eSignatures.io vs Signable (2026): which should you pick?

Pick eSignatures.io if

• 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

Look elsewhere if

• 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

Pick Signable if

• Fits if lots of people in your office send the odd contract, as users are unlimited
• Works for UK teams that want documents held in the UK

Look elsewhere if

• Pricey if you're one person, since the whole £40 a month plus VAT lands on you
• Tight if you send more than 300 envelopes a year, as each one over costs a fee
• Skip it if you need bulk send, teams or the API at a published price, as they need Business through sales
• Watch out: prices are in pounds, exclude VAT and are billed yearly, and SSO is Enterprise only
• Not for you if your signers are outside the UK and need text-message checks, or you want a phone app

eSignatures.io

• 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.

Signable

• Prices are in pounds, exclude VAT and are billed yearly; the envelope allowance is a yearly total available upfront.
• Pay As You Go has no subscription and charges from £2.60 per envelope; going over a plan's allowance without a bundle adds a fee per envelope.

• Two-factor checks for signers by text message work in the UK only.

eSignatures.io

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.

Signable

Unlimited users

Plans charge by envelopes, not seats, so a whole organization can be added at no extra cost, with user roles and teams to split it up.

AES and QES signatures

Advanced electronic signatures and an eSeal on every plan; qualified electronic signatures, for documents that need verified identity, from Business.

Templates, reminders and bulk send

Reusable templates with pre-filled fields and field tags, automatic reminders and expiry, signing order, and bulk send from Business.

AI-assisted fields

Suggests where signature fields and other inputs belong in a document before it is sent.

API and embedded signing

The Signable API, from Business, lets other software send envelopes and embed the sending and signing pages inside its own app.

UK hosting and compliance

Data is hosted in the UK on AWS; Signable is ISO 27001 and Cyber Essentials certified and follows eIDAS, ESIGN and UETA.
