Our verdict

This Signable review looks at a UK e-signature service that has built its whole pitch around two ideas: you should not pay per user, and you should be able to ring a person in Britain when something goes wrong. Signable is a good fit for small and mid-sized UK organisations that send a predictable number of contracts each month, want UK-hosted data, and would rather not train staff on an enterprise contract platform. It is a weaker fit for companies that need heavy workflow automation, contract drafting, or identity checks on signers outside the UK.

NerdBible has not run hands-on tests of Signable for this review. What follows is an editorial assessment built from Signable's own plans, features, security and legal pages, and from what independent reviewers and verified users report. Where those sources disagree, we say so.

What is Signable and who is it for?

Signable is an electronic signature platform run from Bristol in England. You upload a document, drag signature, date and text fields onto it, choose who signs and in what order, and send it as an "envelope". Signers open it in a browser or on a phone, sign, and everyone receives the completed PDF with an audit trail attached. Signers do not need their own Signable account.

The company's pages are aimed squarely at UK businesses: accountants, letting agents, recruiters, schools and colleges, charities and local councils appear throughout its case studies and integration list. It names industry systems it already connects to, such as ProSolution for further education, My Digital for contractor accountants and SME Professional for property managers. If you work in one of those sectors and already use one of those systems, that is a meaningful head start.

Signable is less suited to large multinationals. Its strongest identity feature, SMS verification of signers, is limited to UK mobile numbers, and its Qualified Electronic Signature option is still listed as coming soon. Teams that need a full contract lifecycle tool, with clause libraries, redlining and approval chains, will also find it thin by design.

Key features

Signable's features page lists more than thirty capabilities. The ones most buyers will care about are these.

  • Templates and field tags. Any document can be saved as a reusable template, and field tags in a Word or PDF file can place signature fields automatically when the file is uploaded. Pre-fillable fields let you complete parts of a template before sending.
  • Signing order and multi-party signing. You can send to everyone at once or set a strict sequence, which matters for documents that need a manager's countersignature after a client signs.
  • Auto-reminders and auto-expire. Signable can chase signers automatically and close an envelope after a set date, which is useful for time-limited offers and quotes.
  • Bulk send. One document can go to many recipients in a few clicks, for example a policy update that every employee must acknowledge. On the plans page bulk send is included from the Medium plan upwards.
  • Widgets. A single link or embedded form can generate many signed documents, which suits sign-up forms and consent forms on a website.
  • AI-assisted fields. A newer feature suggests where signature and input fields belong, to cut set-up time on unfamiliar documents.
  • Branding and languages. You can add your logo and colours, and the signing experience is offered in six languages.
  • API, embedded sending and embedded signing. Developers can put Signable's preparation page or signing page inside their own application, which is how the industry integrations above are built.
  • Integrations. Signable lists Google Drive, Google Docs, Dropbox, HubSpot, Slack, Zapier and Make. Completed documents can be pushed to cloud storage automatically.

There is also a CSV data export for everything in your account, which is worth knowing if you ever decide to move to another provider.

How much does Signable cost?

Our page shows current prices from our own data, so here we describe how the plans are built rather than what they cost.

Signable prices by envelope, not by seat. Every plan, including pay-as-you-go, includes unlimited users and unlimited templates. That is the single biggest difference from rivals that charge per sender: an office where ten people each send two contracts a month pays for twenty envelopes, not ten licences.

  • Pay as you go: no subscription; you buy envelopes individually or in credit packs.
  • Small, Medium, Large and Corporate: monthly or annual subscriptions with a fixed envelope allowance, ranging from a few dozen to several hundred envelopes a month. The cost per envelope falls as you move up. Annual billing includes a month free and gives you the year's envelopes up front.
  • Bespoke: a quoted plan for higher volumes.

Features step up with the tier. Branding and API access start at Small; teams, bulk send, concierge onboarding and single sign-on arrive at Medium; IP allowlisting, an account manager and unlimited training come with Large; template and branding set-up by Signable's staff are included at Corporate. Advanced Electronic Signatures, digital signing and two-factor authentication for signers are on every plan.

Two practical notes. First, plans are capped by envelope count, so "unlimited documents" is not how Signable describes any tier. Second, Signable offers a 14-day free trial and says no credit card is needed to start.

Is Signable legally binding?

Signable's legal page states that its signatures are legally binding in the UK and across most of the world, and its security page says it complies with the EU and UK eIDAS rules and with the US ESIGN Act and UETA. Signable explains that an enforceable e-signature rests on intent, consent, integrity of the signed document, and an audit trail. Each completed document carries a tamper-evident certificate with a document fingerprint, signer details, IP addresses and timestamps for every step.

Signable is clear about the three eIDAS signature levels. Simple electronic signatures cover most everyday agreements. Advanced Electronic Signatures, which add identity verification through an SMS code, are available on all plans but only for UK signers. Qualified Electronic Signatures are listed as coming soon. If a regulator or counterparty requires a qualified signature today, Signable cannot provide it yet. For questions about whether a particular document can be signed electronically in your situation, speak to a solicitor.

Is Signable safe?

On security, Signable's claims are specific and checkable. It says it is certified to ISO 27001 and holds the UK government-backed Cyber Essentials certification. All customer data is stored and processed in the UK, in Amazon Web Services' London region. Data is encrypted in transit and at rest with AES-256, with encryption keys managed in AWS hardware security modules. Signable says its staff cannot view your documents without your explicit permission and that every access is logged. It runs automated vulnerability scans and commissions penetration tests, takes daily database backups, and publishes a status page. The security page gives an availability figure for the previous calendar year of a little under 99.8 percent.

Account-side controls include two-factor authentication for logins, password protection on individual documents, user roles, IP allowlisting and single sign-on on higher plans. For UK organisations that must keep personal data in the UK, the London hosting is a genuine selling point that several larger US rivals only offer on enterprise contracts.

What is Signable's customer support like?

Support is the feature Signable leans on hardest. Its pages promise UK-based support "from real humans, every time" on every plan, and higher tiers add concierge onboarding, an account manager and free training. Independent sources back this up: on Trustpilot, Signable holds a rating of about 4.5 out of 5 from more than 500 reviews, and support quality is the most common theme in positive reviews. Users describe quick, clear answers. Negative reviews are fewer and tend to concern template set-up and billing disputes rather than support speed.

What could be better

  • Volume caps. Envelope-based pricing is efficient for many senders with modest volumes, but a small team sending very high numbers of documents may pay more than with a per-seat rival that includes unlimited sending.
  • UK-only identity checks. SMS verification for Advanced Electronic Signatures works only for UK signers, so international counterparties sign at the simple level.
  • No qualified signatures yet. QES is announced but not available.
  • Limited automation. There is no conditional logic or complex routing of the kind found in enterprise suites, and no contract drafting or negotiation tools.
  • A modest integration list. The main connectors are Google, Dropbox, HubSpot, Slack, Zapier and Make. Teams built on Salesforce or Microsoft Dynamics will need Zapier or the API.

Who should choose something else?

If you sign only a handful of documents a year, a free signing tool or the signature features already inside your PDF editor may be enough. If you work mainly with signers in the EU or the US and need verified identities, look at providers with international ID verification. If your company is standardised on Microsoft 365 or Salesforce and wants signing inside those apps, an enterprise platform such as Adobe Acrobat Sign is the more natural fit. And if you need a tool that drafts, negotiates and stores contracts, you want contract lifecycle management software, not a signing service.

Is Signable worth it?

For a UK small or mid-sized business with several people who send documents, yes, Signable is one of the more sensible choices. The unlimited-user model removes the most annoying cost of e-signature software, UK data hosting and UK support solve real compliance and service problems, and the feature set covers what most offices actually do: templates, reminders, signing order, bulk send and an audit trail that stands up as evidence. It earns its place on our list as the pick for UK SMEs. Its limits are equally clear: volume caps, UK-only advanced signatures and no qualified signatures yet.

What other reviewers found

Signable has not been reviewed by the large general technology outlets as often as the US market leaders, so the independent picture comes mostly from specialist software reviewers and verified user platforms.

  • The Business Dive scored Signable 4 out of 5, praising its flexible pay-as-you-go option and clean interface, but marked it down for the lack of a central dashboard and limited signature management.
  • Authencio saw it as a strong budget choice for micro-businesses and agencies with variable volumes, while noting it lacks conditional logic and becomes less cost-effective at high monthly volumes.
  • Cllimber highlighted unlimited users, API access on standard plans and UK data residency, and flagged that SMS verification works only for UK recipients.
  • On Trustpilot, users rate Signable about 4.5 out of 5, most often praising ease of use and support, with occasional complaints about template handling.

The reviewers agree on the core: Signable is easy to use, its support is unusually good, and per-envelope pricing with unlimited users is its defining advantage. They disagree mainly on value at scale. Reviewers looking at low-volume users call it a bargain; those modelling higher volumes point out that a per-seat plan with unlimited sending can work out cheaper. For a buyer, the practical step is to count how many envelopes your whole organisation sends in a typical month, then compare that with the envelope allowance on Signable's plans before you compare it with anyone else.

Frequently asked questions

Is Signable legally binding in the UK?

Signable says its electronic signatures are legally binding in the UK under UK eIDAS rules and related legislation, and admissible as evidence. Each completed document carries an audit trail and a tamper-evident certificate recording who signed, when and from which IP address. Some documents, such as certain deeds, carry extra formalities, so check the rules for your document type or ask a solicitor if you are unsure.

Does Signable charge per user?

No. Signable includes unlimited users on every plan, including pay-as-you-go. You pay for envelopes instead, either individually or through a monthly or annual allowance that grows with each tier. This makes it attractive for offices where many people send a few documents each, because adding a colleague does not add a licence fee.

Where does Signable store my documents?

According to its security page, all Signable data is stored and processed in the UK, in Amazon Web Services' London data centre. Documents are encrypted in transit and at rest using AES-256, keys are held in hardware security modules, and Signable staff cannot open your documents without your explicit permission. The company is ISO 27001 and Cyber Essentials certified.

Does Signable offer a free trial?

Yes. Signable offers a 14-day free trial, and its plans page says you can start without a credit card or contract. The trial lets you send real envelopes, so it is a good way to check how your templates, signing order and reminders work before you choose between pay-as-you-go and a monthly or annual plan.

Can Signable verify a signer's identity?

Signable offers two-factor authentication for signers on all plans, which sends a one-time code by SMS before the signer can open the document. That check upgrades the signature to an Advanced Electronic Signature, but it currently works only for UK mobile numbers. Qualified Electronic Signatures, the highest eIDAS level, are listed as coming soon.
