What açai Sign Does
Built for the whole
signing lifecycle.
From the moment you upload a document to the day your auditor asks for the trail, every step is handled with intelligence, care, and court-ready compliance.
Reusable templates
Turn your offer letter, NDA, or vendor agreement into a one-minute send. Merge fields auto-populate per recipient.
Bulk send via CSV
Upload a CSV of recipients and dispatch hundreds of personalised contracts in a single action - each with its own merge values.
In-app document editor
Make last-minute edits to a Word file without leaving the app. Smart field placement controls font, size, and alignment.
Tamper-evident sealed PDFs
Every completed envelope ships with a full chain-of-custody audit: who signed, when, from where, on what device.
Full envelope lifecycle
Reminders, expiry alerts, decline + void flows, resend invites, duplicate envelopes, sub-folders, Inbox & Outbox views, reports.
Six steps, signed and sealed.
From the first upload to the audit-ready final PDF, every envelope moves through a workflow that's fast, secure, and legally defensible.
Step 1 of 6 · Upload
Drop a PDF or Word file — done.
Start an envelope in seconds. Upload from your desktop, paste from a URL, or pull from the açai document library. Word files can be edited in-app before sending.

Step 2 of 6 · Place
Smart field placement, anywhere on the page.
Drop signatures, initials, dates, and data fields exactly where they belong. Control font, size, and alignment so the final stamp looks native to the document.
Step 3 of 6 · Send
One signer, a hundred, or a whole CSV.
Single send, sequential signing, or bulk dispatch from a CSV — every recipient gets a personalised envelope with merge fields filled in automatically.
Step 4 of 6 · Sign
OTP-protected access, on any device.
Signers verify via OTP, then sign with a signature pad, library upload, or saved signature. Sign-yourself flow works for self-attested documents too.
Step 5 of 6 · Track
Reminders, expiry alerts, void & resend.
Stay on top of every envelope. Automatic reminders, expiry alerts, decline + void flows, resend invites, duplicate envelopes — all from the Outbox.
Step 6 of 6 · Seal
Tamper-evident PDF + court-ready audit.
Every completed envelope ships sealed with a chain-of-custody audit: who signed, when, from where, on what device — independently verifiable via RFC 3161 timestamps.
Built on the standards your auditor already trusts.
Aadhaar eSign
UIDAI-backed signing for any Indian citizen via Aadhaar + OTP. IT Act 2000 §3A compliant out of the box.
eMudhra DSC
Class 2 / Class 3 Digital Signature Certificates for high-value contracts, board resolutions, and MCA / GST / Income-Tax filings.
DigiLocker
Push completed contracts straight to the signer's DigiLocker so they always have a verified, government-issued copy.
GeM (Government e-Marketplace)
Vendor-side signing for tender responses on India's largest public procurement platform.
RFC 3161 Timestamps
Every sealed PDF carries a trusted third-party timestamp so signature time is independently verifiable in court.
Open API + Webhooks
Drop Sign into your existing HRIS, ERP, CRM, or vendor portal in a day. Event webhooks fire the instant a document completes.
Aadhaar eSign, eMudhra DSC, and DigiLocker are wired in for India. ESIGN Act + UETA (US), eIDAS-aligned signature tiers (EU & UK), and Singapore / Australia / UAE compliance are on the rolling roadmap — region-aware signing surfaces switch the right framework based on the recipient's jurisdiction.
