Due to the “non-standard” nature of customized prototypes, the quotation needs to balance accurate cost accounting and customer psychological expectations. It is recommended to start from the following dimensions:
1. Refined cost breakdown (base price logic)
1. Prototype material cost: Calculate the blank size rather than the net weight of the part, with a 20%-30% allowance for cutting and clamping losses. For special materials (such as titanium alloy, PEEK), consider the procurement channel and minimum order quantity premium.
2. Prototype processing cost: The core lies in the “machine-hour cost”. The hourly rate is determined based on equipment depreciation, energy consumption, and tool wear. For complex structures, additional labor hours for programming, clamping, and multiple molding processes need to be accounted for.
3. Prototype post-processing cost: This is the most prone to cost overruns. Polishing, painting, and anodizing are highly dependent on manual labor. It is recommended to estimate the labor hours based on the surface area or complexity factors (such as deep holes, thin walls), and multiply by the hourly wage of skilled workers.
4. Hidden costs of prototype: including management fees (usually accounting for 10%-15% of direct costs), packaging, transportation, and risk premium (reserved with a 5%-10% floating space for highly complex trial-and-error parts).
II. Developing a quotation plan with high acceptance (strategic logic)
1. Tiered pricing: Offer two sets of solutions for “economic” prototypes and “precise” prototypes. The former adopts conventional processes and tolerances, while the latter opts for five-axis machining or imported materials. This allows customers to perceive value through comparison, rather than simply focusing on price.
2. Transparent details: Reject the vague “one-price-for-all”. List the itemized quotations for materials, processing, and post-processing, and highlight the key process difficulties. Transparency can effectively reduce customers’ defensive mentality towards “arbitrary charges”.
3. Value-added service prepositioning: Provide a free DFM (Design for Manufacturability) analysis before quoting, pointing out details in the drawings that can be optimized to reduce costs (such as avoiding unnecessary undercuts). By demonstrating professionalism, make the customer feel that the higher price is justified.
III. Summary: A reasonable prototype quotation equals hard costs plus reasonable profit plus professional service premium. Demonstrating professionalism through detailed breakdowns and offering choice through various solutions are key to addressing price sensitivity and building trust.
