Most comparison articles treat proposal software and estimation tools as separate categories. For a software development agency or IT software agency, that distinction doesn’t make sense.
You don’t need a tool that just generates a pretty PDF. You don’t need a tool that just spits out a cost range. You need a tool that takes a client brief, turns it into a structured estimate, presents it as an interactive proposal, and carries through to delivery — all while protecting your margin.
This guide compares tools that serve the specific needs of software agencies and IT software agencys. Not construction firms. Not solo freelancers testing an idea. Not grant writers. Agencies that send proposals, estimate projects, and need to win deals profitably.
What Separates Agency-Grade Tools from General Proposal Software
Most proposal tools (PandaDoc, Qwilr, Proposify, etc.) were built for sales teams sending product quotes. They make documents look good. They handle e-signatures. They track opens.
What they don’t do: estimate projects. A software agency can’t just paste a price into a template. They need to break down scope, assign hours to roles, account for complexity, and justify the numbers. A generic proposal tool gives you fonts and layouts but zero estimation capability.

Tool Comparison
Apropo — Best for Agencies That Need to Win AND Protect Margin
What it does: Apropo is built specifically for software agencies and IT software agencys. It combines AI-powered estimation with interactive web-based proposals — so you go from client brief to signed deal in one workflow, not three separate tools.
Key capabilities:
- AI scope generation: Upload a client brief, PDF, or Word document → Apropo’s AI produces a structured breakdown: modules, tasks, role assignments, hour ranges (optimistic/pessimistic), and assumptions.
- Interactive web proposals: When the client opens an Apropo proposal, they can toggle scope items on and off. The price and timeline change in real time. They can leave comments on specific line items.
- Client behavioral insights: See exactly which sections the client spent time on — including mouse movement recordings. Know what they cared about before the follow-up call.
- WBS component library: Build a reusable library of modules, tasks, and hour estimates from past projects. Every estimate gets more accurate and faster.
- Export flexibility: Branded PDF, Excel (for internal planning), and a web link (for instant sharing).
- Delivery integration: Export to Jira, Linear, or Asana — the estimate becomes actionable tasks.
- Margin protection: Built-in change request workflow. When scope changes, the price updates automatically.
- Excel import: Upload existing Excel sheets → Apropo structures them into reusable components.
Best for: Software agencies, dev shops, and IT software agencys sending 5+ proposals per month.
Free trial: 14 days
Case studies: 100+ agencies including Pagepro (3.5x faster estimates), Profil Software (1.8x conversion), White Label Coders (20% margin increase).
PandaDoc — Best for Document Workflow & E-Signature
What it does: PandaDoc is a mature document automation platform. It excels at creating, sending, and signing documents. Its AI capabilities have improved, but it remains a document tool first — not an estimation tool.
Why agencies might use it: Strong CRM integrations (Salesforce, HubSpot), built-in e-signature, payment collection, approval workflows.
Where it falls short for agencies: No project estimation. No role-based scope breakdown. No interactive pricing. You’d need to calculate your estimate externally (spreadsheet or another tool) and then paste the numbers into PandaDoc. That’s two tools for one job.
Best for: Teams that already have an estimation process and just need document workflow + e-signature.
Pricing: From $35/user/month.
Qwilr — Best for Interactive Web Proposals (Presentation Layer)
What it does: Qwilr turns proposals into responsive web pages. Strong design, good brand control, dynamic pricing tables with conditional logic, real-time analytics on client engagement.
Why agencies might use it: The interactive web format is genuinely better than static PDFs. Clients can click through sections, and the agency sees what was viewed.
Where it falls short for agencies: No estimation engine. Qwilr makes proposals look great, but it doesn’t help you figure out what to charge. You still need to estimate scope separately and manually enter the numbers. No role-based estimation, no hour ranges, no margin tracking.
Best for: Agencies that have their estimation process locked down and want a better presentation layer.
Pricing: From $39/user/month.
Proposify — Best for Proposal Analytics & Pipeline Management
What it does: Proposify focuses on the management layer — analytics, approval workflows, role-based permissions, content library.
Why agencies might use it: Strong pipeline-level analytics. If you’re sending many proposals and want to track win rates by template, team member, or deal size, Proposify gives you that data.
Where it falls short for agencies: Like PandaDoc and Qwilr, Proposify is a document platform. No estimation. No scope generation. No interactive pricing. The analytics are about the proposal document, not about the project it describes.
Best for: Sales managers who want proposal pipeline analytics and already have an estimation workflow.
Pricing: From $29/month.
Cobl — Best for AI-Generated Proposals from CRM Context
What it does: Cobl connects to your CRM, emails, and notes to generate proposal drafts that reflect the actual deal context. Strong AI agents for layout, brand consistency, and proofreading. GDPR-compliant, EU servers.
Why agencies might use it: If you have rich CRM data, Cobl can produce personalized draft proposals quickly.
Where it falls short for agencies: No estimation engine. No project scope breakdown. No role-based hours. Like the others, it handles the document side but not the estimation side. Also no built-in e-signature.
Best for: Agencies with mature CRM data who want AI-assisted proposal drafting.
Pricing: Free tier (3 docs/month), then paid.
CostGPT — Best for Quick Cost Ballparks
What it does: Enter a project description → get a rough cost range. Fast, simple, no setup.
Why agencies might use it: Useful for the “should we even pursue this?” conversation. Quick sanity check before investing time in a detailed estimate.
Where it falls short: No detailed scope breakdown, no role assignments, no proposals, no export options beyond a number. Fine for a ballpark, insufficient for an actual client proposal.
Best for: Quick cost ranges before committing to a full estimate.
Pricing: Limited free tier.
How to Choose the Right Tool for Your Agency
| Your Situation | Recommended Approach |
|---|---|
| You need estimation + proposals in one workflow | Apropo — built for this exact use case |

| You have estimation figured out, want interactive web proposals | Qwilr + your existing estimation process |
| You need fast structured internal estimates for your dev team | devtimate (then manually build a proposal) |
| You need a quick cost range before deciding to pursue a project | CostGPT |
The Reality: Most Agencies Use 2-3 Tools When They Should Use One
Here’s the uncomfortable truth we hear from agencies regularly:
“We estimate in a spreadsheet, then copy the numbers into a Word doc, then convert to PDF, then send it. When the client asks ‘what if we remove X?’, we go back to the spreadsheet.”
This workflow costs hours per proposal and creates inconsistency. Every time numbers are copied manually, mistakes happen. Every time the client asks a “what if” question, there’s a delay while someone recalculates.
The tools that solve 100% of this problem are rare — because most tools started on one side (proposal document OR estimation engine) and never crossed over.
Apropo was built specifically to cross that gap. One tool from brief → estimate → interactive proposal → signature → delivery.
What to Look For in an Agency-Grade Tool
Based on our analysis of what actually drives results for agencies, here are the criteria that matter:
- End-to-end workflow: Does the tool handle estimation AND proposals, or do you need a second tool?
- Interactive client experience: Can the client explore scope and pricing on their own, or do they get a static document?
- Reusable knowledge base: Does the tool learn from past estimates, or does every project start from zero?
- Margin visibility: Can you see exactly where your profit is — and what happens when scope changes?
- Delivery handoff: Does the estimate flow into your project management tool, or does it die in a PDF?
FAQ
What’s the difference between proposal software and estimation software?
Proposal software helps you create, send, and track documents. Estimation software helps you figure out what to charge. For a software agency, you need both — and ideally in one tool. Using separate tools means copying numbers between them, which wastes time and introduces errors.
Can a single tool really handle both estimation and proposals?
Yes, but only a few tools are built for it. Apropo was designed from the ground up for this combined workflow. Most tools in the market started as either document platforms (PandaDoc, Qwilr) or estimation engines (devtimate, CostGPT) and never integrated the other side.
Do agencies really use Excel for estimates?
Yes. Despite the rise of AI tools, a significant number of agencies still estimate in Excel. It’s familiar, flexible, and already integrated into their workflow. A tool that can import existing Excel sheets (instead of forcing a migration) dramatically reduces switching costs.1
How do interactive proposals help agencies win deals?
Interactive proposals let clients explore scope and pricing on their own terms. Instead of sending a static PDF and waiting for questions, the client can toggle features, see the price impact, and understand trade-offs in real time. This reduces follow-up calls and builds trust through transparency.2
What integrations matter most for agencies?
Jira, Linear, and Asana are the most requested — because the estimate needs to become actionable tasks. CRM integration (HubSpot, Salesforce) is secondary for most agencies. Check that your chosen tool exports to your project management platform before committing.
How quickly can an agency get value from an AI estimation tool?
Most tools offer a 14-day free trial. The first estimate takes the longest (1-2 hours to set up your component library), but by the third estimate, most agencies report significant time savings.
Is Apropo only for large agencies, or can small teams use it too?
Apropo is used by agencies of all sizes — from 3-person dev shops to 100-person software agencys. The free trial lets you test it without commitment. The key variable is how many proposals you send per month, not your team size.
The Bottom Line
If you’re a software agency or IT software agency, you have two options:
Option 1: Use separate tools for estimation and proposals. Estimate in devtimate or a spreadsheet → copy numbers into PandaDoc, Qwilr, or Proposify → manage the gap manually. This works, but it costs hours per proposal and creates margin-blind spots.
Option 2: Use a tool built for the full pipeline. Apropo generates the estimate, turns it into an interactive proposal, lets the client explore pricing in real time, and feeds into delivery. One workflow. One source of truth.
The choice depends on whether you see proposals as a necessary evil or a competitive advantage.
