When a quote cannot be compared

A meaningful share of quotes cannot be compared to the others in any honest way, and what the system does in those cases determines whether anybody trusts it in the cases where it can.

Key takeaways

  • A quote for a different scope is not a cheaper quote; it is a different job.
  • A single-number quote can be listed but not aligned, and the report says so.
  • Different payment terms change the real cost and are shown rather than folded in.
  • A quote that arrives after a decision is still recorded, for the next time.
  • Refusing to compare is a result, and it is stated as one.

The four cases

The four cases where a quote cannot be compared to the othersA vertical chain of five steps entered by a box labelled A quote to compare, read and normalised. Step one asks whether it is the same scope or a different job; if different it exits to Different job, shown separately. Step two asks whether there is any line detail or just one number; if just one number it exits to Cannot align, listed but not compared. Step three asks whether the terms are comparable in payment and timing; if not it exits to Shown as a difference, never folded into price. Step four asks whether it is still current, since quotes expire; if not it exits to Marked expired, kept for reference. Step five compares it, fully aligned. A note says each exit is a stated outcome on the report, not a quiet omission.AWS ACCOUNTA quote to compareread and normalisedSame scope?or a different jobDifferent jobshown separatelynoAny line detail?or one numberCannot alignlisted, not comparednoComparable terms?payment, timingShown as a differencenever folded into pricenoStill current?quotes expireMarked expiredkept for referencenoCompare itfully alignedEach exit is a stated outcome on the report, not a quiet omission.

The different-job case

This is the most valuable refusal and the easiest to get wrong. A builder who quotes eight thousand for the bathroom because they have proposed keeping the existing layout has not undercut anybody; they have answered a different question, and possibly a better one.

Presenting that as the cheapest option in a price column is a serious distortion. Presenting it in its own section headed “proposes a different approach”, with what differs listed, turns it into the useful thing it might actually be.

Payment terms are cost

Fifty per cent up front against staged payments on completion of each phase is a real difference in cash flow and in risk, and there is no defensible exchange rate between them and price. The system shows the terms as their own row and leaves the weighing to the person, which is the same principle as the missing recommendation.

The same applies to timing. A quote that can start in three weeks and one that can start in three months are not competing on price at all if the bathroom is currently unusable.

What ’not comparable’ looks like

How a quote with no line detail is presented as not comparableA horizontal row of five boxes. Quote D: one number, nine thousand two hundred. No line detail: nothing to align. Not comparable: stated plainly. Still listed, with its total. One question: can you itemise? A note says it is listed rather than hidden, so the reader can see it exists and see why it is not in the table.A QUOTE THAT WILL NOT ALIGNQuote Done number, 9.2kNo line detailnothing to alignNot comparablestated plainlyStill listedwith its totalOne question'can you itemise?'Listed, not hidden.

The temptation is to drop unalignable quotes so the table looks clean, and it produces a page that misrepresents what was received. Somebody looking at three neat columns has no way of knowing a fourth supplier quoted nine two.

Expired quotes are kept

Quotes have validity periods and they run out, usually while somebody is deciding. An expired quote is marked rather than deleted, because it is the best available evidence of what that supplier charges and it is the starting point for the next conversation.

Over a couple of years this accumulates into something more useful than any individual comparison: a record of what each supplier quoted for what, with their exclusions, which makes the fourth job easier than the first.

Refusal as a result

The theme across all of this is that the system’s outputs include “I cannot answer that”, and it says so in the same place and with the same prominence as the answers it can give. That is what makes the answers worth anything.

A comparison tool that always produces a clean table teaches people to trust clean tables. One that occasionally says “these two cannot be compared, here is why” teaches people to read the reason, which is the habit that actually protects the decision.

Next: what all of this costs to run.
