Document generation software fills a template with data, from a CRM, a spreadsheet, a form or an API, to produce finished documents such as quotes, contracts and invoices. The right tool depends on where your data lives: CRM-native tools for Salesforce, standalone tools like PandaDoc for sales teams, and APIs like Docmosis for developers.
Checked 3 October 2026 against each vendor’s own pricing page, documentation, Salesforce AppExchange listing, GitHub licence file or press release. Prices are US list prices unless marked in euros. Three tools on our earlier version of this page, Google Workspace, Adobe Acrobat Sign and pdfFiller, are not document generation software; they are explained below.
| If you need to | Our pick | From (vendor price) | Priced by |
|---|---|---|---|
| Send sales quotes and proposals | PandaDoc | $19 a user a month billed annually; $49 with CRM integrations | User |
| Generate high volumes from Zapier, Make or other apps | Docupilot | $29 a month for 100 documents | Documents |
| Turn form submissions into documents | Formstack Documents | $250 a month (Suite), billed annually | Plan |
| Stay 100% inside Salesforce | S-Docs | Quote only | Quote |
| Run complex Salesforce document packages | Conga Composer | Quote only | Quote |
| Cover a whole Salesforce org at a flat price | Nintex DocGen | $5,000 a year for up to 100 users | Company |
| Generate documents from monday.com or HubSpot | DocuGen | Free (watermarked); $25 a month | Documents |
| Assemble legal documents in Word | Pathagoras | $379 one-time | Licence |
| Call an API from your own software | Docmosis | $49 a month for 4,000 pages | Pages |
| Self-host a free engine | Carbone | Free; Cloud from €29 a month | Documents |
What is document generation software?
Document generation software produces documents automatically by merging data into a template. You design a template once, in Word, a web editor or an HTML file, with placeholders for names, prices, dates and tables; the software fills them from a record and outputs a DOCX or PDF. One template can then produce thousands of tailored quotes, contracts, invoices, letters or reports without retyping.
Tools differ mainly in where the data comes from:
| Type | Where the data comes from | Examples on this page |
|---|---|---|
| Standalone (web app) | Its own records, CRM integrations, forms, Zapier or Make | PandaDoc, Docupilot, Formstack Documents |
| CRM-native | Records inside Salesforce (or monday.com, HubSpot) | S-Docs, Conga Composer, Nintex DocGen, DocuGen |
| Word add-in | Answers typed into Word, clause libraries | Pathagoras, HotDocs |
| Developer API or engine | JSON or XML sent by your own software | Docmosis, Carbone, docxtemplater |
| Built into a suite | SharePoint lists, Sugar records, a spreadsheet | Microsoft 365 content assembly, SugarAI Doc Merge, Word mail merge |
What is not document generation software?
Three products on our earlier version of this page do something else, and search results still mix them in:
- Google Workspace sells no product called document generation. Google Docs has variable chips for reusable templates, available on Business Standard and higher plans but not Business Starter, and AppSheet can fill a Docs template from app data. For a real merge from a sheet you still need a script or a separate tool.
- Adobe Acrobat Sign is e-signature software. Adobe’s document generation lives elsewhere: Document Builder in Acrobat Sign for Salesforce, which Adobe says needs no additional purchase, and the Document Generation API for developers, which includes 500 free document transactions a month. The $12.99 to $23.99 prices our earlier version gave for Acrobat Sign were Acrobat Standard and Pro, Adobe’s PDF editor.
- pdfFiller is a PDF editor with forms and e-signature, from airSlate. It creates reusable fillable templates, but it does not merge records into documents.
How is document generation software priced?
Vendors charge by five different units, which makes headline prices hard to compare. Check which one applies before you shortlist:
| Unit | Who uses it | Watch for |
|---|---|---|
| Per user (seat) | PandaDoc, Proposify | Template limits on entry plans; extra documents bought as credits |
| Per document | Docupilot, DocuGen, Carbone, Microsoft 365 content assembly | What counts as one document (Carbone counts each 1 MB of data) |
| Per page | Docmosis Cloud | Long documents use the quota faster |
| Per company | Nintex DocGen | A flat fee that only pays off with many users |
| One-time licence | Pathagoras, Docmosis self-hosted | Yearly support renewals on top |
A worked example for a team of three that creates 300 documents a month, at list prices on 3 October 2026:
| Option | Cost | Fits 300 documents? |
|---|---|---|
| PandaDoc Starter, 3 users, annual | $57 a month | Yes: unlimited documents, but only 5 templates |
| Docupilot Plus | $99 a month | Yes: 500 documents and 3 seats included |
| DocuGen Standard (monday.com or HubSpot) | $45 a month | Yes: 400 documents |
| Formstack Suite, annual | $250 a month | No: 250 document deliveries included |
| Microsoft 365 content assembly, automated | $45 a month | Yes: $0.15 a document; manual generation is free with a per-user licence |
| Nintex DocGen (Salesforce) | $416.67 a month ($5,000 a year) | Yes, and covers up to 100 users |
Per-document plans get much cheaper with volume: Docupilot costs $0.29 a document on its $29 plan (100 documents) but $0.07 on its $699 plan (10,000).
The 10 best document generation software
Each tool below is genuine template-plus-data document generation, checked on the vendor’s own site on 3 October 2026.
1. PandaDoc: best for sales documents
PandaDoc builds quotes, proposals and contracts from templates, fills them from its CRM integrations and collects e-signatures in the same document. The free plan covers 5 documents a month; paid plans create unlimited documents. CRM integrations, the content library and pricing tables start on Business; CPQ and workflow automation are on Enterprise.
| Plan or detail | PandaDoc |
|---|---|
| Starter | $19 a user a month billed annually, $35 monthly; up to 5 templates |
| Business | $49 a user a month billed annually, $65 monthly; unlimited templates, CRM integrations |
| Enterprise | Quote (per seat or per document) |
| Runs on | Web browser, including Safari on Mac, plus mobile apps |
Also consider: Proposify, proposal software in the same lane, at $19 a user a month on Basic and $41 on Team when billed annually ($29 and $49 monthly); Business starts at $3,900 a year.
2. Docupilot: best per-document pricing
Docupilot generates documents from Word, PDF and web templates, with data from Zapier, Make and other integrations. Every plan includes unlimited templates; you pay for documents delivered. E-signature is an add-on from $1.50 an envelope, falling to $0.75 with volume, and extra seats cost $4 a month.
| Plan or detail | Docupilot |
|---|---|
| Starter | $29 a month: 100 documents, 1 seat |
| Plus | $99 a month: 500 documents, 3 seats |
| Pro | $149 a month: 1,000 documents, 5 seats |
| Enterprise | $699 a month: 10,000 documents, 25 seats |
3. Formstack Documents: best for forms to documents
Formstack Documents merges form submissions and other data into documents. Two things changed since our earlier version: Formstack’s company renamed itself Intellistack in June 2025 (the products keep the Formstack name), and Documents is no longer sold on its own. Document generation now comes in Suite, with Forms and Sign, or in custom Salesforce and Enterprise plans.
| Plan or detail | Formstack Documents |
|---|---|
| Suite | $250 a month billed annually, $299 monthly; 3 builders, 250 document deliveries a month, unlimited e-signatures |
| Salesforce Solutions | Custom pricing |
| Enterprise | Custom pricing |
4. S-Docs: best 100% Salesforce-native
S-Docs generates documents and collects e-signatures entirely inside Salesforce, so the data never leaves the platform; an S-Docs for HubSpot now exists too. It no longer publishes prices. Its pricing page says: we do not offer one-size-fits-all pricing.
| Plan or detail | S-Docs |
|---|---|
| Price | Quote only |
| Runs in | Salesforce (and HubSpot) |
5. Conga Composer: best for complex Salesforce documents
Conga Composer builds multi-document packages from Salesforce data and can be embedded in other CRM and ERP systems. Conga, owned by Thoma Bravo, does not publish Composer’s price. Its AppExchange listing says starting at $6 a user a month, but adds that the connector requires the purchase of the core Conga Composer solution directly from Conga.
| Plan or detail | Conga Composer |
|---|---|
| Price | Quote only for the core product |
| Runs in | Salesforce, or embedded via API |
6. Nintex DocGen: best flat price for a Salesforce org
Nintex DocGen for Salesforce (formerly Nintex Drawloop DocGen) generates documents and document packages from Salesforce records. It is the only Salesforce-native tool here with a published price, on AppExchange: from $5,000 a year for up to 100 users, with a 30-day free trial and nonprofit discounts.
| Plan or detail | Nintex DocGen |
|---|---|
| Price | From $5,000 per company a year, up to 100 users |
| Runs in | Salesforce |
7. DocuGen: best for monday.com and HubSpot
DocuGen, from DocuGen, Inc. of Beaverton, Oregon, generates Word, Excel and PDF documents from monday.com boards, and now HubSpot. Its free plan is generous on paper but limited to watermarked PDFs.
| Plan or detail | DocuGen |
|---|---|
| Free | 400 documents or 80 signature sends a month; PDF with watermark |
| Basic | $25 a month: 200 documents or 40 signature sends |
| Standard | $45 a month: 400 documents or 80 signature sends |
| Enterprise | From $90 a month |
8. Pathagoras: best for legal documents in Word
Pathagoras assembles documents from clause libraries inside Microsoft Word. Our earlier version called it cloud software; Pathagoras describes itself as an add-in to, and works within, Microsoft Word, and needs a PC with Word installed. Its homepage links to a cloud version at pathagoras.mobi, which did not load when we checked.
| Plan or detail | Pathagoras |
|---|---|
| Individual | $379 one-time |
| Extra licence | $250 a seat |
| Network bundle | $799 for 3 users |
| Subscription | $25 a month, or $120 for 6 months |
| Runs on | Windows with Word 2007 or later |
9. Docmosis: best API for developers
Docmosis, an Australian, founder-owned company, generates documents from templates via a cloud API or a self-hosted engine (Tornado, or a Java library) that runs on Linux, Windows or Docker. Cloud plans are priced by pages a month, with no overage charges.
| Plan or detail | Docmosis |
|---|---|
| Cloud, 4,000 pages a month | $49 (1 user), $64 (3 users), $78 (10 users) a month |
| Self-hosted | One-time fee with unlimited documents, from $3,795, plus yearly support |
10. Carbone: best free engine to self-host
Carbone, from CarboneIO SAS in France, generates documents from JSON and Office or LibreOffice templates. Its Community Edition is free to self-host, but it is source-available rather than open source: its licence lets you use it as long as you are not offering it as a hosted document-generation service, and it runs a major version behind the paid edition.
| Plan or detail | Carbone |
|---|---|
| Community (self-hosted) | Free, under the Carbone Community License |
| Cloud Free | €0: 100 documents a month |
| Cloud Essential | €29 a month: 1,000 documents |
| Counting rule | Each 1 MB of injected data counts as one document |

Does SugarCRM have document generation?
Yes. SugarCRM, now renamed SugarAI, includes Doc Merge: it generates DOCX, XLSX, PPTX and PDF documents from Sugar records without leaving Sugar. Its documentation says you must be a licensed Sugar Enterprise, Sell, or Serve user with access to the document modules. Sugar also includes PDF Manager, which comes with quote and invoice templates. Sugar Sell plans run from $59 to $135 a user a month, billed annually, with a 15-user minimum.
FAQs
What is document generation software?
Document generation software fills a template with data to produce finished documents such as quotes, contracts, invoices and letters. The data usually comes from a CRM, a spreadsheet, a form or an API, so one template can produce thousands of tailored documents. It differs from e-signature software, which collects signatures on a finished document, and from PDF editors, which change a document by hand.
What is the best document generation software?
It depends on where your data lives. For sales quotes and contracts, PandaDoc is the strongest all-round choice, from $19 per user a month billed annually, or $49 with CRM integrations. Inside Salesforce, choose a native tool such as S-Docs, Conga Composer or Nintex DocGen. For high volumes through Zapier or Make, Docupilot prices by document. Developers should look at Docmosis or Carbone.
Is there free document generation software?
Yes, within limits. Word mail merge is included with desktop Word on Windows and Mac. Zoho Writer gives 200 free merge credits a month, PandaDoc Free creates 5 documents a month, DocuGen’s free plan for monday.com produces watermarked PDFs, Carbone Cloud’s free plan makes 100 documents a month, and Adobe’s Document Generation API includes 500 free transactions a month.
Is there open-source document generation software?
Yes, for developers. The docxtemplater core is dual licensed MIT or GPLv3, JasperReports Library is LGPL-3.0 and python-docx-template is LGPL-2.1. Carbone’s free Community Edition is source-available under its own Carbone Community License, which bars offering it as a hosted service, so it is not open source in the OSI sense.
Which document generation software works on a Mac?
Browser-based tools such as PandaDoc, Docupilot, Formstack Documents, Conga Composer and Nintex DocGen work on a Mac. Word mail merge runs in Word for Mac, Zoho Writer has a Mac app, and Templafy works on a Mac through Office web add-ins. Pathagoras, HotDocs Author and the Fluent (formerly Windward) designer need Windows.
Is document generation the same as e-signature?
No. Document generation creates the document from a template and data; e-signature collects signatures on it. Many tools now do both, such as PandaDoc, Docupilot with its e-signature add-on and Formstack Suite, but e-signature products such as Adobe Acrobat Sign generate documents only through separate features like Adobe’s Document Builder for Salesforce.
How we checked this page
On 3 October 2026 we read each vendor’s pricing page in a full browser, switching monthly and annual billing where offered, and recorded the billing unit and limits; checked Salesforce AppExchange listings for Conga Composer and Nintex DocGen; read the licence files on GitHub for docxtemplater, JasperReports, python-docx-template and Carbone; read Microsoft’s pay-as-you-go and mail merge documentation, SugarAI’s Doc Merge documentation, Google’s variable chips announcement and Adobe’s Document Builder and Document Generation API pages; and checked ownership through company announcements, including Formstack’s renaming to Intellistack and Mitratech’s purchase of HotDocs. The 2022 to 2024 prices in the captions come from screenshots on this page. We did not request quotes or test the tools.
Conclusion
Start from where your data lives. A sales team that wants quotes and contracts with e-signature should try PandaDoc, whose CRM integrations start on the $49 Business plan; a Salesforce shop should compare S-Docs, Conga Composer and Nintex DocGen, and Nintex is the only one with a published price; a non-developer team generating through Zapier or Make at volume should price Docupilot’s per-document plans; and developers should test Docmosis and Carbone side by side. Before you pay, check the billing unit, because a per-user plan, a per-document plan and a per-page plan can differ several times over for the same workload. For the CRM side, see our guide to CRM for startups and small businesses.
