SignNow vs Firma.dev
The predictable, SaaS-ready SignNow alternative
Predictable pricing and SaaS-ready e-signatures in hours, not weeks
Why SaaS Teams Choose Firma
SignNow delivers e-signatures. Firma delivers e-signatures as a service that SaaS companies can embed, package, and scale. With 60x lower cost, SaaS-ready architecture, and developer-first integration, Firma helps you turn e-signatures into a feature of your product — not just a tool you use.
Predictability vs. Complexity
The Cost Difference:
Predictability vs. Complexity
SignNow uses a signature invite model.
Sending a single document group to multiple recipients counts as one invite. But if you share a signing link that is opened multiple times — or forwarded without the right settings — you may be charged per open.
That means a single contract can generate multiple charges. Costs quickly become unpredictable, especially at scale.
Firma takes the opposite approach.
One envelope = one charge, no matter how many recipients, opens, or forwards. At €0.049 per envelope, you know exactly what you’ll spend.
Example: 1,000 documents sent per month
Firma: €49 total.
SignNow: €2,016+ (and possibly higher with extra document opens).
That’s a 40x cost savings every month.

Built for SaaS, Not Just Signatures
Key advantages for SaaS teams:
Tenant isolation: Separate customer workspaces for security.
Team-level analytics: Understand usage across customers.
Embedded editors: Allow users to create templates and sign documents inside your app.
Predictable pricing: Flat per-envelope model makes revenue planning straightforward.
Developer Speed: Hours, Not Weeks
SignNow provides a developer API, but setup and billing complexity slow down integration. Most teams treat it like a bolt-on tool. Firma was designed for developers who need to move fast:
Simple, well-documented API
Embedded template + signing editors (no need to build your own UI)
Pay-as-you-go model with no minimums or contracts
Most teams integrate Firma in hours, not weeks.
Comparison
Comparison at a Glance
Checked 25 July 2026. Every figure below comes from SignNow's own published API pricing page or documentation on that date. Entry-level plan against entry-level plan. No volume discounts, no enterprise pricing.
The per-invite arithmetic
SignNow's entry Professional plan is €84 a month annually for 500 signature invites a year. That is €1,008 a year, or €2.016 per invite.
At one signer per document, that is about 41x our price. At three signers, which is ordinary for anything involving a counterparty and a witness, the same document costs them €6.05 against our €0.049.
We do not charge for recipients, opens, forwards, reminders or resends. The envelope is the unit, and it is priced once.
I found Firma, and I think within two days of just messing around with the API, I was able to set up everything and have the communication between Firma to our LOS very, very quickly.

Where your documents actually live
This matters more than the price for anyone operating in the EU or the UK, and it is the hardest thing to find out from their marketing.
SignNow Has No EU Data Centre, Only a Data Transfer Agreement
We could not find a European data centre for SignNow. Its published position on EU data rests on participation in the EU-US Data Privacy Framework, which is a mechanism for transferring personal data out of the EU lawfully. It is not data residency. Your documents are not being kept in Europe, they are being moved out of it under an agreement.
Firma.dev Runs on EU Servers by Default
Firma.dev is EU-hosted as standard, on AWS in Paris with CloudFront in Stockholm. Not an upgrade, not a tier, not a configuration step at implementation. It is where your documents are.
If your customers ask where their signed contracts are stored, one of these answers is much shorter than the other.
A separate workspace for each of your customers
Workspaces let your application create an isolated environment for each of your own customers or business units, provisioned through the API. Each one has its own API key, its own templates and documents, its own envelope usage, its own branding and sending domain, and its own webhook secret. Nothing is shared between them.
SignNow Lacks Per-Workspace Isolation, Despite Offering Embedded Signing
This is not the same as embedded signing, which only places a signing screen inside your app. SignNow offers embedded signing on its entry paid API plan. What we could not find is per-workspace isolation with independent keys.
Creating a Workspace Is One API Call, With Keys and Billing Isolated Per Client
Creating one is a single call to POST /workspaces. Keys rotate per workspace, so revoking one customer's access never touches another's, and usage is counted per workspace so an agency can bill each client for their own envelopes without reconciling anything by hand.
