Price ranges by tool, confirmed live

I checked every price below directly on the vendor's own pricing page on 2026-10-31. These are current, not carried over from an older comparison post.

• QuickSigner, an e-signature platform for sending and collecting legally binding signatures from any device: Personal is free (5 documents a month, up to 3 signers, 5 MB file size limit). Business runs $5 a user a month, or $48 a year on annual billing, with unlimited documents, up to 10 signers and 10 templates. Professional runs $15 a user a month, or $144 a year, with up to 50 signers and API access included.
• SignWell, built around unlimited signing requests with no per-document fees: free for 3 documents a month, then roughly $10 to $12 a month for its Light plan with unlimited documents.
• DocuSign, the most recognized dedicated e-signature brand: $11 a month on a yearly plan for Personal (5 envelopes a month), rising to $30 and $45 a user a month for Standard and Business Pro.
• PandaDoc, really a proposal and document tool with signing built in: free for 5 documents a month, then $19 a seat a month for Starter and $49 a seat a month for Business, plus usage credits for API calls and bulk sending.
• Zoho Sign, built by Zoho and tightly connected to its other business apps: free for 1 user and 5 envelopes a month, with Standard, Professional and Enterprise tiers priced per user per month above that. Zoho's own pricing page loads exact dollar figures through a currency selector that didn't resolve to a visible number for me live, so confirm the current one directly on Zoho's page.
• Adobe Acrobat, where e-signing is bundled into the regular PDF editor rather than sold on its own: individual plans ran £14.99 to £24.98 a month on the page I checked, and Acrobat Pro for Teams listed at $28.98 a user a month in the US on an annual plan. Cheaper routes are in Adobe Acrobat Sign pricing and cheaper options.
• Dropbox Sign, the signing tool built into the Dropbox ecosystem: starts at $15 a user a month billed yearly, with its API starting at $75 for 50 requests a month.

Annual billing almost always beats monthly, by more than you'd expect

Every tool above offers a meaningful discount for paying annually rather than monthly, and it's worth actually running the math before defaulting to monthly out of caution. SignWell's Light plan, for instance, runs roughly $10 a month on annual billing versus $12 a month billed monthly, a 20% difference that adds up to about $24 a year. QuickSigner's Business plan runs $48 a year annually versus $60 a year if paid monthly at $5 a month, the same roughly 20% gap. None of these discounts require a long-term contract you can't get out of, SignWell explicitly advertises no long-term contracts regardless of billing term, so the usual risk of annual billing, being stuck if the tool doesn't work out, is lower here than it is for some software categories. If you're confident you'll use the tool past the first month, which is likely given how low the entry cost already is, annual billing is close to free money.

Cost per signed document, not just per month

The monthly sticker price only tells half the story, because plans cap how much you can actually send. Here's the real cost per document at each tool's lowest paid tier, assuming you send right up to the cap:

• QuickSigner Business ($5 a month, unlimited documents): effectively $0 a document once you're past a handful a month, since there's no document cap at all on this tier.
• SignWell Light (around $10 to $12 a month, unlimited documents): same story, cost per document drops toward zero as volume rises.
• DocuSign Personal ($11 a month, 5 envelopes): $2.20 per envelope if you use the full allowance, rising sharply per document if you send fewer.
• PandaDoc Starter ($19 a seat a month, unlimited documents, but API use needs paid credits): effectively free per document for standard sending, with a separate, uncapped cost if you automate sending through the API.

The pattern here is clear: tools with a flat price and an unlimited or high document ceiling (QuickSigner, SignWell, PandaDoc for manual sending) get cheaper per document as your volume rises. Tools priced by envelope or request (DocuSign at the entry tier, any API usage) get more expensive the more you actually use them, which matters a lot if your volume is genuinely variable month to month.

The hidden costs that actually catch people out

None of the surprises below are secret, they're disclosed on every vendor's pricing page, but they're easy to miss when you're comparing headline prices side by side.

• Extra signers per document: QuickSigner's Business plan caps you at 10 signers per document, and Professional raises that to 50. If you regularly need more signers on a single contract than your tier allows, you'll need to upgrade regardless of how many documents you're sending.
• API pricing kicks in fast: QuickSigner charges $0.30 per sign request through its API once you're past the first 50 free requests a month on Professional. Dropbox Sign's API starts at $75 for just 50 requests a month, a meaningfully steeper entry point. If you're planning to trigger signing automatically from another system rather than sending manually, price the API tier specifically, not the manual-sending tier.
• Template limits on lower tiers: QuickSigner's Business plan includes 10 templates; SignWell's Light plan includes 5 templates per sender. If your business runs more than a handful of distinct contract types, you'll hit this limit before you hit a document-volume limit.
• Extra senders and seats: adding a second person who needs to send documents, not just sign them, usually costs more per month on every tool here. SignWell charges roughly $10 to $15 a month per additional sender depending on plan and billing term.
• File size caps: QuickSigner's Personal tier caps files at 5 MB, rising to 10 MB on Business and 15 MB on Professional. A multi-page contract with embedded images or scanned exhibits can hit this faster than you'd expect.

A worked example: a 6-person agency sending 80 contracts a month

Take a small agency with 6 people who each occasionally need to send a contract, totaling 80 documents a month, with up to 5 signers on the biggest ones. On QuickSigner's Business plan, that's $5 a user a month, so roughly $30 a month total for all 6 seats, with unlimited documents and room to spare on the 10-signer cap. On DocuSign Standard at $30 a user a month, the same 6 seats cost $180 a month, nearly six times as much, even though the 100-envelopes-a-user-a-year allowance comfortably covers 80 documents split across the team. The difference isn't features at this volume, it's that DocuSign's per-seat price is built for a different kind of buyer than a lean agency sending a moderate, steady volume. If a different tool suits you better, see QuickSigner alternatives.

How I'd approach this

When a client asks me to help pick an e-signature tool as part of a bigger project, I start by asking them to actually count last month's signing volume, not guess it, since the gap between "we send a few contracts" and the real number is usually bigger than people expect in either direction. Then I match that number against each tool's actual caps, not its marketing tier names, because "Business" or "Professional" means something different on every vendor's page. The mistake I see most is businesses defaulting to the name they've heard of, DocuSign or Adobe, and paying three to six times what a less familiar but equally legitimate tool would cost for the same real volume.

Need something completely custom?

Everything above is a path to get it running quick and cheap. But sometimes the honest answer is that none of those quite fit, and what you actually need is something custom that you own, built uniquely for your business from the ground up, with AI thoughtfully designed into the parts of it that your processes actually benefit from. An asset that grows in value, not a generic, one-size-fits-all boilerplate that's an expense with a lock-in. This is a complete bespoke build, and it's something I do very well.
