Legally binding signatures. No per-document fees. Your data on your infrastructure.
Every business signs documents - contracts, NDAs, onboarding forms, employment agreements, supplier terms. Commercial e-signature platforms charge per envelope or per user, and your signed documents live on their servers. DocuSeal is the open source alternative: the same legally compliant electronic signature capability, self-hosted on infrastructure you control, with a fixed operational cost regardless of how many documents you sign. Node deploys, operates and supports DocuSeal as a fully managed service.
What DocuSeal is and why it matters
DocuSeal is an open source electronic signature and document management platform that provides everything a business needs to send, sign and manage documents digitally. It handles the full document signing lifecycle - uploading or generating documents from templates, defining signing fields, routing documents to multiple parties in sequence or in parallel, capturing legally valid electronic signatures, and storing completed documents with a full audit trail.
The case for self-hosted document signing is straightforward. Platforms like DocuSign and Adobe Sign charge per envelope, per user or per transaction. For businesses with moderate to high document volumes - financial services firms processing client agreements, HR teams running onboarding workflows, legal departments managing supplier contracts - these costs accumulate significantly. DocuSeal eliminates per-transaction pricing entirely. Your cost is fixed infrastructure, regardless of volume.
Beyond cost, self-hosting means your documents never leave your infrastructure boundary. Signed contracts, employment agreements and NDAs contain sensitive information. With DocuSeal hosted on your own environment, that data stays on your servers, subject to your retention policies, accessible only to your team.
Document templates and field configuration
The foundation of an efficient signing workflow is a well-configured document template.
Template builder - DocuSeal includes a visual template builder where you define the fields that signers must complete: signature fields, initials, dates, text inputs, checkboxes, dropdowns and radio buttons. Fields are positioned visually on the document, assigned to specific signers and marked as required or optional.
PDF upload and generation - upload existing PDF documents to turn them into signing templates, or generate documents dynamically via the API with data merged into template placeholders. A contract template can be populated with a client name, address and commercial terms before being sent for signature, eliminating manual document preparation.
Multi-page documents - templates support documents of any length. Fields can be placed on any page, and DocuSeal tracks completion across the entire document. Signers are guided through each required field in sequence, reducing incomplete submissions.
Template reuse - once a template is configured, it can be used to generate signing requests indefinitely without reconfiguration. Standard agreements, NDA packs and onboarding document sets become one-click workflows.
Multi-party signing workflows
Most business documents require more than one signature, and the order in which parties sign often matters.
Sequential signing - configure signing order so each party receives the document only after the previous party has completed their fields. A contract might require the client to sign before the account manager countersigns. DocuSeal enforces this sequence automatically.
Parallel signing - send a document to multiple parties simultaneously when order does not matter. Each recipient receives their own signing link and completes their fields independently. The document is finalised once all parties have signed.
Role-based routing - define roles in a template (Client, Witness, Authorised Signatory) and assign real people to those roles at the point of sending. The same template handles any combination of parties without reconfiguration.
Reminders and expiry - DocuSeal automatically sends reminder notifications to signers who have not completed their fields within a configured timeframe. Signing requests can be set to expire, preventing indefinitely open documents from remaining in the system.
Signer authentication and identity assurance
Confirming that the person signing is who they claim to be is central to the legal validity of an electronic signature.
Email verification - every signing link is unique and single-use, sent to the signer's verified email address. Access to the signing link demonstrates control of the email account associated with the signer's identity.
SMS one-time passcode - for higher-assurance signing scenarios, DocuSeal supports SMS OTP verification. The signer must enter a code sent to a confirmed mobile number before they can access the document, providing a second factor of identity verification.
Keycloak integration - for internal documents signed by employees or authenticated users, DocuSeal integrates with Keycloak to require full SSO authentication before accessing signing workflows. Users must be logged in through your identity provider, providing the highest level of identity assurance for internal signing scenarios.
Drawn and typed signatures - signers can draw their signature, type it in a chosen font, or upload an image of their signature. All signature types are captured with the same legal weight under UK, EU and US electronic signature legislation.
Legal compliance and audit trail
Electronic signatures are legally binding under the UK Electronic Communications Act 2000, the EU eIDAS Regulation and the US ESIGN Act, provided the signature process meets defined requirements around intent, consent and record-keeping. DocuSeal is designed to satisfy these requirements.
Comprehensive audit trail - every event in the document lifecycle is recorded: when the document was created, when the signing request was sent, when each signer accessed the document, which fields they completed and when, and when the final signed document was generated. This audit trail is embedded in the completed PDF as metadata and stored separately as a tamper-evident log.
Timestamping - all signature events are timestamped with the signer's IP address, browser user agent and geographic location. This information forms part of the legal record and supports non-repudiation - the ability to demonstrate that a specific person signed at a specific time.
Completed document integrity - once all parties have signed, DocuSeal generates a sealed PDF with digital signatures embedded. Any subsequent modification to the document invalidates the digital signatures, making tampering detectable.
Retention and access control - configure document retention periods to match your legal and regulatory obligations. Access to signed documents is role-controlled, and all access events are logged. Your compliance team has full visibility of who accessed which documents and when.
API and workflow integration
DocuSeal is built for integration into existing business processes rather than requiring manual document handling.
REST API - every DocuSeal function is available via a documented REST API. Your application can create signing requests, populate template fields, track signing status, receive completed documents and trigger downstream actions programmatically. Signing workflows become an embedded part of your onboarding, contracting or procurement processes rather than a separate manual step.
Webhooks - real-time webhook notifications fire when documents are sent, viewed, partially signed and completed. Your systems receive immediate notification of signing events without polling, enabling instant downstream actions: CRM record updates, provisioning workflows, payment triggers and notification emails.
Embedded signing - the signing experience can be embedded directly into your own web application via an iframe. Your users sign documents without leaving your product, maintaining a seamless experience with no visible third-party platform.
Zapier and n8n integration - for teams using workflow automation tools, DocuSeal integrates with Zapier and n8n, allowing document signing events to trigger actions in hundreds of connected applications without custom development.
Hosted and managed by Node - deployed anywhere
We provide DocuSeal as a fully managed service. We handle deployment, configuration, upgrades, monitoring, backup and incident response. Your team uses document signing as a service without managing the underlying infrastructure.
Our infrastructure - hosted on Node's own high-availability platform with SLA-backed uptime, proactive monitoring and regular security patching. Your documents are encrypted at rest and in transit.
AWS, Azure or Google Cloud - deployed into your cloud tenancy using infrastructure-as-code, running on managed container services with cloud-native storage and database backends.
On-premise - deployed onto your own hardware or virtualisation platform for organisations with data residency, air-gap or regulatory requirements around where signed documents are stored.
Regardless of deployment model, we manage it. Same tooling, same monitoring, same support.
The case for open source e-signatures - DocuSign charges from £8 per user per month on entry plans, with per-envelope fees on higher volumes. Adobe Sign pricing is comparable. For a business sending 200 documents per month across a team of 10, commercial platform costs run to thousands of pounds annually - and escalate as your business grows. DocuSeal provides the same legally compliant electronic signature capability as a self-hosted service with a fixed operational cost. Node provides the managed layer: deployment, monitoring, backups and support. Your documents stay on your infrastructure, your cost per signature is zero, and you own your signing stack outright.
