How we evaluated proposal writing software

We looked at each proposal writing tool from the point of view of a UK SME with a small team and no dedicated bid department. That means five criteria: how fast you get from blank page to a credible first draft, whether the tool understands the kind of document you actually send (a sales quote is not a Selection Questionnaire), whether pricing is published and affordable, how well it reuses your existing content, and whether it handles the compliance side of the job.

  • Drafting: templates, content libraries and AI generation from your own material.
  • Fit: sales proposals, RFP questionnaires or UK public-sector tenders.
  • Cost: published pricing and whether a small team can justify it.
  • Workflow: approvals, collaboration, exports to Word or PDF, e-signature.
  • Data handling: where content is stored and whether it trains shared models.

Ratings are our editorial judgement against those criteria, not averages from review sites. Pricing was taken from vendor websites where published; where it is not, we say so.

How to choose the best proposal software

How to choose proposal software
  1. 1

    Name the document

    Sales quote, RFP questionnaire or UK public tender. The answer rules out half the market.

  2. 2

    Count your volume

    A handful of bids a year suits a flat subscription; hundreds suits a library-led platform.

  3. 3

    Check where content comes from

    The best tools draft from your own case studies and policies, not generic text.

  4. 4

    Test on a live document

    Run a real proposal or tender through the free plan or trial before you commit.

  5. 5

    Check data handling

    Ask where content is stored and whether it trains shared models.

Types of proposal software

Proposal software is a broad label, and the nine tools in this list fall into three distinct groups. Knowing which group you need saves time on demos.

TypeWhat it is forTools in this listTypical user
Sales proposal and document toolsDesigning branded quotes and proposals, e-signatures and paymentsProposify, PandaDoc, Qwilr, Better ProposalsAgencies, consultancies and B2B sales teams
RFP response platformsAnswer libraries, AI drafting and workflow for questionnairesLoopio, ResponsiveMid-size and enterprise sales and bid teams
AI bid and tender writingDrafting scored, word-limited answers to tender questionsAutogenAI, AI Tender Writer and sector-specific tender toolsBid teams and SMEs answering public tenders

UK tender tools also find opportunities, which sales proposal tools do not.

Proposal software vs tender writing software

Sales proposal software assumes you are responding to a warm lead: you choose the structure, add pricing tables, send a link and track when the client opens it. That works well for private-sector deals. It does little for a UK public-sector tender, where the buyer publishes fixed questions and scoring criteria, you upload answers to a portal, and your proposal is marked by an evaluation panel against published descriptors. Features such as open tracking and e-signatures are irrelevant there, while word-limit control, criteria-based drafting and social value support matter a great deal.

Many businesses need both. A facilities company might use PandaDoc or Proposify for private client quotes and a tender tool for council and NHS contracts. If most of your revenue comes from public contracts, start with the tender tool; if most comes from private clients, start with a sales proposal tool and add tender support when you begin bidding for public work.

Must-have features in proposal writing software

  • Content reuse: a library of approved sections, case studies and team bios that you can drop in and update in one place.
  • AI drafting grounded in your content: answers generated from your own documents, not generic text, so you can stand behind every claim.
  • Templates and brand control: consistent layouts and styles for sales proposals.
  • Pricing tables and approvals: for sales proposals, configurable pricing with internal sign-off before sending.
  • Word and PDF export: essential for tenders, where you upload to the buyer's portal or template.
  • Collaboration: comments, assignments and version history when several people contribute.
  • Integrations: CRM connections such as HubSpot or Salesforce for sales teams.

Writing a better proposal, whatever software you use

  1. Start with the client's problem in their words, not your company history.
  2. State your recommended solution and its main benefit in the first paragraph.
  3. Explain how you will deliver: people, steps, timescales and how progress will be reported.
  4. Prove it with two or three specific results from similar work.
  5. Make pricing clear and show what is included, so the client can compare like with like.
  6. In tenders, follow the buyer's question order and word limits exactly, and answer every sub-question.
  7. Close with next steps and a named contact.

Common mistakes when choosing proposal software

  • Choosing on design features when your real bottleneck is writing the content.
  • Buying a sales proposal tool to answer public tenders, then finding it cannot handle portal questions or word limits.
  • Paying per user for people who only contribute occasionally; check whether reviewers need full seats.
  • Skipping the content set-up. Templates and libraries only save time once they hold your best, current material.
  • Not testing on a real document. A trial on a live proposal or tender tells you more than any demo.

Proposal software for small businesses

Small businesses rarely need an enterprise platform. If you send a few sales proposals a month, a document tool with good templates and e-signatures, such as Proposify, Better Proposals, Qwilr or PandaDoc, will pay for itself in saved formatting time. If you bid for public contracts, the bigger time cost is writing scored answers and finding the right tenders, so look at the tender-focused tools in this list, several of which have free plans. Either way, pick one tool, load your best content and use it on your next live proposal before adding anything else.

How AI is changing proposal writing

Most proposal platforms now include generative AI to draft sections, summarise requirements or rewrite text in a different tone. The quality of the output depends on the content you give the tool, and every draft needs review by someone who knows the client and the work. For UK public-sector bids, PPN 017 means buyers may ask whether AI was used, so choose a tool that drafts from your own evidence and keep a record of who reviewed each answer.

Buyer's guide: proposal writing tools for UK public-sector work

Sales proposal software assumes you control the format. Public-sector tenders do not work that way. Buyers set the questions, word limits and weightings, and you usually answer inside their e-tendering portal or their Word template. Since 24 February 2025 most UK public procurement runs under the Procurement Act 2023, with notices published on the Find a Tender service and supplier details held on the Central Digital Platform.

  • Look for question-by-question drafting, not only document design.
  • Check the tool respects word limits and the buyer's scoring criteria.
  • Social value now carries a minimum 10% weighting in central government procurements under PPN 002.
  • PPN 017 asks suppliers to be ready to disclose AI use in bids, so pick a tool that drafts from your own evidence you can stand behind.
  • Export to Word matters, because most buyers still ask for uploads.

FAQs

Frequently asked questions

What is proposal software?
Proposal software helps you build, send and track proposals. Most tools combine templates, a content library, pricing tables and e-signatures. Newer tools add AI drafting from your own content.
What is the best proposal software?
For private-sector sales proposals, Proposify is our top pick. For UK public-sector tenders, look at a tool that finds tenders and drafts answers question by question, such as those ranked second and third in this list.
Is there free proposal writing software?
Several tools offer free trials. Some UK tender tools, including AI Tender Writer, have free plans with one AI scan a month and no card required.
Can proposal software write tenders?
Sales proposal tools can hold tender content but are not built for questionnaire-style public tenders. Tender-specific tools draft answers question by question against the buyer's criteria and word limits.
How much does proposal software cost?
Published prices range from around $19 per user per month for entry sales proposal plans to flat subscriptions such as £149 a month for AI Tender Writer Pro. Enterprise RFP platforms usually quote on request.
Should I tell a buyer I used AI to write my proposal?
PPN 017 lets public buyers ask about AI use in bids. Use tools that draft from your own evidence, review every answer, and be ready to disclose AI use if asked.
What is the difference between proposal software and RFP software?
Proposal software usually creates and sends sales proposals with design, pricing and e-signature features. RFP software focuses on answering buyer questionnaires from a content library. Tender tools such as AI Tender Writer focus on scored UK public-sector questions.
Can I use proposal software for government tenders?
You can use it to draft content, but most sales proposal tools do not handle portal submissions, word limits or evaluation criteria. A UK tender tool is usually a better fit for public-sector bids.
Is there free proposal software?
Several tools offer free trials, and some UK tender tools offer free plans with limited AI scans. Check each vendor's site for current terms, as trial lengths and free tiers change.
How do I choose between Proposify, PandaDoc and Qwilr?
All three create and send sales proposals. Compare them on templates, pricing tables, CRM integrations, e-signature and per-user cost, and run a real proposal through each free trial before deciding.
Does proposal software help with social value answers?
Sales proposal tools generally do not. UK tender tools such as AI Tender Writer include a social value generator aligned to the TOMs framework, which helps with the minimum 10% weighting in in-scope central government contracts under PPN 002.
