Welcome back to my blog series on optimizing shipping costs!
For those who don’t know me, I’m Tyler, and I founded String to help eCommerce businesses save time and money on order fulfillment. Over the last few months, I’ve spoken with numerous eCommerce logistics leaders who don’t know what their actual carrier bill is at the end of the month. They’re adding up the shipping label costs in a spreadsheet and taking the sum of those figures. But there’s a critical problem with this approach! It doesn’t tell you how much you ACTUALLY paid. This is because carriers are able to charge you adjustments and fees after their facilities receive a package of yours.
In some cases, I’ve seen annual adjustments and fees add up to nearly $50,000!!! That’s $50,000 the business had no idea they were spending… Let that sink in. A full time employee salary disappearing without you even knowing it.
If you’re like me, you want to know how much you’re actually paying and gain some insight into why you’re being charged fees and adjustments. If you use ShipStation, you’re in luck! Because today I’m going to show you how to view your actual billing data and know why you’re being charged more than you think you are. So buckle up and open up ShipStation folks, because we’re about to get our hands dirty.
DISCLAIMER: This only works if you use ShipStation carrier accounts. If you have your own carrier accounts, you’ll need to log into their billing portals.
Now you evaluate both why you’re receiving adjustments and how much they’re costing you.
I really hope this helps and if you have any questions don’t hesitate to reach out and ask me for help. Thank you so much and have a great week!
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.
