Using PayPal and NetSuite

When the customer completes checkout, a sales order is created
in NetSuite with payment authorized by PayPal. The sales order
status in NetSuite is either pending fulfillment or pending
approval, depending on your accounting settings. When you bill
the order, payment is received from PayPal.

After an order is created, NetSuite initiates an authorization
request to PayPal for the full order amount. When the Web store
shopper approves the authorization, a three day honor period
begins. PayPal places a hold on the shopper’s payment
account for the amount of the order to ensure availability of
the funds for capture.

During the three day honor period, you are guaranteed to capture
the funds as long as the authorization is valid. Please contact
PayPal for more information about their validation process.
You have three days from the time the order is created to
fulfill the order and capture the funds. If you attempt to
capture the funds after the three day honor period, NetSuite
voids the original authorization, initiates a new authorization,
and attempts to capture the funds. By default your PayPal
account is restricted to a single authorization. NetSuite can
initiate only as many authorizations as your paypal account
allows within a 29 day period.
