DollarSign.io — pay-as-you-go electronic signatures

The cheapest way to get a contract signed online

Last updated September 12, 2026

There is no single cheapest option — there is a volume at which the answer changes. Work out roughly how many documents you send in a year and the rest is arithmetic.

The short version. Under roughly twenty documents a month, paying per document wins on price and it is not close — and against DocuSign's capped plans it keeps winning well past that. Above twenty a month an unlimited subscription starts to cost less, and you are usually buying workflow features by then anyway.

Start with the annual number

Subscriptions are priced per year. Per-document services are priced per document. To compare them you need one number: how many documents you will send for signature in the next twelve months. Be honest rather than aspirational — most people overestimate this considerably.

What a year costs, by volume

Per yearDocuSign PersonalDocuSign StandardAdobe Acrobat Pro$1.00 per envelope
1$132$360$239.88$1.00
6$132$360$239.88$6.00
12$132$360$239.88$12.00
24$132$360$239.88$24.00
60$132 (at the cap)$360$239.88$60.00
100not possible$360 (at the cap)$239.88$100.00
250not possible$1,080 (3 seats)$239.88$250.00

Annual-commitment pricing. DocuSign Personal allows 5 envelopes a month; Standard allows 100 per user per year, so higher volumes need more seats.

Prices read from DocuSign and Adobe in September 2026. Adobe's page states no signature limit; the others cap explicitly.

Where the lines actually cross

Against DocuSign Personal at $132 a year, per-envelope pricing stays cheaper until 132 documents — but the plan only permits 60, so per-document is cheaper at every volume Personal allows, and by a wide margin. At its own ceiling Personal works out to $2.20 a document; this is $1.00.

Against DocuSign Standard the caps do the work. Past 100 documents a year you are buying additional seats at $360 each, so at 250 documents Standard costs $1,080 against $250.00 per-envelope. Capped subscriptions stop behaving like bulk discounts the moment you exceed the cap.

Adobe Acrobat Pro is the one that eventually wins. At $239.88 a year with no signature limit stated on its pricing page, the crossover is around 240 documents a year — about twenty a month. Below that, per-document is cheaper. Above it, Adobe is, and we would rather say so than pretend otherwise.

So the honest rule of thumb: roughly twenty documents a month is where an uncapped subscription starts winning on price. Against a capped one, per-document stays cheaper much further out. Either way, once you are sending that often you want templates and a dashboard — buy those deliberately rather than squeezing another year out of the cheapest line item.

The free options, and what they cost you

Print, sign, scan

Free if you already own a printer and a scanner. What you lose is the audit trail — a scanned signature has no record of who signed, when, from where, or whether they saw every page. For anything that might be questioned later, this is the weakest option available, not the cheapest.

Free trials

Genuinely free for one document if you cancel. Set the reminder when you sign up, not later. The failure mode is an annual charge you did not plan for.

Free tiers

Permanent but bounded — usually a few documents a month. Check two things before committing: whether you get a real audit certificate, and whether the signing page carries the provider's branding. For a friendly agreement neither matters. For a contract with money in it, both do.

Typing a name into a Word file

Worth saying plainly: an electronic signature is legally valid, but only when the record shows the signer consented, reviewed, and intended to sign. A typed name in a document nobody can prove was reviewed carries almost none of that. What the law actually requires.

Do not choose on price alone

Four questions that matter more than a few dollars:

If you are at the low-volume end. DollarSign.io is $1.00 per envelope, flat — up to 10 signers and 100 pages, no account, no subscription. Every completed document comes with a Certificate of Completion and a SHA-256 fingerprint, and stays retrievable indefinitely. Upload a document to see the whole thing before paying.
