Teapplix can bulk print both domestic and international UPS shipping labels, with packing lists if needed. Teapplix also can generate commercial invoices for international shipments, in bulk, with pre-filled information.
Teapplix provides rate quotes and address correction when you click on the "rate" link. To setup for that, click on "Setup => UPS". The shipping labels and rate quotes are obtained from your own UPS account.
UPS Online API
This is the default and recommend method. You get online rate quotes, and the shipping label come out of Teapplix in bulk as PDF. You can reprint, cancel directly in Teapplix. Online API supports 4x6 and 8x11 2 per page labels, and support all UPS shipping methods.
Note that, with UPS online API lables, you won't need to generate end of day reports/shipping manifest, the package tracking number is automatically uploaded to UPS website.
And due to UPS API limitations, with online API, you will not be able to request Delivery Intercept.
