How to e-sign a document in 4 steps

  1. 1

    Upload your document

    Upload a PDF or Word file: your contract, NDA, invoice or any document that needs e-signing.

  2. 2

    Add signers and fields

    Enter each signer's e-mail and drop signature, date or text fields exactly where they're needed.

  3. 3

    Signers get a secure link

    Each signer receives a secure link by e-mail and signs from any device, with no account required.

  4. 4

    Track and finalize

    Follow progress in real time. The moment everyone signs, you all get the legally binding, AATL-sealed document.

Why your e-signatures hold up?

AATL-certified eSignatures

Every document is signed using the PAdES standard and backed by the Adobe Approved Trust List — recognized signing technology, not just an image on a page.

Legally binding electronic signature

Valid under ESIGN/UETA in the US, eIDAS across all EU member states, and UK law — with a verifiable audit trail on every document.

Tamper-proof & ISO 27001

Every signed document is sealed with a digital certificate and a full audit trail — once signed, it can't be altered.

Affordable, free to start

A genuinely free plan for occasional use, then plans from just $5/user/month — a fraction of what the big names charge.
