Digital Signing & E-Invoicing

Why Self-Host Your Digital Signing and E-Invoicing?

DocuSign charges $10-40/user/month and Adobe Sign starts at $15/month — for what is essentially adding a cryptographic signature to a PDF. These services also store your signed documents (contracts, NDAs, employment agreements) on their servers, creating exposure for your most legally sensitive files. Self-hosted digital signing tools handle the same workflow on your own infrastructure.

Self-hosted e-signature platforms provide document upload, signature field placement, email-based signing workflows, and audit trails with legally valid electronic signatures. The signed documents and their audit logs stay on your server, never passing through a third-party service. This is particularly important for legal firms, healthcare organizations, and financial institutions where document confidentiality is regulated.

E-invoicing is the related use case — generating, sending, and tracking invoices in standardized electronic formats required by an increasing number of countries. Self-hosted e-invoicing tools ensure your invoice data (client details, amounts, tax information) stays within your infrastructure while meeting format requirements like Factur-X, ZUGFeRD, or Peppol. As e-invoicing mandates expand across the EU and other regions, having this capability on your own servers avoids vendor lock-in during a rapidly evolving regulatory landscape.
