A tender portal returns a list of acronyms. IFB, RFP, RFQ, RFI — and the temptation is to treat them as filing labels, a bureaucratic prefix in front of the thing you actually care about.
They are not labels. Each one describes how the award will be made, and therefore what a strong response contains. Answering an RFP as though it were an IFB is one of the more expensive mistakes available in public procurement, and it is made most often by firms that price well.
IFB: the lowest compliant price wins
An Invitation for Bid is used where the buyer already knows what it wants. The specification is closed, the scope is defined, and there is nothing to propose — only a price to put against a described piece of work.
Award goes to the lowest responsive and responsible bidder, and those two words carry the weight. Responsive means the bid met every mandatory requirement. Responsible means the firm is judged capable of performing. A bid can be the lowest number in the room and fail on either.
There is very little room for creativity, which is a useful thing to know before spending any on it. On an IFB, effort belongs in compliance and in the sharpness of the price, not in narrative.
RFP: the award is scored
A Request for Proposal is used where the buyer has a problem rather than a shopping list. It describes needs, constraints and objectives, and asks firms to propose an approach.
The response is evaluated against a published grid — methodology, team, schedule, relevant experience, and price. Price is one criterion among several, and frequently not the heaviest. That is what makes a higher-priced bid winnable, and it is also what makes a cheap one lose.
The practical consequence is that an RFP response is a document that has to earn points from an evaluator working through a rubric. Evidence scores. Adjectives do not.
RFQ: a price on something already defined
A Request for Quote is the simplest of the three. The buyer knows exactly what it needs, the requirement is common or low in value, and the question is what it costs.
Award usually goes to the lowest-priced technically acceptable quote, on a compressed timeline and with a fraction of the submission effort of an RFP.
For a firm that has never contracted with a particular public buyer, this is often the cheapest route to a first contract and a performance record with them.
RFI: not a tender at all
The acronym lists always include RFI and rarely explain it. A Request for Information gathers market intelligence before a procurement exists. There is no award and no contract at the end of it.
Firms skip RFIs for exactly that reason, which is backwards. Responding costs little and buys two things that are difficult to buy later: visibility with the buyer before the requirement is written, and occasionally some influence over what the eventual specification asks for. By the time the tender is published, both are gone.
The names are not standardized
The same word means different things in different jurisdictions, which matters for any firm bidding on both sides of the border.
Canadian buyers commonly use Invitation to Tender for what a United States agency calls an IFB, and federal procurement adds its own instruments for standing offers and supply arrangements. In Quebec, SEAO publishes the notice as an appel d'offres public regardless of which of these structures sits underneath it.
More importantly, the label on the cover page is not binding. Buyers issue documents titled RFP that are awarded on lowest compliant price, and documents titled RFQ that carry an evaluation grid. The acronym is a convention; the instructions to bidders are the contract.
Read the award mechanism, not the cover page.
Why misreading it is expensive
There are two failure modes and they cost differently.
Treating an RFP as an IFB produces a sharp price attached to a thin narrative. The firm loses on scored criteria it never addressed, and the worst version of this outcome is winning the price and losing the award — the estimating hours were spent, correctly, on the wrong half of the submission.
Treating an IFB as an RFP produces the opposite waste: weeks spent on approach and qualifications that no one is scoring, on a tender that was only ever going to be decided on a number.
What it changes in practice
Establish the award mechanism before the takeoff starts, because it determines where the hours go.
On an IFB or an RFQ, the principal risk is disqualification. The work is a complete compliance checklist and the most defensible price the firm can stand behind.
On an RFP, the principal risk is scoring poorly. The work is evidence mapped against the published criteria, and the bid/no-bid arithmetic changes, because a higher price can still win.
Determining which of these you are looking at is usually possible in the first few minutes of reading — the difficulty is that the answer is in the instructions to bidders rather than on the cover, and the cover is what the portal shows you. That is part of what Offra does on ingestion: identifying what each document in a tender set actually is, and pulling the award mechanism and evaluation criteria out with a reference back to the page they came from, so the question of what kind of competition this is gets answered before the estimating hours are committed rather than after.
