab for "Incomplete Payments". When a transaction is incomplete does it mean that the customer has paid and PayPal is still processing the transaction? When I manually complete the incomplete payments, what does that mean? 

Hi,

The incomplete payments could also be an abandoned/cancelled payment submission. Mostly, the users must have not proceeded to complete the payment process when in Paypal sceen.

I suggest review this user guides to understand more.
