Best for a pay-per-contract signing API
eSignatures.io charges $0.49 a contract from prepaid credits, with no subscription, and it's built around an API plus Zapier and Make. It only does simple electronic signatures, and ID checks and SMS cost extra on top. If you sign under the legal levels Europe asks for, it won't do.
Who eSignatures.io is for
- Fits if you send contracts in bursts and would rather pay per contract than per seat
- Works for developers who want signing in an app through the API
Who eSignatures.io is not for
- Not for you if you need advanced or qualified eIDAS signatures, as only simple ones are offered
- Watch out: live photo ID checks ($2.99) and SMS delivery ($0.09 a message) are billed on top
- Watch out: signed contracts are kept for a mandatory three years, according to the site
- Tight if you want a trial first: its length and limits aren't stated
- Pricey if you send a lot, with the cost falling to $0.20 only at the $100,000 top-up
Why eSignatures.io gets a 2.0
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- CValue for money$0.49 a contract from a $50 top-up, with credits that don't expire. The category's figures can't price this, and what you pay depends on how many you send: 100 contracts is $49, and ID checks ($2.99) and SMS ($0.09) are extra.
- DFree plan and trialThe pages describe a free trial but give no length or limits, and there is no free plan.
- CFeaturesFlat fee per contract, mobile-first contracts, API, Zapier and Make, signer checks, links, kiosk mode and bulk send. Gap: only simple electronic signatures, with no advanced or qualified eIDAS signatures.
- CEase of useNo store rating on record. You connect it through its API, Zapier or Make, or send from the dashboard, so there's setup first.
- BPlatforms and integrationsWeb only, with Zapier, Make, Google Drive, WordPress, HubSpot, Salesforce, Claude and ChatGPT connections and an API.

Keep eSignatures.io, or make your own?
Keep it
To replace eSignatures.io you would be making connections to other products, each kept working as those products change. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 26 of the 37 other e-signature and proposal tools grade higher.
What you could make
- Documents and templates: an app builder makes these well.
What you could not
- Connections to other products, each kept working as those products change.
- AI features, unless you pay a model provider for each request yourself.
What this rests on. eSignatures.io’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is eSignatures.io?
eSignatures is an online signing service that charges per contract sent instead of a monthly subscription. Contracts are built as responsive text rather than PDFs, and every feature is open to every customer. It can be driven from a browser, an API, Zapier or Make, or through AI assistants such as Claude and ChatGPT.
Worth knowing
- Only simple electronic signatures are offered; advanced and qualified signatures under eIDAS are not.
- Live photo ID checks ($2.99) and SMS delivery ($0.09 per message) are billed on top of the $0.49 contract fee.
- The pages read describe a free trial but do not state its length or limits.
- Signed contracts are kept for a mandatory three years, according to the site.
Key features
- Flat fee per contract
- A contract costs the same whether it has one signer or fifteen, two pages or twenty. There are no seat fees and no envelope caps.
- Mobile-first contracts
- Contracts are responsive text instead of PDFs, so signers on a phone do not have to pinch and zoom. The signed result is delivered as a PDF.
- API, Zapier and Make
- A single API request sends a contract, and the service also connects to Zapier and Make. Contracts can be drafted and sent from Claude or ChatGPT.
- Signer checks
- Signers can be asked for a one-time code by email or SMS, or for a live photo ID check. Photo ID checks cost $2.99 each and SMS delivery $0.09 per message.
- Links, kiosk mode and bulk send
- A contract link lets anyone sign, can be embedded on a site or shared as a QR code, and kiosk mode lets people sign one after another on a shared tablet.
- Data location and branding
- Contracts can be stored in the US, Frankfurt, London, Sydney or Canada. Your logo, company name, fonts and email domain can be used in the signing flow.
