Does ShipStation have discounted rates for shipping?

Yes, ShipStation offers discounted shipping rates to its users. This is one of the key benefits of using a service like ShipStation for businesses, particularly small to medium-sized ones. 

These discounts are possible because of the volume of shipping that ShipStation handles, which allows them to negotiate lower rates with carriers.

Who Does ShipStation Offer Discounted Rates For?

ShipStation only offers discounted shipping rates from USPS, UPS, and DHL. If you want to ship with FedEx or regional carriers like GLS, you’ll have to set up accounts with those carriers directly.

How Can You Select the Cheapest Rate for Every Shipment?

If you want to have the cheapest shipping rate selected for every order in ShipStation, you can try automation rules.  Learn more about automation rules here. 

A limitation of automation rules is that they don’t check live rates for shipments.  If you want to have the cheapest rate for every shipment based on live rates you can try String.

String integrates directly with ShipStation to auto-select the cheapest shipping rate for every order. 

You can get a free savings analysis from String to find out how much you’ll save on shipping by requesting a demo at www.meetstring.com.

Stop Leaving Money on the Table — Let String Handle It

Understanding cubic pricing is one thing. Actuallycapturing those savings on every single shipment is another.

The pitfalls are real: wrong box dimensions, inaccurate weights, automation rules that misfire, and adjustments that quietly eat into your margins. Even platforms that claim to handle cubic pricing automatically can leave money on the table if your package data isn't dialed in.

That's exactly what String was built to solve. String automatically selects the right package size for each order and then compares cubic and standard rates side by side — so you always ship at the lowest possible cost, every time, without any manual guesswork.

No spreadsheets. No second-guessing. Just optimized rates on autopilot.

If you're shipping dense, small-to-mid-sized products and you're not 100% confident you're capturing cubic savings on every label, it's worth a conversation.
