Spot buying or contracted rates: how to cover a freight requirement
Freight can be bought each time it is needed or agreed in advance for a period. Each looks better than the other in a different market, which is why businesses tend to change approach immediately after being punished by the one they were using. A durable answer treats it as an allocation question rather than a preference.
Comparison criteria
Criteria are stated explicitly and neither option is declared a winner: which one fits depends on the constraint that binds hardest in your operation.
| Criterion | Spot buying | Contracted rates |
|---|---|---|
| Price behaviour | Follows the market in both directions, which is welcome when capacity is loose and painful when it is not. | Fixed for the agreed period, which protects against rises and forgoes the benefit of falls. |
| Access to capacity when demand surges | You compete with everyone else at the moment space is scarcest. | An agreement gives standing, though it is only as good as the operator's willingness to honour it under pressure. |
| Budgeting | Difficult, since the cost of next quarter's freight is unknown. | Straightforward, which matters where prices to customers were set in advance. |
| Administrative effort | Every movement requires sourcing, comparing and booking. | Concentrated into a tender and then largely automatic for the term. |
| Commitment | None beyond the shipment in hand. | Volume undertakings that can bind you if demand falls short, and relationship damage if they are missed. |
| Relationship with operators | Transactional, which limits the goodwill available when you need a favour. | Continuous, which is what produces cooperation during a disruption. |
| Suitability by lane | Fits irregular, one-off or seasonal movements that no operator could plan around. | Fits dense, repeating lanes where an operator can build a service around the volume. |
Choose Spot buying when
- Volumes are irregular or the lane will not repeat, so no operator can plan around it
- The market is clearly loose and agreements struck now would sit above the going rate
- You are testing a new lane and do not yet know what volume it will carry
- The requirement is urgent and outside whatever your agreements cover
Choose Contracted rates when
- Lanes repeat predictably and volume is worth committing to an operator
- Selling prices were fixed in advance and transport cost volatility would eat the margin
- Capacity access during peaks matters more than the last increment of rate
- Procurement capacity is limited and repeated sourcing is consuming the team
Allocate rather than choose
Mature freight buyers cover a proportion of predictable volume under agreement and leave a deliberate share exposed to the market. The committed portion secures capacity and stabilises the budget; the exposed portion keeps a live view of market pricing and preserves flexibility when volume disappoints. Deciding the proportion is the actual work. It follows from how confident you are in the forecast, how tolerant the business is of cost variation, and how badly a capacity failure would hurt. Review it as those change instead of after a market has already moved.
An agreement is a relationship, not a guarantee of space
Agreed rates hold while both parties find the arrangement tolerable. When markets tighten sharply, some operators prioritise shippers who supported them when capacity was loose. When markets loosen, some shippers walk away from agreements they signed. Both behaviours are remembered, and they determine what happens the next time conditions turn. Treat commitments as reciprocal, tender less often than you could, and be honest about the volume you will actually offer. Shippers with that reputation are the ones who get covered when space is short.
Tender design shapes what you receive
How a tender is run determines the quality of what comes back. Vague volumes, unrealistic service requirements and a lane list nobody can plan around produce cautious pricing and quiet non-performance later. Give operators the information they need to price properly: honest volumes, the seasonal shape, the delivery requirements that matter and the ones that do not. Include the terms that will govern acceptance, waiting time and failure, since those decide whether the rate holds in practice. A well-specified requirement usually returns better prices than a broad one, because the operator can size the commitment against something real.
Frequently asked questions
- How long should a freight agreement run?
- Long enough to be worth the tendering effort and short enough that a market shift does not lock in a bad position for years. Many buyers pair a longer term with a review mechanism tied to a published index or a defined trigger.
- What happens when a contracted operator declines a booking?
- It signals that the commitment has stopped working for them, and the useful response is a conversation rather than an immediate escalation. Understand whether the issue is the rate, the volume you actually provided, or conditions at your sites, since each has a different remedy.
- Should agreed rates be benchmarked during the term?
- Yes, quietly and continuously, using the share of volume you deliberately leave exposed. That gives evidence for the next negotiation without treating suppliers as a free quotation service.
Data limitations
- Logistics figures are operator-supplied inputs, not market data. GeoBusinessIQ holds no freight rates, transit times, capacity, or throughput data and does not estimate them — every result reflects only the figures you enter.
