The labels you create in Circle.us are prepaid, so you need to add some credits to your Circle.us account first. When your packages are delivered, Carriers ( UPS／FedEx) will send us the invoice. Some adjustments may be made based on the invoices, for instance, residential surcharge, additional handling surcharge or address correction surcharge may apply. But if you enter exact dimensions and weight of your package, there will be little or even no adjustment.
Step1. To add credits, please go to Finance < Transactions <Add Credit.
Step2. Choose the Payment method and Amount and click “Next”.
