The clarification process is one of the most underused tools in public bidding. Most suppliers either ignore it or fire off questions that hand their thinking to competitors. Used well, it removes the ambiguity that loses marks and occasionally reshapes a tender in your favour. Used badly, it wastes your best insight on a public noticeboard.
What the clarification process is
During a live tender, suppliers can submit written questions to the contracting authority, and the authority responds within a published window. There are two directions to it:
- Supplier clarifications — your questions to the buyer about the requirement, the documents, or the process.
- Buyer clarifications — the authority’s questions to you, usually after submission, to clarify something in your bid.
The defining feature of supplier clarifications in public procurement is transparency and equal treatment: to keep the competition fair, the authority generally publishes both the question and its answer to all bidders, usually anonymising who asked. That single fact should govern how you use the process.
The golden rule: never reveal your hand
Because your question and its answer go to every competitor, a clarification can leak your strategy. Ask “would the authority view a [specific innovative approach] favourably?” and you’ve just handed your differentiator to the field. Before submitting any question, ask yourself: if a competitor read this, what would it tell them about how we intend to win? If the answer is “too much,” don’t ask it — or rephrase it neutrally.
When a clarification is worth asking
Good clarifications fall into a few categories:
- Genuine ambiguity in the requirement or specification that materially affects how you’d respond or price.
- Contradictions between documents — the ITT says one thing, the pricing schedule another.
- Process and admin — format, page limits, submission mechanics, deadlines.
- Disproportionate or restrictive criteria — occasionally a well-judged question about an eligibility requirement that seems to exclude capable SMEs can prompt the authority to reconsider it.
If a point won’t change your bid, your price, or your decision to bid, it usually isn’t worth a question.
How to phrase clarifications
- Be specific and reference the document. “Section 4.2 of the ITT states X; the pricing schedule tab 2 implies Y — which takes precedence?” gets a usable answer. Vague questions get vague answers.
- Keep it neutral. Strip out anything that signals your intended approach.
- One issue per question. Bundled questions get half-answered.
- Ask early. Authorities set a deadline for clarifications before the submission date; late questions may go unanswered, and you need time to act on the reply.
Watch the answers — even the ones you didn’t ask
Every published clarification response is part of the tender. An answer can change a requirement, confirm an interpretation, or reveal what other bidders are uncertain about. Read all of them, not just replies to your own questions, and re-check your bid against any that shift the goalposts. A clarification that changes the spec after you’ve drafted is a classic way to end up non-compliant without realising. (It’s on the tender review checklist for that reason.)
Handling clarifications the buyer sends you
After submission, an authority may come back with questions about your bid. The rules here are tighter than suppliers often assume: a clarification can correct an obvious error or explain something already in your bid, but it generally cannot let you add new information or materially improve your submission — that would breach equal treatment. So:
- Answer precisely what’s asked, and no more.
- Point to where it’s already evidenced in your bid where possible.
- Respond promptly and within the deadline — a missed clarification deadline can cost you.
- Don’t try to smuggle in improvements you wish you’d made; it can get your response rejected.
The takeaway
Treat clarifications as a precision instrument, not a conversation. Ask only what changes your bid, phrase it so it reveals nothing, read every published answer as part of the live requirement, and answer the buyer’s questions narrowly. Done well, the clarification process closes the ambiguity that quietly loses marks — without giving anything away.
Make sure your bid still scores after the clarifications land. BidReview re-scores your live response against the final requirement so a late change doesn’t catch you out. Run the free scorecard →
