20% Existing-Supplier Spread Estimator
Start with the real 20% case: around 10 existing suppliers, recurring products, and different negotiated invoice prices for items you already buy.
Illustrative only. We verify the real 20% opportunities from recent invoices and your negotiated supplier prices.
Estimated annual upside inside your supplier network
This is not an external supplier quote or commodity forecast. It models the cost of choosing the familiar supplier when another current supplier may already have a better negotiated price for the same recurring item.
How to read the number this calculator gives you
TL;DR
- The estimate is a spread between suppliers you already pay — not an outside quote.
- It only becomes real when your actual invoices show the same item at two different negotiated prices.
- Treat it as a screening question for an invoice review, never as a savings projection.
- The two sliders are your only inputs — spend and spread — and both come from your own invoices.
- It is a screening number for an invoice review, not a quote or a forecast.
Worked example: one item, two prices
Say you buy 40 cases of crushed tomatoes a month. Your produce wholesaler invoices them at €18.40; your broadline supplier lists €16.90 for the same pack. That €1.50 spread on one recurring line is €720 a year — before you touch any other product. Multiply that pattern across ten suppliers and dozens of recurring items and the 20%-of-spend question stops being abstract. The calculator models exactly this: monthly spend times a tested spread, annualized.
FAQ
Where does the default spread come from?
From the recurring pattern we see in real invoice reviews: same items, several existing suppliers, negotiated prices that were set at different times and never re-aligned. The slider exists so you can test your own range, not to promise one.
Why can't this be an external comparison?
Because no external supplier is involved. The whole point is that better prices already exist inside the network you pay today — the estimator sizes that internal gap, nothing more.
What would make my number wrong?
Two things: testing a spread your invoices don't actually show, and ignoring pack-size differences between suppliers. An invoice review against real documents is what turns the estimate into verified numbers.
Is this a savings guarantee?
No. It is illustrative only — the note under the form says the same thing. Real numbers come from verifying recent invoices and your negotiated prices, which is exactly what the review does.
What is the 'monthly spend' number?
It is the total you currently pay existing suppliers each month — produce, dry goods, packaging, whatever the sliders cover. It is the base the spread applies to, not a target or a forecast.
What spread should I actually use?
Start at 8% and move the slider toward 20% only if your recent invoices show the same item at meaningfully different negotiated prices across two or more existing suppliers. If your invoices never show that, the honest spread is smaller — the calculator does not push you toward a number.
Does the calculator include packaging or labor?
No. It models only what you pay for the same recurring item at different existing-supplier prices. It never adds a margin, never subtracts labor, and never quotes an external supplier.
Can I trust the annual figure?
Treat it as an annualized illustration of the tested spread on the tested spend — a screening number for an invoice review, not a quote, a forecast, or a savings guarantee.
Why does the result card say 'illustrative only'?
Because the number changes the moment your real invoices and negotiated prices enter the review. The card stays honest: it sizes the question, the review sizes the answer.
