Why QuickSigner

Everything you switched to e‑signatures for. None of the enterprise overhead.

One price, unlimited documents

$5 per user per month on the Business plan, with no envelope caps, no annual lock-in and no quote to request. Every price is published below.

Zero friction for the signer

Recipients open a link and sign in the browser, on a phone, tablet or laptop, in under a minute. No account, no app, no token.

Signatures that hold up in court

Every PDF is PAdES-sealed with an Adobe-trusted certificate and timestamp. Behind it sits a log of every event: each opening, IP, device, consent, field signed and notification delivered.

How it works

From upload to sealed PDF, without the back-and-forth.

Four steps, shown in the real QuickSigner app (Professional plan) and API, exactly as your team and your signers will see them.

Step 1 · Send

Send in under a minute

Upload a PDF or Word file, add your signers and set the signing order. Place signature, date, text, initials, checkbox or stamp fields exactly where they belong, assign each one to a signer and press Send.

  • Up to 10 signers and 3 documents per sign request (50 and 10 on Professional)
  • Signing order, or everyone at once
  • Reusable templates for the contracts you send every week
Send your first document free
app.quicksigner.com/requests/new

Step 2 · Sign

Signers need nothing

Your signer opens the e-mail link and goes straight to the document. They draw, type or upload a signature, the date fills itself, and one tap completes it. No account, no app, no PDF reader.

  • Draw, type or upload a signature
  • Each signer sees only their own fields
  • In signing order, the next person is notified as soon as the previous one has signed

Step 3 · Track

Track every step, prove every signature

Every request shows who has opened it, who has signed and when, and you can nudge a signer with a one-click reminder. When the last signature lands, download the sealed PDF and its certificate with the complete event log: enough to rebuild a signing minute by minute for a judge or an investigator.

  • Status, timestamps and request ID at a glance
  • Each opening, IP, device, consent, field signed and notification delivered, logged
  • Search, filters and tags across every document you have sent

Step 4 · Automate

Automate it with the eSignature API

Two REST calls: upload the PDF, then create the sign request. QuickSigner returns a signing URL for each recipient, to e-mail or embed in your own product, and calls your webhook as signatures come in. Developers build and test for free. In production the API runs on the Professional plan, where your first 50 sign requests are free and each one after costs $0.30, negotiable for volume.

  • Create requests from a PDF or from a saved template
  • Webhooks when a recipient signs and when the request is completed
  • Free developer account with unlimited test requests

How to eSign documents and collect eSignatures with QuickSigner
Watch the tour · 1:30
Mobile & identity

Send and sign from any device. Know who signed.

QuickSigner runs in the browser: your team can place fields and send from a phone, and signers tap the link and sign on any device, with nothing to install. When identity matters, turn on OTP verification by SMS: the document opens only after the signer enters a one-time code sent to their phone.

  • Android, iPhone, iPad or laptop, in any browser
  • One-time SMS code before the document opens (Professional plan)
  • The code, the phone number and the time are written to the event log

Customer reviews

Teams that switched, in their own words.

★★★★★
For a small team of 5–6 people, QuickSigner has replaced DocuSign completely. We’re able to track who is sending what documents, and can have preset templates for them to use. Overall, really solid platform, that just works!
Alexandr WangTrustpilot
★★★★★
Probably among the best electronic signature platforms. The signatures are legally binding and Adobe-certified (PAdES compliant, ISO 27001), and the pricing is far more affordable than the bigger legacy platforms.
Andrew F.Capterra
★★★★★
This service is a true hidden gem. After researching affordable e-signature tools, this is hands down the best one I found. It’s affordable, practical, and reliable, which is hard to find in this space.

The guide

Everything you need to know about electronic signature software

What is an electronic signature software?

An electronic signature web software lets people sign documents digitally — so contracts, agreements, and forms get signed from anywhere, on any computer or mobile device.

Every document is protected by encryption and a complete event log, and electronic signatures are legally valid and enforceable for most business documents in most countries, including under the U.S. ESIGN Act and the EU’s eIDAS regulation. And when you’re ready to automate, the QuickSigner eSignature API lets you embed the same legally valid signatures directly into your own product.

What is an electronic signature?

Under U.S. federal law, an electronic signature is any electronic sound, symbol, or process attached to or logically associated with a record and executed with the intent to sign it. Every QuickSigner e-signature is a certificate-based digital signature, built on PAdES technology and Adobe Approved Trust List (AATL) certificates. That means cryptographic proof of who signed, tamper-evident protection of the document, and automatic validation when opened in Adobe.

Operational efficiency

Get agreements signed in minutes, not days. Upload your PDF or Word document, add signers, and send — no printing, scanning, or chasing signatures. QuickSigner is ISO/IEC 27001:2022 certified and its e-signatures are legally binding and AATL-certified, so even the smallest team gets enterprise-grade signing without the enterprise price tag or setup. Less paperwork, faster deals, more time to run your business.

Alternative to DocuSign

Everything you switched to e-signatures for — without the envelope caps. DocuSign’s Standard and Business Pro plans cap sending at roughly 100 envelopes per user per year, with overage fees beyond that. QuickSigner delivers legally binding, AATL-certified signatures with unlimited documents on every paid plan: free to start, unlimited plans from $48/year, and an e-Sign API from $0.30 per sign request. No per-seat lock-in, no surprise invoices.

Still doing envelope math? We tested 6 DocuSign alternatives side by side — see how they compare.

eSignature API

Add legally binding e-signatures to your own app or workflow with the QuickSigner REST API. Create sign requests from documents or templates, embed signing in your product, and get a webhook the moment a document is completed. Every signed PDF is PAdES-sealed with an AATL certificate and a trusted timestamp, so it validates in Adobe Reader. Testing is free with a developer account, and production costs $0.30 per sign request, with volume discounts available above 500 sign requests a month.

Contract templates

Send the same document twice? Make it a template. Turn any contract, NDA, or form you use regularly into a reusable template — with signature, date, and text fields already placed, and recipient roles ready to fill in. Next time, you skip the setup entirely: pick the template, add the signer’s email, and send. What took ten minutes of dragging fields now takes thirty seconds, and every agreement goes out consistent, complete, and error-free.

Mobile experience

Sign and send from any device — Android, iPhone, iPad, or laptop. QuickSigner runs in the browser, so there’s nothing to install: your signers just tap the link and sign, whether they’re at a desk or in the field. Same full features, same security, every screen size. Business doesn’t pause when you step away from your desk.

Privacy and security

Your documents are protected at every stage. QuickSigner is ISO/IEC 27001:2022 certified and GDPR compliant, and encrypts your data with TLS 1.3 in transit and AES-256 at rest. Role-based access controls ensure only authorized people can view each document, and a complete event log records every action — from upload to archive.
