The truck you buy for December stands still in February
By navichain team

Every small carrier meets the same question sooner or later, usually in the middle of a good month. There is more freight than there are vehicles, the customer is asking for a commitment, and the obvious answer is another truck. The obvious answer has a ten-year shadow: financing, insurance, a driver to find and then keep busy, workshop slots, statutory dates, and a fixed cost that does not care whether November’s volume repeats in February.
The other answer is to rent the capacity for as long as you need it: hand the run to another carrier, keep the customer, and give the vehicle back when the peak ends. Most fleets do this long before they formalise it — a phone call to someone you know, a rate agreed verbally, a job that mostly goes fine.
The reason to think about it properly is not that the phone call fails often. It is that when it fails, it fails in ways that cost more than the load.
What you hand over, and what you do not
You hand over the driving. You do not hand over the contract.
To your customer nothing has changed: they booked you, they will chase you, and they will dispute the invoice with you. That intuition is also the legal position on international road carriage. Under Article 3 of the CMR Convention, the carrier is responsible for the acts and omissions of its agents and servants, and of any other persons whose services it makes use of to perform the carriage, acting within the scope of their employment, as if those acts were its own. Subcontracting moves the truck. It does not move the liability.
There is a related distinction worth knowing, because the words get used interchangeably. Article 34 of the same convention covers successive carriage — one contract performed by several carriers in turn — where each becomes a party to the contract by taking over both the goods and the consignment note, and each is responsible for the whole carriage. Handing a load to a subcontractor who signs nothing and takes no consignment note is not that. It is you, performing your own contract, using someone else’s vehicle.
Either way, the paperwork between you and the other carrier is not a formality. It is the only record of what was agreed, and it is what your insurer will ask for.
The office work does not shrink — it changes shape
The seductive part of subcontracting is that the vehicle problem disappears immediately. What replaces it is a coordination problem, and those are easy to underestimate because no single piece of one is hard.
The booking now exists in two places: yours, with the customer’s terms, price and expectations, and theirs, with whatever they wrote down. Every difference between those two records is a dispute waiting for a slow week — the collection window that was “morning” to you and “before twelve” to them, the tail lift you assumed, the ADR class nobody mentioned, the pallet count that changed after the price was agreed.
Then the proof has to come back. A signed POD in a subcontractor’s cab, or in a photo on someone’s phone, is not proof you can send to your customer — and you cannot invoice cleanly without it. Chasing PODs from other carriers is one of the quiet time sinks of this work, and it gets worse exactly when you are busiest, which is the only time you subcontract at all.
And the rate has to be agreed before the truck moves, in writing, with what it includes. Waiting time, a second delivery attempt, ferry costs, tolls, a return leg implied but not stated: each becomes a negotiation after the fact, by which time you have invoiced your customer at a price you cannot change.
The visibility gap is the real difference
When your own driver is running late, you know before the customer does. The phone is in the cab, the vehicle is on your map, and the conversation you have with the receiver is a warning rather than an apology.
When a subcontractor is running late, you find out when the receiver rings you. That is the largest operational difference between owning capacity and renting it, and it is not solved by asking for a tracking link — many small carriers cannot give you one.
What you can realistically ask for is honesty at four moments: loaded, en route with an ETA, delivered, and — the one that matters most — something has gone wrong. That is a low bar, achievable over the phone, and worth writing into the arrangement rather than hoping for. A subcontractor who tells you about a problem at eleven is worth more than one who is slightly cheaper and tells you at four.
The corollary is a discipline about your own promises. Do not sell live tracking on a leg you have subcontracted to someone who will not give it to you. A customer shown a map that turns out to be stale has been told something false by your system, and they will remember that longer than the delay.
The customer should not have to care
The test of subcontracted work is that the customer’s experience is unchanged: same contact, same documents, same references, same invoice. Nobody should have to learn a second carrier’s name to find out where their goods are.
That is an information-architecture decision more than a service one. If the job lives in your system as your booking, with the subcontractor recorded as how it was performed, your reference travels the whole way. If the job effectively moves into the other carrier’s world, your customer starts receiving fragments of it — a different consignment number on the POD, a driver who does not know your company’s name, a delivery note raising a question you now have to answer second-hand.
The commercial half: margin you can actually see
Subcontracting is one of the few places in a small carrier’s business where margin is knowable per job rather than smeared across the month: what you charged minus what you paid, on that load, with no vehicle costs to allocate. That is the number that tells you whether a lane is worth doing at all.
It is also the number most easily lost. The subcontractor’s invoice arrives three weeks later, in a batch, referencing their job numbers rather than yours, with an extra line for waiting time. If nobody matches those lines back to the loads, margin per job degrades into the difference between two totals — exactly precise enough to look fine, and never precise enough to act on.
Choosing, and then keeping, the ones that work
Two documents before the first load: the operator’s licence, and a current goods-in-transit insurance certificate with the cover level on it. Record the expiry date and ask again when it passes. A subcontractor whose insurance lapsed in March is not a paperwork problem — it is your loss when something goes wrong in April.
After that, the useful thing is a short list rather than a spot market. Three carriers who know your customers, your documentation and your standards out-perform a fresh search every time, and they answer the phone in December, which is when it matters. That is built by paying on time and giving enough notice to plan.
And when to actually buy the truck
The honest signal is not a busy month. It is repeated, contracted volume on the same lanes, where subcontracting is costing you a consistent slice of margin for capacity you would fill yourself all year. Until that is visible in your own numbers, renting is the cheaper way of being wrong: if the volume evaporates you stop calling, whereas a vehicle you bought stays bought.
Where navichain fits
navichain treats a subcontracted job as your booking, performed by somebody else — carrier records with matching and cost estimation, so placing a load is a decision rather than a phone round, while the customer’s reference, documents and portal view stay yours throughout. Costs sit against the same booking as the revenue, so margin on a subcontracted load is a figure rather than an inference, and the supplier invoice is checked against the order before it is paid. All of it is on every plan — you pay for scale, not capabilities — from 995 kr a month, billed monthly with no lock-in. The platform page has the detail, solutions covers a forwarding operation, and pricing is public.
