You open an RFQ, spend 45 minutes analyzing wall thicknesses, draft angles, and tolerances, then send a quote — only to hear nothing back. Or worse, the buyer asks why there is a $150 “engineering review” line item they never expected.
Why the Conversation Goes Sideways
Most shops treat engineering review as invisible labor baked into the unit price. When you finally break it out as a separate charge, the buyer sees a new cost they did not budget for. The fix is not to hide the work — it is to frame the charge before the quote lands in their inbox.
Separate the Diagnostic From the Production Quote
Think of engineering review like a mechanic’s diagnostic fee. You do not charge for the repair until you know what is wrong. Offer a two-step process:
- Step 1 – Paid DFM Assessment: Fixed fee (or credited toward the order) for geometry analysis, manufacturability flags, and recommended changes.
- Step 2 – Production Quote: Firm price for the revised design with the review fee applied as a credit.
This turns an unexpected line item into a logical gate the buyer chooses to pass through.
Show the Deliverable Before You Ask for Payment
Send a one-page preview: a marked-up screenshot or short PDF highlighting the top three risks (thin walls, unsupported overhangs, tolerance stack-ups). Buyers pay for clarity, not for your time. When they see concrete issues tied to cost or lead-time savings, the fee feels like an investment.
Offer a Credit, Not a Discount
“Free if you order” sounds like a trap. “$200 review fee credited 100% against your first production run” sounds like a deposit. The psychology is different — one feels like a waiver, the other like a commitment.
Tier the Fee by Complexity
Not every part needs a deep dive. Publish a simple matrix:
- Quick Check (single process, < 5 features): $75 – 24 hr turnaround
- Standard Review (multi-process, GD&T): $250 – 48 hr
- Comprehensive (assembly, material substitution, nesting study): $500+ – 72 hr
Buyers self-select. You avoid under-charging for complex jobs and over-charging for simple ones.
Automate the Routine So You Bill for Judgment
If your quoting software flags thin walls, draft violations, and minimum radii automatically, the human review focuses on trade-offs: material substitution, consolidation, finishing strategy. That judgment is what buyers pay for. Solvi’s instant quoting engine runs those automated checks in the background so your estimators only spend time on the decisions that actually move the needle. See how it works.
Put the Policy in Your Public Quote Template
Add one sentence to every quote footer: “Engineering review fee credited 100% toward production order.” No separate email, no awkward follow-up. The policy travels with the quote.
Handle the “We Have Our Own Engineers” Objection
Buyer says their team already did DFM. Reply: “Great — then this review takes 15 minutes and costs the minimum tier. If we find nothing, you’ve bought cheap insurance. If we catch one tolerance stack-up that avoids a scrap run, it pays for itself.” Frame it as risk reduction, not duplication.
Track Conversion, Not Just Revenue
Measure two numbers: review-to-quote rate and review-to-order rate. If buyers pay for reviews but never order, your preview deliverable is not showing enough value. If they skip the review and order anyway, you may be under-charging for hidden engineering time. Adjust the tiers until the funnel makes sense.
Conclusion
Charging for engineering review works when the buyer sees the deliverable first, understands the credit structure, and chooses the tier that matches their risk. Make the fee transparent, creditable, and tied to concrete manufacturability improvements — not to your hourly rate. Solvi helps you automate the routine checks so your team can focus on the high-value judgment buyers are happy to pay for. Learn more.
