How should a shop quote inventors and startups (one-offs, NDAs, payment risk)?

Your part priced in about 90 seconds, no account.

Stage the work as paid drawing review, NRE, machining, inspection, and shipment; use deposits and change-order gates when scope or payment risk is high.

The direct answer

For a first prototype, collect $300 drawing and NRE before buying $180 material and scheduling $650 machining. A deposit protects both sides while the design changes.

Test the decision against the shop evidence in this example: For a first prototype, collect $300 drawing and NRE before buying $180 material and scheduling $650 machining.

Carry the measurable input from the worked case into the estimator's notes: For a first prototype, collect $300 drawing and NRE before buying $180 material and scheduling $650 machining.

Evidence from a shop floor

Two hours drawing cleanup ($220), one hour workholding design ($95), $85 material, and $464.53 machining total $864.53; a 50% deposit is $432.27. Send prototype terms before detailed estimating and keep NDA, ownership, payment, and manufacturing scope distinct.

Keep the commercial decision tied to the evidence, including for a first prototype, collect $300 drawing and nre before buying $180 material and scheduling $650 machining.

The handoff is complete only when the owner can restate the route without losing for a first prototype, collect $300 drawing and nre before buying $180 material and scheduling $650 machining.

Build the quote route

Define drawing ownership, revision control, deposit trigger, NRE deliverable, prototype acceptance, and change-order path.

A useful review question is whether the current RFQ still matches this route: define drawing ownership, revision control, deposit trigger, nre deliverable, prototype acceptance, and change-order path.

The next estimator should be able to challenge the assumption behind this route: define drawing ownership, revision control, deposit trigger, nre deliverable, prototype acceptance, and change-order path.

Use the source notes to date the assumption and record why this route was selected: define drawing ownership, revision control, deposit trigger, nre deliverable, prototype acceptance, and change-order path.

Release and learn

A promising prototype can still lack a production buyer; keep payment and scope gates explicit.

If the buyer asks for a different outcome, explain the boundary in these terms: a promising prototype can still lack a production buyer; keep payment and scope gates explicit.

Before changing the total, verify whether the caveat applies: a promising prototype can still lack a production buyer; keep payment and scope gates explicit.

A customer-facing explanation should make the risk legible: a promising prototype can still lack a production buyer; keep payment and scope gates explicit.

Close the loop by noting the evidence that would make this estimate obsolete: a promising prototype can still lack a production buyer; keep payment and scope gates explicit.

Keep the commercial decision tied to the evidence, including for a first prototype, collect $300 drawing and nre before buying $180 material and scheduling $650 machining.
