A fixed freight rate is not a fixed shipment cost.
The rate on the contract is one line. The invoice that arrives weeks later carries fuel, surcharges, handling, storage and whatever it took to recover a shipment that missed its connection. Procurement negotiated the first number. Operations and finance live with the second.
Most of the gap between the two is decided before you sign. It sits in clauses that rarely get read the way an operator would read them.
Air Cargo News reported on 2 October 2026 that Xeneta's analysis of new airfreight contracts valid from the third quarter of 2026 found 60% were for three months or less, compared with 25% in the third quarter of 2025. Among those new contracts, the share of 12-month deals fell from 40% to 25%. Xeneta's chief airfreight officer, Niall van de Wouw, said shippers are looking for "floating mechanisms" with a base rate adjusted to what is happening in the market.
On ocean, C.H. Robinson's October 2026 ocean update makes a related point. Scheduled vessel capacity is not necessarily usable. Port congestion, and the steps carriers take to get schedules back on track, can change where and when that capacity is actually available. It also notes that a confirmed booking offers limited protection if the container cannot be positioned, accepted or connected to the intended sailing.
Those are reported findings. They are not a case for everyone moving to short-term contracts. The length of a contract matters less than whether you understand what can move inside it.
Start with what the rate includes. List every charge that is in, and every charge that is out: origin and destination handling, security, documentation, peak surcharges. If a charge is not named, plan for it to appear on the invoice.
Then read the fuel clause properly. You need to know:
A fuel clause that only ever moves upwards behaves like a surcharge. One tied to a benchmark nobody on your side can check is hard to hold anyone to. No single benchmark suits every mode or market, so test the one proposed against the lanes you actually ship.
An agreed rate, a capacity allocation and a confirmed booking are three different things. Agreements often blur them.
The rate tells you what you pay if space is provided. An allocation tells you how much space the provider intends to hold for you. A confirmed booking is a specific shipment on a specific departure. Ask what sits behind each one: booking lead times, cut-offs, routing assumptions, how rollovers are handled, and which exceptions release the provider from the commitment.
A contract does not guarantee service unless its terms say so. If service levels matter, they need to be written down with a consequence attached. Review those terms with your legal or contract adviser.
Shipments miss connections. What matters is what happens next, and who decides.
Agree in advance who proposes alternatives, who approves extra spend (and up to what amount), who pays for the recovery, and at what point the issue escalates. If this is assumed rather than agreed, the decision gets made under time pressure by whoever is available. Finance then meets it on the invoice.
The rate is one part of what a shipment costs. Several charges can sit outside it, and they are not interchangeable:
Free time, definitions and who bills each charge vary by carrier, terminal and market. Check what applies on each lane.
None of this means the cheapest quote is wrong. It can be the right choice when you understand the assumptions behind it and the risks you are carrying. The problem is choosing it without knowing either.
Put procurement, operations and finance in a room with the draft agreement. Work through three scenarios using the same document:
For each one, record who acts, who approves and who pays. Where the agreement gives no answer, you have found a clause to negotiate. Where the three teams give different answers, you have found a process to fix.
Optivis is operator-led. We work inside your operation with procurement, operations and finance to review agreements like this, then help put the changes in place. If you want an operator's view before you sign, start a conversation.
Most SEA expansions fail in the brief, not the warehouse. If you can't describe each market as its own operation, you're not ready to buy coverage.

Most brands treat returns as a customer-service problem. It isn't. It's a reverse operation nobody defined, then blamed on the 3PL, the portal, or the warehouse.
