Welcome to Pacta
A quick orientation to Pacta — what it is, who it's for, and where to go next.
Last updated May 12, 2026
Pacta is the document signing platform built for teams that take agreements seriously. Send, sign, and seal contracts with eIDAS-grade cryptographic signatures, immutable audit trails, and the compliance posture your auditors will sign off on — without the legacy enterprise sticker shock.
Three personas, one product
Most teams using Pacta fall into one of three roles:
- Senders — the people who create and send documents for signature (sales, legal, ops). They upload PDFs, add fields, pick recipients, and hit send.
- Signers — the people who receive a Pacta email and sign a document. They don’t need a Pacta account; they sign and walk away with a verified PDF in their inbox.
- Admins — the org operator. They invite teammates, manage branding, configure email domains, and watch billing.
The rest of this guide is organized so each persona can jump straight to what they need.
Where to go next
- First time sending? → Send your first document
- Received an email asking you to sign? → Sign a document you received
- Setting up your team’s workspace? → Set up your organisation
- Comparing plans? → Choose a plan
What makes Pacta different
Most e-signature tools were built for paper-based workflows moved online. Pacta was built for the next decade — cryptographic, AI-native, and engineered for the industries where contracts actually carry weight.
The shortest version of the pitch:
- Cryptographic, not just legal. Every signature is a CAdES / PKCS#7 envelope, not a JPEG of a name. With Time Stamp Authority + Long-Term Validation, signatures stay verifiable for decades.
- Built for regulated industries. Fintech, healthcare, anything under CFR21 Part 11 or HIPAA. Compliance flags ship in the box.
- AI that drafts the doc. Plain-English contract drafting, auto field placement, clause Q&A for signers. (Pro & Business)
- Mobile-first create-and-send. Native iOS app shipping Q4 2026. Voice + camera + AI to send a contract from your phone.
- Public code, hosted convenience. The Pacta platform is AGPL on GitHub. Self-audit it, run it yourself, or just let us host it.
