Sign NDA Online: NDA Electronic Signature and Online Signing Software

Yes. An NDA 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 both parties consent to sign electronically and the document keeps an audit trail. A non-disclosure agreement is an ordinary business contract, so the same e-signature rules that apply to any contract apply to it.

For the signature to hold up, each party has to intend to sign, the signature has to be tied to that specific NDA, and the platform has to record a verifiable trail of who signed and when. SignSend captures all three on every agreement, which gives you far stronger proof than a scanned signature on a PDF if a dispute over confidentiality ever arises.

An NDA is signed by a person with authority to bind the company, usually an owner, officer, or an employee with signing authority such as a manager or department head. When you send a non-disclosure agreement to a vendor, contractor, or potential partner, the person who signs should be authorized to commit that organization to keeping information confidential.

In practice, founders sign for early-stage startups, an officer or legal contact signs for larger companies, and an individual contractor signs for themselves. With SignSend you assign each signature field to a named signer, so the right person at each company signs the right place, and the audit trail records exactly who that was.

The main reason is speed before sharing. A deal, demo, or contractor engagement often cannot start until the NDA is signed, and an agreement that used to take days of mailing and scanning now gets signed in minutes. The other gains are practical:

• Protection starts sooner. The counterparty signs from their phone the moment they agree, so confidentiality is in place before you share anything sensitive.
• Clean proof of agreement. Each signed NDA carries a certificate showing who signed, when, and from what IP address, which matters if you ever need to enforce it.
• Mutual NDAs in one flow. Send a two-way agreement and have both sides sign and counter-sign in a single secure link instead of trading versions by email.
• No per-sender cost. Whether one founder or a whole team sends NDAs, you pay the same flat rate, even during a busy fundraising or hiring stretch.

Startups, agencies, recruiters, and small businesses use SignSend for exactly this: send the NDA, get it signed 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. If several people on your team send NDAs, those seats add up fast.

SignSend Pro is a flat $12 a month with unlimited NDAs and no per-user fee, so a small team pays $12, not $75. The $29 Business plan adds API access and team features for higher volume, and a free plan covers three documents a month if you only send the occasional agreement. Across a year, the flat model is roughly $144 against $600 or more for the same signatures, templates, and audit trails.

SignSend handles both directions of confidentiality. For a one-way NDA, you add a single signer and send it. For a mutual NDA, you add both parties and each side signs and counter-signs from the same secure link, so you are not emailing versions back and forth. Save each version as a template and you can send the right one in seconds with just the counterparty name updated.

Many teams also send the NDA alongside other agreements. A startup might bundle the NDA with a contractor agreement, and an HR team often sends the NDA with the offer letter and policy forms so a new hire signs everything in one sitting. Each signed file lands in your records with its own audit trail, ready for the deal folder or personnel file.
