OTP-based e-sign that's legally valid under the IT Act 2000 — and unlike DocuSign or PandaDoc, it doesn't stop at the signature. Your contract flows straight into a GST invoice with a UPI payment link, in the same tool.
Scope, price, and timeline carry over the moment a client accepts — nothing retyped.
They open a link, verify with an OTP sent to their phone, and sign — legally valid under the IT Act 2000, Second Schedule.
Timestamp, IP address, and OTP confirmation are embedded in the signed PDF automatically.
No refreshing your inbox — a push notification the second the contract is complete.
They're great at signatures. None of them get you paid.

Yes. OTP-based electronic signatures are legally valid under the IT Act 2000 (Second Schedule) and admissible as evidence under Section 65B of the Indian Evidence Act, provided the platform maintains a proper audit trail.
DocuSign and PandaDoc are excellent general-purpose e-sign tools, but they're priced in USD, built for enterprise workflows, and stop at the signature — you still have to manually create the invoice and chase payment. ClearWork's e-sign is one step in a connected flow: proposal → contract → GST invoice → UPI payment, all in the same tool.
No. Your client opens a link, verifies their identity with an OTP sent to their phone, and signs — no login, no app download, no account required.
A tamper-evident PDF is generated with the full audit trail (timestamp, IP address, OTP confirmation) embedded, and stored securely — accessible to both you and your client anytime.
Yes — OTP-based signing works for any client with a phone number. If your contract specifies Indian jurisdiction, IT Act 2000 governs regardless of where your client is based.
