Most operations do not know what their carrier bill actually was. They add up the label costs in a spreadsheet and take the sum, which is what the labels cost when they were bought rather than what the carrier charged. Carriers adjust the price after their facility has the parcel, and the difference never reaches the spreadsheet.
I have seen adjustments and fees run to nearly $50,000 across a year. That is a full-time salary leaving the business without anyone having decided to spend it.
The record exists. If you use ShipStation’s carrier accounts, the billing data sits two clicks away and shows each adjustment as its own line.
This route only works on ShipStation carrier accounts. On your own accounts the same records live in each carrier’s billing portal instead.
Adjustment ID opens the charge the carrier added after you paid for the label, and the reason they gave for it.What you are looking for is the pattern rather than the total. Adjustments cluster: one SKU whose dimensions are wrong, one lane picking up a surcharge nobody priced, one service being re-rated on every shipment. The total tells you it is worth fixing. The clustering tells you what to fix first.
Knowing how a carrier prices a parcel is useful. The harder question is which parcel to make — because the packing decision sets the dimensional weight and the cubic tier, and the cheapest box changes with the contents, the destination and the rate card.
There are eight situations where that decision has grown past what a rule can express. Most operations are in two or three of them.
