Qualified Electronic Signatures (QES) in HR: Providers, Criteria & Security
The qualified electronic signatures (QES) or qualified digital signature is gaining significance in the digital business world. It replaces handwritten signatures, is legally binding and eliminates the need for additional paper-based confirmation. It can optimize internal business processes in that it significantly expedites the finalization of strategically important contracts. The following article provides insight into essential aspects associated with the purchase and use of a qualified electronic signature.
Key Takeaways
- The qualified electronic signature (QES) replaces handwritten signatures, is legally binding under eIDAS and Section 126 of the German Civil Code (BGB), and offers the highest level of security for digital documents.
- It enables companies and HR departments to manage employment contracts, fixed-term agreements, and personnel records digitally, paperlessly, and in full compliance with the GDPR.
- Technically, the QES is based on asymmetric encryption, qualified signature creation devices (QSCDs), and certified qualified trust service providers (QTSPs), ensuring that documents remain tamper-proof.
- For businesses, this translates to efficient workflows, faster contracting processes, remote-work compatibility, and a modern digital transformation of HR and administrative operations.
What Does the Qualified Electronic Signature (QES) Mean for HR?
The qualified electronic signature (QES) is the most secure form of electronic signature and meets all requirements of the eIDAS Regulation (EU) No 910/2014. It fully replaces handwritten signatures and holds the exact same legal status under Section 126 of the German Civil Code (BGB). Electronic signatures have become an integral part of modern HR and business operations. They allow HR departments to sign and manage digital documents with full legal compliance—regardless of location or device.
Key Criteria

Case Study: 30-Minute Onboarding Thanks to QES
As it expanded to multiple locations, Euro-Union-Assistance reached its operational limits. Analog personnel files, scattered spreadsheets, and a lack of system integrations made data sharing sluggish. The recruitment process was a particular time-sink: every new hire required manual data entry and hand-crafting individual documents. To accelerate these and other operations, the company decided on implementing HR software. What used to take hours or even days is now completed by the HR team in just 30 minutes using HRlab. Within this short timeframe, all onboarding steps are fully finalized:
- Contract Execution: Legally binding signature (QES).
- Data Maintenance: Comprehensive profile setup without duplicate data entry.
- Document Verification: Centralized collection of all required hiring paperwork.
- Communication: Automated notifications sent to all relevant departments.
Qualified Electronic Signatures in HRlab
Within HRlab's document management system, digital signatures are a highly popular feature. To power this functionality, the partner solution YouSign is directly integrated. Once enabled, a signature icon appears on all PDF documents—whether in the digital personnel file, the recruiting module, or the main document menu. Clicking the icon opens a configuration dialog where you can set up options such as:
- Deadlines: Optionally define an expiration date by which signatures must be completed.
- Security (2FA): Enhance security by requiring two-factor authentication.
- Workflow Control: Set a fixed signing sequence or send the document to all signatories simultaneously.
Additionally, HRlab provides complete flexibility regarding signers. You can:
- Select internal employees directly from the existing database, or
- Manually add external parties (e.g., new candidates or service providers) using their name and email address.## Two Indispensable
What to Look for When Choosing HR Software with QES Functionality
If you are looking for an all-in-one HR solution that enables legally binding signing, you should include the following criteria in your software evaluation:
1. Certified Legal Compliance (eIDAS Compliance)
Inquire specifically about which Qualified Trust Service Provider (QTSP) is integrated into the background of the HR software. To guarantee exact legal equivalence to a handwritten signature, this provider must strictly be listed on the EU Trusted List. Without this proof, a QES is worthless for employment contracts.
2. Seamless Workflow Integration
Even the best signature feature is of little use if you have to manually export documents first. Check whether the signing process can be initiated directly from the digital personnel file or the recruiting module. Real value is only created when the contract status (e.g., "Pending Signature") updates automatically within the employee profile.
3. Cross-Border Recruiting
If you recruit talent from other EU countries, the solution must strictly comply with the eIDAS Regulation. Ensure that the software's identity verification tools are also designed to handle international identity documents.
4. Transparent Pricing Structure
When assessing the pricing model, check whether signature units (credits) are included in the software license or billed on a per-document or per-transaction basis. For mid-sized companies, flat-rate models or scalable packages are usually far more predictable than hidden individual fees for identity verification procedures.

Technical Background
At its core, a qualified electronic signature is a digital dataset uniquely linked to a specific person, guaranteeing both the authenticity and integrity of an electronic document. Technically, it relies on asymmetric cryptography within a Public Key Infrastructure (PKI):
The signatory holds a private signing key that remains under their sole control. This key generates a signature that can be verified using a public key, ensuring that the signed document cannot be tampered with after the fact.
A Qualified Trust Service Provider (QTSP)—supervised in Germany by the Federal Network Agency (Bundesnetzagentur)—issues the digital certificate confirming the signatory's identity. Only signatures generated through such certified trust service providers qualify as qualified electronic signatures under the eIDAS Regulation.
As a result, QES offers companies a legally binding, audit-proof, and GDPR-compliant way to sign digital documents, employment contracts, or agreements—forming a cornerstone of modern, paperless business operations.
Two Essential Characteristics of Every QES
A qualified electronic signature possesses all features of an advanced electronic signature (AES) while distinguished by two additional properties:
Qualified Signature Creation Device (QSCD)
The Qualified Signature Creation Device (QSCD)—known in German as Sichere Signaturerstellungseinheit (SSEE)—is the technical foundation of a QES. It consists of specially certified hardware or software that generates, stores, and uses the private signing key under the exclusive control of the signatory.
Typical forms of a QSCD include smart cards, USB tokens, or cloud-based solutions secured by a Hardware Security Module (HSM). This unit ensures that every signing key remains unique, confidential, and tamper-proof.
The legal basis is also derived from the eIDAS Regulation, supervised in Germany by the Federal Network Agency. Only through such a qualified signature creation device can the highest level of trust for an electronic signature be achieved.
Strict Identification and Issuance Procedure
Before a qualified electronic signature can be used, the identity of the signatory must be verified beyond doubt. This process is carried out by a Qualified Trust Service Provider (QTSP), which issues the digital certificate.
Identity verification can take place in person or via secure online identification methods such as VideoIdent, AutoIdent, or eID using an electronic ID card. These procedures ensure that only the authorized individual receives and uses the signing key.
FAQ
How Do You Obtain a Qualified Electronic Signature?
You can obtain a qualified electronic signature (QES) from a certified Qualified Trust Service Provider (QTSP). The process involves identity verification (in person, via VideoIdent, or using an eID), after which a digital certificate is issued alongside any required hardware, such as a smart card or token, to enable secure signature creation.
When combined with HR software, a QES integrates directly into digital workflows. Employment contracts, fixed-term clauses, or personnel file updates can be signed paperlessly, in an audit-proof manner, and in full compliance with the GDPR. Many HR systems provide native integrations that automatically connect signatures to documents, making onboarding processes, contract management, and HR administration significantly more efficient.
When Is a Simple Electronic Signature Sufficient?
A simple electronic signature (SES) is sufficient for internal documents or less legally critical processes, such as internal agreements, time-tracking records, or HR forms without statutory written-form requirements. However, for documents with legally mandated written-form requirements or high legal significance—such as employment contracts or supplementary agreements—a qualified electronic signature (QES) is required.
What Is a Simple Electronic Signature Under the eIDAS Regulation?
Under the eIDAS Regulation, a simple electronic signature (SES) refers to any electronic data attached to or logically associated with other data in electronic form which is used by the signatory to sign. It does not need to meet any special security requirements. It can take the form of a scanned signature, a click on an "I Agree" button, an email confirmation, or a basic digital certificate, and is suitable for documents with no statutory written-form requirements.
