What is enterprise-grade signing and how does it work?

Enterprise-grade signing means electronic signing operated as part of existing business processes rather than as a standalone app. Its defining characteristics are support for all eIDAS signature levels, integration into ERP, CRM, HR and document management systems via APIs, and configurable multi-party workflows.

Added to that are central user management with single sign-on, audit-proof logging and a choice of deployment models up to full on-premise operation. The value does not come from the signature itself but from removing media breaks — no printing, no scanning, no postal dispatch and no waiting between sending a contract and receiving it back.

Here's what defines an enterprise signing platform:

  • All eIDAS levels: Simple, advanced and qualified signatures on one platform, configurable per document template.
  • Deep system integration: API connectivity plus off-the-shelf integrations for common workflow systems across core banking, ERP, CRM and HRMS.
  • Configurable workflows: Serial and parallel signing, multi-party processes, delegation rules and dynamic form fields.
  • Scaling capabilities: Bulk signing, selective signatures and distribution of signature folders for high document volumes.
  • Long-term validatable formats: PAdES signatures with LTV and a qualified timestamp, shown automatically with a green tick in Adobe Acrobat.
  • Deployment flexibility: On-premise, managed service or cloud with EU hosting, complemented by SSO via OIDC or OAuth2.

Two common configurations:

  • Workflow-driven: Organisations needing complex, configurable signature workflows with form support and multi-party logic are served by primesign ENTERPRISE.
  • API-driven: Organisations that mainly trigger signatures via API from their own or third-party applications, without a workflow engine, run leaner with the primesign SIGNATURE SERVER.
  • Combination: Many organisations run both: the workflow engine for contracting, the signing hub for automated high-volume operations.

primesign offers both configurations from a single source: primesign ENTERPRISE as a fully configurable workflow solution and the primesign SIGNATURE SERVER as a signing hub for API integrations. Both support all eIDAS levels, instant signing with eIDs and future EUDI Wallets, and flexible deployment models with EU hosting.

  • Substantially shorter turnaround on contracts and approvals
