Online sales are subject to strict legal checkout requirements that many retailers do not adequately consider.

Legal checkout obligations within the EU

At KoneX, we look beyond simply connecting systems. Together with our legal partner Vestius Attorneys at Law, we regularly share insights that go further than integrations and automation.
E-commerce is not only about connecting systems and configuring the entire online sales process end to end, but also about making sure that each step meets all legal requirements.

Your checkout, the information you display, the wording on your buy button, can directly influence your legal position and your revenue. KoneX supports this by making the entire chain consistent, traceable and technically watertight, helping retailers comply with these obligations without operational chaos.

Does this apply outside the EU? Yes, as soon as you sell to EU consumers

These rules apply to online retailers selling from within an EU country, as well as those located outside the EU who deliver to consumers within the EU.

The moment your webshop targets consumers inside the EU, you must comply with the information requirements, the right of withdrawal, and the rules governing the buy button, regardless of where your business is registered or where fulfilment takes place.

These rules therefore apply to

Online Retailers within the EU selling cross-border
Online Retailers outside the EU (e.g., UK, US, Turkey, Switzerland, India, China, etc.) selling to EU consumers
Marketplaces and webshops serving the EU market

In short: anyone selling online to consumers in the EU is subject to these legal obligations.

Why these rules matter now more than ever

Courts increasingly check compliance on their own initiative, even if the consumer hasn’t raised any objections.

even if the consumer hasn’t raised any objections, judges look at:

Was all mandatory information shown before the purchase?
Was the buy button wording unambiguous?
Can the retailer prove this?

If proof is missing, or the information was unclear, your position as an online seller becomes vulnerable.

Your checkout must not only be compliant; you must be able to prove it was compliant at the moment of purchase.

What information you must show before the customer purchases

EU consumer laws require online retailers to clearly display the following before the customer completes a purchase:

Main characteristics of the product or service
Identity and physical address of your business
Total price, including VAT and all unavoidable costs
Any extra communication charges
Payment method, delivery method, fulfilment and delivery timeframe
Right of withdrawal (14 days) + clear instructions
Contract duration or termination conditions for ongoing services
Minimum contract duration, where applicable

This information cannot be hidden in your terms and conditions: it must be part of your checkout flow.

Record-keeping: no proof means no compliance

Online Retailers must be able to demonstrate what the customer saw.

That means retaining:

Screenshots of your checkout flow
Version history of checkout and pricing pages
Templates of confirmation emails
System logs (used carefully and GDPR-compliant)

After the purchase, you must provide the same information in a durable and accessible format, typically via email.

Where KoneX helps:
Retailers often work with a mix of webshop software, marketplaces, ERP systems, WMS platforms, and carriers. This creates mismatches and outdated data. KoneX ensures uniform, consistent and traceable order information across all systems, making it far easier to demonstrate compliance.

The button: clarity is not optional

The buy button must explicitly indicate a payment obligation.

Legally safe:

“Order and pay”
“Checkout”
“Buy now (payment obligation)”

Risky:

“Order now”
“Continue”
“Confirm”
“Next”

If the buy button is unclear, the contract or part of it may be unenforceable.

Example:
European courts, including the German Federal Court of Justice have ruled that if a buy button does not clearly indicate a payment obligation (e.g., using wording like “Continue” or “Next”), the contract may be considered invalid, making claims unenforceable.

After the purchase: information again, in durable form

The confirmation email must include:

Order summary
Total price
Delivery timeframe
Withdrawal information
Termination conditions (if applicable)
Terms and Conditions (link or attachment)

A popup or banner is not sufficient.

What if you don’t comply? (20 to 60% reduction of your claim)

Courts can reduce your claim drastically when:

Buy button wording is ambiguous
Mandatory information was missing
Evidence cannot be produced
Contract duration is unclear

Checkout mistakes don’t just reduce conversion, they can cost you real money in court.

Additional obligations you must consider

In addition to these essential information requirements, other regulations apply:

GDPR
Cookie legislation
Omnibus Directive (discount price rules, transparency)
Marketplace and webshop obligations
Cross-border sales requirements within the EU

Compliance in e-commerce is not a one-time task: it’s part of building an operationally mature organisation.
