How do you build a landed-cost comparison?
By pricing everything the quote does not mention. Unit price is a fraction of the answer: add minimum order quantities, delivery charges, payment terms, quote validity, and — on imports — freight, insurance, customs duty, conformity certification and the currency you will actually settle in. Then, and only then, compare.
What the cheapest quote usually leaves out
A minimum order quantity that forces you to buy 40% more than you need. A delivery charge that is not in the rate. Payment terms of seven days against a competitor’s sixty, which is a financing cost even if nobody calls it one. A validity window of five days, in a market where your approval chain takes ten.
And on an import: freight, marine insurance, duty, clearance, conformity certification, the road leg from the port, and the exchange rate you will actually settle at rather than the one on the day of the quote.
The deviation that costs the most is the one you accept
The single most expensive line in any comparison is a quote that is cheap because it does not comply. It wins the award, it arrives on site, it fails the material inspection, and it is re-procured at spot prices with the programme now against you.
So specification compliance is not a footnote in the comparison. It is a gate before it. Flag the deviation before the purchase order, and route it for substitution approval — because a deviation approved deliberately is a saving, and a deviation discovered at inspection is a disaster with the same paperwork.
And the comparison itself is worth money
Competitive quoting produces hard savings of around 3–5% on procurement research, and considerably more where spend was previously fragmented across sites and nobody was aggregating it.
That is not a negotiation win. It is a process win — which is the only kind that survives the buyer leaving.
