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
- 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.
Goes to the named buyer to approve.
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
Human approval stays in control
Outside the boundary — human approval required
8 items
- Releasing a purchase order to a supplier.
- Approving an alternate part for a build.
- Concluding that a part is authentic.
- Releasing anything a screening hit stopped.
Automation boundary
Agent acts unaided
- ✓Shortlist candidate parts and suppliers from your configured sources.
- ✓Name the distribution path behind each candidate.
- ✓Assemble the evidence pack a buyer reads before deciding.
- ✓Stop on a screening hit, and hold the line for the named owner.
Any write happens inside the boundaries agreed at implementation, never ahead of the buyer.
- Accepting a path outside authorised distribution.
- Certifying substance or minerals compliance.
- Determining country of origin or duty treatment.
- Changes to approved sources or screening rules.
Example output
One candidate part, annotated
Everything the agent puts forward is attached to the record it was drawn from.

Why this candidate
Inside authorised distribution — a control on the path, not on the part.
What the score decides
Below the configured threshold the shortlist takes an engineering read first.

Where AI adds value
The same four claims, placed at the point in the workflow where each one applies.
Where the value lands
Value 01 – 04
Each demand line
From your own sources
Shortlist from your data
Draw on the approved-supplier list, the distribution records and the source rules your desk configured.
Shortlist, and name the source
Repeat buys arrive with the path already named and the evidence already attached.
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.
Build 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.
ERP and MRP
- SAP S/4HANA Sourcing
- Oracle
- Infor
- Epicor
PLM and part data
- Teamcenter
- Windchill
- SiliconExpert
- Z2Data
Authorised distribution
- Franchised distributor feeds
- Manufacturer lifecycle notices
Agent
Procurement and sourcing
- Reads your sources
- Shortlists candidates
- Holds for approval
Screening lists
- UFLPA and denied-party lists
- GIDEP and ERAI alerts
Observability & evaluation
- OpenTelemetry
- Langfuse
- Supported monitoring/evaluation sources
Integration availability depends on the client's existing systems and API access.
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.
L6 · Outermost — last line of defence
Inward → L1 · closest to the model
- L1 – L2
- Test whether a candidate may stand
- L3
- Puts the order in a buyer's hands
- L4 – L5
- Keep the candidate and the path it came through
- L6
- Falls back to authorised-source lookup when signals degrade
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.
Surface — the shortlist the buyer reads
- E1Final-output evaluationDid each candidate carry the distribution path its record supports?
- E2Step-level evaluationDid the agent use the right approved sources and screening configuration?
- E3Tool evaluationDid it read and write the correct requisition and the correct line?
- E4Confidence calibrationDo low-confidence shortlists actually attract more buyer amendments?
- E5Slice evaluationHow does performance change across specific commodity groups?
- E6Business outcomeHow many lines needed an amendment, or a correction after the order went out?

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.
Slice performance — reported separately, not only in aggregate
Illustrative example| Slice | Failure rate | Lift | Lift vs. threshold | Status |
|---|---|---|---|---|
| Alternate parts for obsolete lines | 7.3% | 3.4× | Review | |
| Suppliers new to the approved list | 4.5% | 2.1× | Review | |
| Allocated and long-lead commodities | 3.4% | 1.6× | Watch | |
| Repeat buys on an authorised path | 1.9% | 0.9× | Normal |
Bar: amendment-rate lift vs. the repeat-buy baseline · scale 0–4.0× · tick marks the 2.0× review threshold
2 of 4 slices over threshold
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 stages
Switchback — the path turns at Improve and returns at Learn
- 01
Detect
Amendment rate rises in one commodity slice.
- 02
Diagnose
Read back through the shortlists and the records behind each candidate until a single cause is left standing.
- 03
Improve
The fix is versioned with the shortlists that motivated it.
- 04
Verify
Nothing ships while an affected case is failing.
- 05
Learn
The case is added for good, and the sourcing rules change.
Learn → Detect
The 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.
