How does AI-native delivery affect pricing?

AI-native delivery is neither an automatic discount nor a guaranteed speed multiplier in advance. Accelerating repetitive, readily verifiable work allows more attention to business logic, integrations, validation and user value.

Proposals remain based on scope, risk, accountability and acceptance criteria; we publish productivity figures only when supported by documented, comparable project data.

Enterprise AI

Rapid AI Audit: 5 working days, from €3.8k + VAT
Full AI Readiness Audit: 2–4 weeks, custom quote
AI PoC: 4–6 weeks, from €9k net

A production AI solution is priced after reviewing integration, data, security and operating requirements.

All prices shown are net; VAT is payable separately. If an external service invoices in a foreign currency, we identify it separately in the proposal.

Yes, when scope and acceptance criteria are well defined. For longer programmes or those with high uncertainty, a phased, replannable framework reduces risk.

We can provide an initial order-of-magnitude range. A binding proposal requires at least the goal, critical processes, integrations, roles and acceptance criteria to be clarified.

A short description is enough for an initial range.
