At Sendcloud you will receive a bi-weekly invoice for the shipping labels that you have created. You can read more about how you're invoiced and how to set up your payment method here.
Sometimes it can be that a parcel that you have shipped returns to you. If a parcel cannot be delivered, was refused to the customer or had an additional delivery attempt, you may be charged for these extra costs incurred. Similarly, if a parcel which is still in transport receives a new instruction or change of address, the carrier may also charge an extra fee for this service because the shipment will receive extra handling, must be reprocessed and redelivered.
If any of the situations above occurs and the carrier charges an extra fee it will be clearly specified on your invoice.
You can view and download your invoices in the Sendcloud platform by navigating to Settings > Financial.
