AdES vs QES: Which Electronic Signature Level Does Your Logistics Business Actually Need?

If you are preparing your logistics business for the eFTI mandate or rolling out eCMR, you have probably hit the same question every transport manager eventually asks: what type of electronic signature do we actually need?

The answer matters more than you might think. Choose too low and your documents may not hold up in a dispute. Choose too high and you are paying for infrastructure you do not need while slowing down operations at the loading dock.

This guide breaks down the three levels of electronic signature under the eIDAS regulation — SES, AdES, and QES — with a specific focus on what logistics companies need for eCMR, freight contracts, and cross-border transport documentation.

The Three Levels of Electronic Signature Under eIDAS

The eIDAS regulation defines three levels of electronic signature, each with increasing security and legal weight. Understanding the differences is essential before investing in any digital signing solution.

Simple Electronic Signature (SES) is the broadest category. It covers anything from a scanned signature to ticking an "I accept" checkbox. Under eIDAS, an SES cannot be denied legal admissibility simply because it is electronic, but it carries the weakest legal standing. In a dispute, the burden of proof falls entirely on the party relying on the signature. For logistics, an SES might work for low-risk internal confirmations, but it is not suitable for consignment notes or contracts.

Advanced Electronic Signature (AdES) is where things get serious for freight. An AdES must meet four specific criteria under eIDAS Article 26: it must be uniquely linked to the signatory, capable of identifying them, created using signature data under the signatory's sole control, and linked to the signed data so that any subsequent change is detectable. This means the signer's identity is cryptographically verified and the document's integrity is guaranteed. An AdES is legally binding across the EU and provides strong evidential value in court.

Qualified Electronic Signature (QES) adds two further requirements on top of AdES: the signature must be created using a Qualified Signature Creation Device (QSCD), and it must be based on a qualified certificate issued by a Qualified Trust Service Provider (QTSP) listed on the EU Trusted List. A QES is the only electronic signature type that is automatically considered equivalent to a handwritten signature under EU law. It carries the highest probative value and is essentially non-repudiable.

Why AdES Is Sufficient for eCMR and Most Freight Documents

Here is the key insight that can save your logistics company significant time and cost: for eCMR and the vast majority of freight transport documentation, an advanced electronic signature is legally sufficient. You do not need a qualified electronic signature.

The eCMR protocol requires a credible electronic signature that ensures authenticity and integrity. An AdES meets both requirements. The eFTI regulation similarly requires electronic freight transport information to be authenticated and integrity-protected, which an advanced electronic signature provides.

This is confirmed by industry practice across Europe. The Open Logistics Foundation's eCMR standard uses advanced electronic seals. Spain's implementation of eCMR requires advanced electronic signatures. Platforms already operating eCMR services across Benelux, Germany, and Scandinavia rely on AdES-level signing.

The practical difference is significant. An AdES can be generated remotely, using a mobile device and biometric verification, in seconds. A QES typically requires a qualified certificate issued through a QTSP, often involving hardware tokens or face-to-face identity verification, adding cost and friction to every signature event.

For a logistics operation processing thousands of consignment notes daily, that friction adds up fast. When a driver is standing at a loading dock with a queue of trucks behind them, the difference between a 30-second mobile signature and a multi-step qualified signing process directly impacts operational throughput.

When You Actually Need QES in Logistics

That said, QES is not irrelevant to logistics businesses. There are specific use cases where only a qualified electronic signature will do.

Public sector tenders and procurement in several EU member states require QES for bid submissions. If your logistics company bids on government freight contracts, you may need QES for those specific documents. Notarial transactions and real estate related to logistics infrastructure (warehouse purchases, long-term lease agreements) typically require QES. Certain regulatory submissions to national transport authorities may specify QES, depending on the member state.

The pattern is clear: QES is typically required when national law explicitly mandates a handwritten signature equivalent, or when you are dealing directly with public authorities. For commercial freight documentation — consignment notes, delivery confirmations, carrier agreements, warehouse receipts — AdES is the appropriate level.

A practical approach for most logistics companies is to standardise on AdES for daily freight operations while maintaining QES capability for the occasional high-value contract or regulatory submission that requires it.

The Cross-Border Complication

The choice between AdES and QES becomes more complicated when you add cross-border logistics into the mix. Within the EU, both AdES and QES are recognised across all 27 member states under eIDAS. But what happens when one party in the signing chain is from outside the EU?

This is exactly the scenario that plays out millions of times daily in European logistics. A carrier based in Turkey, a driver from Ukraine, a supplier from Morocco — none of them have access to a European eID or a QTSP-issued qualified certificate. The upcoming EUDI wallet will cover EU citizens, but not the 152 other countries that trade with Europe.

For cross-border freight involving non-EU parties, AdES is often the only practical option. QES requires a qualified certificate from an EU-recognised QTSP, which is typically unavailable to signers outside the EU. An AdES, by contrast, can be generated using identity verification based on biometric passports — which are available in 179 countries.

At IdentiGate, this is precisely the problem we solve. Our platform creates a device-bound digital identity from any biometric passport via NFC, and generates advanced electronic signatures that meet eIDAS requirements. A Turkish driver signs an eCMR with the same legal standing as a German warehouse operator — no paper, no special hardware, no dependency on national eID infrastructure.

Choosing the Right Signature Level: A Decision Framework for Logistics

Rather than defaulting to the highest (and most expensive) signature level for everything, consider matching the signature type to the document type and risk level.

Use AdES for eCMR and electronic consignment notes, delivery confirmations and proof of delivery, carrier agreements and rate confirmations, warehouse receipts and goods handover documents, cross-border freight documents involving non-EU parties, and any high-volume document workflow where speed matters.

Use QES for public sector procurement bids that explicitly require it, notarial or real estate transactions, regulatory submissions where national law mandates a handwritten signature equivalent, and high-value contracts where maximum legal assurance justifies the additional cost and friction.

Avoid SES for any transport document that could be subject to a dispute, insurance claim, or regulatory inspection. The cost difference between SES and AdES is minimal, but the legal difference is substantial. A driver's finger scrawl on a tablet screen may feel digital, but without proper identity verification and integrity protection, it is easily repudiated in court.

What This Means for Your eFTI Preparation

With the eFTI regulation making digital freight information mandatory from July 2027, every logistics company in the EU needs to make a decision about electronic signatures. The good news is that for the vast majority of freight documents, AdES provides exactly the legal standing you need — without the cost, complexity, or operational friction of QES.

The companies that get this right will have a significant advantage. They will digitise their document workflows faster because AdES is simpler to deploy. They will handle cross-border freight seamlessly because AdES works with identity documents from 179 countries, not just 27. And they will avoid overpaying for QES on documents that do not require it.

The companies that get it wrong will either under-invest (using simple electronic signatures that do not meet eCMR requirements) or over-invest (requiring QES for every consignment note, creating bottlenecks and excluding non-EU partners from digital workflows).

Start by mapping your document types to the appropriate signature level. For most logistics operations, the answer will be clear: AdES for 95% of your freight documents, QES reserved for the 5% where the law explicitly requires it.
