Product development / INSIGHTS
How much does it cost to develop a physical product?
The cost of developing a physical product depends on what needs to be designed, tested and prepared for production. A concept study, a functional prototype and a production-ready package are different scopes. To establish a useful budget, define the finish line, the technical risks and the work already completed before comparing proposals.
Define the finish line before the budget
A concept presentation, a working prototype and a production-ready package are different purchases. A concept can explain the opportunity without resolving material shrinkage, assembly time or the supplier’s inspection process. Ask each prospective partner to quote against the same finish line.
For a small consumer accessory, production readiness might mean released CAD, drawings, a bill of materials, approved appearance samples and an agreed inspection plan. For an electronic product, firmware, electrical engineering, testing and component sourcing add separate workstreams.
Build a budget by stage
Separate the development work into stages so you can see what each proposal actually covers. MILOSSI scopes design and development around the individual brief; there is no standard fee implied by the stages below.
For each stage, agree the deliverables, review rounds, responsibilities and acceptance criteria. Confirm whether supplier coordination, testing support and changes after approval are included or quoted separately.
| Workstream | What the scope should establish | What changes the effort |
|---|---|---|
| Research and product definition | Users, requirements and target unit cost | Quality of the existing brief and feasibility questions |
| Concept and industrial design | Directions to explore and refinement rounds | Product complexity and number of alternatives |
| Mechanical development and DFM | Parts, interfaces and supplier review | Mechanisms, tolerances and manufacturing process |
| Prototype rounds and validation | What each sample must prove | Materials, quantity, test methods and iterations |
| Tooling and production setup | A separate supplier scope and release criteria | Geometry, output, finish and acceptance requirements |
A worked scope: a two-part desk accessory
Consider a desk accessory with an upper shell and a weighted base. An initial phase might define the user, dimensions and visual direction. Engineering then resolves the assembly, material selection, stability and surface finish. Prototype rounds test whether those decisions work together.
The development proposal should identify those deliverables and the intended review rounds. The manufacturing quotation should separately cover tooling, first-order quantity and quality requirements. Packaging, freight, testing and launch activity need their own allowances. This separation lets you compare complete scopes without confusing a design fee with the cash needed to reach the first sale.
If an unproven hinge is added to the accessory, the brief changes: it may need mechanism development, additional samples and durability testing. Revisit the scope before committing to the next phase rather than assuming the original proposal covers a different product.
What moves the price most
Parts count is only a starting point. A single cosmetic enclosure with demanding finish requirements can take more work than several uncomplicated internal pieces. Novel mechanisms, water sealing, tight interfaces and changes after tooling release all increase uncertainty.
- Separate must-have functions from features that can wait for a second version.
- Agree the number of prototype rounds and what each round must prove.
- Define ownership and delivery formats for CAD, drawings and tooling.
- Ask what supplier coordination, test support and post-launch changes cost.
Ask for a phased proposal
Send the product’s purpose, intended user, reference dimensions, target retail and manufacturing costs, first-order quantity, sales markets and launch date. State what already exists: sketches, CAD, a prototype or a supplier quotation.
A paid definition phase can be the right first commitment when the product is still uncertain. Its output should be a scope, risk list and cost model that make the next investment easier to judge. Compare proposals on the decisions they resolve, not just their page count.
Common questions
Does the development budget include manufacturing?
Not automatically. Separate design and engineering fees from tooling, validation, first production, freight and launch costs. Ask for written inclusions.
Can I start with a smaller budget?
Yes, by narrowing the first phase to requirements, feasibility or one critical prototype. A smaller first phase does not establish the full cost of reaching production.
