Most stores never see what a shipment truly costs. This pulls real per-parcel charges straight from carrier invoices, matches each one to its order, and shows estimated-vs-actual shipping margin.
Carriers bill in dense weekly invoices, and the cost of any single shipment is buried in them — so most stores ship on a flat estimate and never learn the truth. This surfaces it.
It parses the piece-level detail from carrier invoices, matches each waybill back to its order, and compares what you charged against what you actually paid — turning shipping from a guess into a line you control.
I build reporting software that answers the question you actually have — owned outright, fed by your own data. Tell me what you're trying to see.
