Signable Pricing (2026): Plans, Cost Drivers and Buyer Fit

Signable has five pricing options verified in May 2026, all in GBP plus VAT:

Pay As You Go — £1.50 per envelope. No monthly fee. Suitable for occasional or unpredictable use. Full feature access per envelope sent. After the 14-day free trial, this is the default option if no plan is selected.

Small — £29+VAT/month. 50 envelopes per month. Unlimited users. Includes templates, custom branding, audit trails and automated reminders. Annual billing gives one month free (equivalent to approximately £26.50/month).

Medium — £69+VAT/month. 150 envelopes per month. Everything in Small, plus bulk send, in-person signing and API access.

Large — £169+VAT/month. 400 envelopes per month. Adds Zapier, Xero and Salesforce integrations. REST API included.

Corporate — £239+VAT/month or £2,629+VAT/year. 750 envelopes per month on monthly billing; 9,000 envelopes per year on annual billing. Bespoke pricing available above 750 envelopes/month for high-volume organisations.

PAYG (£1.50/envelope) is right when monthly envelope volume is low and unpredictable. If you send fewer than 20 envelopes per month on average, PAYG (£30/month at 20 envelopes) is close to or cheaper than Small (£29/month for up to 50 envelopes), and avoids a standing subscription commitment.

Small (£29+VAT/month) is the right entry point for most growing UK SMBs. A small accountancy practice, letting agent, HR team or freelancer sending 20–50 documents per month will find Small provides the right capacity with enough headroom for modest growth. Annual billing at approximately £26.50/month equivalent is worth committing to once the workflow is validated.

Medium (£69+VAT/month) becomes relevant when monthly volume consistently exceeds 50 envelopes, or when bulk send and API access are needed. Estate agents managing multiple tenancy agreements per week often move to Medium within 3–6 months of adoption.

Large (£169+VAT/month) fits teams at 150+ envelopes/month, especially when Zapier or Xero workflow automation is a requirement. The per-envelope effective rate drops to £0.42 at full volume utilisation.

Corporate (£239+VAT/month) is designed for teams sending 400–750 envelopes per month. Annual billing at £2,629+VAT/year (9,000 envelopes) works out to approximately £0.29 per envelope, making it cost-effective at scale.

Envelope volume is the sole cost driver on Signable. Unlike most SaaS tools, there are no per-seat fees, no feature add-ons requiring separate purchase, and no user count limits on paid plans. Every upgrade decision reduces to one question: does actual monthly envelope volume exceed the current plan's allocation?

Annual billing saves approximately one month's cost across plans (annual pricing is quoted as one month free). The saving is real but only beneficial if the workflow is consistent — a business sending 50 envelopes per month in some months and 5 in others may prefer monthly flexibility until volume is predictable.

Seasonal spikes are the most common planning mistake. A conveyancing firm, estate agent, or accountancy practice may have months where envelope volume doubles. The plan should be sized for the peak month, not the average — or the team needs a process for temporary plan upgrades during busy periods.

VAT is additional on all Signable plans. UK businesses registered for VAT can reclaim it; unregistered sole traders and small businesses should factor the VAT-inclusive cost into their comparison.

Freelance consultant sending 8 engagement letters per month: PAYG at £1.50/envelope costs £12/month. Small at £29/month is more expensive for this volume. PAYG is the right choice unless the freelancer expects significant growth in client numbers within the next 6 months.

Small HR team processing monthly employment contracts and onboarding forms (30 envelopes/month): Small plan at £29+VAT/month for 50 envelopes with headroom for growth. Annual billing at approximately £318+VAT/year including one month free. Cost per envelope at 30/month: approximately £0.97.

Letting agent managing a portfolio of 200 rental properties (80–120 envelopes/month): Medium plan at £69+VAT/month for 150 envelopes. Peak months at 120 envelopes are within Medium's allowance. Annual commitment valid once the average month consistently exceeds 50.

Accountancy practice with 15 fee-earners (200–300 envelopes/month): Large at £169+VAT/month for 400 envelopes with Zapier and Xero integration. Provides the right headroom and workflow automation to reduce manual admin at this volume.

Foxit eSign Essentials (~$8/user/month annual) provides approximately 250 envelopes/year per user. At one user, this is ~21 envelopes/month for ~$8/month. Signable Small at £29+VAT/month gives 50 envelopes/month. Foxit wins on low-volume per-user cost; Signable wins on UK data hosting, GBP pricing and volume flexibility. If the buyer also needs PDF editing, Foxit PDF Editor+ (~$13.75/month) includes both editing and 150 eSign envelopes/year in one plan.

DocuSign Personal (~$15/month for 5 envelopes/month) is dramatically more expensive per envelope for volume users. Only compare DocuSign when complex CLM, advanced authentication, or Salesforce Sales Cloud deep integration are genuine requirements.

Adobe Acrobat Sign is bundled into Adobe Acrobat plans. Only worth evaluating if the team already pays for Adobe Acrobat. Standalone pricing is higher than Signable for comparable UK volumes.

HelloSign (Dropbox Sign) is US-hosted and comparable in simplicity. Does not offer UK data hosting or UK-native legal compliance framing. Better evaluated if the team already uses Dropbox Business as its primary file storage.
