↗ · Cheapest e-signature software

The cheapest e-signature software, ranked by cost per signed document.

Sticker price hides the real number. A $10 plan with 5 envelopes costs $2 a document; a $12 plan with 1,000 submissions costs under 2 cents. Here's the 2026 math, done honestly, with the cases where paying more is correct.

↗ · The alternatives

The cheapest e-signature tool isn't the one with the lowest monthly price, it's the one whose meter fits your volume. We ranked these five by effective cost per signed document on their entry tiers, and the order surprises people: the cheapest-looking plan on the list, DocuSign Personal at $10, comes out the most expensive per document.

01Sign SailThat's us

Free 25/mo · Pro $12/mo for 1,000/mo, ≈1.2¢ each

Best for: Lowest cost per signed document at any real volume

Pro at $12/mo billed annually includes 1,000 submissions a month, each able to carry a legally binding signature with the SHA-256 audit trail, which works out to under 2 cents per signed document at full use. Below 25 a month you pay nothing at all. Pricing is flat per account, never per seat or per envelope, so the math doesn't change when you add volume or teammates. What you don't get at this price: EU Qualified Signatures, notarization, or contract lifecycle management.

02SignNow

From ~$8/user/mo billed annually

Best for: Cheapest per-seat price for teams sending simple contracts

The lowest per-seat sticker in the category, with templates, bulk send, and a basic API on affordable tiers. The interface is utilitarian, and per-seat pricing means the bill scales with headcount rather than volume. Sensible when many people send straightforward contracts and the per-seat math still beats flat-priced tools.

03SignWell

Free 3 docs/mo · paid from ~$10/mo

Best for: Cheapest single-user plan for finished contracts

Around $10 a month for a clean, no-frills signing tool, with a free tier of 3 documents a month to start on. No form builder or data export, so the documents arrive finished and leave signed, nothing more. For one person sending contracts at modest volume, this is the budget benchmark.

04OpenSign

$0 software, self-hosted; you pay hosting and upkeep

Best for: Cheapest at scale, if your time is free

Open source and self-hosted, so the per-document cost trends toward your server bill divided by your volume. The honest accounting includes the hours: deployment, storage, upgrades, and being the person who gets paged. Cheapest on paper, cheapest in practice only for teams that already run infrastructure.

05DocuSign (Personal)

$10/mo, 5 envelopes/mo, about $2 per envelope

Best for: The familiar brand at genuinely low volume

Included because everyone asks. At $10 a month for 5 envelopes, each send costs about $2, the highest per-document price on this list, and an envelope counts when sent whether or not it's signed. If you send 3 contracts a month and your counterparties expect the DocuSign brand, it's defensible. At waiver or intake volume, the math is the reason the rest of this page exists.

↗ · Fair is fair

When a pricier tool is the better pick.

You need EU Qualified Electronic Signatures, notarization, or identity verification. That high-compliance tier is precisely what the expensive platforms charge for, and none of the budget tools here, ours included, offer it.
Your legal team wants contract lifecycle management: clause libraries, approval chains, redlining, renewals. Cheap e-signature tools sign documents; they don't manage a contract's life.
Procurement requires an enterprise compliance package, custom DPAs, security reviews, and named account management. At that point the price buys the paperwork and the support, not just the signing.

↗ · Questions

Asked before you switch.

What's the cheapest way to get a document legally signed online?

Free, at low volume. Sign Sail's free plan covers 25 signed submissions a month with a full SHA-256 audit trail; SignWell and Dropbox Sign cover 3 documents a month. Past the free caps, Sign Sail Pro at $12/mo billed annually for 1,000 monthly submissions is the lowest per-document price among hosted tools, under 2 cents each.

Why does DocuSign get expensive for small businesses?

Envelope metering. The Standard plan costs $25 per user per month and includes 100 envelopes per user per year, about $3 per envelope, and an envelope is consumed when sent, signed or not. Form-shaped workflows, waivers, intake, registrations, burn through envelopes fast, which is why volume senders end up on submission-metered or flat-priced tools.

Is cheap e-signature software still legally binding?

Yes. ESIGN, UETA, and eIDAS Simple Electronic Signature compliance is table stakes across every tool on this list. Price buys volume, features, and support, not legality. Sign Sail's cheapest tier, the free one, carries the same signer IP, timestamp, SHA-256 hash, and PAdES-sealed PDF as its paid plans.

How should I compare e-signature pricing between tools?

Divide the monthly price by the documents you'll actually send, and check three multipliers: per-seat pricing (the bill scales with headcount), per-envelope metering (the bill scales with sends, including unsigned ones), and overage behavior. A flat plan with a generous meter is almost always cheapest for recurring volume; a low sticker with a tight meter is cheapest only at trivial volume.

Legal-grade on every plan.

Every signature carries the signer's IP, a UTC timestamp, the user-agent, a SHA-256 hash, and a frozen copy of the form, baked into a signed PDF. Included at every tier, not sold back to you as an upgrade.
