1. Write a title page

This page should include details like basic info, the client's name, and the date of writing the proposal. Make sure to keep it professional and adhere brand colors.

2. Explain your "Why"

After the title page, write an executive summary including the reason to propose. Followed by problems identified with the solution you think.

3. Project your capabilities

Once you clear the reason behind the proposal, like offering a service. Write your qualifications and capabilities of service. Also, mention the pricing that you offer.

4. End with conclusion

Here the motive is to prompt further conversation with the client. So mention your availability and your vision. Also, don't forget to mention your terms and conditions.
