Signable review for UK small businesses

Signable is electronic signature software built in the UK. Its job is to take a document you would normally print, sign by hand, scan and email, and move that process online: you upload the document or pull from a template, mark where each party needs to sign, send it, and receive a completed PDF with a record of what happened and when.

The unit of billing and work is the envelope. An envelope is a single document or a bundle of documents sent together to one or more signers as one signing request. That distinction matters commercially: you are charged per envelope sent, not per person using the account, which is the opposite of the per-seat model most business software uses.

What Signable is not matters just as much. It is not a document management system, a contract lifecycle platform or a CRM. It does not draft your legal terms, negotiate clauses or manage the full life of an agreement. It handles the signing step: dispatch, signature, tracking and evidence.

UK Business Stack classifies Signable as a transactional operations tool — a lightweight, defensible replacement for the printer-scanner-email loop that sits in front of almost every commercial process a small business runs.

Signable sits between the document you have prepared and the filed, completed record your business needs. The agreement is authored elsewhere — Word, Google Docs, a PDF from your accountant or a template library — and after signing, the completed PDF and its audit certificate need to live somewhere sensible: Google Drive, a SharePoint folder, a case file or your CRM.

Because it occupies only the signing step, Signable composes well. Its documented integrations with Google Drive, Google Docs, HubSpot, Slack, Zapier and Make, plus free API access on paid plans, are designed to pull documents in and push completed ones out rather than become a second place where business documents live.

The practical stack question is therefore about volume and repetition. If the same agreement types are sent repeatedly — supplier forms, client contracts, HR paperwork — templates and automation pay for themselves quickly. If you sign two documents a year, any subscription is overhead and pay-as-you-go or no tool at all is the rational answer.

The flow below reflects Signable's documented product behaviour. UK Business Stack has not run a live Signable trial for this review, so treat these steps as documented behaviour rather than tested behaviour.

Before subscribing to any e-signature tool, it is worth naming the honest alternatives. All of them can produce a signed document; they differ in evidence quality, speed and cost.

• Legal standing in the UK. Signable's legal guide states electronic signatures are legally binding in the UK under the Electronic Communications Act 2000 and the UK eIDAS regulation, and cites the Law Commission's position that electronic signatures can execute documents where a statutory signature is required. Specific document types still need individual judgement.
• Assurance levels under eIDAS. The platform supports Simple Electronic Signatures for everyday use and lists Advanced Electronic Signatures — which add verification such as two-factor authentication and tamper-evident signing — as currently available in the UK only. Qualified Electronic Signatures are listed as coming soon.
• Scots law note. Signable's legal page notes compliance work relevant to Scots law. If your contracts are governed by Scots law, confirm the current position directly with Signable before rollout.
• UK hosting and company base. Vendor pages state data is UK-hosted on AWS infrastructure, and the company describes itself as Bristol-based with a UK customer support team reachable by email, phone and live chat.
• Pricing in GBP, excluding VAT. Signable publishes UK pricing in GBP excluding VAT. All figures quoted in this review exclude VAT — add 20% for the gross cost to a VAT-registered business.
• Recent price changes. Signable's help centre published an updated price list effective 1 June 2026, with higher per-envelope and plan rates than earlier periods. Confirm current figures directly before purchase, and ask about annual lock-in if you are near a change date.
• Charity discount. Vendor pages state UK-registered charities can receive a discount on the first year of any annual plan. Verify eligibility and current terms directly with Signable.

Signable prices by envelope, not by user. Vendor documentation published in 2026 lists Pay As You Go at £1.60 per envelope, and subscription tiers of Small at £31 per month for 50 envelopes, Medium at £73 for 150, Large at £178 for 400 and Corporate at £314 for 750 — all excluding VAT. Annual billing gives one month free and the full year's envelope allowance upfront, with published annual prices of £341, £803, £1,958 and £3,454 respectively for the same tiers. Envelopes above a plan's allowance are charged at £1.60 each.

The model is transparent but has a sharp edge: overage costs can erase the saving from a mis-sized plan. A business that regularly overshoots Small is usually better on Medium than stacking overage fees. Check current figures directly with Signable, as the vendor updated prices in June 2026 and periodically adjusts plan structures.

• The bill follows volume, not value. An envelope sent is an envelope charged, whether the counterparty signs in an hour or never. Unsuccessful sends still consume allowance, so process quality affects cost.
• No permanent free tier. The trial converts to a paid or pay-as-you-go model. Teams wanting a always-free option for occasional internal signing will not find one here.
• Assurance has a ceiling. Simple signatures cover most business use, Advanced signatures are UK-only per vendor documentation, and Qualified signatures are not yet available. Regulated processes may not fit.
• Integrations are selective. The documented integration list is focused rather than exhaustive. Anything outside Google, HubSpot, Slack, Zapier, Make or the API is manual work.
• It does not manage documents. No storage strategy, no version control, no contract lifecycle. Filing completed documents is your workflow's job, and a missing filing habit creates a new sprawl of signed PDFs across inboxes.
• Some documents stay on paper. Wills, certain powers of attorney and some property or court documents may still require handwritten signatures, according to Signable's own guidance. Mixed workflows persist.
