04how buying works

No procurement theatre.

Step one

Free 3-file check, or a fixed-fee policy pack

Either find out whether you have a problem, or fix the AI documentation gap. Both are cheap, fast and useful even if you never engage us again.

Step two

A fixed number, in writing

Scope, deliverable, turnaround, fee and payment terms — one page, the same day you ask. Nothing starts until you approve it.

Payment

Card or invoice

Stripe checkout for speed; invoice with bank transfer for anything purchase-order shaped. 50/50 on most engagements.

Evidence

Everything is filable

Independence statements, DPIAs, registers, training records — written so that an insurer, a client or a regulator can accept them without translation.

Independence

Conflict check first

We do not review a firm we have advised, we never certify, and we take no vendor payments of any kind.
