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

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.
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.

A cheaper quote with worse payment terms can cost more than it saves.
The approval ladder that decides who signs off also decides how much comparison shopping a purchase deserves.
Different quantities or specifications make a price comparison meaningless until you adjust them to the same quantity and specification.
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.
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.
| Purchase Size | Typical Practice |
|---|---|
| Small, routine | One trusted, already-approved supplier is often fine |
| Moderate | At least two quotes, both from approved suppliers |
| Large or unusual | Three 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.

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.
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.
As the example story shows, the full deal (terms, lead time, quality) can matter more than the sticker price.
Removes any real comparison at all, even a quick second quote provides a useful reference point.
Different quantities, specifications, or delivery terms make a price comparison meaningless, adjust them to the same quantity and specification first.
For your next moderate-or-larger purchase, request at least two quotes and complete the comparison table in Section 3 before deciding.
