Editable & Interactive Proposal Templates to Impress Investors, Partners & Donors

The quality of your proposal can mean the difference between gaining momentum or being forgotten. Decision-makers are busy and overwhelmed with pitches every day. If your proposal feels rushed, cluttered, or looks like every other static PDF in their inbox, it’s likely to be skimmed, or worse, ignored.

Research shows that decision-makers retain 55% more information when visuals are included instead of text alone, and proposals with professionally designed visuals are rated 30% more favorably in terms of credibility.

That’s where Flipsnack comes in. Instead of settling for dull layouts, you can start with professional, interactive proposal templates that are built for impact. These templates don’t just make your proposal look good—they turn it into a flipbook, an interactive format that feels like flipping through a real document, but online. Beyond the design, Flipsnack helps you tell your story with clarity, add interactive elements to keep your audience engaged, and track how each proposal is received.

A strong proposal needs more than good content, it has to capture attention, be easy to follow, and leave decision-makers with confidence in your vision. That’s exactly what Flipsnack helps you do. You can upload an existing PDF, start from scratch, or choose one of our interactive proposal templates as your foundation. 

Using our Design Studio, you can easily edit text, swap images, apply your brand colors, and even add interactive elements like videos, buttons, forms, or slideshows. Once your proposal is ready, share it and see in real time who viewed it, what they clicked on, and how long they engaged with each page.

To help you get started faster, we’ve curated six ready-to-use templates, each crafted for a specific scenario, from winning over investors to securing event sponsors. 

1. Editable investor pitch deck template

When you’re pitching to investors, every slide matters. They see hundreds of decks, and most look the same: text-heavy, generic, and forgettable. What you need is a clear structure, polished design, and the flexibility to make quick updates.

This investor pitch deck template gives you exactly that. It includes the slides investors expect—business overview, market opportunity, financial projections, ROI, and exit strategy—so you can focus on refining your story instead of wrestling with design.

What makes this powerful

• Fully editable in Flipsnack’s Design Studio for quick updates and easy customization
• Embed demo videos, testimonials, or interactive elements to keep investors engaged
• Track who viewed your deck, how long they spent, and what caught their attention
• Save and reuse the deck for future funding rounds, ensuring consistency and saving time

With this template, you’re not just sending another pitch, you’re sharing a compelling, interactive story that investors will actually remember.

2. Editable business partnership proposal template

Forming a partnership is about more than numbers—it’s about trust, alignment, and showing that you understand each other’s goals. A messy or unclear proposal can slow down negotiations and create doubts before the real conversation even starts.

This editable business partnership proposal template helps you present your offer with structure and credibility. It gives you ready-made sections for outlining goals, responsibilities, and revenue-sharing terms, so you can focus on the partnership details instead of formatting.

What makes it indispensable:

• This template supports embedded videos, captioned highlights, link buttons, and contact forms, to capture attention and gather feedback.
• You can update your proposal anytime and keep the same link active, so everyone sees the latest version
• Share securely so only the right stakeholders see your proposal

This way, you reduce friction, protect sensitive details, and give partners the clarity they need to move forward confidently.

3. Interactive nonprofit proposal template

As a nonprofit, you’re constantly balancing two needs: sharing your mission in a way that moves people emotionally while also proving your impact with clear numbers. Grant reviewers and donors want to feel connected to your cause, but they also need to trust that funds will be used responsibly. A static, text-heavy proposal rarely achieves both.

This interactive nonprofit proposal template helps you strike that balance. It gives you ready-made sections for your mission statement, program descriptions, impact metrics, budget breakdowns, and long-term sustainability plan. You can focus on telling your story, while the structure ensures your proposal looks professional and credible.

Ways to bring your proposal to life:

• Embed testimonial videos, founder interviews, or stories from the field to build emotional connection
• Use infographics, donor stats, or interactive maps to make your impact easy to grasp
• Send trackable links for grant applications, campaigns, or donor outreach to see how different audiences engage

4. Interactive startup proposal template

As a founder, you don’t have time to waste. You’re juggling product development, team building, and investor outreach, and every pitch feels like it could change your company’s future. The last thing you need is to spend hours formatting slides or worrying if your deck looks professional enough.

This interactive startup proposal template helps you cut through that stress. It’s built so you can focus on telling your story with clarity and energy, while still covering the details investors care about most. Instead of sending bulky attachments that get lost in inboxes, you share a secure, interactive proposal that’s easy to open, easy to follow, and hard to forget.

What makes it indispensable:

• Covers all essentials: company overview, market analysis, product breakdowns, financial forecasts, and funding requirements. 
• Includes built-in interactivity and branding elements to make your proposal instantly recognizable
• Features actionable CTAs like embedded contact forms and video buttons, helping you turn interest into real conversations faster

5. Editable business plan proposal template

When you’re building a business plan, the pressure is real, you need to look professional, cover all the essentials, and avoid wasting time on formatting. This editable business plan proposal template takes that weight off your shoulders. With ready-made sections for everything from your executive summary to financial plan, it gives you the structure you need so you can focus on telling your story with confidence.

What makes this powerful:

• Interactive elements like embedded videos, GIFs, branded visuals, and clickable buttons elevate the reading experience.
• Secure sharing options allow controlled access to confidential plans via password protection or SSO.
• Easily customizable in our Design Studio, so you can adjust content or make updates anytime without starting over

6. Interactive event proposal template

When you’re pitching an event, you’re not just selling logistics, you’re selling an experience. Sponsors and clients want to see the vision come to life before they commit, and a static PDF rarely does that.

This interactive event proposal template helps you transform ideas into a clear, compelling plan that feels real and engaging. With structured sections for everything from objectives to budgets, it lets you show what the event will look and feel like, building confidence from the start.

Why this template stands out:

• Includes embedded virtual tours that offer stakeholders a clear sense of the event atmosphere and venue potential.
• Built-in contact forms make it easy for sponsors or clients to respond right away, speeding up decisions.
• A polished layout builds trust and reassures stakeholders that every detail is handled professionally.

How to build your own proposal using Flipsnack

Templates are only the beginning. Flipsnack offers flexible ways to build persuasive, interactive business proposals tailored to your goals and audience.

1. Upload a PDF or PowerPoint and turn it into an interactive proposal

If you’ve already built a proposal in another tool, there’s no need to start over. Simply upload your PDF or PowerPoint into Flipsnack, and within seconds it transforms into a shareable, interactive flipbook. You can add and customize interactive elements, all without touching the original design. And once you hit share, you’ll be able to track exactly how recipients engage with your proposal.

Use this option when:

• You’re refreshing older pitch decks or investment briefs
• You want to preserve layout but increase engagement 
• You are on a tight deadline and need a polished, professional proposal fast
• You want to track who views and engages with your proposal
• You want a secure sharing method that lets you update content while keeping the same link

2. Start from a blank canvas or proposal template using Flipsnack’s Design Studio

If you want complete control over structure and design, Flipsnack’s Design Studio gives you the freedom to build proposals your way. Start with a blank page or customize any of the templates we’ve covered above to match your brand, message, and audience. The result is a proposal that feels uniquely yours, without the need for advanced design skills.

Best for when you:

• Need a fully tailored proposal for a specific client, sponsor, or opportunity
• Want control over every detail: fonts, spacing, sections, layout
• Must maintain strict brand consistency across all proposals  
• Are building reusable proposal frameworks for future outreach

3. Customize your proposal with interactivity

Static proposals are easy to skim and forget. To really hold someone’s attention, your proposal needs to feel dynamic, more like a compelling story. With Flipsnack, you can add interactive elements that not only make your proposal look polished but also guide your audience through the key points you want them to notice.

What you can add:

• Videos to showcase your product in action or deliver a personal message that text can’t capture.
• Slideshows to present case studies, project timelines, or market data without overwhelming a single page.
• Embedded forms for collecting feedback or capturing interest on the spot.
• Clickable CTAs and link buttons that direct readers to your website, pricing models, or other assets
• Pop-ups or captions to add context, answer FAQs, or legal disclaimers, without breaking visual flow

Whether you’re pitching a new partnership, proposing a nonprofit initiative, or presenting a business expansion plan, these interactive elements help your audience stay engaged, retain information, and act faster.

4. Share publicly or privately, on your terms

Once your proposal is polished and ready, Flipsnack gives you full control over how it’s shared.

Public sharing options:

• Generate a direct link, or a QR code you can send immediately
• Embed the document on your website or intranet
• Publish as part of a public-facing proposal library 

Private sharing options: 

• Email directly to select recipients with personalized messages
• Restrict access with a password-protected link
• Enable one-time passcode delivery for sensitive business proposals
• Use SSO to ensure only verified users can access the document

5. Track how your proposals perform

Sending a proposal is only half the job. Knowing how it was received is what gives you an edge. With Flipsnack’s built-in analytics, you can see exactly how recipients interact with your proposal, so you’re never left guessing what worked and what didn’t.

Here’s what you can learn:

• Views and impressions: Know who opened your proposal and how many times it’s been reviewed
• Clicks on interactive elements: See which videos, buttons, or links actually sparked interest
• Time spent per page: Identify which sections captured attention and which ones were skimmed
• Devices used: Understand whether your audience reads on desktop, mobile, or tablet to optimize the experience

This visibility helps you act with confidence. If an investor lingered on your financials, you’ll know to prepare deeper insights. If a partner opened but didn’t respond, you’ll know it’s time to follow up. With data guiding your outreach, every proposal becomes a chance to refine your message and increase your success rate.

Beyond templates: how Flipsnack helps you create, enhance, share, and track impactful proposals

Templates are just the starting point. What really makes a proposal resonate is how well it’s tailored to the person on the other side. Do your research, understand what they value, and adapt your proposal to your audience so it feels personal and relevant, not generic—because the best proposals don’t just present ideas, they connect with people.

Flipsnack gives you the platform to make that possible at every stage. You can create and manage professional documents, enhance them with interactive elements that keep attention, share them securely on your terms, and track engagement to see what truly resonates. Every phase is designed to help you refine your message and deliver proposals that are polished, personal, and persuasive.

When you combine personalization with the right tools, your proposals become more than documents—they become strategic assets that build trust, inspire action, and drive growth. With Flipsnack, you have everything you need to communicate with confidence and impact.
