Are electronic signatures legal for a small business?

Yes, in the US an electronic signature generally has the same legal standing as one on paper, for most everyday business documents. Quotes, service agreements, engagement letters, and consent forms are all fair game. A short list of documents is excluded, and how you collect the signature still matters.

This guide explains the federal and state rules, what they leave out, and the habits that make an e-signature easy to stand behind. It is general information, not legal advice. For a high-value contract, or anything in the excluded list below, ask a lawyer.

The federal rule: the ESIGN Act

The Electronic Signatures in Global and National Commerce Act, usually called ESIGN, is the federal law. Its core rule is that a signature, contract, or record may not be denied legal effect, validity, or enforceability only because it is electronic.^[1]

The law defines an electronic signature broadly: an electronic sound, symbol, or process attached to or logically linked with a record, and made or adopted by a person who intends to sign it.^[2] A typed name, a drawn signature on a phone screen, or a click on an "I agree" button can all qualify. The intent to sign is what counts.

ESIGN does not force anyone to use e-signatures. The law says it does not require any person to agree to use or accept electronic records or signatures.^[1] A customer who wants to sign on paper can still ask to.

The state rule: UETA

State law matters too. The Uniform Law Commission approved the Uniform Electronic Transactions Act, or UETA, in 1999 as a model for states to adopt.^[3]

Its central rule matches ESIGN. A record or signature may not be denied legal effect only because it is electronic, and if a law requires a signature, an electronic signature satisfies it.^[3] States adopt the model as their own statute, sometimes with changes. Massachusetts, for example, put the same four rules into section 7 of chapter 110G of its General Laws.^[4]

ESIGN allows a state that enacts UETA as approved in 1999 to modify or supersede part of the federal rule.^[5] The result in most cases is the same, but the details live in your state's statute, so check the version that applies to you.

UETA applies only when both sides have agreed to do business electronically. That agreement can be shown by the context and the parties' conduct, and someone who agrees once may refuse to do the next transaction electronically.^[3]

Documents the federal law does not cover

ESIGN lists exceptions.^[6] Paraphrased, the federal rule does not apply to these.

• Wills, codicils, and testamentary trusts.
• Adoption, divorce, and other family law matters.
• Most parts of the Uniform Commercial Code, with a few named exceptions such as the rules on sales and leases of goods.
• Court orders, notices, and official court documents.
• Notices that utility service will be cut off, notices of default, foreclosure, or eviction on a person's main home, and notices that health or life insurance will end.
• Product recall notices where a product risks health or safety, and documents that must travel with hazardous materials.

UETA's model text has a similar list, including wills and most of the Uniform Commercial Code.^[3] Very few of these touch a typical service business, but a landlord, a property manager, or a firm handling estates should check carefully.

Extra steps when a law requires paper for consumers

Some laws require a business to give consumers certain information in writing. If you want to deliver that information electronically, ESIGN adds conditions.^[1]

• The consumer must agree to receive it electronically, and must not have withdrawn that agreement.
• Before agreeing, they must be told they can get it on paper, and how to withdraw consent.
• They must agree in a way that shows they can open the format you will use.
• Withdrawal must take effect within a reasonable time.

This applies to required disclosures, not to every contract. If you are unsure whether a law requires a written notice for your industry, that is a good question for a lawyer.

Records you must be able to produce

Where a law requires you to keep a contract or record, an electronic copy works if it accurately reflects the information and stays accessible to everyone entitled to it for the required period.^[1] A signed PDF that only lives in one employee's email is a weak record. A copy saved on the customer's file is a better one.

How to make an e-signature hold up

Under UETA, a signature is attributed to a person if it was their act, and that can be shown in any manner, including the security procedure used to identify them.^[3] In practice, the questions in a dispute are who signed, whether they meant to, and whether the document changed afterwards.

1. Send the document to a contact you know. An email address or phone number already on the customer's record links the signature to that person.
2. Make the intent clear. Label the button or field so the signer knows they are signing, not just reading.
3. Get agreement to sign electronically. A line such as "I agree to sign this document electronically" covers the UETA point about both sides agreeing.
4. Give the signer a copy. Send the signed version to them as soon as it is complete.
5. Keep the record with the customer. Store the signed document on their file, where your team can find it years later.
6. Offer paper on request. Nobody can be forced to sign electronically.

Signing and paying in one step

For a service business, the signature usually sits next to money. A roofer needs the estimate approved and a deposit paid. An accountant needs the engagement letter signed before work starts.

In Pinn.Media CRM you can send proposals, quotes, and contracts that customers sign online, with several signers when a deal needs both homeowners or two business partners. You can see when each person has signed. The documents sit on the customer record, so the signed copy is with everything else you know about them.

Estimates in payments let a customer accept a quote and pay the deposit from the same page. See how a professional services firm or a home services business gets agreements signed, or read our guide to following up an estimate.
