The Golden Rule

Compare the whole deal, not just the number at the bottom.

Getting one quote and accepting it is guessing. At least two or three quotes, judged on the same criteria, turns a purchase into a decision.

PriceThe number everyone compares first, and the easiest one to be misled by.
Lead time & termsHow fast it arrives and when you must pay change what a price actually costs.
QualityFrom trial or reputation, the criterion a spreadsheet can't fill in for you.

One quote is guessing

At least two or three quotes, compared on the same criteria, turns a purchase into a decision.

Price isn't the whole deal

A cheaper quote with worse payment terms can cost more than it saves.

Match effort to size

The approval ladder that decides who signs off also decides how much comparison shopping a purchase deserves.

Only compare equal offers

Different quantities or specifications make a price comparison meaningless until you adjust them to the same quantity and specification.

Definition

Imagine two quotations arrive for the same fabric order. One is noticeably cheaper. The other costs slightly more but offers 60-day payment terms instead of the cheaper supplier's demand for payment within 7 days. Judged on price alone, the cheaper quote wins easily. Checked against the cash flow forecast, the business simply doesn't have the cash to pay in 7 days without straining payroll that month, so the 60-day terms are worth more than the entire price difference. The number at the bottom of the page was never the whole story.

A quotation is a supplier's written offer to sell specific goods at a specific price, under specific terms. Comparing quotations means judging multiple offers fairly, on more than price alone, before committing to one.

In One Sentence

Getting one quote and accepting it is guessing. Getting at least two or three quotes, compared on the same criteria, turns a purchase into a decision. And the cheapest number on the page is rarely the same thing as the best deal, Chapter 1's approval criteria apply here just as much as to the supplier relationship itself.

How Many Quotes, and From Whom

Purchase SizeTypical Practice
Small, routineOne trusted, already-approved supplier is often fine
ModerateAt least two quotes, both from approved suppliers
Large or unusualThree or more quotes; consider a new supplier alongside existing ones

The size cut-off for "moderate" and "large" should match your Volume 11 approval ladder, the same discipline that decides who can approve a spend also decides how much comparison shopping that spend deserves.

Memory Trick

Compare the whole deal, not just the number at the bottom. A lower price with a longer lead time or worse payment terms can cost more than it saves, exactly Volume 07, Chapter 9's payment-terms lesson, from the buying side instead of the selling side.

Example Story: The Quote That Looked Cheapest

Here's the full version of the two-quotations story from the start of this chapter.

Two quotations arrived for the same fabric order: one noticeably cheaper, one slightly higher but offering 60-day payment terms instead of the cheaper supplier's 7-day requirement. Measured on price alone, the cheaper quote won easily. Measured against Volume 07's cash flow forecast, the 60-day terms were worth far more than the price difference that month, the business simply didn't have the cash to pay in 7 days without straining payroll. The full comparison, not just the price column, made the right choice obvious.

Common Mistakes

Common Mistake #1: Comparing on Price Alone

As the example story shows, the full deal (terms, lead time, quality) can matter more than the sticker price.

Common Mistake #2: Only Ever Getting One Quote

Removes any real comparison at all, even a quick second quote provides a useful reference point.

Common Mistake #3: Comparing Quotes That Aren't Actually Equivalent

Different quantities, specifications, or delivery terms make a price comparison meaningless, adjust them to the same quantity and specification first.

Quiz Yourself

Quiz 1
Why is comparing quotes on price alone risky?
Because lead time, payment terms, and quality can matter more than the price difference, a cheaper quote with worse terms can cost the business more overall.
Quiz 2
How many quotes should a large or unusual purchase typically get?
Three or more, potentially including a new, not-yet-used supplier alongside existing ones.

Practice Exercise

Quick Summary

Quick Summary

  • Get at least two or three quotes for anything beyond a small, routine purchase.
  • Compare the whole deal, price, lead time, payment terms, quality, not price alone.
  • Ensure quotes are actually comparable (same quantity, specification, terms) before judging them.
