Renders can look convincing, but the real risk shows up later, when tooling, tolerances, parting lines, and material choices start pushing back. A product design proposal gives a buyer something concrete to agree to before prototypes and molds get expensive, and it explains how the work moves from early direction into buildable CAD and manufacturer-ready notes, with headings in Raleway over Inter and a sharp enamel-red and slate-blue palette.

The sections read like a guided handoff plan: The short version frames the goal in production terms, then How we work explains how constraints get confirmed early and how reviews happen through form exploration and CAD. Confirmed design brief and Prototype plan and test notes name what gets produced and what gets checked before cutting steel, then the later pages cover what you need from the client, how existing CAD gets handled, and how feedback gets consolidated so decisions don’t drift.

  • The short version Opens with the production outcome and the path from early direction to geometry, materials, and assembly that work in manufacturing.
  • How we work Explains how constraints get confirmed early, then how form exploration and CAD build move through review points.
  • Pricing Holds the single priced option and the scope description you match to your own numbers before sending.
  • Getting started Carries the acceptance signature and fee summary, including the 30% booking payment tied to signing.
  • Payment States the 30/70 invoicing split, 14-day terms, what inputs the client has to provide, and what happens when scope changes.

Once the proposal is in your workspace, you replace the numbers for Launch Ready, send it to a client, and they accept and sign online. The Getting started section also ties acceptance to a 30% booking payment, so the start steps are clear at the moment they say yes.

We went from spending hours on every proposal to creating fully customized ones in under 5 minutes. That's not an exaggeration - we timed it.

What to include in a product design proposal

PartWhat it covers

The short version

Summarises the outcome the buyer is trying to secure and the stages that take the work from early direction into production-minded CAD and checks before tooling.

About us

Introduces the studio and explains how industrial design decisions stay connected to CAD, assembly approach, and DFM notes as changes happen.

Who you will work with

Clarifies who stays involved from the first sketch through handoff, so the buyer knows who they’ll be dealing with across the project.

Team

Names the two roles and what each one handles, from ergonomics and form decisions through CAD surfacing and tooling constraints.

Selected work

Gives context for the kind of product design jobs shown next, focused on moving from early direction to CAD, prototypes, and manufacturing handoff.

Portfolio

Shows example project snapshots and the kinds of manufacturing and assembly problems that got solved on the way to buildable CAD.

How we work

Describes the working approach around making constraints visible early, then moving through brief workshop, form exploration, and CAD with planned reviews.

Confirmed design brief

Defines the written brief and the deliverables that follow, including concept directions and production-minded CAD for parts and assembly.

Prototype plan and test notes

Covers what gets documented during a prototype round, plus the DFM support package and the CMF specification pack for supplier matching.

Pricing

Includes a priced items table for the single option, which you update with your own pricing before sending.

Getting started

Carries a signature section and a fee summary, and ties acceptance to booking the first workshop and the 30% payment step.

Payment

Spells out the 30/70 invoicing timing, 14-day terms, the inputs needed to start, how existing CAD gets handled, and how scope changes get managed.

Feedback and approvals

Explains when reviews happen, how feedback gets consolidated, what’s included for prototype rounds, and how manufacturer coordination and feedback review works.

Who it is for

Industrial designers and product design studios quoting industrial & product design work for consumer products, furniture design, or prototyping support before manufacturing.

The proposal in full

The short version

You’ll have a design your manufacturer can quote and build without guessing, with CAD that matches how parts split, assemble, and feel in-hand, plus clear notes on what must be checked before cutting steel.

You’re coming to us to move from a rough direction or an early prototype to geometry, materials, and assembly that work in the real world. Next, we’ll confirm constraints, then start form exploration.

We start by locking down the constraints that drive everything later, including target cost, materials, key interfaces, and what has to stay from existing work. Then we explore form and ergonomics, build production-minded CAD, and pressure-test it against draft, parting lines, tolerances, fasteners, and assembly before it ever reaches a toolmaker.

About us

We’re a two-person industrial design studio. Émilie Bouchard leads industrial design, so the early work answers real questions about grip, reach, safety, and how the product reads on a shelf. Marc-André Gagnon leads CAD surfacing, so the forms you approve become buildable geometry with controlled split lines and surfaces that hold up under tooling constraints.

Clients bring us in when the risk is not the idea, but the handoff. We keep decisions connected, so a change in form updates the CAD, the assembly approach, and the DFM notes together. We’ll also tell you when a feature is likely to cost you later, because draft angles, shutoffs, and tolerance stack-ups don’t care how good a render looks.

Who you will work with

You’ll work directly with the two of us, and you’ll see the same people from the first sketch through factory handoff.

Team

Émilie Bouchard, Industrial designer. Émilie runs the brief workshop and the form and ergonomics exploration, then translates what you pick into decisions we can defend in CAD and prototypes.

Marc-André Gagnon, CAD surfacing lead. Marc-André builds the CAD and Class-A style surfacing, and he’s the one sweating parting lines, draft, ribs, bosses, and what the tool will actually do.

Selected work

Here are a few recent product design jobs that went from early direction to CAD, prototypes, and a clean handoff to manufacturing.

Portfolio

Handheld appliance redesign. We reworked the grip, button placement, and enclosure split to fix assembly issues and reduce visible mismatch at the seam. The final CAD supported two housing materials and a simplified fastener strategy for faster builds.

Consumer electronics enclosure. We rebuilt the enclosure around an existing PCB and connector set, then tuned the external surfaces so the split line followed the form without undercuts. The DFM pass removed side-actions by changing internal snaps and clearances.

Personal care product mechanism. We took a working prototype and turned it into a manufacturable assembly with defined fits and wear surfaces. The prototype round focused on feel, latch reliability, and tolerance stack-up before any tooling quotes went out.

“Their CAD matched the factory reality, and the prototype behaved like the final product.”

How we work

This kind of work goes best when we make the tricky constraints visible early. We’d rather flag draft, splits, fasteners, and tolerance risks in week one than discover them after a prototype round or, worse, after a tooling quote.

1. Brief workshop Week 1 We run a working session to lock constraints you can measure: target cost, materials, key dimensions, compliance needs, what must stay from existing CAD or prototypes, and the decisions your manufacturer will ask about. You leave with a confirmed brief and a list of open questions we need answered to start CAD safely. 2. Form exploration Weeks 1-2 We explore form, ergonomics, and product architecture in parallel. You’ll review options that show size, grip, reach, interface layout, and how the product breaks into parts. We’ll ask for quick decisions here, because a chosen direction is what keeps later surfacing and DFM from turning into rework. 3. CAD and detailing Weeks 2-5 We build production-minded CAD, including split lines, internal structure, fastening approach, and the surfaces that control how parts meet. If you have existing CAD, we can work from it when it is structurally sound, or rebuild when it fights manufacturability. You’ll see checkpoints where we confirm fit, clearances, and assembly order. 4. Prototype and handoff Weeks 5-7 We plan a prototype round that matches the risks, then capture test notes that feed directly back into the CAD. After that, we do a DFM pass and prepare the handoff package your manufacturer expects. If manufacturer feedback comes in during quoting, we’ll review it with you and adjust the design without losing the original intent.

Confirmed design brief

A written brief with the constraints, priorities, and open questions captured in one place, so the design, CAD, and manufacturer conversations stay aligned.

CONCEPT DIRECTIONS

A set of form and ergonomics directions with clear differences, shown with enough views and scale context to make a decision without guessing.

PRODUCTION-MINDED CAD

3D CAD for the parts and assembly, built with split lines, internal structure, and interfaces that reflect how the product will actually be made and put together.

Prototype plan and test notes

A plan for the prototype round and the notes that come out of it, including what was tested, what changed, and what still needs confirmation before tooling.

DFM SUPPORT PACKAGE

Manufacturing notes that call out draft intent, parting line assumptions, fits, fasteners, and risk areas, written so a factory can quote and comment without a long back-and-forth.

CMF SPECIFICATION PACK

A CMF pack covering colours, materials, finishes, and key appearance surfaces, with callouts that help your supplier match what was approved.

Pricing

These options cover the same product design process, with different depth in form exploration, CAD detailing, and prototype support depending on where you are before tooling.

Priced items

Getting started

If you’d like us to hold time for your product design work, the fastest path is to sign and book the first workshop.

1. Sign the proposal to confirm scope and pricing. 2. Pay 30% to book the work and reserve the start date. 3. Send any existing CAD, prototype files, and constraints so we can prep the workshop.

Signature

Fee summary

Payment

To book the work, we invoice 30% when the proposal is signed. The remaining 70% is invoiced when the finished work is handed over. All invoices are payable within 14 days.

What we need from you. We’ll start once you send a brief, target cost range, and any must-keep constraints (key dimensions, components, standards, branding). If those inputs change midstream, the schedule and scope move with them.

Existing CAD. We can work from your existing CAD or rebuild it, depending on file quality and what needs to change. We’ll confirm the approach in the brief workshop after we’ve opened the files and checked surfacing and feature history.

Changes to scope. If you add requirements after the brief is confirmed, we’ll spell out the impact before we do the extra work: what changes in CAD, what it means for prototyping, and any added time and fees.

Feedback and approvals

You’ll get review points at the end of form exploration, during CAD build, and after prototype notes. We need one decision-maker to collect internal input and send one set of notes per review to keep momentum.

Prototype rounds. Each package includes one prototype plan and test-notes pass, and we’ll support a prototype round as described in the package. Additional prototype rounds are common, and we’ll quote them once the first build method is chosen.

Manufacturer coordination. We can join calls with manufacturers and review their feedback against the CAD and DFM notes. If a factory proposes changes, we’ll translate them into design tradeoffs: cost, tooling complexity, assembly risk, and appearance.

Ownership. Once the final invoice is paid, you own the finished work we hand over for product design, including the agreed CAD, CMF specification pack, and DFM support package. Our working files and unused concepts stay with us.

Questions about this proposal template

What should a product design proposal include?

A product design proposal usually includes the scope and deliverables, how the work will run, pricing, payment terms, feedback and approval points, and a way to sign off to start. This template also covers prototype plan and test notes, DFM support notes, and a CMF specification pack as described in the deliverables sections.

What do you need from a client to start product design work?

The proposal asks for a brief, a target cost range, and any must-keep constraints like key dimensions, components, standards, or branding. The payment section also notes that changes to those inputs can shift scope and schedule.

Can a product design studio work from existing CAD files?

The payment section says the studio can work from existing CAD or rebuild it depending on file quality and what needs to change. The approach gets confirmed after the files get checked for surfacing and feature history.

How many prototype rounds should a product design project include?

The feedback and approvals section says each package includes one prototype plan and test-notes pass, with support for a prototype round as described in the package. The same section notes that additional prototype rounds are common and get quoted once the first build method is chosen.

Do product design proposals include manufacturer coordination?

The feedback and approvals section includes manufacturer coordination, including joining calls and reviewing factory feedback against the CAD and DFM notes. The same section frames proposed factory changes as tradeoffs like cost, tooling complexity, and assembly risk.

When is the deposit due for product design work?

The getting started and payment sections say the booking payment is 30% when the proposal is signed, with the remaining 70% invoiced at handover. The payment terms also state that invoices are payable within 14 days.
