How does billing work from each carrier at EasyPost?
There are a few methods that a carrier will charge you for billing depending on the selected carrier.
The USPS operates on a prepaid postage billing method. With this model you will be charged for the postage when you create the label.
Carriers such as FedEx, UPS and DHL Express operate on a bill on scan model of billing. This means that you are not charged by the carrier until you hand the package over to them and it is scanned. Once this occurs the package has entered the mail stream and your account will be charged accordingly.
For carriers such as Royal Mail, Asendia and Canpar you will be billed upon manifesting a shipment. To manifest a Shipment you will need to create a scan form object for the shipments. You can read more about this at:
