The Procurement AI Stack

Procurement AI should not just know what to do. It should know what it is allowed to read.

One-time. Updates included.
Organization Edition: one legal entity, internal sharing, no seat cap: $349
“Battle-tested in production environments.”
That is how Jared Spataro, Microsoft’s CMO for AI at Work, described my free, open-source Copilot prompt library in the AI at Work newsletter, February 2026. He was citing that free repo, not this product. This is the paid work from the same practice, held to the same standard.

The situation

Most AI guidance treats access as plumbing. In procurement it is the control itself. One agent that can read every live bid can carry one bidder’s price into another bidder’s clarification, and nobody in the room will see it happen. That is not a data-loss incident with a report to file. It is a tender you cannot defend.

The second problem is arithmetic that looks right. A savings register that ties out perfectly is the most convincing way to certify a double count, and a bid tabulation that ranks two bids on different bases hands the award to whoever excluded the most.

What this is

The Procurement AI Stack gives you one hundred mapped procurement activities, ten governed implementations, twelve gated workflows, fifty engineered prompts, and a test regime built around the mistakes that actually cost something.

Every agent ships with its read scope written down and its write paths set to NONE, the estate register records what each one may read before its first real use, and one scenario exists purely to try to make an agent reach outside its scope.

The fixtures are poisoned on purpose: a register that re-adds correctly and is still wrong by 23.3, one saving claimed twice across two initiatives, a baseline quietly restated against the same source document, a currency mismatch with no rate, bids where one excludes freight and duty and another annualizes a nine-month volume, and an index-linked increase the published index does not support. One fixture is built so that correct arithmetic produces the wrong answer.

What is inside

  • The 100-row procurement map: every major activity classified (49 agent-led with review, 15 AI-assisted, 8 automate, 24 never automate, 4 human only), 30 of them rows where the arithmetic has to reconcile to a stated baseline
  • Ten governed implementations, each with a build sheet, a spec, a written read scope, and a paste-ready instruction file with its character count
  • The 56-scenario test protocol, P-T1 to P-T56, as its own document: 10 clean inputs, 26 poisoned inputs, 10 three-turn pressure sequences, 9 controls where PASS means printing the zero, and 1 read-scope probe
  • Seven numeric fixtures carrying 90 pre-computed equations, 66 of them restated in ten answer keys that ship with the pack instead of sitting behind a support ticket
  • Fifty engineered prompts, twelve gated workflows including the read-scope and bid confidentiality reviews, a decision matrix, a nine-section governance pack, thirteen templates, a pre-filled estate register and a 30-day sprint
  • A 20-page Playbook PDF and a 15-tab workbook: the map with your own posture and owner columns, the paste shapes the agents expect, your procurement profile with its tail threshold and delegation levels, an agent test log with blank columns for your own run dates, and the value scorecard your CPO reads at day 30

Who it is for

  • Procurement and sourcing managers who need AI help without putting a tender at risk
  • Category managers and buyers whose savings numbers get audited later
  • The person who will be asked why they trust an agent that touched a supplier number

Who it is not for

  • Anyone wanting the award decision, the sanctions hit determination, purchase order release above the delegation threshold, or supplier bank detail changes to run without a person. Twenty-eight of the hundred activities are held back on purpose, and seven of those cost something.
  • Teams without a Microsoft 365 Copilot licence with Agent Builder. This is the instruction layer for a platform you already pay for.
  • Anyone wanting a pack whose testing was done for them. The 56 scenarios are yours to run, and the answer keys ship so you can grade them.

Questions people actually ask

Has this pack been tested?

Not on our side, and the pack says so rather than implying otherwise. What ships is the instrument: 56 scenarios, the fixture each one runs on, what a PASS has to produce, and ten answer keys so grading is arithmetic you re-add by hand rather than an impression. Run WF-1 on your own build before first real use, and you have a written result to put in front of the person who asks why you trust it.

Why is read scope treated as the headline control?

Because in procurement, access is the control. An agent that can read every live bid can move one bidder’s number into another bidder’s clarification without anything looking broken. So write paths are NONE, read scope is written down per agent, the estate register records it before first real use, and one scenario tries to break out of it.

What are the nine control scenarios for?

In nine of the 56, the finding is genuinely absent, and PASS means printing the zero instead of manufacturing something to look useful. Over-reporting destroys the credibility of the real findings, so the protocol grades for it.

Why should I not paste an answer key into the agent?

The key is the ruler. An agent that has seen the expected answer proves nothing, and a fix without a named fixture re-run does not count either. Grade against the key, never in front of it.

What is the difference between the two editions?

The files are identical; you are choosing usage rights. Individual ($99) licenses one named purchaser for their own work. Organization ($349) licenses one legal entity for internal use with no per-seat cap. Neither permits resale, public republication, or delivering the pack as paid training.

Buying this with a company card?

Most buyers expense it. Your receipt email carries a Generate link that opens an invoice generator: add your billing address, put your legal company name and any reference your finance team needs in the Additional notes box, and download the PDF. If you have an EU VAT number, enter it at checkout and no VAT is charged. Here is the approval email, so you do not have to write one.

Approval email
Subject: Approval request: The Procurement AI Stack ($99, one-time)

Hi [Manager],

I would like to expense a one-time $99 purchase: The Procurement AI Stack by Kesslernity.

What it is: Procurement AI should not just know what to do. It should know what it is allowed to read.

What we get:
- The 100-row procurement map: every major activity classified (49 agent-led with review, 15 AI-assisted, 8 automate, 24 never automate, 4 human only), 30 of them rows where the arithmetic has to reconcile to a stated baseline
- Ten governed implementations, each with a build sheet, a spec, a written read scope, and a paste-ready instruction file with its character count
- The 56-scenario test protocol, P-T1 to P-T56, as its own document: 10 clean inputs, 26 poisoned inputs, 10 three-turn pressure sequences, 9 controls where PASS means printing the zero, and 1 read-scope probe
- Seven numeric fixtures carrying 90 pre-computed equations, 66 of them restated in ten answer keys that ship with the pack instead of sitting behind a support ticket

Why it is worth it: it is a one-time purchase with future updates included,
and it costs less than an hour of any consultant we would otherwise ask.
The author publishes the open-source Copilot prompt library that Microsoft's
CMO for AI at Work cited as "battle-tested in production environments".

A downloadable invoice is available from the purchase receipt for expenses.
