Terms of engagement

This page is not the contract

Every engagement runs on a signed scope that states the question, the deliverable, the fee and the dates. That document governs. This page describes how we work so you know what you are agreeing to before you read a word of legal drafting.

Nothing is billable until it is signed

Scoping conversations, a written view on whether there is work worth doing, and the answer “no, not yet” are all free. A conversation can end before a scope exists, and that is a normal outcome rather than a failed sale.

A Decision Audit is a fixed fee agreed in advance. It does not move because the work turned out to be harder than expected.

What you receive

The written findings, the code that produced every figure in them, and the limitations we could not resolve. Deliverables land in your repository, your cloud account and your credentials — not ours.

You own the outputs and the code we write for you. We keep our own general methods, tooling and know-how, which we will use again elsewhere; we do not reuse your data, your figures or anything specific to your business.

What we warrant

Every figure we hand you regenerates from the code we hand you. If a published number cannot be reproduced from the delivered repository, we correct it at our cost.

If a number we gave you later turns out to be wrong, you hear it from us before you hear it from anyone else.

We do not warrant business outcomes. Whether a better forecast becomes value depends on decisions taken inside your organisation, and we are not in a position to promise those. Any accuracy bar is agreed after we have seen the data, never before.

What we will not do

We do not resell software, take commission for recommending a platform, or hold a vendor partnership that would bias a recommendation. If the tool you already own is good enough, that is the answer you will get.

We will not build a model on a foundation that cannot be refreshed on a schedule, and we will say so before you spend money rather than after.

Confidentiality

We will sign your NDA before a scoping call, or provide a mutual one. Client names are not published without written permission — which is why this site shows public-dataset work instead of a logo wall.

Liability

Our liability under an engagement is limited to the fees paid for that engagement, and excludes indirect or consequential loss. Nothing here limits liability that cannot be limited in law. The precise wording lives in the engagement letter.
