PRODUCT DEVELOPMENT PROPOSAL
The engagement runs across three phases. Each closes with a written deliverable and a review before the next begins.
PHASE 1 · DISCOVERY + SPEC
Stakeholder interviews, user research, competitive review, and a discovery workshop that produces a written product spec, MVP scope, and success metrics your team signs off on.
PHASE 2 · DESIGN + PROTOTYPING
Information architecture, user flows, high-fidelity UI, and a lightweight design system, delivered as interactive prototypes we can test with real users before engineering begins.
PHASE 3 · BUILD + LAUNCH
Full-stack engineering across two-week sprints, code review and automated testing, launch support during the first two weeks in production, and a documented handoff to your internal team.
Not included: infrastructure and hosting costs, ongoing engineering support after handoff, marketing and growth work, and third-party API or software subscription fees. New scope can be added in writing at any time.

The Product Development Proposal template is a five-page document for putting your engagement on paper before it starts. It carries an overview with stat cards, objectives, a three-phase scope of work, an investment table with a computed total, and an acceptance page with inputs and signatures.
It is intentionally simple: rename what needs renaming in Bonsai, list your actual deliverables, and set the price. Merge fields handle the client details and date, and the last page collects a PO number, start date, and both signatures.
Everything below comes pre-configured. Turn sections on or off, edit the copy, or add your own — Bonsai remembers your choices for next time.
Can I edit every section? Yes — every heading, paragraph, stat, table row, and signature block is fully editable in Bonsai.
Can I add more pages? Yes — add, reorder, or duplicate pages once the template is open.
Do merge fields auto-fill? Yes — Sender, Receiver, and Date pull from your client contact and the current date automatically.
