Part 01 · Overview

Welcome

What it is, who it suits, its grades and the ten things to know first

2.0

GPA, above 2 of the 37 other e-signature and proposal tools we grade

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.

To get you started, here are 9 things to know about eSignatures.io, taken from its own pages and our grades.

If you sign under the legal levels Europe asks for, it won't do.

  6. 6

    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.

  7. 7

    API, Zapier and Make

    That is against the other e-signature and proposal tools we grade, on value, the free plan, features, ease of use and platforms.

  9. 9

    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.

The report card

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.

ToolGPA report cardeSignatures.ioGraded Nov 12, 2026
SubjectGradeComment
Value for moneyC$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.
Free plan and trialDThe pages describe a free trial but give no length or limits, and there is no free plan.
FeaturesCFlat 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.
Ease of useCNo store rating on record. You connect it through its API, Zapier or Make, or send from the dashboard, so there's setup first.
Platforms and integrationsBWeb only, with Zapier, Make, Google Drive, WordPress, HubSpot, Salesforce, Claude and ChatGPT connections and an API.
Grade point averageFair, out of 4.02.0

An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.

  • 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

2/37

Other e-signature and proposal tools it is graded above

eSignatures.io's GPA of 2.0 is higher than 2 of the 37 other e-signature and proposal tools we grade, and level with 9.

It stands best on platforms and integrations (B, above 2 of 37) and worst on free plan and trial (D, above 2).

Each grade against the category

Every bar is all 38 e-signature and proposal tools we grade, cut by the letter each got. eSignatures.io’s own letter is outlined.

  • CValue for moneyAbove 9 of 37
  • DFree plan and trialAbove 2 of 37
  • CFeaturesAbove 0 of 37
  • CEase of useAbove 1 of 37
  • BPlatforms and integrationsAbove 2 of 37

Keep it, or make your own?

Whether this is something you could build for yourself with an AI app builder, and what you would give up.

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.
