Software Development Proposal

Prepared for: [Client name / company] Prepared by: [Your name / studio] Date: [Date] Valid until: [Date + 30 days]

---

1. Executive summary

[In 3–4 sentences: the core problem, the system you propose to build, the headline outcome, and the high-level cost and timeline. Write this last; the decision-maker reads it first.]

2. Problem and objectives

[Describe the client's current situation and the cost of the problem — time lost, errors, manual effort, risk. Then list the measurable objectives this project must achieve.]

• Objective 1 — [specific, measurable target]
• Objective 2 — [specific, measurable target]
• Objective 3 — [specific, measurable target]

3. Proposed solution and architecture

[Explain the system in plain language, then summarise the high-level architecture: client, API, data store, background processing, and any third-party integrations.]

• [Component 1] — [what it is and which objective it serves]
• [Component 2] — [what it is and which objective it serves]
• [Component 3] — [what it is and which objective it serves]

Integrations: [List external systems you will connect to, e.g. payments, email, accounting.]

4. Scope

In scope

• [Feature / capability 1]
• [Feature / capability 2]
• [Feature / capability 3]

Out of scope (this engagement)

• [Excluded item 1 — e.g. native mobile app]
• [Excluded item 2 — e.g. data migration from legacy system]
• [Excluded item 3 — e.g. single sign-on]

5. Delivery plan

[Iterative sprints grouped into phases. Each phase ends in something the client can see and accept.]

Phase	Focus	Key outputs	Duration
1	[Discovery & design]	[Specification, designs, backlog]	[1–2 weeks]
2	[Foundation]	[Auth, data model, core API]	[2–3 weeks]
3	[Core features]	[Primary workflows usable]	[3–4 weeks]
4	[Hardening & launch]	[Testing, fixes, deployment, training]	[2 weeks]

Cadence: [e.g. two-week sprints with a demo and feedback session at the end of each.] Client commitments: [Timely reviews, test data, a named decision-maker, environment access.]

6. Team and technology stack

Role	Name	Responsibility
[Lead engineer]	[Name]	[Architecture, key implementation]
[Developer]	[Name]	[Feature delivery]
[Designer]	[Name]	[UI/UX]
[Project lead]	[Name]	[Communication, scope management]

Stack: [Language & framework, database, hosting/cloud platform, key services — and a one-line reason for each major choice.]

7. Pricing and milestones

Pricing model: [Fixed price | Time & materials with a budget cap | Fixed-price phases + T&M discovery]

Milestone	What the client receives	Payment
[Kickoff]	[Signed proposal, discovery booked]	[$ / % deposit]
[Prototype]	[Working core demonstrated]	[$ / %]
[Feature complete]	[All in-scope features usable]	[$ / %]
[Launch]	[Deployed, trained, handed over]	[$ / %]
Total		[$]

Rate (if T&M): [$X / hour or / day] Payment terms: [e.g. invoices due within 14 days.]

8. Assumptions and risks

Assumptions

• [e.g. Client provides brand assets and content by the start of Phase 2.]
• [e.g. Third-party APIs are available and documented as published.]

Risks and mitigations

Risk	Likelihood	Mitigation
[Integration unknown]	[Med]	[Spike in discovery; T&M bucket]
[Scope change]	[Med]	[Change-order process from §4 boundary]

9. Warranty and support

[Warranty window for defect fixes after launch — e.g. 30 days. Then describe optional ongoing support: maintenance retainer, response times, hosting management, and what handover includes (source code, documentation, credentials).]

10. Next steps

[One clear action. e.g. "To proceed, sign below or reply to this email and we'll send the kickoff invoice and schedule the discovery workshop."]

Optional sections

• Case study: [A comparable system you have delivered and the result.]
• Reference architecture: [Link to a fuller technical specification once scope is agreed.]
• Terms: [IP ownership on final payment, confidentiality, dependencies on the client.]
