One account, many carriers
No single carrier is the cheapest or fastest for every parcel. A light package across town, a heavy box across the country and an international order can each be best served by a different carrier and service.
SellTrac connects to a multi-carrier shipping network with access to more than 100 carriers, including USPS, UPS and FedEx. Instead of keeping separate accounts and websites, you see the available rates side by side for each shipment and choose per order.
How multi-carrier shipping works
Choosing the best carrier becomes part of creating the label.
-
Create the shipment
Start from a paid invoice, a batch of invoices, or a single label. Enter the package weight and dimensions.
-
Compare rates
SellTrac asks the carrier network for live rates and shows the available services and prices for that package.
-
Choose per order
Pick the cheapest option for one order and the fastest for another; you are not locked into one carrier.
-
Ship internationally with customs details
For cross-border parcels, fill in the customs declaration, including item descriptions and tariff numbers, as part of creating the label.
