The answer, as recorded

## My picks, in the order I'd actually suggest them **1. Dropbox Sign** (formerly HelloSign) - my default for most startups. Cleanest signing UX of the mainstream options, genuinely good API with sandbox + good docs, and roughly $15-20/mo for a single user, ~$17.50/user/mo on Standard. The catch is template limits on cheap plans (5 on Essentials, 15 on Standard), which bites once you're sending repeat offer letters and NDAs. ([pricing comparison](https://www.stackscored.com/pricing/e-signature/compare/dropbox-sign-vs-pandadoc/), [vs DocuSign](https://casrai.org/guides/dropbox-sign-vs-docusign)) **2. SignNow** - the value play. ~$8/user/mo annually on Business, and unlimited users on paid plans, so it's the cheapest way to get a whole team signing without per-seat pain. Less polished than Dropbox Sign; fine if signing is a cost center, not part of your product. ([source](https://www.signnow.com/blog/best-electronic-signature-app/)) **3. PandaDoc** - pick this if you're *selling*, not just signing. ~$19/user/mo Starter, $49 Business. It's really proposal/quote software with signing attached: templates, pricing tables, analytics on who opened what. Also has a free e-sign tier with no envelope cap, which is unusual. Overkill if you only need HR and vendor paperwork. ([source](https://costbench.com/software/e-signature/pandadoc-sign/)) **4. DocuSign** - the one nobody will question. ~$30/user/mo on Standard annually (more month-to-month), plus fees for SMS delivery and ID verification. Worth it specifically if you're signing with enterprises, banks, or law firms whose counsel expects DocuSign, or you need heavy compliance (21 CFR Part 11, qualified EU signatures). Otherwise you're paying a brand premium. ([source](https://dupple.com/learn/docusign-alternatives)) **5. Zoho Sign** - best free tier to start on, at 5 envelopes/month for 1 user, $10/user/mo for Standard (25 envelopes/user/mo). Obvious choice if you're already in Zoho; the free plan does put Zoho branding on your docs, which looks cheap on an offer letter. ([source](https://costbench.com/software/e-signature/zoho-sign/free-plan/)) **6. Documenso** - open source, self-hostable, ~12k GitHub stars, real PAdES-compliant signatures, webhooks, free for unlimited senders. Choose this only if signing is a feature of your product and per-envelope pricing would eat your margin, or you have a data-residency requirement. You're taking on ops work in exchange. ([source](https://livemy.app/blog/self-host-documenso)) **Also worth a look:** SignWell if you want cheap-and-simple without the self-hosting; Adobe Acrobat Sign if your workflow is already PDF-heavy in Acrobat. ## What I'd actually do If you're pre-seed and signing <10 docs/month: start on Zoho Sign or PandaDoc's free tier, spend nothing. If you have a team and real contract volume: Dropbox Sign. If e-signature is going *inside* your product: Dropbox Sign's API, or Documenso if the unit economics demand it. One caveat on the numbers above: they come from comparison/aggregator sites of uneven quality, and e-sign vendors change pricing and repackage tiers often. Confirm on the vendor's own pricing page before you commit, and check envelope and template caps specifically - that's where the advertised price stops matching the bill.
