Supplier quote validity vs tender validity: where a winning margin quietly expires
You priced the job in March off a transformer quote that was valid for thirty days. The client awarded in June. Sound familiar? That is a winning bid losing its margin before the contract is even signed, and nobody made a mistake. The conditions of tender make you hold your price for months. Your suppliers hold theirs for weeks. Nobody writes down what happens in between.
The fix is boring and it works: a validity register. List every supplier quote and its expiry, compare each one against the tender validity and the client's right to extend it, and choose a treatment for every quote that dies first. Finding the mismatches, cited to the quote and the clause they collide with, is document work you can hand to Elora Grid. Deciding what to do about each one stays with your estimator.
Why do winning bids lose margin before award?
Winning bids lose margin before award because the prices inside them stop being real while the bid is still open, and because everyone involved behaved reasonably.
The estimator used the best numbers available. The bid stayed open exactly as long as the conditions of tender required. The supplier did what suppliers do: held the price for as long as they could see the market, and not a day longer.
Three reasonable behaviours, one silent loss. The margin does not vanish in a dramatic moment; it leaks out through a gap between two dates that were never put side by side.
What is a validity mismatch?
A validity mismatch is the difference between how long you must hold your price to the client and how long your suppliers hold their prices to you. Put that way, it sounds too simple to be dangerous. In a live tender it hides well: the tender validity sits in one clause of the conditions, each supplier's validity sits in the fine print of its own quotation, and the two sets of dates meet exactly nowhere.
None of that is bad luck; it is how the paperwork is arranged. Nobody owns the comparison, so nobody makes it. It bites hardest on long lead electrical plant, where the gap between quoting and ordering is widest and the market moves the most.
Where does the mismatch hide in a tender pack?
Four places, and none of them is labelled price risk. The validity clause sits in the conditions of tender, usually with a right for the client to ask for more time. Clarification rounds and a BAFO stretch the programme after your quotes are already in. Each supplier quotation carries its own validity and its own re-quote terms in the fine print.
And the longest lead items, the transformers and switchgear that dominate the price, are exactly the lines the supplier holds for the shortest time. The pack does not announce any of this. You have to go and line the dates up yourself, which is precisely why it gets skipped at tender time.
Lining them up is mechanical work: read the terms on each quotation, read the validity clause, put the dates in one table. Hand the pack and the quotes to Elora Grid and it returns that table, with every mismatch cited to the quote and the clause it collides with. Which quote to re-validate and which to qualify is still your estimator's call.
Four treatments for a quote that expires first
| Treatment | What it does | When it fits |
|---|---|---|
| Re-validate | Ask the supplier to hold the price to a later named date | Before submission, for the largest lines |
| Qualify | State in the bid that named prices are held only to a date | Where the conditions of tender permit qualifications |
| Escalation provision | Price the movement through a rise and fall mechanism | Long delivery programmes, where the client allows it |
| Priced allowance | Carry the risk consciously inside the margin | Small lines, or where no other treatment is available |
- 01Build the validity register. List every supplier quote in the bid with its validity end date, taken from the quotation's own terms, not from memory.
- 02Find the tender validity. Locate the validity clause in the conditions of tender, including any client right to extend, and note the realistic award window.
- 03Flag every mismatch. Mark each quote that expires before the award window closes; these are the lines carrying silent price risk.
- 04Choose a treatment per flagged quote. Re-validate, qualify, apply an escalation provision, or carry a conscious allowance; the choice is commercial and stays with the estimator.
- 05Revisit on every extension. A BAFO round or an extended validity re-opens the register; re-check every flagged line before you re-confirm your price.
Common questions
What is a tender validity period?
A tender validity period is the time your bid must remain open for acceptance after submission, stated in the conditions of tender. Until it lapses, you are generally not free to change or withdraw your price, which is exactly why supplier prices that expire inside it are a risk.
Can you qualify supplier price validity in a bid?
Usually yes, subject to the conditions of tender. A qualification stating that certain prices are held only to a named date moves the risk to the negotiation table instead of leaving it silently inside your margin. Check whether the conditions treat qualifications as grounds for non-conformance before relying on one.
What happens when the client extends the tender validity?
An extension re-opens the whole question. Every supplier quote in the bid ages by the extension period, so the validity register should be re-checked line by line before you agree to hold your price, and the extension response is a legitimate place to re-state validity qualifications.
Can Elora Grid find validity mismatches for you?
Yes. You hand over the tender pack and the supplier quotations, and it returns the validity register with every mismatch cited to the quote and the clause it collides with, each traced to its source document and page. The treatment decisions stay with your team.
