Manufacturing Cost Accounting

How Do You Price an Engineered Quote?

The difference between quoting build-to-print and design-to-spec is not a markup, it is who owns the risk of the design being wrong. Price that explicitly or absorb it silently.

Quotation engineering is the work of converting a drawing package into a defensible price, and it splits cleanly into two situations that get quoted as though they were one. Build-to-print means the customer owns the design and its consequences. Design-to-spec means you do. The manufacturing cost may be identical; the risk position is entirely different, and a quoting process that does not distinguish them is systematically underpricing the second.

Engineering hours are a cost, not an overhead

Reviewing a print package, raising manufacturability questions, developing a process routing, designing fixtures, and writing an inspection plan are real hours consumed before a single part is made. Many shops absorb these into overhead, which means the customers who send complex packages are subsidized by the ones who send simple ones. Track quoting and pre-production engineering hours against the job, at a loaded rate near $41 an hour based on the current manufacturing wage of $30.35/hour (Jul 2026, BLS) adjusted for your engineering pay scale, and the subsidy becomes visible immediately.

Tooling amortization is a negotiation, not a formula

A $48,000 tool spread across a 60,000-piece campaign is $1 a part, which looks negligible until the campaign ends at fifteen thousand pieces and three quarters of the tool remains unrecovered. The three structures are customer-paid tooling, amortized-in-price with a minimum quantity commitment, and fully absorbed. Only the first two are safe without a volume guarantee, and the third is a bet on a forecast the customer made and you are carrying.

• Tooling cost: $48,000
• Assumed campaign quantity: 60,000
• Amortized per part, if the volume arrives: $1

Amortized tooling is a loan you made to a customer against a forecast they wrote. Price it as credit, because that is what it is.

Risk loading, made explicit

Load these separately so they can be discussed

• Design responsibility. If you own the design, you own the recall, and that exposure has a price that a manufacturing margin does not cover.
• Material price exposure on fixed-price work longer than a quarter, which is what escalation clauses exist for.
• Process maturity. A first-article job on an unfamiliar process deserves a contingency the tenth repeat does not.
• Volume risk, where the quoted price assumes a quantity the customer has not committed to.

Quote the assumptions, not just the number

A quote that states its assumptions is easier to defend and easier to revise. Name the quantity the price assumes, the material index and date, the tooling structure, and the lead time the capacity was reserved against. When a customer later halves the quantity, an assumption-bearing quote reprices as a matter of arithmetic. A bare number reprices as an argument, and the shop usually loses that argument because it has nothing written down.
