Responding to an Ambiguous RFP: Why Authenticity Wins When the Brief Is Blank
At some point in any supplier's career, an RFP arrives that is less a document and more a collective shrug. The requirements are vague, the success criteria are absent, and the scoring methodology (if one exists) was clearly written by someone who has never actually commissioned the service they are procuring. Responding to an ambiguous RFP is one of the more peculiar challenges in B2B sales: you are being asked to demonstrate expertise in answer to a question that has not really been asked.
Most suppliers respond to this situation the same way: play it safe, cover all the bases, and fill the document with language nobody can disagree with. The result is a proposal nobody remembers, and one that wins nothing. An authentic RFP response takes the opposite approach, and this article explains why it is the only one worth writing.
Why So Many RFPs Are Vague
Before addressing the response, it is worth understanding why ambiguous RFPs exist in such quantity. The answer is less mysterious than it appears.
Most procurement teams write RFPs without input from the people who will actually use the service. In corporate relocation, this means the brief is often authored by a procurement or finance function trying to apply a category framework to a service that does not fit neatly into one. They measure what they can measure: cost per move, average lead time, platform integration. They leave unasked the questions that actually determine whether a move succeeds. How do you handle an employee settling in without local support? What happens when a school placement falls through the week before arrival?
The result is a document that is technically complete and practically incomplete. An ambiguous RFP is not a failure of the procurement team. It is usually a gap between their framework and the real complexity of what they are buying. The supplier who spots that gap and names it clearly is the one that stands out.
The Generic Trap: What Most Suppliers Do Wrong
When a brief is unclear, the most common response is to become everything to everyone. The proposal covers every possible requirement. The language is inclusive. The positioning is deliberately inoffensive. Nothing is claimed that could be questioned, and nothing is offered that could be remembered.
This is the Generic Trap, and it is understandable. Suppliers worry that asking a clarifying question signals ignorance, so they default to a comprehensive, well-formatted non-answer.
Procurement teams read dozens of these proposals. A response that says nothing provocative also says nothing useful. The evaluator filters it out not because it failed, but because it blended in. In a competitive process, blending in is failing.
The alternative is not to be provocative for its own sake. It is to be specific, honest, and direct about what you see: which is exactly what most proposals avoid.
💡 Pro Tip: If the RFP permits clarifying questions, use them. Ask what triggered the process: cost pressure, a move that went wrong, a change in mobility volume. The answer tells you more about what they actually need than the document itself.
Authenticity as a Strategy for Responding to an Ambiguous RFP
Responding to an ambiguous RFP with authenticity means doing something most suppliers are reluctant to do: naming what the brief missed.
If an RFP for corporate relocation services does not mention school search, local area orientation, or the implications of the Renters' Rights Act on the current UK lettings market, that is not a reason to stay quiet on those topics. It is an opportunity to demonstrate that your expertise extends beyond the questions being asked.
A response that says "while not addressed in the brief, your employees relocating to London in 2026 will encounter a lettings market significantly affected by recent legislation: here is how we manage that" does two things simultaneously. It answers a question the buyer did not know to ask. And it signals that you are operating as a consultant, not a vendor filling in boxes.
This is the distinction that matters. A vendor answers the brief. A consultant improves it. Every authentic RFP response adleo produces includes at least one section the buyer did not ask for, because what the brief omits is usually more revealing than what it contains.
Be the Consultant, Not the Vendor
The most effective authentic RFP response is structured around what the buyer's employees will actually experience, not what the scoring matrix has space for.
Replace abstract capability claims with specific scenarios. Instead of "optimised logistics management," describe what happens on an employee's first night: whether they arrive to a connected home, a prepared property, and a named person they can call. Instead of "proactive issue resolution," give an example of the kind of problem that arises without warning in a complex move, and explain exactly how it gets resolved.
This kind of specificity serves a dual purpose. It makes the response memorable. And it gently challenges the buyer to ask whether their current provider (or the platform-first alternative they are also evaluating) could make the same claim.
💡 Pro Tip: Structure one section of your response around a scenario the RFP did not raise. Frame it as "based on what we know about the market, here is the challenge your employees are likely to face that this brief does not currently address." It demonstrates expertise, and it positions you as a partner rather than a respondent.
Practical Steps for the Blind Bid
When requirements are genuinely unclear, the following approach consistently outperforms the comprehensive-but-forgettable alternative.
Ask the why, not just the what. If clarifying questions are permitted, focus on the context behind the RFP rather than the technical requirements within it. What triggered this process? What did the previous provider fail to do? The answers shape a far more targeted response than anything in the document — including what success looks like for the person who will champion this internally.
Offer a tiered structure. When the brief is too vague for a single proposal, present two or three clearly defined options: one built around cost efficiency, one around employee experience and assignment success. Giving the buyer a framework to self-select into is more useful than attempting to cover all possibilities in a single response.
Lead with values, not features. Authenticity cannot be replicated by a platform or produced by a generative AI tool. A response that is genuinely specific to this buyer, this market, and this moment will always outperform one that is thorough and generic. The right client (the one worth winning) will recognise the difference.

What the Right Client Looks Like
One thing is worth saying plainly: an authentic response to an ambiguous RFP will not win every brief. Some procurement processes reward comprehensiveness over insight. Some buyers have already decided on price and the process is a formality. A team that did not want their brief questioned will occasionally mark down an honest, specific response.
That is an acceptable outcome. The client who values authenticity and expertise is also the client who will be a productive long-term partner. The client who wanted a polished non-answer was unlikely to be one. Responding to an ambiguous RFP with honesty is, among other things, a form of client qualification.
FAQs: Responding to an Ambiguous RFP
What is an ambiguous RFP and how common are they?
An ambiguous RFP is one where the requirements are vague, contradictory, or missing key criteria that would actually determine whether a supplier is suitable. In corporate relocation, they are very common, because procurement teams often apply a generic category framework to a service with significant human complexity. The brief covers what is measurable and leaves out what matters most.
Should you ask clarifying questions when responding to a vague RFP?
Yes, whenever the process permits it. Asking clarifying questions does not signal ignorance: it signals that you have read the brief carefully enough to notice what is missing. Focus on context rather than mechanics: what triggered the process, what the previous provider failed to deliver, and what success looks like for the person sponsoring the project internally.
How do you avoid the generic proposal trap when responding to an ambiguous RFP?
By being specific where others are vague, and by naming what the brief missed rather than silently working around it. Replace capability claims with real scenarios. Structure at least one section around a challenge the buyer did not ask about, but will encounter. The goal is to be the proposal that was clearly written for this client, not one that could have been sent to anyone.
What does an authentic RFP response look like in practice?
A genuine authentic RFP response names the gaps in the brief directly, explains why they matter, uses specific scenarios rather than abstract positioning, and offers a tiered structure if the requirements are unclear rather than a single all-encompassing proposal. The whole thing leads with values: what the supplier actually believes, and why, rather than a list of features calibrated to score well on a matrix.
How do you handle an RFP where the real requirements are missing?
Respond to the brief as written, but add a section that addresses what is missing. Frame it as market knowledge: based on your experience, here are the factors that will determine whether this programme succeeds that this brief does not currently capture. It demonstrates expertise, builds trust, and gives the buyer something to consider that no other supplier is likely to have raised.
