Multi-Carrier Shipping Software
Multi-carrier shipping software is software that connects to several parcel carriers so a shipper can compare rates, buy labels, print documents, and track packages from one interface.
Why it matters for ecommerce brands
Multi-carrier shipping software lets you buy labels from several carriers in one place, so you can rate shop and avoid depending on one carrier's prices or service. Brands without a full WMS use it to import orders, apply shipping rules, and send tracking back to the store. For example, if rate shopping between two carriers saves $0.60 on 40% of 6,000 monthly shipments, that is $1,440 a month, which can easily exceed the software fee. Many 3PLs and WMS platforms include similar tools.
Common questions
- What does multi-carrier shipping software do?
- It imports orders, compares rates across connected carriers, buys and prints labels, and sends tracking numbers back to the sales channel. Some also apply automation rules for box selection and service choice.
- Can I use my own carrier accounts in shipping software?
- Most platforms let you connect your own negotiated UPS, FedEx, or USPS accounts, and many also offer their own discounted rates. Compare both, since your own contract may include discounts or volume commitments the platform rates do not.
- Do I need shipping software if I use a 3PL?
- Usually not, because the 3PL's WMS buys labels and handles carrier connections. You may still want visibility into the rates and services it chooses, so ask for shipment-level reports.
