PlantBench / Vendor quote vs. ROI case
What a vendor quote is, and what an ROI case is
A quote says what a machine costs and what is included. An ROI case says whether that cost is earned back from this plant's hours, loss, and rates. They are different documents. PlantBench only builds the second one, from inputs you can edit.
What is a vendor quote for?
A quote is the seller's document. It can state scope, specifications, and terms. It does not know this plant's crew hours, loss at the step, power and gas rates, or how many weeks the line runs.
PlantBench does not write quotes and does not name or rank equipment makers. Equipment cost on the worksheet is blank until you type it.
What is an ROI case for?
An ROI case on this site is the worksheet: labor, yield, waste, energy, maintenance, downtime, and water, then simple payback, NPV, discounted payback, and IRR after you enter equipment cost. Capacity, quality, and an avoided rebuild count only when you enter them.
The PDF marks a prefill you did not type as "(default — not entered)". A value you typed is unmarked. That is how finance can see which lines are still assumptions.
What should you check before the meeting?
Keep the quote for the price and the scope. Build the case from the plant's own hours, loss, and rates, or edit every default until you can defend it. The methodology page lists each default and its source.
If the only support for a savings line is the seller's brochure, replace that line before the meeting. The worksheet will not do that for you.

Questions
Does PlantBench replace a vendor quote?
No. A quote is the seller's price and scope. PlantBench is a free worksheet for the buyer's operating math. It is not a bid.
Where do the savings numbers come from?
From the inputs on the sheet. Labor, yield, and energy are separate lines. The worked example on each calculator is the output of that page's defaults with no state selected.
