For most agencies, the proposal is where good leads go quiet. The discovery call goes well, the team promises a proposal by Friday, and then someone spends six hours copying last month's document, rewriting the scope, rebuilding the pricing table and exporting a PDF that the client opens once and forwards to a colleague without context. Proposal software, and now AI proposal tools, exist to cut that time and to turn the proposal into something a client can read, approve, sign and pay in one place. This guide compares the tools agencies actually use, and shows how to automate the steps around them.
In short. PandaDoc is the best all-round choice for most agencies, with strong templates, native e-signature and payments, AI drafting and wide CRM integrations. Proposify is the most agency-focused, with approval workflows and content governance for growing teams. Qwilr is the pick for creative and design agencies that want interactive, web-based proposals. Better Proposals and Nusii are the most affordable for small agencies. RFP platforms such as Loopio only make sense if you answer formal RFPs every month.
What an Agency Actually Needs From Proposal Software
Agencies have different needs from enterprise sales teams. Before you compare features, check these:
- Reusable building blocks: case studies, team bios, service descriptions and terms you assemble rather than rewrite.
- Pricing that clients can adjust: optional services, packages and retainers the client can select, with totals that update.
- Fast drafting: AI that turns discovery notes into a first draft of the scope and objectives, in your voice.
- A client experience that sells: a proposal that looks like your agency, works on mobile and shows you when and how it was read.
- Signature and payment in the same place: so the deposit lands the day the client says yes.
- CRM sync: the proposal created from the deal, and the deal updated when the proposal is viewed, signed or paid.
- Approvals for larger teams: discounts and custom terms checked before the proposal leaves.

The Comparison Table
| Tool | Creation and AI | Client experience | Agency workflow | Cost for 5 users | PURIST Fit Score |
|---|---|---|---|---|---|
| PandaDoc | 8/10 | 9/10 | 8/10 | 7/10 | 8.0/10 |
| Proposify | 7/10 | 8/10 | 9/10 | 6/10 | 7.5/10 |
| Qwilr | 7/10 | 9/10 | 7/10 | 7/10 | 7.5/10 |
| Better Proposals | 6/10 | 8/10 | 7/10 | 9/10 | 7.5/10 |
| Nusii | 5/10 | 7/10 | 7/10 | 9/10 | 7.0/10 |
| Loopio (RFP platform) | 9/10 | 5/10 | 6/10 | 3/10 | 5.8/10 |
Three tools tie behind PandaDoc, for different reasons: Proposify on workflow, Qwilr on client experience and Better Proposals on price. The right one depends on what usually loses you deals: slow internal approvals, proposals that do not stand out, or a budget that cannot carry per-seat tools. Loopio scores low here only because it is built for RFP and security questionnaire teams, not for agency proposals.
The Real Cost Comparison Nobody Publishes
Published prices change often and third-party roundups disagree, sometimes because they quote different plan generations. The figures below are reported ranges; check each pricing page before you buy.
| Tool | Reported pricing | Notes |
|---|---|---|
| PandaDoc | Paid plans reported from roughly $19 to $35 per user per month, with Business around $49 to $65 per user | E-signature and payments on paid plans; CRM integrations stronger on higher tiers |
| Proposify | Build plan reported around $35 per user per month billed annually; Grow reported around $325 a month with five seats | Approval workflows and content governance on the team plan |
| Qwilr | Business reported around $35 per user per month, Enterprise around $59 | Proposals are interactive web pages rather than PDFs |
| Better Proposals | Starter reported around $19 a month, Premium around $29, Enterprise around $49 | Lowest entry price in most roundups; some AI features on higher plans |
| Nusii | Agency plan reported around $41 to $49 a month, including several users | Built specifically for agencies and freelancers |
| Loopio | Custom, with procurement data reporting a median above $20,000 a year | For RFP teams, not agency proposals |
Per-seat pricing adds up quickly. For a five-person agency, flat or team-based plans (Nusii, Proposify Grow, Better Proposals) can cost less than per-seat tools once everyone who writes or approves proposals needs access.
Tool by Tool
PandaDoc
PandaDoc is the most complete general-purpose option: a large template library, a content library for reusable sections, interactive pricing tables, AI assistance for writing, legally binding e-signature and payment collection, and integrations with HubSpot, Salesforce, Pipedrive and many other tools. Agencies use it for proposals, contracts and statements of work in one system. Its breadth is its strength; the trade-off is that the best workflow and integration features sit on higher tiers. If e-signature is your main concern, our DocuSign vs PandaDoc vs Dropbox Sign comparison goes deeper.
Proposify
Proposify is built around the proposal process for growing teams. Its strengths are content governance (locked sections so nobody edits the legal terms), approval workflows before sending, interactive pricing with optional items, and analytics on how clients read the document. It is one of the most frequently recommended tools for marketing agencies specifically. Reviews describe its AI features as lighter than some competitors, so test drafting on a real proposal during the trial.
Qwilr
Qwilr turns proposals into interactive web pages instead of documents. Embedded videos, case studies, live pricing the client can configure, and acceptance with payment on the page make it especially strong for creative, design and branding agencies, where the proposal itself is judged as a piece of work. It also provides engagement analytics so you know when the decision-maker is reading.
Better Proposals
Better Proposals focuses on ease of use and price. It offers templates, e-signature, payment integrations and tracking at the lowest entry price in most comparisons, which makes it a strong choice for small agencies and freelancers who send a handful of proposals a month and want them to look professional without a learning curve.
Nusii
Nusii is designed for agencies and freelancers, with a simple editor, reusable sections, client approval and integrations with common CRMs and payment tools. Its agency plan includes several users at a flat price in recent roundups, which makes it one of the most affordable multi-user options. It is less feature-rich than PandaDoc or Proposify, which is exactly why some small teams prefer it.
Loopio and RFP platforms
Loopio, AutoRFP.ai and similar AI tools are built to answer long RFPs and security questionnaires from a governed content library. They are powerful and expensive. If your agency wins work through public tenders or enterprise procurement and answers RFPs every month, they can pay for themselves. For pitch proposals to small and mid-sized clients, they are overkill.
Which Tool Fits Which Agency
- A growing marketing or digital agency with a sales process and a CRM: PandaDoc, or Proposify if approvals and content control are the priority.
- A creative, design or branding agency where the proposal is part of the pitch: Qwilr.
- A small agency or freelancer sending a few proposals a month: Better Proposals or Nusii.
- An agency winning work through formal RFPs: a proposal tool for pitches plus Loopio or another RFP platform for tenders.
How to Automate the Whole Proposal Flow
The biggest time savings come from connecting the proposal tool to everything around it. A typical flow we build with n8n for agencies looks like this:
- 1 Deal reaches the proposal stage in the CRM. The workflow pulls the client, contact, budget and discovery notes.
- 2 AI drafts the scope. Claude turns the discovery notes into objectives, scope, timeline and assumptions in your agency's voice, using your past proposals as reference. A person reviews and edits.
- 3 The proposal is created from the right template, with pricing filled from your service catalog and the case studies that match the client's industry.
- 4 Approval if needed: discounts above a threshold or custom terms go to a partner for sign-off.
- 5 Tracking and follow-up: when the client opens the proposal, the account owner is notified; if it is not opened within a few days, a follow-up is scheduled.
- 6 Signed and paid: the CRM deal is marked won, the deposit invoice is recorded, the project is created in your project management tool and the kickoff email goes out.
The result is that a proposal goes out the same day as the discovery call, and the handover to delivery happens without anyone retyping the scope. Our document generation automation guide covers the template and data side in more detail, and our proposal builder shows the structure we recommend.
Frequently Asked Questions
What is the best AI proposal software for agencies?
PandaDoc is the best all-round choice for most agencies. Proposify is the most agency-focused for teams that need approvals and content control, Qwilr is best for creative agencies that want interactive web proposals, and Better Proposals and Nusii are the most affordable for small teams.
Can AI write a full agency proposal?
AI can produce a strong first draft of the objectives, scope, timeline and assumptions from discovery notes and past proposals. Pricing, final scope and anything contractual should still be reviewed by a person before the proposal is sent.
How much does proposal software cost for an agency?
Reported prices range from about $19 a month for entry plans to roughly $35 to $65 per user per month for business tiers. Team plans such as Proposify Grow or Nusii's agency plan can be cheaper for five users than per-seat pricing.
Is PandaDoc or Proposify better for agencies?
PandaDoc is better if you want one tool for proposals, contracts, e-signature and payments with broad CRM integrations. Proposify is better if your priority is a controlled proposal process for a growing team, with approvals and locked content.
What is AI proposal automation?
AI proposal automation connects your CRM, an AI model and your proposal tool so that proposals are drafted, assembled, approved, tracked and handed over to delivery automatically, with people reviewing the content rather than building documents from scratch.
