Carriers do not tell you when they miss a guaranteed delivery. The refund exists, but finding the late shipments and claiming it is your job.
Expedited services cost several times what ground costs, and the premium buys a contractual delivery commitment rather than just a faster truck.
Where the service carries a guarantee and the carrier misses it, you are entitled to a refund. The terms differ by carrier and by service, and carriers change them, so read your own service guide rather than taking the entitlement from here.
At any real volume of expedited shipping, the refunds you never claimed are a meaningful number.
The work is the audit. Here is the process, in three steps.
The screens below are ShipStation. On another platform the steps are the same and the buttons are elsewhere.
Export one service level at a time. A file that mixes two-day and overnight shipments cannot be audited against a single guarantee, and a carrier will reject a claim built from one.
That gives you the data.
The audit is a spreadsheet formula comparing the ship date to the delivery date.
The examples below are Excel. Another spreadsheet will want slightly different syntax for the same comparison.
Every claim needs the tracking number, the guaranteed delivery time and the actual delivery time. UPS is the example below; the other carriers have equivalent forms.
If a carrier disputes a claim you think is valid, the delivery scan data in the export is usually what settles it.
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.
