Offer Letter Signing: E-Sign and Send Offer Letters Online

Yes. An offer letter can be signed electronically, and it is legally binding in the United States under the ESIGN Act of 2000 and state UETA laws, as long as the candidate consents to sign electronically and the document keeps an audit trail. Nearly every employment document, offer letters, employment agreements, NDAs, and policy acknowledgments, can be legally signed online.

For the signature to hold up, the candidate has to intend to sign, the signature has to be tied to that specific offer, and the platform has to record a verifiable trail of who signed and when. SignSend captures all three on every offer, which gives HR far stronger proof of acceptance than a scanned signature on a PDF.

The main reason is time to accept. An offer that used to take days of mailing and scanning now gets signed in hours, which matters most when a strong candidate is weighing other offers. The other gains are practical:

• Faster acceptance. The candidate signs from their phone the moment they decide, so you lock in the hire before a competing employer can.
• Clean proof of acceptance. Each signed offer carries a certificate showing who signed, when, and from what IP address, which protects the company if terms are ever disputed.
• Onboarding right behind it. Send the NDA and policy forms as their own documents the same day the offer is accepted, so a new hire signs everything while the momentum is there.
• No per-recruiter cost. Whether one person or the whole team sends offers, you pay the same flat rate, even during a hiring surge.

Recruiters, in-house HR teams, and hiring managers use SignSend for exactly this: send the offer, get it accepted fast, keep proof, and not pay per seat to do it.

Most e-signature tools are priced per user, commonly $10 to $25 per person each month on entry plans, with templates and bulk features pushed to higher tiers. For an HR team where several people send offers, those seats add up fast.

SignSend is free today: the Free plan covers three documents a month with up to two signers each, with no per-user fee and no seat to buy, so a small team that hires occasionally pays nothing. Paid tiers are announced but not yet live, Pro at $12 a month and Business at $29 a month are coming soon. Against $25 per user each month elsewhere, a team making a few hires a year can run on the free plan and still get the full audit trail on every accepted offer.

An accepted offer is the start of onboarding, not the end of hiring, so it helps to line up the rest of the paperwork behind it. Many HR teams pair the offer letter with an NDA, a policy acknowledgment, and any role-specific agreements, sending each one as its own document so the new hire can sign them back to back. Keep a clean copy of each form on your side, update the name, title, salary, and start date, and each one takes seconds to send. Every signed file comes back with its own audit trail and its own secure link, ready for the personnel file.
