Digital signatures should simply work – without hidden costs, contract terms or unnecessary complexity.
SK-OneSign is a professional signature platform that consistently follows this approach.
You only pay when you actually sign: no subscriptions, no monthly fixed costs, no obligations.
This deliberately sets SK-OneSign apart from providers that tie their services to rigid subscription models, usage limits or additional packages.
You sign exactly as much as you need – flexibly, transparently and fully demand-based.

Simple. Secure. Traceable.

Use SK-OneSign exactly when you need to sign documents – without subscription and without recurring costs.
Upload a document, define signers, complete the process – structured, professional and transparent.

Signatures without compromises

Despite its simple usage model, SK-OneSign provides the complete technical infrastructure for professional digital signature processes.

Precise signature fields, documented hash values and a complete audit trail make every signature process technically traceable and verifiable.

Technical basis:
• Calculation of a SHA-256 hash value to identify the final document version
• Complete audit trail with timestamps, IP addresses and participating signers
• Clear assignment of all signatures and fields to the respective document

All data and documents are automatically and completely deleted after a defined period – traceable, rule-based and without manual intervention.

Only data required for the signature process is processed. After completion, all sensitive content is properly removed.

Whether one person or several persons (max. 20) – SK-OneSign adapts flexibly to the respective use case without a subscription or license model.

Every action in the signature process is clearly documented and included in the final PDF output in a traceable form.

Ideal for companies, freelancers and organizations that need a reliable digital signature solution without committing to a long-term subscription.
