Use cases

# Electronic signatures for every kind of agreement

How freelancers, landlords, small businesses, HR teams and startups sign contracts, NDAs, leases and offer letters with Attest, with proof anyone can check.

- ## [E-signatures for freelancers and consultants](https://attest.datahubz.com/use-cases/freelancers-and-consultants)
Freelancers and consultants need an e-signature that proves exactly which contract, statement of work or change order a client approved, and when, while keeping the rates and terms inside it private. Attest does both for $5 a month for 20 documents: every document is end-to-end encrypted, each client approves with a passkey only they control, and anyone can verify the signed copy for free, even without Attest.
- ## [How to sign an NDA you can prove](https://attest.datahubz.com/use-cases/nda)
Sign it with an e-signature that records who signed which exact version, and when, and that keeps the NDA itself confidential: with Attest, the NDA is end-to-end encrypted, each party approves with a passkey only they control, and the sealed copy verifies for free, even without Attest. To show that the agreement exists without revealing it, share a zero-knowledge proof that you and the other party signed it, and the date it was completed.
- ## [How to sign client contracts and statements of work](https://attest.datahubz.com/use-cases/client-contracts-and-statements-of-work)
Sign the master agreement once, then send each statement of work and change order as its own document that names the agreement it belongs to, so every scope and price a client approved has its own signatures, date and fingerprint. With Attest, each client signer approves with a passkey only they control, every document is end-to-end encrypted, and the sealed copy verifies for free, even without Attest, on the Signing plan at $5 a month for 20 documents.
- ## [E-signatures for agencies: contracts and change orders](https://attest.datahubz.com/use-cases/agencies)
An agency needs each retainer, statement of work, change order and creative sign-off approved by the right person at the client, on the exact version, with a record that answers later questions about scope, revision rounds and fees. Attest gives every signer their own passkey signature on that exact file, keeps unreleased client work private with end-to-end encryption, and seals a copy anyone can verify for free, on the Signing plan at $5 a month for 20 documents per person who sends.
- ## [How contractors get estimates and change orders signed](https://attest.datahubz.com/use-cases/contractors)
Have the client sign each estimate, job contract and change order before the work it covers starts, so every price and every change in scope has a signature, a date and an exact version you can show later. With Attest the client signs on their phone with a passkey only they control, with no app and no account, and both of you keep a sealed copy that verifies for free, even without Attest, for $5 a month for 20 documents.
- ## [E-signatures for landlords: leases and renewals](https://attest.datahubz.com/use-cases/landlords-and-property-managers)
Send each lease, renewal and move-in condition report for signature by every tenant and guarantor, so the rent, the terms and the condition of the home at move-in are on one signed record that you and your tenants both hold. With Attest each tenant signs on their phone with a passkey only they control, the lease is end-to-end encrypted, the signed copy verifies for free even without Attest, and the Signing plan costs $5 a month for 20 documents.
- ## [How to sign offer letters and employment agreements](https://attest.datahubz.com/use-cases/offer-letters-and-employment-agreements)
Send the offer letter or employment agreement as a PDF for the candidate's signature with a deadline, and countersign it, so the salary, start date and terms both sides accepted are on one record with both signatures. With Attest the salary stays private because every document is end-to-end encrypted, the candidate signs on their phone with a passkey only they control and no account, and both sides keep a sealed copy that verifies for free, even without Attest.
- ## [How to sign a roommate agreement online](https://attest.datahubz.com/use-cases/roommate-agreements)
Write down what you agreed, such as each person's share of the rent, bills and deposit, the notice before moving out and the house rules, save it as a PDF and have every roommate sign it, so everyone holds the same signed copy if money or move-out questions come up later. With Attest each roommate signs on their phone with a passkey only they control, with no account to create, and your first 2 documents are free, in total, enough for the agreement and one later update.
- ## [How to collect handbook and policy acknowledgments](https://attest.datahubz.com/use-cases/policy-acknowledgments)
Send each employee the handbook or policy as a PDF that ends with an acknowledgment page they sign, one document per person, so you hold a signed, dated record of exactly which version each employee received. With Attest each employee approves with a passkey only they control, and if someone later says they never saw the policy, the signed copy shows their signature on that exact version, which anyone can verify for free.
- ## [E-signatures for vendor and supplier agreements](https://attest.datahubz.com/use-cases/vendor-and-supplier-agreements)
Sign them with an e-signature that proves which exact version each company signed, and when, and that keeps the prices and terms inside private: with Attest, every supplier agreement is end-to-end encrypted, each signer approves with a passkey only they control, and both companies hold the same sealed copy, which anyone can verify for free, even without Attest. Suppliers never pay and create no account, and one agreement can carry up to 20 signers, so your approver, your legal contact and the supplier's signatory all sign the same document.
- ## [E-signatures for sales quotes and order forms](https://attest.datahubz.com/use-cases/sales-quotes-and-order-forms)
Send the quote or order form as a PDF for the customer to sign, with an expiry date that matches how long the quote is valid, so the signed copy proves the exact prices and terms they accepted, and when. With Attest, the customer approves with a passkey only they control, with no account and nothing to pay, every document is end-to-end encrypted so your pricing stays between you and the customer, and the Signing plan is $5 a month for 20 documents.
- ## [Startups: SAFE notes, term sheets and board consents](https://attest.datahubz.com/use-cases/startups)
Founders can sign SAFEs, term sheets and board consents electronically, and Delaware's corporation law, by default, lets a board act without a meeting when every director consents in writing or by electronic transmission. Attest keeps those documents end-to-end encrypted, so not even Attest can read a valuation cap, has every founder, investor and director approve with a passkey only they control, and gives every party the same sealed copy that investors' lawyers can verify for free, for $5 a month for 20 documents.
- ## [E-signatures for partnership agreements](https://attest.datahubz.com/use-cases/partnership-agreements)
Have every partner sign the same final version, and keep proof of who signed it and when that still holds years later: with Attest, each partner approves with a passkey only they control, the agreement is end-to-end encrypted so its ownership split and contributions stay private, and every partner keeps the same sealed copy, which anyone can verify for free, even without Attest. When a bank, a customer or a new partner needs to know the partnership exists, a partner who signed can share a zero-knowledge proof that they, or they and a named co-signer, signed it, and the date it was completed, without revealing its terms.
- ## [Bill of sale for a car or equipment, signed online](https://attest.datahubz.com/use-cases/bill-of-sale)
Buyer and seller can sign a bill of sale online, each on their own phone at the handover, and Attest records the exact document both approved, with its price and date, in a sealed copy each of them keeps and anyone can verify for free. For a car or other titled vehicle, the signed bill of sale is your record of the sale, and ownership moves through the state's title transfer: the seller signs over the certificate of title, with that signature notarized in some states, such as Ohio for a paper title.
- ## [How to sign a personal loan agreement online](https://attest.datahubz.com/use-cases/personal-loan-agreements)
Write down the amount, the repayment schedule and any interest, then have the lender and the borrower both sign, so you both hold the same record of what was agreed: with Attest, each of you approves with a passkey only you control, the agreement is end-to-end encrypted, and you both keep the same sealed copy, which shows which version each of you approved with your own passkey, and when. Your first 2 documents are free, in total: one for the loan agreement and one for the release the lender signs when the loan is repaid.
- ## [Photo and model releases, signed on a phone](https://attest.datahubz.com/use-cases/photo-and-model-releases)
Have the person photographed sign the release before you use their image, or, for a minor, a parent or guardian, and with Attest they can sign it on their own phone at the shoot, with no account, app or fee. Each signature is made with a passkey only the signer controls and sealed into a copy you both keep, which shows which release each signer approved with their own passkey, and when, and verifies for free, even without Attest.
- ## [Nonprofits: volunteer and grant agreements](https://attest.datahubz.com/use-cases/nonprofits)
Nonprofits can send volunteer agreements, grant agreements and partner MOUs for e-signature without asking volunteers, grantees or partners to create an account or pay, and keep a sealed copy of each that funders and auditors can check for free. With Attest, every document is end-to-end encrypted, each signer approves with a passkey only they control, and the Signing plan is $5 a month for 20 documents.
- ## [Schools and tutoring: enrollment and permission forms](https://attest.datahubz.com/use-cases/schools-and-tutoring)
Tutoring centers, music and language schools, camps and private schools can send enrollment agreements and permission forms for a parent or guardian to sign on their phone, with no account, app or fee for the family. With Attest, each family's form is end-to-end encrypted and sealed into a copy the school and the family both keep, which shows which version each parent approved with their own passkey, and when, and anyone can verify it for free.
