Inkfree vs Signable
Signable charges per envelope, so your bill grows as your team does. Inkfree is the Signable alternative with a flat monthly rate — unlimited signing, all features included, no counting required.
Why Teams Choose Inkfree
Over Signable
Here's what actually changes when you switch to Inkfree.
Flat pricing, your bill doesn't grow with volume
Every envelope on Signable costs money. Inkfree's Standard and Business plans include unlimited sign requests at a flat monthly rate.
A permanent free plan, Signable doesn't have one
Inkfree's Free plan gives 3 sign requests a month, forever, with no credit card required. Signable has no free allowance; every document costs at least £1.60 pay-as-you-go.
AI Assistant, something Signable doesn't offer
Included from Standard, it detects fields and summarizes documents for signers. Signable has no AI capabilities at any tier.
Workflow controls Signable doesn't include
Scheduled sending, delayed routing, conditional routing, and approval workflows come with Standard and Business. Signable covers core sending and signing only.

Questions, answered.
What teams ask when weighing a Signable alternative.
At very low volumes — a handful of envelopes a month — Signable's pay-as-you-go rate (£1.60/envelope) can cost less than Inkfree's Basic plan, and Signable bills per account rather than per user, so a large team that sends rarely can share one plan. The comparison flips as volume grows: Inkfree Standard is $35/user/month for unlimited requests, while Signable's Medium plan is $99/month for 150 envelopes and its Large plan $242/month for 400.
Yes, on all plans — but it works by sending a one-time code over SMS, and Signable's help documentation states those codes go to UK mobile numbers only. So it is a genuine advantage for UK-only signing, and much less useful once your signers are international. Inkfree has AES on its roadmap.
Yes — Inkfree complies with eIDAS, making signatures legally valid across the UK and EU. The platform is available globally. Signable's UK-based support and GBP pricing may be preferred by teams exclusively in the UK, but Inkfree works equally well for UK businesses.
Not at all. You sign up for an Inkfree plan, rebuild your templates (most teams cover their core documents in a day), export and archive your completed documents from Signable, and you're operational. The Help Center article 'How to Switch to Inkfree from Another eSignature Platform' walks through each step.
Yes — Inkfree generates a tamper-proof audit trail for every request, recording every delivery, view, verification, signature, and decline with timestamps. When the request completes, a certificate of completion is generated and sent automatically to all parties. The trail is cryptographically sealed at the moment of final signing, so any later attempt to alter the document or its trail is immediately detectable.
How much will your document volume grow over the next 12 months? If the answer is 'a lot', Inkfree's flat pricing means your cost stays predictable regardless of volume. If your volume is stable and low, Signable's per-envelope model could work out cheaper. The feature gap — AI Assistant, scheduling, routing controls, approval workflows — is consistently in Inkfree's favor regardless of volume.
