Transport mode comparison
How We Match Shipments to Transport Modes
A recommendation is only useful if you can see the reasoning behind it. This page sets out the fixed order of criteria we apply before we suggest a mode, a route or a handling plan.
How the order works
The criteria run in sequence, and each one removes options
The order matters. A deadline can rule out groupage before price is ever discussed, and a temperature requirement can settle the vehicle choice before a route is drawn. We apply the checks below in this sequence so the shortlist at the end is one the goods can actually travel on — not the cheapest combination on paper.
If your own priorities differ, say so at the start. A shipper who tells us the deadline is soft but the loading window is tight gets a different answer, and a better one, than a shipper who only sends a lane and a pallet count.
First check
Delivery date
Second check
Volume and weight
Third check
Handling and fragility
Fourth check
Conditions, customs, cost
Constraint one
The delivery date comes first
Everything else is secondary to when the goods have to arrive. A shipment with a fixed appointment narrows the options immediately: groupage depends on a trailer filling on schedule, and multimodal depends on a sailing or a departure that may not align.
If the date is flexible, more routes open up and the cost usually falls. We ask for the deadline before we ask for anything else, because a plan built around price and then fitted to a deadline is how delays get designed in.
What helps us here: the appointment time if there is one, the opening hours at the receiving address, and whether the goods can be delivered early. Those three answers do more work than a rate request.
Deadline first
A fixed appointment time changes which modes are even worth quoting. Flexible dates usually cost less.
Constraint two
Volume, weight and how the cargo stacks
The second question is what is actually moving. Pallet count, total weight, and whether the goods can be stacked or need floor space determine which vehicle type is even possible.
Twelve stackable pallets and twelve non-stackable pallets occupy very different amounts of a trailer, and the difference changes the groupage calculation. Out-of-gauge dimensions push the shipment toward a low-bed or a project plan. This is arithmetic, not judgement, and it eliminates options quickly.
What we need: number of pallets, whether they stack, total weight, and the longest single item. Send those four numbers and the vehicle question mostly answers itself.
Stacks freely
Stackable pallets fit a groupage trailer without wasting height, so the space you pay for is close to the space you use.
Floor loaded
Non-stackable goods consume floor space and trailer height they never use, which usually shifts the answer toward a dedicated vehicle.
Out of gauge
Overheight or overwidth pieces need permits and a different trailer class, so they are planned separately from standard freight.
Constraint three
Handling requirements and fragility
How many times your goods can be touched is a real constraint. Groupage routes freight through a consolidation point, which means additional handling. LTL reduces that. A full trailer eliminates it.
Touches per journey
- Groupage — consolidation in, consolidation out Most handling
- LTL — fewer transfer points on the lane Fewer
- Full trailer — loaded once, delivered Fewest
For fragile, high-value or awkwardly shaped cargo, the extra cost of fewer touches is often worth paying, and we will say so even when the cheaper option exists. The reverse is also true: if your goods are robust and the schedule has slack, we will not upsell you a dedicated vehicle.
Constraint four
Temperature and special conditions
If the cargo needs a controlled temperature range, the mode choice is largely settled before cost enters the conversation. Refrigerated trailers are a specific asset, they need pre-cooling, and they cannot be substituted with a standard vehicle on the day.
Cold chain shipments also need delivery slots that allow quick unloading, which affects which routes are workable. We treat temperature as a hard constraint rather than a preference, because a drifted range is not a delay, it is a loss.
Tell us the temperature band, the maximum time the goods may sit on a dock, and whether the receiving site can accept a refrigerated trailer directly. Those answers decide whether a lane is realistic at all.
Constraint five
Customs status and documentation readiness
Whether the shipment crosses an EU border changes the plan. Within the EU, goods move freely and the transport can be booked on its own terms. Outside it, the customs work has to run in parallel with the transport, and the declaration should be prepared before the vehicle is dispatched.
We check the customs position early because it is the most common source of delays that no amount of good driving can fix. If the documentation is not ready, we would rather tell you now than at the terminal.
What we check before the vehicle is booked
- Status Goods moving within the EU or crossing a border, and which one
- Papers Commercial invoice, packing list and goods description prepared in advance
- Declarant Who files the declaration, and whether it runs in parallel with loading
- Timing How much slack sits between the customs release and the delivery appointment
Constraint six
Cost structure, not just the headline price
Comparing quotes on the total number alone hides where the money goes. Groupage prices scale with the space you occupy. FTL prices per vehicle, so the unit cost falls as you fill it. Multimodal adds transhipment costs that may or may not be offset on a long lane. Air freight is priced per kilo and is in a different category entirely.
We set out which cost structure applies so you can see whether your volume is on the right side of the crossover — the point where paying for a whole vehicle becomes cheaper than paying for part of one.
Priced by space
Groupage bills the lane metres or pallet positions you take, so the total rises with the load, not the truck.
Priced by vehicle
A full trailer is one price whether it runs half full or full, which is why unit cost falls as you load it.
Priced with transhipment
Multimodal adds a transfer cost at each handover, which longer lanes can absorb and short ones usually cannot.
Priced by weight
Air freight is billed per kilo and compared on its own, because the cost logic does not transfer to road or sea.
Constraint seven
Transit time and its reliability
Groupage
Predictable, not instant
Departures follow consolidation schedules, so the transit window is steady but it does not start the moment you book.
Full trailer
Predictable and immediate
A dedicated vehicle leaves when you need it and runs direct, which makes the arrival estimate the easiest to hold.
Multimodal
Predictable if the sailing holds
The schedule is firm when the sailing departs on time, and less so when weather or terminal congestion moves it.
A fast transit time that varies by two days is less useful than a slower one that holds. We will tell you the realistic range rather than the best case, because a plan that only works when everything goes right is not a plan.
A plan that only works when everything goes right is not a plan. We quote the range we expect to hold, not the number that wins the comparison.

Judgement call
When we recommend against the obvious choice
Sometimes the cheapest option is the wrong one and the fastest option is unnecessary. A shipment with a generous deadline and robust cargo does not need a dedicated trailer. A time-critical consignment does not belong in a groupage network however attractive the price looks.
Two common cases
Flexible deadline, robust goods. We will point you to groupage and explain which departure it rides, rather than quoting a trailer you do not need.
Fixed appointment, fragile goods. We will say plainly that the groupage saving is not worth the extra handling, even when the number looks better.
We will recommend against the option that does not fit, and explain which constraint rules it out. If you disagree with our reasoning, say so. It is your freight, and the criteria above are there to be argued with.
Questions shippers ask before they send details
What do you need from me to compare options?Open
The delivery date or appointment window, pallet count and whether the goods stack, total weight, the longest single item, and whether the shipment stays inside the EU. Temperature requirements and any fragility notes help too. With those details we can tell you which modes remain possible before we talk about price.
Can you compare a groupage quote against a full trailer?Open
Yes, and it is worth doing once your volume approaches half a trailer. Groupage scales with the space you take, while a full trailer is one price whether it runs half full or full. We will show you where the crossover sits on your lane so you can decide rather than guess.
Does a customs border always mean a slower plan?Open
Not necessarily, but it means the declaration has to be prepared in parallel with the transport instead of after it. If the papers are ready before the vehicle is dispatched, the customs work usually keeps pace with the drive. If they are not, the delay is rarely a driving problem.
What if I disagree with the recommendation?Open
Say so and tell us which constraint you would trade. If you accept a later arrival, groupage opens up again. If you accept a higher cost, a dedicated vehicle removes the handling risk. The reasoning is meant to be checked, not accepted on trust.
Do you handle warehousing alongside transport?Open
Yes. Storage, contract logistics and customs coordination can sit on the same plan as the transport leg, which is often how a route with a tight appointment becomes workable in the first place. The comparison then includes where the goods wait, not only how they move.
Where to go next
Check the criteria against the mode you had in mind
Most questions about our reasoning disappear once you see how a mode actually runs. The pages below cover the transport modes we work with, the warehouse side of a plan, and the customs work that runs alongside a cross-border lane.
