SignNow vs Sign.Plus

Most teams running this comparison have already ruled out DocuSign on cost and now need to choose between two genuinely different value propositions. SignNow looks cheaper on paper — $8 vs $19.99 — but the comparison only holds if your team's annual invite volume stays under 100. Sign.Plus looks more expensive per seat, but its unlimited-request model becomes cheaper above ~120 invites/year for a single user, and the gap widens fast at higher volumes.

The deeper question is geography and compliance posture. If you're a European business — especially Swiss, German, or French — Sign.Plus's eIDAS Qualified Electronic Signature and ZertES support are unique at this price point and can settle a procurement decision on their own. If you're a US healthcare or life-sciences team needing HIPAA and 21 CFR Part 11, SignNow's Site License tier covers it. Most teams choose by where their compliance pressure is, then verify the volume math fits.

SignNow's strengths come from its unusual unit economics:

• Cheapest entry point with multi-user teams. A five-person team on SignNow Business pays $8/month total — about $96/year. The same team on Sign.Plus Professional pays $19.99 × 5 × 12 ≈ $1,200/year. As long as the team's annual invite volume stays under 100, SignNow saves the team well over $1,000/year. For internal HR signing, NDA workflows, or low-volume operational signing, this is decisive.
• Pay-per-invite Site License at extreme volume. Sign.Plus's per-user model breaks down for teams sending thousands of invites a year — at 5,000 invites/year on Sign.Plus Business across 10 users, you pay $29.99 × 10 × 12 = $3,599/year. The same volume on SignNow Site License is $1.50 × 5,000 = $7,500/year — more, until you add more users. At 25 users sending 5,000 invites/year, Sign.Plus runs $8,997/year vs SignNow Site License's flat $7,500. Site License's economics flip in SignNow's favor for high-volume, larger teams.
• HIPAA and 21 CFR Part 11 on Site License. US-regulated industries (healthcare BAA workflows, FDA-regulated electronic records) get covered on SignNow's Site License tier. Sign.Plus only offers HIPAA + BAA on its Enterprise tier (~$49.99/user/month), and lacks 21 CFR Part 11 in the standard documentation — a real gap for life sciences buyers.
• Standard Salesforce / NetSuite integration. SignNow Site License ships official CRM connectors. Sign.Plus's Salesforce integration is officially marked as "under development" on the vendor's integrations page — meaning sales teams that depend on Salesforce-native eSignature should default to SignNow.

Sign.Plus wins decisively on three fronts where SignNow is structurally weaker:

• Truly unlimited signature requests. Once you cross ~100 invites/year, SignNow forces you to either upgrade to Site License (pay-per-invite) or accept overages. Sign.Plus Professional at $19.99/user/month gives you actual unlimited requests — no cap, no overage anxiety. For a solo freelancer or two-person consultancy that sends contracts steadily, this is the cleaner mental model.
• EU compliance ceiling that SignNow cannot reach. Sign.Plus uniquely includes eIDAS Qualified Electronic Signatures (QES) on every plan including Free — the highest tier of eIDAS, equivalent to a notarized handwritten signature in EU law — and ZertES, the Swiss federal qualified-signature regime, also on every plan. SignNow offers eIDAS Advanced Electronic Signatures (AES) via an add-on at best, and no native ZertES. For European legal, banking, or government-adjacent contracts, this isn't a feature gap — it's a compliance gap.
• Modern UX and developer experience. Both platforms are well-designed, but Sign.Plus is consistently rated as having the cleaner interface — recipients almost never report friction during signing. The REST API is documented and available on standard tiers; SignNow's API requires Site License. For dev-led teams building signing into their own product on a standard plan budget, Sign.Plus is the better choice.
• Bundled Scan.Plus Pro. Personal plans and above include Sign.Plus's mobile document scanner at no extra charge — a small but legitimately useful add-on for mobile-first workflows where you need to capture a paper document, scan it, and send it for signature. SignNow has no equivalent in the box.

The trade-off most buyers miss is how the two pricing models punish you when your team grows out of its plan. On SignNow, growth means hitting the 100-invite cap and being forced into Site License's pay-per-invite math — a discontinuous price jump. On Sign.Plus, growth means adding seats at $19.99 each, a smooth linear cost. Most teams underestimate how much friction the SignNow cliff creates: when the workspace hits 99 invites, every additional signature becomes a budget conversation. With Sign.Plus, growth feels predictable. The other side: if your team genuinely caps at 5 people sending 50 contracts a year, SignNow's flat-rate model is dramatically cheaper and the cliff never matters. Pick the model that matches your actual growth trajectory, not the one that looks cheapest at the entry point.
