FIVE PLACES TO LOOK
Negotiating courier rates is an obvious place to start when shipping costs rise. But the base rate is only part of the bill.
Packaging, surcharges, destination rules and billing discrepancies all affect what you ultimately pay. A competitive rate can still produce an expensive shipment if those details go unchecked.
The opportunity starts with visibility: understanding what changed, why it changed and whether the charge matches your agreement.
Here are five places to look.
01
A total shipping figure tells you how much you spent. It doesn’t explain why.
Fuel adjustments, peak-season charges and remote-area fees can move independently of your base rates. When they’re grouped into one number, it becomes harder to distinguish a rate increase from a change in your order mix—or a charge that needs checking.
Break your shipping spend into its main components and track them over time:
•
Base transport charges
•
Fuel surcharges
•
Peak or seasonal charges
•
Remote or extended-area fees
•
Other handling and service charges
Compare each charge against the terms that applied when the shipment was sent. Tracking both the amount and how often it appears helps you identify what is driving an increase.
THE USEFUL QUESTION
02
Two shipments travelling a similar distance can attract different charges.
Couriers define their own delivery zones and remote-area rules. A postcode that falls within one courier’s standard network may attract an additional fee with another.
Map remote-area charges to the destinations that trigger them, then check those postcodes against the applicable courier schedule.
Look for recurring patterns:
•
Which destinations attract the most additional fees?
•
Are the charges consistent with the agreed terms?
•
Could another service offer a lower total cost for those orders?
The answer may be a routing change for a specific group of destinations, rather than a courier change across your entire business.
THE USEFUL QUESTION
03
A lightweight product can still be expensive to ship if it travels in a large box.
Where dimensional—or volumetric—weight applies, the space a parcel occupies affects its billable weight. An oversized box can therefore push a shipment into a higher price bracket, even when the product itself weighs very little.
Start with your most common products and order combinations. Compare the product dimensions, packaging used and weight recorded on the invoice.
Look for:
•
Boxes with unnecessary empty space
•
A single box size used for very different products
•
Multi-item orders packed inefficiently
•
Packaging dimensions that repeatedly cross a billing threshold
Smaller packaging is only useful if it still protects the product. Assess shipping costs alongside packing time, material costs and damage rates.
THE USEFUL QUESTION
04
Average shipping cost is a useful headline measure. On its own, it can hide the orders that deserve attention.
A rising average might reflect heavier orders, a different destination mix or more customers choosing express delivery. It could also point to packaging changes or additional fees.
Break costs down by:
•
Product or SKU
•
Single-item versus multi-item orders
•
Destination and delivery zone
•
Courier and service level
•
Packaging type and fulfilment location
Then compare similar shipments over time. A recurring cost increase within one group gives you something specific to investigate. An overall average rarely tells you where to start.
THE USEFUL QUESTION
05
An invoice records what you were charged. Checking it against your agreed rates helps establish whether that charge is expected.
Bring together the order details, shipment information, applicable rate card and invoice. Review whether:
•
The correct service and rate were used
•
The billed weight matches the applicable calculation
•
Surcharges follow the agreed terms
•
Any charges appear more than once
A difference is a reason to investigate, not automatic proof of an error. Missing shipment details, minimum charges or contract terms may explain it. Keep the supporting evidence with each finding so you can raise a clear, specific query with your courier or 3PL.
THE USEFUL QUESTION
Better rates remain worth pursuing. But they are only one part of cost control.
Understanding your shipping bill gives you more precise options: change packaging, adjust routing, review a surcharge, correct a billing discrepancy or negotiate the charges that matter most to your business.
Start with one recent period. Identify the largest unexplained differences. Make a targeted change, then measure the result.
The aim is straightforward: know what you should be paying, understand what you actually paid, and close the gap where you can.
