Best E-Sign Software for UK Businesses

Quick answer

Signable is the cleaner choice for UK businesses that mainly need straightforward electronic signatures, templates, audit trails, and predictable envelope pricing. Foxit is stronger when signatures are part of a broader PDF workflow involving editing, OCR, forms, document comparison, redaction, and PDF management.

Signable pricing

Signable currently lists PAYG at GBP1.50 per envelope, Small at GBP29+VAT/month for 50 envelopes, Medium at GBP69+VAT/month for 150 envelopes, Large at GBP169+VAT/month for 400 envelopes, Corporate at GBP299+VAT/month for 750 envelopes, and Bespoke above that. Annual billing gives one month free and annual envelopes.

Foxit pricing and fit

Foxit currently focuses PDF Editor and PDF Editor+ plans. PDF Editor covers core PDF editing across desktop, macOS, and web. PDF Editor+ adds mobile apps, AI Smart Redact, and Foxit eSign with 150 envelopes/year. Foxit eSign Essentials includes 250 envelopes/year, while eSign Business includes unlimited envelopes and requires 5+ licenses.

When Signable wins

Choose Signable when the business wants a simple signing process, UK-focused e-signature workflows, unlimited users on relevant plans, API access, and clear envelope economics. It is especially attractive when PDF editing is already handled elsewhere.

When Foxit wins

Choose Foxit when document editing and signing should live together. It is better for teams handling PDFs daily, creating forms, converting files, running OCR, comparing versions, and needing signing as one part of a larger document workflow.

Decision checklist

Count monthly envelopes, check whether signers need advanced authentication, confirm where data is hosted, verify API needs, and decide whether the business also needs PDF editing. The cheapest signing tool may become expensive if staff still need a separate PDF editor.

Bottom line

Signable is the focused UK e-sign shortlist. Foxit is the broader document workflow shortlist. The right choice depends on whether your problem is signatures only or documents end to end.

Pricing and plan details in this guide were checked in May 2026 from public provider pricing pages and help documentation. Treat them as a buyer-friendly snapshot, not a contractual quote.

Legal and audit considerations

For most ordinary UK business documents, electronic signatures are widely accepted, but buyers should still check internal policy, client requirements, regulated workflows, and industry-specific rules. The practical issue is often evidence: audit trails, signer authentication, timestamps, document history, and certificate access.

If documents are high-value or disputed often, choose a tool with stronger authentication and audit controls rather than the cheapest envelope price. For routine engagement letters, onboarding forms, and approvals, speed and ease may matter more.

Envelope math

Envelope pricing only works if you know monthly volume. A business sending 10 documents a month may prefer PAYG. A business sending 200 documents a month needs a plan. A business with seasonal spikes should check whether annual envelopes, rollover rules, or plan upgrades make more sense.

Also check whether a single envelope can contain multiple documents and signers. That detail can materially change effective cost per completed workflow.
