Frequently asked questions

PDF Sign is an online e-signature platform for Indian businesses. You upload a PDF (or start from a ready-made agreement), add the people who need to sign, and send. Each signer verifies their identity with a one-time code, signs from any device, and everyone receives a digitally sealed PDF with a certificate of completion and a tamper-evident audit trail.

Usually two to three minutes. Upload the PDF, type the signers’ names and emails, and PDF Sign places signature, name and date fields automatically where the document has signature lines. Check the placement, adjust anything by dragging, and press Send.

No. Signers receive a personal link by email, enter a one-time code sent to their email or phone, and sign in the browser on a phone, tablet or computer. There is nothing to install and no password to create.

Yes. The Free plan lets you send three agreements a month with full evidence: verified signers, sealed PDF, certificate of completion and audit trail. No card is required. Paid plans add more agreements, team members, SMS verification, branding, bulk send and the API.

Any PDF up to 25 MB: offer letters, NDAs, MoUs, vendor agreements, project contracts, consent forms, rental and leave-and-licence agreements, purchase orders and more. You can also generate 16 professionally drafted business agreements from the template library.

Yes, for most commercial documents. The Information Technology Act, 2000 gives legal recognition to electronic records (Section 4) and to contracts formed through electronic means (Section 10A), and the Indian Contract Act, 1872 does not require most contracts to be signed on paper. Some documents are excluded by the First Schedule of the IT Act, including negotiable instruments other than cheques, powers of attorney, trust deeds, wills, and contracts for the sale or conveyance of immovable property. Where a specific law requires a signature in a prescribed form, use a notified electronic signature such as a DSC or Aadhaar eSign.

Every agreement on PDF Sign produces evidence: the identity check each signer passed, their consent to sign electronically, an explicit confirmation of intent, IP address and device, SHA-256 fingerprints of the original and final PDF, a PAdES digital seal, and RFC 3161 trusted timestamps, all recorded in a hash-chained audit trail and summarised in a certificate of completion. The evidence package can be downloaded as a single ZIP file.

Stamp duty depends on the type of instrument and the State, not on how it is signed. If an agreement attracts stamp duty, pay it (for example through e-stamping on SHCIL) and attach the e-stamp certificate as the first page of the PDF before sending it for signature. Some agreements, such as leave and licence agreements in Maharashtra, must also be registered.

No. PDF Sign provides secure electronic signatures with strong identity verification and evidence, which suit the vast majority of commercial agreements. Aadhaar eSign and Digital Signature Certificates are specific forms of electronic signature notified under the IT Act and are required only where a law specifically demands them, such as some government filings.

No. The template library contains careful drafts based on Indian law and common practice, but every business is different. Have a lawyer review agreements that matter to you, especially before using them at scale.

Documents are stored privately and can only be opened by authorised users or by signers after verifying a one-time code, through short-lived links. Data is encrypted in transit and at rest. Passwords are hashed with Argon2id, and teams can enforce authenticator-app two-factor sign-in.

Not without it being detected. The final PDF carries a PAdES digital seal that PDF readers check, its SHA-256 fingerprint is recorded, and the audit trail is append-only and hash-chained, so any edit to the file or the history breaks verification.

Use the free verification page. Drop the PDF there: it is hashed in your browser and never uploaded, and the page confirms whether it matches a sealed agreement, when it was completed and how many people signed, without revealing names or content.

Only your organization’s authorised users and the people you send them to. Platform staff cannot open your documents in normal operation; emergency access requires a written reason, expires after 30 minutes and is recorded in your agreement’s audit trail, which you can see.

Yes. Add as many signers as you need. They can sign at the same time, or one after another in the order you choose. You can also add approvers, witnesses and people who only receive a copy.

PDF Sign reads the text of your PDF and looks for signature lines and labels such as “Signature”, “Name”, “Date” and “Designation”. It groups them into one signature block per party and assigns them to your signers in order. If it cannot find a spot for someone, it adds a signature block at the end of the document for you to drag into place.

Yes. Add text fields assigned to the client, or use the Project Contract template, which includes a client details section (legal name, address, GSTIN, PAN and contact). The client completes it while signing, so you only need their name and email to send.

They can decline with a reason. Everyone involved is notified, the agreement is marked as declined, and the reason is recorded in the audit trail. You can correct the document and resend it in one click.

Yes. Choose how often reminders go out when you send. Signers also receive a warning before an agreement expires, and you can send a reminder manually at any time.

There is a Free plan, and paid plans are priced in rupees per user per month, with a discount for yearly billing. Prices exclude GST. See the pricing section for the current plans.

Payments are processed by Razorpay using UPI, cards or net banking. A GST tax invoice is generated automatically for every payment and emailed to your billing contact, with CGST and SGST or IGST shown according to your State.

Yes. Cancel from the billing page; paid features stay active until the end of the period you have paid for, and you can keep using the Free plan afterwards. Your completed agreements remain available.

Yes. Invite colleagues with roles: Owner, Admin, Manager, Sender or Viewer. Senders see only their own agreements, while managers and admins see everything. You can belong to several organizations and switch between them.

Yes. The Business plan includes a REST API with scoped API keys and idempotency keys, plus signed webhooks for events such as agreement sent, signed, completed and declined. The OpenAPI specification and reference are public.

Yes. Bulk send creates a separate agreement for each row of a CSV file from a template, for example offer letters or policy acknowledgements, each with its own audit trail.
