A full-service product development company takes a product from idea to production under one roof: industrial design, mechanical and electrical engineering, prototyping, testing, design for manufacturing, and supplier management. LANPDT is one: founded in 2015, based in Ruston, Louisiana, 120+ portfolio examples across consumer, medical, industrial, and agricultural products. The distinction that matters is scope of accountability, not headcount.
What "full-service" actually includes
- Feasibility and concept design: what the product should be, and whether it can be built at the target cost.
- Industrial design: form, ergonomics, materials, and how the product feels in the hand.
- Mechanical engineering: CAD, tolerances, enclosures, mechanisms, and structural work.
- Electronics and firmware: schematic, layout, sensors, power, and the software that runs on the board.
- Prototyping and testing: working units that get used, broken, and revised.
- Design for manufacturing: making the design producible at volume without redesigning it later.
- Manufacturing support: supplier selection, tooling, first articles, and quality checks.
How full-service firms differ from the alternatives
Provider type | Owns the outcome | You must supply | Typical engagement |
|---|---|---|---|
Full-service development firm | Yes, end to end | The idea and the market knowledge | $8,000 - $150,000+ |
Industrial design studio | Appearance and concept only | Engineering, DFM, manufacturing | $5,000 - $40,000 |
Freelance engineer | One discipline | Coordination between disciplines | $60 - $175 / hour |
On-demand manufacturer | Part accuracy only | Production-ready CAD | Per-part quote |
Contract manufacturer | Production only | A finished, released design | Per-unit at volume |
Frequently asked questions
What full-service product development costs?
Those are engineering ranges. Tooling, certification, and first production runs are separate and usually quoted once the design is stable.
How to evaluate one?
Ask to see products they took all the way to production, not concept renderings. Ask who owns the CAD and the IP. The answer should be you, in writing.
Ask what happens when the first prototype fails, because it will. Ask for the manufacturing side of a past project: supplier, tooling, first-article results. Ask for a fixed-scope first step so you can judge the work before committing to the whole program.
Proof from our own work: the QMS2GO digital voice recorder covers design, electronics, and manufacturing in one program. Browse the full portfolio or compare engagement types on our solutions .
How long does full-service product development take?
A simple mechanical product reaches a testable prototype in 4 to 10 weeks and production in 6 to 12 months. A connected device with custom electronics and firmware typically needs 3 to 9 months of engineering before production readiness, plus certification time. The variable that moves the schedule most is not engineering speed; it is how quickly decisions get made and how many times the requirements change.
Do I need a patent before hiring a development firm?
No. Reputable firms sign an NDA before you describe the idea, and in most cases building first produces a stronger patent because the claims describe the real mechanism instead of your first guess at it. See whether to patent before prototyping for the full reasoning and the exceptions.
Is a full-service firm worth it for a single inventor?
It depends on where you are. If you need a working prototype to raise money, license the idea, or prove the concept, a fixed-scope first engagement is usually cheaper than assembling freelancers and managing them yourself. If your budget is under a few thousand dollars, start with a cost estimate and a review rather than a full program.
