Procurement & Sourcing AI Agent

Shortlist parts and suppliers from your own sources, name the distribution path behind each candidate, and hold every alternate part for the named buyer who decides whether it is ordered.

What this agent does

Shortlists the part, not the decision to buy

In
01

Ingest the demand line, the bill of materials and the approved-supplier list from supported ERP, PLM or MRP sources.

02

Normalise each line to a full manufacturer part number, and hold anything that resolves to more than one part.

Reason
03

Shortlist candidates from the sources your desk configured, and from no other customer's buying data.

04

Name the distribution path behind each candidate — manufacturer, authorised supplier, or outside that hierarchy.

05

Mark the point where a path leaves authorised distribution, and state what the buyer would be taking on.

Decide
06

Screen each supplier and each part against the forced-labour and restricted-source lists on file.

07

Stop the line on a hit and route it to the named owner, who is the one who reports it.

Out
08

Retain the sources read, the path stated, the screening result and the buyer's decision on the requisition.

09

Execute write actions only inside the approval boundaries agreed during implementation.

Product statement

The agent shortlists and names the path; a named buyer decides whether an alternate part is ordered — and once a buy leaves authorised distribution, authenticity is the buyer's to answer for.

Example workflow

One demand line, shortlist to order

AgentHuman
1Demand receivedERP requisition, MRP shortage, BOM change or a buyer's request
2Sources assembledApproved-supplier list, authorised-distribution records, lifecycle notices and stock, each with its as-of date
3Shortlist draftedCandidate parts, the distribution path behind each, screening result and confidence
4Controls appliedApproved-source checks, distribution-path checks, the configured screening lists and confidence threshold
No human action required

Stages 1 to 4 run unaided, and nothing is ordered at any of them — the agent is shortlisting, and the buyer's lane opens at the confidence gate.

5DecisionBranches at the confidence threshold
High confidence

Goes to the named buyer to approve.

Low confidence

Adds a component-engineering read first.

Buyer approval

The shortlist is held with its sources, the path behind each candidate and the confidence.

Approve · Amend · Send to engineering review
Approved — released to order
6ERP and PLM updatedOnly where write access and approval policy allow it
7Outcome evaluatedAmendment distance, path outcomes, screening stops and nonconformances found after the order
Amendments

Each buyer amendment is counted in the evaluation.

What should not run autonomously

Value

Where AI adds value

The same four claims, placed at the point in the workflow where each one applies.

Where the value landsValue 01 – 04
Each demand lineFrom your own sources
03Shortlisting

Shortlist from your data

Draw on the approved-supplier list, the distribution records and the source rules your desk configured.

01Approved path

Shortlist, and name the source

Repeat buys arrive with the path already named and the evidence already attached.

02Human review

Put the read where the risk sits

Screening stops, unauthorised paths and low-confidence candidates are marked, so the buyer's read starts where the risk concentrates.

04Build an evidence trail

The candidate part, the distribution path behind it and the buyer who approved it stay on the order file.

Integrations

Typical integrations

Five system groups connect to the same agent. Which of them are in scope is decided in discovery.

Agent controls

Six layers between the model and the order

Every control encloses the next. What survives the set is named in the map below.

How Nestack evaluates it

Evaluate the sourcing workflow — not only the part at the end of it.

Coverage runs the whole depth of the workflow, and every layer is cut by slice.

Affected slices

Overall shortlist quality can hide one cohort

Break the amendment rate down by commodity before you trust it. The lines carrying it are the ones a buyer would have asked to see first — obsolete parts, and suppliers new to the approved list.

Evidence-linked improvement

The loop shuts when the case is written

The loop closes on a case the next release must pass, not on an explanation. That suite is what the next part put forward to a buyer is measured against.

Improvement cycle · five stagesSwitchback — the path turns at Improve and returns at Learn
01Detect

Amendment rate rises in one commodity slice.

02Diagnose

Read back through the shortlists and the records behind each candidate until a single cause is left standing.

03Improve

The fix is versioned with the shortlists that motivated it.

04Verify

Nothing ships while an affected case is failing.

05Learn

The case is added for good, and the sourcing rules change.

Learn → DetectThe return edge. Detection is re-run against a suite that grew.

Typical build scope

Next step · Electronics AI agent

Build a sourcing agent around the buyer who already signs the order.

Show us your approved sources, your screening lists and who accepts an alternate part. You bring the source hierarchy you already buy to and the named buyer who signs. We map the sourcing workflow, set the automation boundary and leave the order where it sits.
