Tooling and non-recurring engineering (NRE) charges are one-time costs a supplier incurs to set up production — molds, fixtures, programming, first-article inspection. They're among the most important numbers in a quote comparison because they change the effective per-unit price entirely depending on production volume, and comparing two quotes with different tooling structures requires amortizing them correctly.
How Amortization Changes the Math
A $20,000 tooling charge amortized over 10,000 units adds $2.00 per unit; amortized over 100,000 units it adds only $0.20. This means a supplier with high tooling and a low unit price can be cheaper at high volume and more expensive at low volume than a supplier with no tooling and a higher unit price. The crossover point depends entirely on your volume, which is why NRE and setup fees must be spread across production volume to prevent hidden cost overruns.
The Comparison Problem
When suppliers quote different tooling structures — one charges tooling separately, another bundles it into a higher unit price, a third offers to amortize it over a committed volume — the quotes are not directly comparable until the tooling is normalized against your actual expected volume. A naive comparison of unit prices alone gets the ranking wrong whenever tooling structures differ.
Normalizing Tooling Automatically
The AI agent extracts the tooling and NRE charges from each quote, amortizes them across your expected volume, and folds the result into the normalized per-unit cost — so the comparison reflects the true per-unit cost at your volume, not the supplier's framing.
