What does product design actually cost?

We won't quote figures in an article — any number honest enough to publish would be too vague to plan on, and your product changes every line of it. What we can do is show you the drivers, so the quotes you gather make sense and the cheap one stops being automatically attractive.

The drivers that move the number

Scope depth: a form refresh of an existing product and a from-scratch device with electronics, software and regulatory obligations are different projects wearing the same sentence. Evidence burden: how much proving does your risk profile demand — quick concept validation, or instrumented prototype rounds and human-factors documentation a submission can hold? Disciplines touched: each of industrial design, engineering, software and visualization added multiplies coordination, which is exactly why we run them as one team rather than a vendor chain — the chain's handoffs are a cost line nobody quotes. Iteration appetite: certainty is bought in loops; more loops, more cost, less risk. Production intent: "make it look right" and "make it ready for tooling in China" end at very different finish lines.

Why the cheap quote is often the expensive one

Quotes diverge mostly on what they quietly exclude: the engineering to make the render mouldable, the test round that finds the failure before tooling does, the documentation production needs. The excluded work doesn't disappear — it resurfaces later at change-order prices, or worse, in tool steel. Compare quotes by deliverables and evidence, not by the bottom line, and ask each studio what happens when a loop's answer is "this direction is wrong."

Structures that keep spend honest

Fixed-fee discovery sprints to buy certainty before commitment. Gated loops, each scoped and priced, with real go/no-go decisions — momentum never running on faith. And engagement models sized to the actual question, which is how our process is built. The budget conversation belongs at the start, in the brief — a studio that designs scope to your number honestly is worth ten that discover overruns for you.
