The answer, as recorded

## My shortlist for a startup **1. Dropbox Sign** (formerly HelloSign) - my default recommendation for most startups. Cleanest signing UX of the major players, unlimited signature requests even on the entry plan (~$15/mo), and a genuinely good, well-documented API if you ever need to embed signing in your product. The one gotcha: the Standard tier has a two-seat minimum, so it jumps to ~$50/mo when you outgrow solo use. ([pricing comparison](https://www.stackscored.com/pricing/e-signature/compare/dropbox-sign-vs-pandadoc/)) **2. PandaDoc** - pick this instead if your signing is attached to *selling*. It's a proposal/quote/contract builder that happens to include e-signature, with templates, pricing tables, and analytics on who read what. Starter runs ~$19/user/mo annual, Business ~$49. Overkill if you just need to countersign NDAs and offer letters. ([pandadoc.com](https://www.pandadoc.com/blog/docusign-alternatives/)) **3. SignWell** - the best cheap option. Free tier covers 3 documents/month, which is honestly enough for a pre-seed company doing a handful of contractor agreements. Paid tiers are inexpensive and the API has a pay-as-you-go model (~25 free docs/month, then per-document pricing) rather than forcing you onto an enterprise seat. ([signwell.com](https://www.signwell.com/resources/best-esignature-api/)) **4. Zoho Sign** - only if you're already on Zoho. ~$12-22/user/mo and it slots into the rest of the suite nicely. Be aware API access is gated behind the Enterprise tier, which kills it as a developer-first choice. ([zoho sign api review](https://www.signwell.com/resources/zoho-sign-api/)) **5. Documenso** (or DocuSeal) - open source, self-hostable, free at unlimited volume. Worth it if you have data-residency requirements, want signing inside your own product without per-envelope costs, or just have an engineer who'd rather run a container than pay a SaaS bill. You're trading money for maintenance. ([comparison](https://signb.ee/blog/best-e-signature-apis-developers-2026)) **6. DocuSign** - the name everyone recognizes, and that's the actual reason to use it: enterprise counterparties and law firms trust the brand, and nobody questions the audit trail. But it's the worst value for a small team - the cheap plans cap you at ~5 envelopes/month (Personal) or ~100/year (Standard), with $3-8 per-envelope overages after that. ([docusign pricing](https://www.pandadoc.com/blog/docusign-pricing/)) ## What I'd actually do Start on **SignWell's free tier** while volume is low, move to **Dropbox Sign** when you're signing regularly, and only add **PandaDoc** if a sales team shows up. The underlying legal validity (ESIGN/UETA in the US, eIDAS in the EU) is equivalent across all of these - you're choosing on workflow, price structure, and whether your counterparties care about the logo on the email. Two things worth checking before you commit: whether pricing is per-*seat* or per-*envelope* (that's what bites startups as they grow), and whether the vendor charges extra for the API, since embedding signing later is a common need and retrofitting a migration is annoying. One caveat on the numbers above: several of these came from vendor-run comparison blogs, and e-signature pricing changes often - verify current rates on each vendor's own pricing page before you buy.
