ShipEngine StrawberryAutomate your shipping rate audit with an AI agent
Every parcel in the period matched to its carrier invoice line, so a 14 percent gap breaks down into the surcharges that caused it.
You quoted a rate, bought a label at that rate, and the carrier invoice arrived 14 percent higher. The gap is made of a dimensional weight recalculation, a residential surcharge, an address correction fee, a fuel adjustment, and one parcel measured differently at the depot.
A companion matches every shipment to its invoice line and tells you which surcharge accounts for how much. That is the number that lets you change the quote or argue with the carrier.
You connect ShipEngine once and see exactly what it can reach before you allow it. Buying a label spends money, so it waits for your confirmation.
Quoted against billed, parcel by parcel
A companion pulls every shipment for the period with the rate it was created at, works through the carrier invoice, and matches them up.
What comes back is the list of parcels where the two disagree and, for each, the surcharge or adjustment that explains it. Most teams know shipping costs more than they quoted. Very few can say which surcharge accounts for how much.
Which service is quietly the wrong choice?
Rate shopping picks the cheapest quote at the moment of purchase.
A carrier fifty cents cheaper that requires a redelivery on one parcel in twenty costs more.
A companion reads the transit and exception history per carrier and lane and reports the real cost, including the deliveries that failed. That is the finding that changes a routing rule.
- Cost compared including surcharges and failed-delivery consequences rather than on the quoted rate alone.
- Exceptions grouped by carrier and by lane, so the pattern is visible.
- Label purchase held behind confirmation, because it spends money.
Tracking that gets read
The API tells you a status.
The carrier’s own page frequently tells you more, including the free-text scan detail explaining why a parcel is sitting still.
A companion reads both for every shipment that matters and drafts the customer message for the ones that stopped moving. The recurring version is track shipment and order status.
What should stay in code?
The dispatch path.
Service selection, label creation, manifesting and the retry logic around a carrier outage run at volume and belong in tested code.
The analysis and the exceptions are where the money quietly leaks, and that is the pass a companion runs. Scheduled monthly, the rate audit fits alongside your other operations routines.
