10 Best E-Signature Software of 2026

1. 1

   Docusign eSignature

   The e-signature product from Docusign, sold in Personal, Standard and Business Pro plans with envelope allowances and 1000+ integrations.

   8.8overall

   The e-signature product from Docusign, sold in Personal, Standard and Business Pro plans with envelope allowances and 1000+ integrations.

   Best forTeams of any size that send contracts every week and want the most widely used e-signature platform with a clear upgrade path to Docusign IAM.

   Adoption data

   1.9 millionDocusign reported in its quarterly report for the period ended July 31, 2026 that over 1.9 million customers and more than a billion users use its platform.

   Docusign (SEC Form 10-Q), Docusign, Inc. Form 10-Q for the quarter ended July 31, 2026 (2026): “over 1.9 million customers and more than a billion users worldwide utilize Docusign to accelerate and simplify the process of doing business”

   Docusign eSignature is the default many legal and sales teams compare everything else against, and its filings back that up: the company reported over 1.9 million customers and more than a billion users as of July 31, 2026, including about 289,000 direct customers. Personal costs $11 a month billed annually and covers 5 envelopes a month for one user. Standard, at $30 per user per month annually, adds shared templates, custom branding, commenting, delegated signing and in-person signing for up to 50 users. Business Pro, at $45, adds bulk send, web forms, payment collection and live field validation. The main weakness for high-volume senders is the allowance: both team plans include 100 envelopes per user per year, so a rep sending three contracts a week would outgrow it. Teams that need more move to Enhanced plans or the IAM platform, which adds no-code workflows and AI contract analysis through sales.

   Strengths

   • +Largest filed customer count in the category, over 1.9 million customers
   • +1000+ integrations listed on the pricing page
   • +Clear path from eSignature to Docusign IAM agreement management

   Limitations

   • −Standard and Business Pro cap sending at 100 envelopes per user per year
   • −Personal plan allows only 5 envelopes a month and a single user
   • −Team plans cost $30 to $45 per user per month annually, above most rivals here

   SummaryDocusign eSignature is the safest pick for teams that want the most widely adopted signing platform and deep integrations. Check your annual envelope volume before choosing Standard.

2. 2

   Adobe Acrobat Sign

   Adobe's e-signature service, built into Acrobat for teams plans and sold as a standalone solution for medium and large businesses.

   8.3overall

   Adobe's e-signature service, built into Acrobat for teams plans and sold as a standalone solution for medium and large businesses.

   Best forOrganizations that already use Acrobat for PDFs and want to request signatures from Acrobat, Microsoft 365, Salesforce or Workday.

   Adoption data

   1 billionAdobe said in its third quarter fiscal 2026 results that it reached 1 billion monthly active users across its creativity and productivity products, a company-wide figure that includes Acrobat.

   Adobe (SEC Form 8-K, Exhibit 99.1), Adobe Reports Record Q3 Results (2026): “Achieves major milestone of 1 billion monthly active users (MAU) across creativity and productivity solutions”

   Adobe sells e-signatures two ways. Small businesses get them inside Acrobat Pro for teams, where Adobe says there are no usage caps on eSignatures, so any licensed user can send as many requests as they need alongside full PDF editing, form creation and the AI Assistant. Medium and large businesses are pointed to Acrobat Sign, the standalone service with unlimited seats, deeper integrations and compliance features. Both let senders route a document to several signers who each get a personal copy, track status in real time and keep a complete audit trail, and both work from Word, Teams, Salesforce and Workday. Adobe reported 1 billion monthly active users across its products in September 2026, which shows reach but does not isolate Acrobat Sign. Pricing is the open question here: the business pricing page loaded its prices by geography and did not show US dollars from our location, and Adobe charges a fee on annual plans cancelled after the trial window.

   Strengths

   • +Unlimited eSignatures on Acrobat for teams plans
   • +Signing sits inside the PDF editor many offices already license
   • +Standalone Acrobat Sign option with unlimited seats for larger organizations

   Limitations

   • −USD prices did not load from our location, so cost is unverified
   • −Annual plans billed monthly carry a cancellation fee after the trial window
   • −Adobe's published user figure covers all products, not e-signature alone

   SummaryAdobe Acrobat Sign is the natural choice for teams that live in Acrobat and want unlimited sending without a second vendor. Confirm the US price and cancellation terms before committing.

3. 3

   Dropbox Sign

   The e-signature product from Dropbox, formerly HelloSign, with unlimited signature requests on every paid plan and a separate API.

   8.2overall

   The e-signature product from Dropbox, formerly HelloSign, with unlimited signature requests on every paid plan and a separate API.

   Best forSmall teams of up to 5 senders that want unlimited signature requests and storage in Dropbox, Google or Microsoft.

   Adoption data

   18.20 millionDropbox reported 18.20 million paying users across all of its products in its quarterly report for the period ended September 30, 2026.

   Dropbox (SEC Form 10-Q), Dropbox, Inc. Form 10-Q for the quarter ended September 30, 2026 (2026): “We’ve built a thriving global business with 18.20 million paying users.”

   Dropbox Sign, the former HelloSign, keeps pricing simple: every paid plan includes unlimited signature requests, so there is no envelope math. Essentials costs $15 a month for one user, or $180 a year, and covers templates, signer attachments, in-person signing, template links, field validation, reminders and a non-editable audit trail. Standard, at $25 per user per month, adds the admin console, team roles, reporting, branding and bulk send for up to 5 users; larger teams move to a custom Premium quote. Developers can buy the API separately from $75 a month for 50 requests billed yearly. Dropbox's latest 10-Q reports 18.20 million paying users and over 700 million registered users across the company, which gives the product a large existing base to sell into, though Dropbox does not break out Sign customers. The 22-language interface and stated SOC 2, ISO 27001 and eIDAS compliance make it a fair fit for small international teams.

   Strengths

   • +Unlimited signature requests on paid plans
   • +SOC 2 Type II, ISO 27001, eIDAS and GDPR compliance stated by the vendor
   • +30-day free trial

   Limitations

   • −No permanent free plan for sending
   • −Self-serve team plans top out at 5 users; larger teams need sales
   • −Dropbox's paying user count covers all products, not Sign alone

   SummaryDropbox Sign is the cleanest unlimited-sending option for small teams. Larger organizations will need a custom Premium quote.

   airSlate SignNow

   An e-signature app from airSlate priced per account with unlimited users, plus a per-invite site license for high volume.

   8.1overall

   An e-signature app from airSlate priced per account with unlimited users, plus a per-invite site license for high volume.

   Best forBudget-conscious teams that want many users on one account and features like bulk send and payments at a low monthly price.

   Adoption data

   430M+airSlate, the company behind SignNow, says its products serve more than 430 million users worldwide, a company-wide figure.

   airSlate, airSlate company homepage (2026): “430M+ users worldwide and growing”

   airSlate SignNow prices by account rather than by seat, and every plan allows unlimited users, which makes it unusually cheap for teams where many people sign but few send. Business costs $8 a month billed annually and covers legally binding signatures, unlimited templates and storage, reminders and mobile apps. Business Premium, at $15, adds bulk send, signing links, payment collection, scheduled sending and team reports. Enterprise, at $30, adds custom branding, SMS delivery, stronger signer authentication, conditional and formula fields, approval workflows and a HubSpot add-on. The trade-off is volume: each plan lists 100 signature invites per year, so frequent senders should look at the Site License at $1.50 per invite, which also brings the full API, SSO and phone support. airSlate says its products have 430 million users and 1.8 million eSigned deals a month, but that covers its whole product family.

   Strengths

   • +Lowest entry price among the established vendors here, $8 a month annually
   • +Unlimited users on every plan rather than per-seat pricing
   • +30-day money-back guarantee

   Limitations

   • −Plans include 100 signature invites per year
   • −Custom branding requires the $30 Enterprise plan
   • −airSlate's 430 million user figure spans all its products

   SummaryairSlate SignNow is the strongest value pick for teams that want bulk send and payments for $15 a month. Heavy senders should price the per-invite Site License.

5. 5

   BoldSign

   An e-signature app and API from Syncfusion with a free plan, low per-user prices and unlimited envelopes on its Business tier.

   8.0overall

   An e-signature app and API from Syncfusion with a free plan, low per-user prices and unlimited envelopes on its Business tier.

   Best forSmall businesses that want the lowest per-user price and teams that want unlimited envelopes without enterprise pricing.

   Adoption data

   50,000+BoldSign says on its homepage that more than 50,000 businesses worldwide use it.

   BoldSign, BoldSign homepage (2026): “Trusted by 50,000+ businesses worldwide”

   BoldSign, built by the developer tools company Syncfusion, undercuts every other vendor here on price. The free Essential plan is more generous than most paid entry tiers elsewhere, with 25 envelopes a month, signer authentication, automatic field detection, reminders, requested attachments, custom branding and an audit trail, although personal email signups are limited to 5 envelopes until business details are verified. Growth costs $5 per user per month billed yearly and adds template sharing, in-person signing, print and upload, and team management, with 50 envelopes per user per month. Business, at $15 per user, removes the envelope cap entirely and adds SSO, custom roles, AI field detection, scheduled send, signing groups, IP restrictions and HIPAA on annual plans. BoldSign says more than 50,000 businesses use it, a vendor figure rather than an audited one. It also sells a separate API for embedded signing, and every plan lists email, chat and phone support.

   Strengths

   • +Lowest verified paid price here, $5 per user per month billed yearly
   • +Free plan includes 25 envelopes a month for business email signups
   • +Email, chat and phone support listed on every plan

   Limitations

   • −Growth caps sending at 50 envelopes per user per month and 10 templates
   • −Free plan drops to 5 envelopes a month for personal email signups until verified
   • −Customer count comes from the vendor's own marketing, not a filing

   SummaryBoldSign is the best value in the category, with unlimited envelopes at $15 per user and a usable free plan. Its adoption figure is smaller and unaudited.

6. 6

   PandaDoc

   A document automation platform for proposals, quotes and contracts with e-signatures, a drag and drop editor and CRM integrations.

   7.9overall

   A document automation platform for proposals, quotes and contracts with e-signatures, a drag and drop editor and CRM integrations.

   Best forSales teams that build proposals and quotes and want signing, tracking and CRM sync in the same document.

   Adoption data

   Tens of thousandsPandaDoc says on its company page that its platform is trusted by tens of thousands of companies; it does not publish an exact count.

   PandaDoc, About PandaDoc (2026): “has become a global platform trusted by tens of thousands of companies”

   PandaDoc is a document builder first and an e-signature tool second, which is why sales teams tend to pick it over pure signing apps. Every plan, including Free, uses the same drag and drop editor with rich media, real-time tracking and notifications, and Free allows 5 documents a month. Starter, at $19 per month billed annually, removes the cap on uploads and e-signatures and adds API access. Business, at $49 per seat annually, is where PandaDoc becomes a sales tool, with custom quotes, CRM integrations, a content library, deal rooms, approval workflows, web forms and bulk send, though several of those consume usage credits. Enterprise adds CPQ, workflow automation and SSO, and teams with many occasional users can ask for per-document pricing with unlimited seats instead. PandaDoc says it is trusted by tens of thousands of companies and reached $100 million in ARR in 2024, but it does not publish an exact customer count.

   Strengths

   • +Free plan with 5 documents a month and real-time tracking
   • +Strongest proposal and quote tooling on this list
   • +Option to pay per document instead of per seat

   Limitations

   • −CRM integrations and approval workflows require Business at $49 per seat
   • −API, bulk send and web forms need usage credits or add-ons
   • −No exact published customer count

   SummaryPandaDoc is the best fit for teams whose contracts start as proposals or quotes. Pure signing teams will pay for tooling they do not use.

7. 7

   Zoho Sign

   Zoho's digital signature app with a free plan, a credit system for SMS and identity checks, and compliance controls for regulated industries.

   7.8overall

   Zoho's digital signature app with a free plan, a credit system for SMS and identity checks, and compliance controls for regulated industries.

   Best forBusinesses already on Zoho apps and regulated teams that need qualified electronic signatures or 21 CFR Part 11 controls.

   Adoption data

   100 million+Zoho says its software, across all products including Zoho Sign, has passed 100 million users.

   Zoho, About Zoho (2026): “Marking the milestone of reaching 100 million+ users”

   Zoho Sign is the most compliance-minded of the low-cost options. The free plan covers one user with 5 envelopes a month, signature workflows, an audit trail and imports from WorkDrive, OneDrive, Google Drive, Dropbox and Box. Standard raises the allowance to 25 envelopes per user per month and adds approval workflows, SMS delivery, identity checks by OTP, government ID or knowledge-based questions, witness signing and AI field detection. Professional removes the envelope limit and adds unlimited templates, branding, signer attachments and reports. Enterprise adds bulk send, SignForms, payment collection, in-person signing, qualified electronic signatures, blockchain timestamping and controls for 21 CFR Part 11 and EU GMP Annex 11, which matters for healthcare and life sciences. Many extras consume Zoho Sign credits, with 50 complimentary credits per user per month on Enterprise. Zoho reports 100 million users company-wide but no Sign-specific count, and the pricing page showed euros rather than US dollars from our location.

   Strengths

   • +Permanent free plan and a 14-day trial with no credit card
   • +Compliance controls for life sciences and qualified electronic signatures
   • +Native ties to other Zoho apps plus Google Drive, OneDrive, Dropbox and Box

   Limitations

   • −USD prices did not load from our location, so cost is unverified
   • −SMS, identity checks and many automations consume paid credits
   • −Zoho's 100 million user figure covers all Zoho products

   SummaryZoho Sign suits Zoho customers and regulated teams that need advanced signature types at a low price. Budget for credits if you rely on SMS or ID checks.

   SignWell

   A simple e-signature app priced per sender, with unlimited documents on paid plans and the API included.

   7.7overall

   A simple e-signature app priced per sender, with unlimited documents on paid plans and the API included.

   Best forFreelancers and small offices that send occasional contracts and want unlimited documents for one or a few senders.

   Adoption data

   80,000+SignWell says it has served more than 80,000 businesses and handled more than 17 million signed documents.

   SignWell, About SignWell (2026): “80,000 + businesses served, so far”

   SignWell keeps e-signatures plain and cheap. The free plan allows one sender, one template and 3 documents a month, and unusually it includes the API, audit trail and tamper-proof seal. Light costs $10 a month billed yearly or $12 monthly for one sender with unlimited documents, 5 templates, template links and bulk send, and extra senders cost $10 each on yearly billing. Business costs $30 a month billed yearly for 3 senders with unlimited templates and custom branding, and Enterprise is a custom quote for high-volume API use and dedicated support. SignWell says SOC 2 Type II, HIPAA and audit trails are included on every paid plan, and new business accounts get a 7-day trial of paid features. It reports more than 80,000 businesses served and more than 17 million documents signed. The trade-off is depth: there is no payment collection or approval routing of the kind Docusign, SignNow or Zoho Sign offer on higher tiers.

   Strengths

   • +Free plan with 3 documents a month and API access
   • +Unlimited documents from $10 a month billed yearly
   • +Human support by email or Zoom on every plan

   Limitations

   • −Light allows only 5 templates per sender
   • −Each extra sender costs $10 to $15 a month
   • −Fewer workflow and payment features than larger vendors

   SummarySignWell is a good low-cost choice for one to three senders who just need unlimited signed documents. Teams with complex routing should look higher on the list.

9. 9

   Box Sign

   Native e-signatures inside Box, with unlimited signature requests included in Box Business plans and above.

   7.6overall

   Native e-signatures inside Box, with unlimited signature requests included in Box Business plans and above.

   Best forOrganizations already paying for Box Business or higher that want e-signatures where their contracts are stored, at no added cost.

   Adoption data

   100,000Box reported in its annual report for the fiscal year ended January 31, 2026 that it had over 100,000 paying organizations across its content platform.

   Box (SEC Form 10-K), Box, Inc. Form 10-K for the fiscal year ended January 31, 2026 (2026): “we had over 100,000 paying organizations, and our solution was offered in 25 languages”

   Box Sign is less a product you buy than a feature you may already own. Box says any Business plan or higher includes unlimited signature requests from the Box web app, with no charge per envelope, transaction or user, so a company already storing contracts in Box can start sending them for signature without a second vendor or contract. Requests can also start from Salesforce, Workday, UiPath, NetSuite, HubSpot and other partner apps, and developers can embed signing through the Box API. Signed files stay under the same security and governance policies as the rest of a company's content, which matters to legal and compliance teams. Box reported over 100,000 paying organizations in its January 2026 10-K, a strong base, though not a count of Sign users. The limits are scope and price visibility: Box Sign lacks the payment collection and form features of dedicated tools, and the Box pricing page showed euros from our location, with a 3-user minimum on Business plans.

   Strengths

   • +Included at no extra cost for Box Business customers
   • +Over 100,000 paying organizations reported in Box's 10-K
   • +Signatures stay in the same governed repository as the contract

   Limitations

   • −Only makes sense if you buy Box for file storage
   • −USD prices did not load from our location; Box Business requires 3 users
   • −Fewer signing-specific features, such as payments or web forms, than dedicated tools

   SummaryBox Sign is the obvious first step for teams already on Box Business, since signatures cost nothing extra. Others should choose a dedicated signing tool.

10. 10

    Signeasy

    An e-signature and contract management app with per-seat plans, unlimited sending on team tiers and a 100-day money-back guarantee.

    7.4overall

    An e-signature and contract management app with per-seat plans, unlimited sending on team tiers and a 100-day money-back guarantee.

    Best forSmall and midsize businesses that want unlimited contract sending with basic AI term extraction and Google or Microsoft integration.

    Adoption data

    48,000+Signeasy says on its homepage that more than 48,000 businesses use it.

    Signeasy, Signeasy homepage (2026): “Trusted by 48,000+ businesses around the world”

    Signeasy sits between simple signing apps and contract management tools. Personal costs $10 per seat per month, $120 billed yearly, and lets one person sign unlimited documents and send 5 contracts a month from the web, mobile apps, Google Workspace or Microsoft apps. Business, at $20 per seat, removes the sending limit and adds shared templates, reminders, an admin dashboard, two-factor login, Google Drive and OneDrive sync and AI extraction of key terms and summaries. Business Pro, at $30, adds roles and permissions, signer attachments, signer 2FA, SharePoint and HubSpot connections, SMS delivery as an add-on and approval workflows. Custom plans for 5 or more seats add SSO, bulk send and FDA 21 CFR Part 11 compliance. Signeasy offers a 100-day money-back guarantee on yearly Personal, Business and Business Pro plans, longer than any trial here. Its published count, 48,000+ businesses, is the smallest on this list and comes from its own site.

    Strengths

    • +100-day money-back guarantee
    • +Unlimited sending from $20 per seat per month
    • +Works from Google Workspace and Microsoft apps

    Limitations

    • −Personal plan allows only 5 sent contracts a month
    • −No permanent free plan
    • −Smallest published customer count on this list

    SummarySigneasy is a fair pick for small teams that want unlimited sending and light contract management for $20 per seat. Larger buyers will find more adoption and depth higher up.
