Step01
You write, I answer
Not a form to a sales queue, the same inbox that gets everything else, read by the person who would do the work. Replies come within two working days, in English or Swedish. If it is not something I should take, you will be told that in the first reply rather than the third meeting.
Step02
Scope in writing, before anything starts
What is being built, what is explicitly not, what I need from you, and what it costs. Short enough to read in one sitting. If the shape of the problem is still unclear, that is what an audit is for, and an audit is a fixed fee, so the uncertainty is mine rather than yours.
Step03
Work in the open
You get access to what is being built as it is built: repository, staging, or the running system. No monthly status theatre, no progress you cannot verify yourself. If something is going badly you will hear it that week.
Step04
Handover that actually hands over
Documented, on your accounts, on your hardware, runnable by someone who is not me. The test is simple: could a competent engineer take this over without calling? If not, it is not finished. Retainers exist because people want them, not because the handover left a gap.
