Sample Letter for Business Proposal: Partnership Request
Dear Dr. Patel,
As the founder of GreenTech Energy, I have been following your research on sustainable battery storage for over a year. Our game‑changing Li‑silicon cells have already reduced cost per watt by 18% and doubled cycle life. I believe that joining forces can accelerate both our missions.
We propose a partnership in three simple steps:
- Joint Pilot Project: Deploy our cells in one of your prototype stations for 12 months with zero upfront cost.
- Revenue Share: We split net profits 60/40 in your favor after covering R&D expenses.
- Co‑Branding Marketing: Co‑create press releases and case studies to reach a combined audience of 2M industry executives.
Benefits to your lab include early access to our high‑energy product, reduced equipment costs, and a shared risk strategy. To date, our early adopters have achieved a 25% increase in storage efficiency. We anticipate similar gains for collaborators.
Could we schedule a 15‑minute call on Thursday, May 10 to discuss details? I’ll send calendar invites for a 5 pm slot GMT‑4, which works for both our teams. Your insights will be invaluable as we fine‑tune the project.
Thank you for your time, and I look forward to a fruitful collaboration.

Sample Letter for Business Proposal: Service Extension Offer
Dear Alex,
I hope you’re doing well! It’s been five months since we successfully upgraded your company’s IT infrastructure. We have monitored performance and noticed that average downtime has dropped by 30%, which is fantastic. However, as your business grows, I see an opportunity to keep your operations running smoothly with a more comprehensive service package.
We’d like to propose adding Managed Cloud Support to your current contract. Key features include:
- 24/7 real‑time monitoring of all cloud resources.
- Quarterly security audits and vulnerability patches.
- Priority ticket handling with a guaranteed 90‑minute response time.
With this extension, your annual cost would increase by only 12% but could prevent potential downtime that costs up to $20,000 per incident. Clients who upgrade often report a 50% drop in support tickets within the first six months.
We’re offering a one‑month trial at no additional cost. If you’re interested, I can arrange a Zoom demo for your IT team on Wednesday, May 3 at 10 am. Let me know what works for you, and I’ll set it up.
Thank you for trusting us with your IT needs. We’re excited to help you keep moving forward.
Warm regards,

Sample Letter for Business Proposal: Funding Proposal
Dear Ms. Ramirez,
My name is Elena Torres, and I’m the founder of CleanWater Tech. We developed a low‑cost, solar‑powered water purification system that can serve 1,000 households in rural areas. We’ve already partnered with two NGOs in Peru, and have helped 12,000 people gain safe drinking water.
We are seeking $500,000 for the next 18 months to expand production, strengthen our supply chain, and replicate the model in three additional countries. Our projected financials look promising:
| Year | Revenue (USD) | Profit (USD) |
|---|---|---|
| 2025 | 1,200,000 | 300,000 |
| 2026 | 3,000,000 | 900,000 |
With your investment, we can shorten the production cycle by 25% and reduce costs by 15% through economies of scale. Moreover, we estimate that every kilogram of water purifier will prevent 30 liters of contaminated water consumption, aligning perfectly with global health goals.
Could we book a 30‑minute presentation on Monday, May 8? I’ll explain our technology in detail and walk through how your funding can create tangible, measurable impacts in underserved communities.
Thank you for considering our vision. I look forward to discussing how we can make clean water a reality together.
Sincerely,
Elena Torres
