Licence and payment terms
- Binding order. By clicking “Place binding order” you place a binding order for a PDR Kalk licence. Sales are to business customers only (B2B).
- Price. Switzerland: CHF 550 plus 8.1 % VAT. EU companies with a valid VAT ID: EUR 580 without VAT (reverse charge).
- Payment. You receive the invoice by email. It is payable by bank transfer within 14 days of the invoice date.
- Delivery. The licence is issued once payment has been received in full and is sent to you by email.
- Scope of the licence. A permanent, perpetual licence with no subscription, for commercial use by one business. It may be installed and used on any number of the licensee's devices.
- Tied to the business. The licence is permanently tied to the company and address given in the order. The company name and address cannot be changed after issue, and the licence cannot be transferred to another company.
- No returns. PDR Kalk can be tested free of charge and without obligation for 30 days before purchase. There is therefore no right of withdrawal, return or refund. Statutory warranty rights for defects remain unaffected.
- Updates. Regular updates are included free of charge. Larger add-on modules may be offered optionally for a small fee; buying them is voluntary.
- AI features. Built-in AI features are optional and may rely on evolving AI services. They require your own API key from the chosen provider; setup and costs are the customer's responsibility. Availability, accuracy and behaviour are not guaranteed.
- Help, tariffs and liability. No IT support is owed; you learn the app through the trial, the demo data and the built-in manual, and email help is voluntary. Tariffs and calculations are tools — the customer checks every outgoing document. Liability is excluded to the extent permitted by law. Details in the terms and conditions.
- Governing law and jurisdiction. Swiss law applies. The place of jurisdiction is Schaffhausen, Switzerland.
