7 Best Proposal Software Tools for Marketing Agencies 

For a marketing agency, a proposal is much more than just a price quote; it’s your first deliverable. It showcases your design capabilities, attention to detail, and ability to communicate value effectively.

Unfortunately, many agencies are still using outdated methods for proposal creation. They spend hours struggling with layout in InDesign or Word, exporting a static PDF, attaching it to an email, and then… waiting for a response. This leads to what we call the “Black Hole” of sales: you have no idea whether the client opened the document, which sections they read, or whether they forwarded it to their boss.

Modern proposal software completely transforms this process. By adopting cloud-based proposal tools, marketing agencies can reduce proposal creation time by 50%, track client engagement in real time, and secure e-signatures. Here are the seven best proposal software tools for marketing agencies in 2025.

What Marketing Agencies Should Look for in Proposal Software

Before we get into the details, it’s important to clarify what makes a tool “agency-ready.” While a basic document signer may work for a plumber, marketing agencies have specific needs:

1. Visual Customization: Since you are selling branding and aesthetics, your proposal software must support custom fonts, high-resolution images, and embedded videos. It should look as professional and polished as your website.

2. Engagement Tracking: You need to know when a client opens the proposal and how long they spend on the pricing page. This information is crucial for determining the best time to follow up.

3. Ease of Use: If the software has a steep learning curve, your team will be reluctant to use it. The aim is to send proposals in minutes, not hours.

4. Integrations: The software should seamlessly integrate with your CRM (like HubSpot or Pipedrive) and your accounting software (such as QuickBooks, Xero, or Stripe) to automate invoicing once a proposal is signed.

5. Pricing: As agencies grow, they shouldn’t face excessive fees for adding new team members. The pricing structure should accommodate scaling without penalizing expansion.

– 14-day free trial available (no credit card required).

Cons:

– Currently focuses only on proposals and quotes, rather than full project management.

Best For: Small to mid-sized marketing agencies and digital consultancies seeking the best return on investment.

2. PandaDoc 

PandaDoc is a leading player in the document automation industry. It is a powerful tool designed to manage complex workflows, including contracts, quotes, and HR documents.

Pros:

– Robust CRM Integrations: PandaDoc offers excellent integrations with platforms like Salesforce and Microsoft Dynamics.

– Workflow Approval: It is ideal for large agencies that require proposals to be approved by a Sales Director before sending them to clients.

– Security: The tool complies with enterprise-grade security standards (SOC 2 Type II).

Cons

– Corporate Feel- The templates and interface can feel rigid and business-oriented, lacking the creative touch that many boutique agencies prefer.

– Cost- Access to integrations (such as Salesforce) and custom branding requires a higher-tier Business or Enterprise plan, which can become expensive quickly.

Best For- Large agencies (50+ employees) with dedicated sales teams and complex legal approval processes.

3. Qwilr 

Qwilr takes a unique approach by treating proposals as “microsites” rather than traditional documents. When you send a Qwilr proposal, you are providing a link to a responsive webpage.

Pros

– Wow Factor- You can embed features like ROI calculators, Google Maps, and full-screen video backgrounds directly into the proposal.

– Interactive Pricing- Clients can “shop” within the proposal by selecting checkboxes for add-on services, with the price updating automatically.

Cons

– PDF Issues- Since the proposals are web pages, exporting them to PDF for clients who require a hard copy often leads to formatting issues.

– Learning Curve- Designing a webpage differs from writing a document, and it may take time to learn how to use the layout tools effectively.

Best For- Web design and creative agencies that want to showcase their technical skills.

4. Proposify 

Proposify is often compared to Adobe InDesign in the cloud, offering a robust platform that provides detailed control over typography, layout, and snippet management.

Pros

– Design Freedom- If your agency prioritizes pixel-perfect layouts and strict brand guidelines, Proposify offers exceptional control.

– Content Library- It is excellent for storing snippets of text (such as case studies or team bios) that can be easily dragged and dropped into new proposals.

Cons

– Clunky Interface- The editor can be slow to load and may occasionally have bugs due to the complexity of its design features.

– Overkill for Many- For numerous agencies, the complexity of Proposify can hinder the sales process instead of speeding it up.

Best For- Design-led agencies where the Creative Director demands strict adherence to brand guidelines.

5. Better Proposals 

Better Proposals truly lives up to its name by providing a significant upgrade over traditional Word documents, focusing on speed and simplicity.

Pros

– Speed- The interface is streamlined, enabling you to create and send proposals very quickly.

– Payment Integration- It offers good integrations with payment gateways like PayPal, Stripe, and GoCardless.

Cons

– Limited Customization- The block-based builder restricts your ability to move elements around freely, unlike platforms such as Prospero or Proposify.

Best For- Freelancers and agencies that prioritize the speed of sending proposals over complex design customization.

6. HoneyBook

HoneyBook is more than just a proposal tool; it’s a comprehensive Client Relationship Management (CRM) suite that manages everything from the initial inquiry form to the final invoice.

Pros

– Lifecycle Management- You can oversee your calendar, contracts, and payments all from a single dashboard.

– Automation- It’s excellent for setting up automatic email triggers, such as sending a thank-you email two days after signing.

Cons

– Jack of All Trades- While it covers many functions, its specific proposal features are quite basic. The design options are limited compared with dedicated tools such as Prospero.

– Ecosystem Lock-in- HoneyBook works best if you transition your entire business process to its platform.

Best For- Solo marketers and boutique agencies looking for an all-in-one operational platform.

7. Canva 

We included Canva because many agencies already use it for creating social media graphics. While it is possible to design proposals in Canva, there are some limitations to consider.

Pros

– Infinite Design Options- You have access to millions of stock photos, graphics, and fonts.

– Familiarity: Your team is likely already familiar with how to use the platform.

Cons

– The “Dumb Document” Problem- Canva exports are typically in PDF format or as view-only links. It lacks features like native e-signatures and analytics. Consequently, you cannot see if the client has opened the document, and they cannot sign it legally without exporting it to a third-party tool, which adds friction to the process.

Best For Pitch decks that are presented live during a Zoom call, rather than proposals that need to be signed.

Why Free Proposal Tools Are Costing You Money

You might be tempted to stick with Microsoft Word, Google Docs, or InDesign to avoid a monthly subscription fee. However, this can often be a case of being “penny wise, pound foolish.”

The Mobile Experience

More than 40% of proposals are opened on mobile devices. Viewing a PDF on a phone often requires “pinch and zoom,” which creates a frustrating user experience and makes your agency appear outdated. Modern software like Prospero is responsive, automatically adjusting text to fit the screen size.

The Follow-Up Guessing Game

Without analytics, you can’t determine the right time to follow up. If you contact a client who hasn’t yet opened your email, you may come across as desperate. Conversely, if you call them just five minutes after they have read the pricing section, you appear proactive.

Friction Kills Deals

Asking a client to print, sign, scan, and then email a document back introduces unnecessary delays and gives them time to reconsider. Using e-signatures can reduce turnaround time by 40%.

Conclusion

Your proposal is the crucial link between a potential lead and a paying client. If this link is hard to navigate due to poor mobile formatting, complicated printing requirements, or unclear content, you risk losing revenue.

For marketing agencies in 2025, automation has become a necessity rather than a luxury.

If you need a tool that delivers enterprise-level capabilities without the enterprise-level cost or steep learning curve, Prospero is the perfect solution. It enables you to create impressive, trackable proposals that capture clients’ attention and get signed more quickly.
