General Business Terms and Conditions (T&C)

The following conditions apply exclusively to all of our quotes, deliveries, services and advice, and are an important constituent of the contract. Deviating or additional agreements, particularly customer purchasing conditions, only apply to us if they have been confirmed in writing. In the event of tacit acceptance of our T&Cs, the customer accepts our conditions and waivers his own conditions. Up-to-date details of our accreditation, particularly concerning the scope of our accredited procedures, can be found on our home page.

2. Quotes, order acceptance

Our quotes are subject to change. The contract is regarded as concluded when the order is confirmed or the work is completed by us. All special agreements, particularly verbal or telephone agreements, are only legally binding if we have confirmed them in writing or by e-mail.

3. Prices

All prices are net, excluding VAT. The work that is carried out in countries which are EU members is usually exempt of VAT, provided that the client has notified TZW: DVGW-Technologiezentrum Wasser (German Water Centre) of the EU identification number of his company. Work that is carried out in non-EU countries is usually exempt of VAT, provided that the client has notified TZW of the national tax number of his company.

We are entitled to make other work dependent upon prompt receipt of payment.

5. Liability

Liability of TZW within the scope of the order is ruled out unless legal regulations stipulate otherwise. Liability for indirect damages is ruled out in any case. Other compensation claims against TZW, particularly compensation for damages that did not occur on the object that is handed over itself, can only be asserted by the contract partner in the event of gross culpability of TZW or culpable infringement of important contractual obligations, provided that the achievement of the purpose of the contract is put at risk with regard to the foreseeable damages that are typical of the contract. Otherwise liability, particularly for consequential damages, is ruled out. Regardless of the legal basis, liability claims of any kind are limited to the invoice amount upon which the order is based.
