Response times, requirements & exceptions

Concept and fixed-price proposal within 12 business hours (Monday–Friday, 08:00–20:00 Europe/Berlin; only time within this window counts) after a complete project inquiry arrives through our form. Inquiries outside these hours count from 08:00 on the next working day; public holidays move the deadline accordingly. This applies to projects up to €25,000 excluding VAT. Larger projects receive an initial assessment within 12 business hours and a concept within 3 working days. Existing code, online multiplayer, medium or large games, and health or payment data receive an initial assessment and an offer for a code audit or concept phase within 12 business hours. That offer states whether later work can be fixed-price or will be charged by time spent. The inquiry is non-binding.
