Warranty in German Law: Key Aspects for Businesses

Understanding warranty obligations is crucial for businesses, especially for startups in e-commerce and software sales. The following points summarize the most important aspects of warranty in Germany.

Warranty refers to the statutory liability for defects of the seller or contractor vis-à-vis the buyer or customer. This applies if the item or service is defective at the time of delivery.
Under sales law, consumers can initially demand supplementary performance (rectification or replacement) for a material defect or defect of title. If this fails, they are entitled to a price reduction or withdrawal from the contract, and potentially compensation.
The warranty period for new goods is 2 years (5 years for real estate). For used goods, this period can be reduced to 1 year for consumers. In business-to-business (B2B) transactions, warranty rights can be more extensively modified or excluded by contract.
A warranty must be distinguished from a guarantee promise. A guarantee is a voluntary commitment by the manufacturer or seller that supplements or extends the statutory rights.
For startups, particularly those involved in e-commerce or software sales, it is essential to understand their own warranty obligations. These should be clearly regulated in their general terms and conditions. Where permissible, providing for any warranty exclusions in B2B transactions is also important.

Statutory Regulations on Liability for Defects

The warranty in sales law is governed by §§ 434 ff. BGB (German Civil Code). A material defect exists if the actual condition of the purchased item deviates from its intended condition. For instance, the product might not function as described or be inherently flawed.

In the case of a contract for work and services (Section 633 BGB), a defect is present if the work does not possess the agreed quality or is unsuitable for its usual or contractually stipulated use.

If a defect is discovered, the buyer or customer generally has the following rights:

Subsequent performance: The debtor (seller/contractor) may first attempt to remedy the defect. In sales law, the buyer can choose between repair or delivery of a defect-free item. However, the seller can refuse one type if it involves disproportionately high costs.
Right of refusal: The seller can refuse subsequent performance entirely if it entails disproportionately high costs. This is rarely the case in practice.
If supplementary performance fails (e.g., after at least 2 unsuccessful attempts or unreasonable delay) or is refused, the buyer can declare a reduction in the purchase price or withdraw from the contract (against return of the item).
Compensation: Independently, compensation can be claimed under specific conditions if the seller is at fault. This includes, for example, negligent delivery of defective goods.
For contracts for work and services, analogous rights exist, such as the right to self-performance. This means remedying the defect yourself and demanding reimbursement of the expenses.

Warranty in B2C vs. B2B Business

Consumers benefit from comprehensive statutory warranty protection:

Reversal of the burden of proof: If a defect appears within 12 months (for contracts from 2022; previously 6 months) from handover, it is presumed that the defect existed at the time of handover. The seller must then prove the opposite if they wish to avoid subsequent performance.
Warranty cannot be contractually excluded or shortened for consumers when purchasing new goods. For used goods, a reduction to 1 year is permissible, but a complete exclusion is not allowed.
If the seller fraudulently concealed a defect or provided a guarantee for the quality, longer deadlines or special rules may apply.

In pure business-to-business (B2B) transactions, the warranty can be contractually modified:

Warranty periods are often shortened, for example, to 12 months. The warranty may even be completely excluded ("as inspected and purchased"), provided there is no fraudulent intent.
However, warranty cannot be excluded via § 444 BGB if the seller fraudulently conceals a defect or has assumed a guarantee for its quality.
In mutual commercial transactions, the obligation to inspect and give notice of defects (§ 377 HGB) is also crucial. Commercial buyers must inspect goods immediately upon receipt and report any defects. Failure to do so means the goods are deemed approved, and warranty rights are forfeited.

Differentiation from the Guarantee

A guarantee is a voluntary promise that extends beyond the statutory warranty. For example, a manufacturer might offer a 3-year guarantee on a product, while the statutory warranty is only 2 years. In the event of a guarantee claim, the entitled party can demand the services specified in the guarantee promise, often repair or replacement.

The guarantee does not replace statutory rights (§ 443 BGB) but exists independently alongside them.

It is important for customers to remember: always claim warranty from the contractual partner (dealer), while a guarantee is usually claimed directly from the manufacturer or guarantor.

Practical Advice for Startups

Startups that distribute products or software should consider the following points:

Be aware of your statutory warranty obligations. Customer service should have clear procedures for handling complaints, such as rectification by update/patch, exchange, or other solutions.
In their General Terms and Conditions (GTC), startups should appropriately limit warranty for B2B customers. This might include shortening the period to 1 year, excluding it for used parts, and implementing the obligation to give notice of defects.
Consider whether to offer a guarantee to build trust, for example, a "12 months functional guarantee." However, ensure that such a promise can be fulfilled, as it may incur additional costs.
When making their own supplier contracts, such as for components for hardware startups, review the terms carefully. Warranty exclusions by suppliers can affect the startup's own obligations, making this a potential point for negotiation.

Conclusion

Overall, statutory warranty provides essential basic protection for end customers. Startups should view this not as a burden but as a commitment to quality. Businesses that provide excellent products typically encounter fewer warranty cases, thereby strengthening customer loyalty through good faith and clear guidelines.
