Last-mile cost
The weight, the dimensions and the contents that make a label accurate are set when the order goes to the factory, and a border changes everything the label relies on.
Last-mile cost is usually blamed on the carrier, and the carrier blames the label. Most of the cost and most of the failures are created upstream, weeks before a parcel reaches a van, and the label is the last place where that earlier mistake turns into a surcharge.
Label data
A label is a promise to the carrier: this box, this weight, these dimensions, this content, to this address. When any of those is a guess, the carrier corrects it at the depot and charges for the correction. A parcel re-rated because the box was two centimetres bigger than the label said is a familiar line on a disputed invoice. The packer who printed the label had to estimate, because nobody recorded the item's dimensions when the order left for the factory.
So the data is set where it is first known. The item's identity is allocated against the purchase order, with the weight, the dimensions and the contents per item, and that data rides with the unit through freight, receipt and picking to the moment the label is printed. The label is printed from that record, so nobody on the bench has to estimate.
By the time a parcel is on a bench, the surcharge has usually already been earned.
Borders
In Europe, the hard part of the last mile is the border. Addressing standards, postal codes, parcel-shop networks and customs all change at the border. A label that is correct for a French address can fail in Germany on address format alone, and each failure is a failed delivery or a return to sender. Your account normalises those differences so that your brand does not have to learn each country's habits, and the identity that travelled from the purchase order gives the label the contents, while the destination comes with the customer's order.
Returns
A return that arrives as an unidentified box has to be opened, matched to an order and inspected before anyone can identify it and decide its next step. A return that scans against the identity on the outbound label is identified at the door. The difference is the same as at the label: whether the data about the item exists before the item moves. Returns shows that check at the door.
Carrier choice
With the data right, the rule that picks the carrier has something to work with. The rate is selected at label time under a rule you set, on the cost of the moment and on observed performance, and you can see which rate won and why. On our rates in France and the United Kingdom that choice is made at the exact carrier price with zero markup; on your own contracts, at your rate. If the weight it is given is wrong, the rule still picks the best rate for that wrong weight, and the depot correction follows whichever carrier won.
Questions we get asked.
We have good weights in our ERP. Isn't that enough?
It helps, but an ERP usually knows the product and not the unit, and it stops at the purchase order. The surcharge is earned per unit, at the depot, against the dimensions of the actual box. The identity carries the unit's data to the label; the ERP is one of the places it comes from.
Which surcharges does this prevent?
The ones caused by a declaration that did not match the parcel: dimensional-weight re-rates and corrections for a wrong weight or wrong contents. Surcharges that are in the carrier's contract, a remote-area fee for instance, still apply, and those are the ones the invoice audit checks against your contract.
Does this require changing how we buy from suppliers?
No. The identity is allocated against the purchase order you already raise, and the data it needs is the data a good purchase order already carries. The difference is that it stays attached to the unit instead of being retyped at every step.
Where does the saving show up?
On the carrier invoice, as lines that are no longer there, and in the delivery rate, as parcels that reach the right address first time. Both are visible in your account, line by line.
