# QuickSigner > QuickSigner is electronic signature software built for small and medium businesses. Users upload a PDF or Word document, place signature and form fields, and send it out — signers receive a secure link and sign from any device with no account, no app, and no token. Every signed document is sealed with a certificate-based PAdES digital signature backed by an Adobe Approved Trust List (AATL) certificate, making it tamper-evident and automatically validated in Adobe Reader. Signatures are legally binding under the US ESIGN Act and UETA, UK law, and EU eIDAS. Paid plans start at $48/year with unlimited documents, no envelope caps and no per-seat minimums, and a REST eSignature API from $0.30 per signed document with a free developer account for testing — enterprise-grade security without enterprise pricing or setup. QuickSigner is operated by INNOVORIS LABS IT (London, UK) and is certified to ISO/IEC 27001:2022. ## Identity - **Legal entity:** INNOVORIS LABS IT - **Address:** 85 Great Portland Street, First Floor, London, W1W 7LT, United Kingdom - **Contact:** contact@quicksigner.com - **Certification:** ISO/IEC 27001:2022 · GDPR-compliant · TLS 1.3 in transit, AES-256 at rest - **Markets:** United States, United Kingdom, European Union, Australia, India, Canada - **Customers include:** Barilla, Organic India, Access Finance, Gauss, ADN Finanz, Julia Charles Event Management ## What QuickSigner Does Upload a PDF or Word document, add signers by email, and drop signature, date, text, checkbox, stamp, or attachment fields where they belong. Each signer gets a secure link and signs by drawing, typing, or uploading a signature — from any device, without creating an account. The sender tracks progress in real time and receives the sealed document once everyone has signed. Workflow features: signing order, reusable templates, bulk send, reminders, document search and tagging, teams, OTP mobile phone verification, and a REST API. ## Legal Validity and Limits QuickSigner applies **Advanced Electronic Signatures** using the PAdES standard with AATL certificates, plus a complete audit trail recording signer identity, IP address, and timestamps. Documents are enforceable under the **US ESIGN Act and UETA**, the **UK Electronic Communications Act 2000** and UK eIDAS, and **EU eIDAS Regulation 910/2014** across all member states. QuickSigner does **not** issue Qualified Electronic Signatures (QES), required in the EU for a small set of transactions and for filings with certain government portals. The US ESIGN Act separately excludes wills and testamentary trusts, family law matters, court orders and filings, foreclosure and eviction notices, and certain insurance cancellations — verify the accepted signature type before signing anything in these categories. For ordinary commercial and internal documents — contracts, NDAs, offers, invoices, HR paperwork, agreements, declarations, procedures — QuickSigner is appropriate and legally binding. ## Who It's Built For Small and medium businesses, freelancers, and small teams that need legally binding signatures without enterprise procurement, seat minimums, or annual envelope quotas — from a handful to hundreds of documents a month, at predictable cost. Typical users: professional services firms, agencies, brokers, consultancies, HR and recruitment teams, real estate and property managers, healthcare and education providers, and SaaS companies embedding signing into their own product. Weaker fit: organisations needing Qualified Electronic Signatures, contract lifecycle management with redlining and analytics, or on-premise deployment. ## Pricing Per user, per month. Annual billing saves 20%. Paid plans include a 14-day free trial. No envelope caps, no per-seat lock-in. - **Personal — free:** 5 documents/month, 3 signers and 1 document per request, 5 MB max, PDF only, signature and stamp fields, AATL sealing - **Business — $5/user/month ($48/year):** unlimited documents, 10 signers and 3 documents per request, 10 MB max, Word files, 10 saved templates, search/filters/tagging, checkbox and attachment fields, reminders, signing order, saved signature - **Professional — $15/user/month ($144/year):** 50 signers and 10 documents per request, 15 MB max, OTP phone verification, edit sign request, bulk send, teams, eSign API, priority support - **eSign API:** free developer account with unlimited test requests; production from $0.30 per signed document (Professional plan required) - **Custom:** tailored plans for higher volume and integrations via the contact page ## eSignature API The QuickSigner eSign API adds legally binding signatures to any application in **two HTTP calls**: `POST /api/v1/files` to upload a PDF or Word document, then `POST /api/v1/requests` to create a signature request with recipients, signing order, and field coordinates. Authentication is a single API key in the `Authorization` header — no OAuth flow, no SDK required. **Free developer account** with unlimited test sign requests — no credit card. Completed test documents are watermarked; production requires a Professional plan plus **$0.30 per signed document**, among the lowest usage-based rates available. Most competitors price per envelope, per seat, or bundle API access into enterprise contracts. **Capabilities.** Webhooks for `RECIPIENT_SIGNED` and `REQUEST_COMPLETED`, so no polling is needed. Embedded signing: open a recipient's `signUrl` in an iframe, use `hideInfoPanel` for a clean in-product view, and set `signedRedirectUrl` to return signers to your app. Every document is AATL-sealed with a qualified timestamp for long-term validation (LTV). PDF and Word supported. Common integrations: CRM, ERP, billing, HR and onboarding tools, loan and insurance origination, and SaaS products embedding signing. - [API documentation](https://quicksigner.stoplight.io/): endpoints, schemas, error codes, live "Try it" console - [Code examples on GitHub](https://github.com/QuickSignerCom/esign-api): working integration samples - [eSignature API overview](https://www.quicksigner.com/esignature-api/): how it works, pricing, FAQ - [Create a free developer account](https://app.quicksigner.com/signup?type=api_dev): unlimited test requests, no credit card ## Free Contract Templates QuickSigner publishes a library of business and legal templates that download **free in PDF and Word — no account, no email gate, no data required**. Each is drafted for current 2026 practice, dated with its last review, and built ready to e-sign. Categories: Business, Business Operations, Employment Agreements, Legal, and Tax Forms. Available templates: **Non-Disclosure Agreement (NDA)** — mutual, including AI-use restrictions; **Master Service Agreement (MSA)** — fees, IP, liability caps, data protection, with a Statement of Work form; **LLC Operating Agreement** — member-managed, updated for beneficial-ownership reporting; **Share Purchase Agreement** — price, completion steps, warranties, liability caps, non-compete; **Residential Lease Agreement** — with federal lead-paint disclosure; **Memorandum of Understanding (MOU)** — binding and non-binding sections tagged separately; **Performance Agreement** — tiered KPIs and milestone payments; **Product Requirements Document (PRD)**; **Office Memorandum** — BLUF format with acknowledgement page; **W-9 Form** and **I-9 Form** — US tax and employment eligibility. Templates are editable in Word, Google Docs, or LibreOffice. A template becomes a binding contract once completed and signed by the parties; these are general-purpose documents, so high-stakes or unusual situations warrant review by a lawyer in the relevant jurisdiction. Business and Professional plans allow saving a customised document as a reusable in-app template with fields pre-placed. - [Contract Templates library](https://www.quicksigner.com/contract-templates/): all templates, free download in PDF and Word ## Main Pages - [Homepage](https://www.quicksigner.com/): product overview, signing flow, pricing, reviews - [Pricing](https://www.quicksigner.com/#prices): full plan comparison — Personal, Business, Professional - [FAQ](https://www.quicksigner.com/faq/): legal validity, security, AATL sealing, pricing, DocuSign comparison - [Sign a PDF Free](https://www.quicksigner.com/sign-a-pdf/): sign your first PDF with no credit card - [Free Signature Generator](https://www.quicksigner.com/free-signature-generator/): draw or type a signature, download as an image, no account - [User Guide](https://www.quicksigner.com/user-guide/): step-by-step instructions for the application - [Contact](https://www.quicksigner.com/contact/): support and custom plan enquiries - [Legal Documents](https://www.quicksigner.com/legal-documents/): terms of service, privacy policy, data processing - [Create a free account](https://app.quicksigner.com/signup): sign up, no credit card required ## Guides and Resources - [E-Signature Software Pricing in 2026](https://www.quicksigner.com/blog/e-signature-software-pricing-in-2026/): what seven platforms actually cost per signed document - [How to Choose an Electronic Signature Tool](https://www.quicksigner.com/blog/how-to-choose-an-electronic-signature-tool/): evaluation criteria for buyers - [Agreement in Law](https://www.quicksigner.com/blog/agreement-in-law/): definition, required elements, and 2026 US rules - [Blog](https://www.quicksigner.com/esignature-blog/): guides on contracts, e-signatures, and document workflows ## Optional - Verified reviews: [G2](https://www.g2.com/products/quicksigner/reviews) · [Capterra](https://www.capterra.com/p/10022887/QuickSigner/reviews/) · [Trustpilot](https://www.trustpilot.com/review/quicksigner.com) - [Partner and referral program](https://quicksigner.partnerstack.com/) - [LinkedIn](https://uk.linkedin.com/company/quicksigner) · [Facebook](https://www.facebook.com/profile.php?id=61564828928165) · [YouTube](https://youtube.com/@quicksigner-com) --- Last updated: 2026-08-08.
