The Nearly Free Electronic Signature API That Just Works

Most electronic signature platforms are overpriced. Whether you’re a SaaS startup or scaling product team, paying $1–$5 per envelope quickly crushes margins. Add in monthly minimums, hidden fees, and long-term contracts, and electronic signatures start to look like a luxury feature instead of a basic requirement.

Firma changes that. At $0.029 per envelope with no minimums, no contracts, and no seat-based pricing, Firma is the nearly free electronic signature API. It’s fully featured, legally valid in the U.S. and EU, and built for developers who want integration in hours—not weeks.

Why Electronic Signatures Are So Expensive

Most providers price electronic signatures like enterprise software:

• DocuSign: Typically $1+ per envelope, plus required monthly plans.

• Adobe Sign: Similar structure, per-seat licensing, with volume tiers.

• Others: Often hide API access behind higher subscription levels.

The result: SaaS apps that want to embed e-signatures into their workflow face cost structures designed for Fortune 500 procurement teams. For product managers and developers, that’s a dealbreaker.

Firma’s Model — Pay as You Go, Nearly Free

Firma flips the model with one simple principle: pay only for what you use.

• Flat $0.029 per envelope (2.9¢ USD)

• No upfront fees

• No monthly minimums

• No seat-based licensing

For perspective:

• 10,000 envelopes with Firma = $290

• 10,000 envelopes with DocuSign = $10,000+

That’s a 98%+ savings. Enough to protect your margins and open up use cases that competitors make impossible.

• Integration in hours, not weeks

• Clear docs: Get started with Firma Docs

You focus on your product. Firma handles infrastructure, scaling, and compliance.

Legal Validity Across the U.S. and EU

Adding electronic signatures to your product isn’t just about UX. You need legal enforceability and data protection:

• U.S.: ESIGN Act, UETA, HIPAA, FDA 21 CFR Part 11

• EU/UK: eIDAS (SES, AdES), GDPR

• Security: Built around SOC 2 Trust Services Criteria and ISO/IEC 27001 standards

Firma aligns with these frameworks, so you can embed signatures without legal gaps.

Customer Workspaces

Every customer you onboard gets a private workspace:

• Partitioned templates and documents

• Isolated envelope usage tracking

• No cross-customer exposure

This gives SaaS platforms clean, secure separation—without complicated “tenant” setups.

What “Nearly Free” Unlocks

When electronic signatures cost pennies instead of dollars:

• SaaS apps can include e-signatures in free tiers

• Product teams can scale usage without margin fear

• Developers can ship legally valid features without being blocked by cost or contracts

This is why product managers choose Firma over legacy platforms.

Conclusion

Firma is the first nearly free electronic signature API that combines affordability, developer speed, and global legal validity. No seat-based pricing, no contracts, no friction.
