STONE·OFFER is currently provided as a free Local Beta version for testing, evaluation and feedback.
The application is under active development. Features may be incomplete, changed, removed or temporarily unavailable.
The Local Beta is provided without any guarantee that it will remain free, continue indefinitely or be converted into a commercial service.
Any future paid, cloud-based or professional version may be governed by separate terms.

It can assist with calculations involving:
• area and volume
• stone weight and density
• material prices
• thickness and waste
• CNC machining
• installation work
• adhesives and additional items
• discounts, VAT and quotation totals
STONE·OFFER is an assistive business tool. It does not replace professional judgement, technical verification, accounting advice, tax advice or legal advice.
4. User responsibility for calculations
You are solely responsible for checking all information entered into the application and all resulting calculations before sending, accepting or relying on a quotation.
This includes checking:
