Time-to-first-PR
Hours go to scoping calls, billing meetings, change orders.
Every hour spent debating scope is an hour billed. Every change request restarts an estimate cycle. Your first real production PR is often two weeks of meetings deep — and you've already paid for it.
Sprint Zero is included. PR by day two.
Architecture and scope are settled in the €2,000 Blueprint, before any sprint clock starts. Day one of Sprint One is implementation. First PR by day two — unbilled meetings included in the fixed fee, not piled on top of it.
