Key takeaways
  • A freight tender, often run as a freight RFQ, is the process of inviting carriers to bid on defined lanes, equipment and volumes for a set period; the result is a set of contract rates with a validity date.
  • Invoiced cost drifts from tendered rates for process reasons: shipments outside the tendered lanes or equipment, spot bookings, surcharges billed on top of rates quoted as all-in, expired validity, volume below commitment and forwarders billing at their own rates.
  • Compliance is measured per invoice line: is there a tendered rate for the lane, equipment and date, does the billed rate match it, and what share of spend moved on tender versus spot.

Many freight teams run a tender every one or two years, award the lanes, load the rates into the rate card and treat the result as the cost of transport for the period. That is the right way to buy freight: it fixes a price for defined volumes and gives finance a number to plan on. What the award does not fix is what the carriers bill, and twelve months of invoices usually tell a different story from the award sheet. The examples below use ocean freight, where tendered and spot rate structures are most visible, but the same invoice-versus-award logic applies to air, road and parcel.

What does a freight RFQ actually fix?

A freight tender is the process of inviting carriers to bid on defined lanes, equipment types and expected volumes for a set period, with the result being contract rates valid for that period. In German procurement it is the Frachtausschreibung; transportation procurement teams usually just say "the RFQ".

An awarded rate is defined by four things: the lane at the level the tender specified (port pair, postcode pair or region), the equipment or service, the validity window, and the rate structure. A base rate leaves surcharges to be billed on top, usually by reference to a tariff or published table; an all-in rate is quoted as covering base freight plus a named set of surcharges. Xeneta's methodology, for example, defines its own ocean rates as a total port-to-port cost that includes BAF, CAF, canal and other relevant surcharges. Some awards add a minimum quantity commitment, with the contract saying what happens below it. Everything outside those dimensions, and everything the contract is silent on, is where the drift starts.

Tender rate vs invoiced rate: where does the gap come from?

The gap opens because the tender defines a subset of what gets shipped and billed, and the invoices cover all of it. A year later, the difference usually traces to one of six causes.

  1. Shipments outside the tendered lanes or equipment. A new plant, a re-routed flow or a 20-foot box on a lane tendered for 40-foot only: with no awarded rate to bill against, the carrier usually bills at tariff or at a quote.
  2. Spot bookings when capacity was short. When the contracted carrier cannot take the booking, or the shipment falls outside the contracted allocation, it may move at a spot price with another carrier. The Freightos Baltic Index describes the market it tracks as rolling short-term FAK spot tariffs and related surcharges: a different rate basis from a long-term awarded contract.
  3. Surcharges billed on top of rates tendered as all-in. A peak season surcharge or an emergency fuel line appears on an invoice whose base rate was meant to include it. Whether that line is payable depends on the contract terms, any tariff incorporated into it and the governing law; the line is grounds to check the all-in definition, not proof of an error.
  4. Rate validity expiring before the next tender. Awards often run late, and what applies in the gap depends on the contract: some roll over, some revert to the carrier's tariff, some are silent.
  5. Volume below the commitment. A contract can tie the rate to reaching the committed volume. Below it, the carrier may be entitled to a different rate, or the contract may say nothing.
  6. Forwarders re-billing at their own rates. A forwarder that books on the shipper's contract but invoices on its own terms produces lines that differ from the award. That is evidence of a mismatch between two documents, not proof of an overcharge, because the forwarder's own agreement may govern.

A seventh category sits entirely outside the tendered rate structure: charges for which no rate was ever agreed. In the invoices audited on our platform from January to September 2026, about one invoice line in eleven was a surcharge with no contracted rate, under more than 1,400 descriptions.

A tender fixes what you agreed to pay; only the invoices show what you paid.

A description billed once is hard to anticipate in a tender; it is caught on the invoice.

How do you measure contract rate compliance from the invoices?

Compliance is measured one invoice line at a time, by asking two questions: is there a tendered rate for this lane, equipment and date, and does the billed rate match it?

  1. Find the reference. Look up the awarded rate for the lane and equipment that was valid on the date the contract names. Contracts differ on which date decides the rate: booking, gate-in, sailing or delivery. If yours is silent, note it for the next tender.
  2. Compare base and surcharges separately. A matching base with an extra surcharge is a different finding from a base billed at the wrong level.
  3. Classify the line as matching, or as one of the categories below.
  4. Aggregate. Report the share of spend on tender versus spot, the count and value of lines with no rate reference, and the median gap per lane between billed and awarded rate. Median, not mean, so one mis-keyed invoice does not move the lane.
Line categoryWhat it usually suggestsWhat to check it against
On tender, base deviatesA rate table version or date rule differenceValidity dates and the date clause in the contract
On tender, extra surchargeA surcharge outside the all-in definition, or a base-plus structureThe all-in clause and any tariff it incorporates
No valid tendered rate, contract carrierOut-of-scope lane or equipment, expired validity, or a rate not loadedThe lane list and validity window in the award
No tendered rate, other carrierA spot booking or an approved carrier substitutionThe booking record and who approved the carrier change
No rate reference at allA charge nobody agreed a rate forWhether a tariff applies, and whether it belongs in the next tender

These are typical readings, not rules; the contract decides what follows from any of them.

Why does the gap go unnoticed for a year?

The gap goes unnoticed because the tender and the invoices are owned by different people on different cycles. Procurement typically closes the award and moves on; accounts payable often checks that the invoice matches a shipment, not that the rate matches the award; the next tender starts from last year's lanes rather than last year's invoices. Two process gaps do most of the damage: rate card versions in the payment system are not always maintained, so an expired rate can keep matching, and spot bookings may be approved in operations without being tagged as spot, so they can merge into the same spend line as contract moves.

What should change in the next freight tender?

The compliance read is worth doing only if it changes the next award. It usually points to four things.

  1. Clause wording. Name the date that decides which rate applies, what happens when validity expires before the next award, and what happens below the volume commitment.
Step 1 of 4

Freight sourcing that starts from the invoice data rather than the last award sheet tenders the lanes that moved, at the equipment that shipped, with the charges that appeared. That is freight rate management in practice.

Our RFQ module closes this loop: it compares bids on the real all-in cost per shipment rather than on base freight, and puts what carriers charged before next to what they are bidding now, so the next award is written against the invoices. To see how your last tender held up, we offer a free analysis on 100 shipments.

FAQ

What is the difference between a freight tender and a spot rate?

A freight tender usually produces contract rates agreed in advance for defined lanes, equipment and volumes over a validity period. A spot rate is quoted for a specific shipment or booking at the time of shipping, with its validity set by the quote.

Is a surcharge billed on top of an all-in tendered rate an overcharge?

Not automatically: whether the surcharge is payable depends on the contract terms, any tariff incorporated into it and the governing law. The invoice line is grounds to check the all-in definition in your contract and, where the surcharge falls inside it, grounds for a claim.

How often should tendered rates be checked against invoices?

Checking every invoice run, rather than once before the next tender, lets a team correct a lane or a clause while the contract is still live. A year-end review still has value, because it produces the list of changes for the next award.
