The real cost

What SignNow actually costs at moderate volume

The advertised price assumes you stay under 100 invites per user per year. Most teams don't.

SignNow Business Premium — 1 user, 45 docs/month

Advertised price $15/user/month

Annual sticker cost $180/year

Included invites/year 100

Invites needed (45/mo) 540/year

Overage invites 440 × $1.50

Overage charges ~$660

Actual cost: ~$840/year — vs the $180 on the pricing page. The cap is buried in FAQ fine print, not the pricing table.

CalmSign Pro

Monthly fee $12/month

Annual cost $144/year

Document cap None

Overage charges None

Surprise fees None

Actual cost (45 docs/mo) $144/year

Send 45 or 450 documents a month. The price is still $12. That's the entire pricing model.

Honest assessment

Where each tool wins

CalmSign is the better fit when…

You send documents every week and the 100-invite cap means you'll hit overages by mid-year
You want a pricing page where the number shown is the number charged — no FAQ excavation required
You need cryptographically sealed documents with a vendor-independent SHA-256 proof embedded in each one, backed by a full audit trail
API access matters and you don't want to pay $146+/month for a separate plan
You'd rather have a permanent verifiable record than depend on a vendor's ecosystem

SignNow is the better fit when…

Your volume is genuinely small and predictable — fewer than 8 documents per user per month, reliably, all year
You have a large team and need unlimited seats at a low per-user rate
You need native iOS and Android apps rather than a browser-based workflow
You're already invested in the airSlate workflow ecosystem

The 100-invite cap was added to all SignNow plans in 2025 and is described as "buried in the last FAQ at the bottom of the page" rather than disclosed on the pricing table. Some users have reported charges of $198+ on a $30/month subscription from hitting the cap without warning.

The verdict

Who should choose which

SignNow's sticker price wins if your volume is truly small and predictable — fewer than 8 documents per user per month, every month, no exceptions. In that case, $8/user/month is genuinely cheaper than $12/month flat.

CalmSign wins the moment your volume is anything but tiny and predictable. The 100-invite cap turns SignNow's advertised price into a floor, not a ceiling. If you send documents weekly, the sticker price is fiction — you'll be paying overages. CalmSign Pro at $12/month is the actual price: unlimited documents, no caps, no overage math, no surprise charges at renewal.

The simplest test: pick the tool whose price is the price.

Common questions

Is there a free alternative to SignNow?

Yes. CalmSign's free tier gives you 5 documents per month with full signing, audit trails, and document verification — no credit card or trial expiry. SignNow offers a 7-day free trial with no card, but no ongoing free tier.

What is SignNow's 100 invite limit?

In 2025, SignNow changed all standard plans to cap each user at 100 signature invites per year. Sending more than 100 documents triggers per-invite overage fees of $1.50–$1.80 depending on your plan. This cap is disclosed in FAQ fine print, not on the main pricing page.

How much do SignNow overages cost?

SignNow charges $1.50–$1.80 per signature invite over the 100/year cap, depending on your plan tier. An HR team sending 45 documents per month would pay roughly $660 in overages (at $1.50/invite) on top of the $180 annual subscription — around $840/year total.

Does CalmSign have a document cap?

No. CalmSign Pro at $12/month and Business at $29/month have no document or signature caps. The free tier is limited to 5 documents per month. There are no overage charges on any plan.

Is CalmSign cheaper than SignNow for regular use?

For very low volume (fewer than 8 documents per user per month, consistently), SignNow's $8/user/month advertised price is cheaper. For anyone who sends documents every week, CalmSign Pro's $12/month flat fee will be cheaper once you account for SignNow's overage charges.

Does CalmSign have a mobile app like SignNow?

CalmSign is browser-based — it works on any device without a dedicated app. SignNow does offer native iOS and Android apps. If a native mobile app is a hard requirement, that's a genuine advantage for SignNow.
