Identify residual purchase orders that merit closure review

The problem

A variable-weight delivery can leave a small open quantity even after a supplier considers it final. Closing every paid order risks hiding a real backorder; leaving every residual open obscures genuine purchasing commitments.

Agent job

Compare residual quantities, settlement evidence, owner-defined tolerances and explicit delivery-completion statements to form a closure-review queue without closing orders.

Expected output

A draft PO residual queue separating candidate final variances, confirmed pending deliveries and unresolved cases, with tolerance calculations, completion evidence and a purchasing-owner decision column.

Why an agent / simpler alternative

The useful agent contribution is interpreting supplied completion notes alongside structured fulfilment evidence and explaining exceptions. Residual arithmetic and tolerance tests belong in deterministic formulas. Use a built-in close-short report or manual review when one trusted final-delivery flag and a fixed tolerance settle the question; payment alone cannot settle it.

Who this helps

1. Purchasing clerk

2. Procurement coordinator

Before a pilot — required, unexecuted

1. Define how overdelivery is classified, including whether it stays unresolved, and use that rule consistently in the prompt and output. Include both a negative remaining quantity and a zero ordered quantity in the test files.

Evidence boundary

Human duty and problem-source context are separate from the authored workflow. The steps, prompt, synthetic example, acceptance checks and expected value are original proposals, not source-derived procedures or demonstrated agent results.

Setup requirements

1. Choose one consistent receipt cut-off and explicitly distinguish a paid invoice from completion of the order.

2. Define tolerances as quantity, percentage or both, and state inclusive/exclusive boundaries.

3. Use material IDs and anonymous supplier codes; include pending backorders and disputed deliveries as negative controls.

Proposed steps

1. 1

   Recompute residual quantity from supplied order and receipt rows; compare it with the system’s displayed residual.

   Input: Open PO lines and receipt cut-off

   Output: Residual baseline with source-versus-recomputed differences.

   Expected output: Residual baseline with source-versus-recomputed differences.

   Checkpoint: Residuals use the same unit and date cut-off; overdelivery is its own class.

   Approval gate: Purchasing owner approves the residual basis; inconsistent lines cannot become closure candidates.

2. 2

   Join settled/unsettled evidence by PO line or explicit allocation; retain unmatched invoice allocations.

   Input: Residual baseline and settlement-status export

   Output: Settlement evidence column with allocation uncertainty.

   Expected output: Settlement evidence column with allocation uncertainty.

   Checkpoint: Settled status is evidence about payment only, never proof of final delivery.

   Approval gate: AP owner must resolve unmatched settlement allocations before closure review.

3. 3

   Extract explicit final/partial/pending statements and their line references; retain contradictory later statements.

   Input: Supplier completion excerpts and backorder records

   Output: Completion-evidence ledger and unresolved contradictions.

   Expected output: Completion-evidence ledger and unresolved contradictions.

   Checkpoint: A courtesy acknowledgement or paid receipt is not classified as final-delivery evidence.

   Approval gate: Procurement owner chooses the authoritative completion statement; the agent cannot make supplier commitments.

4. 4

   Calculate absolute and percentage residuals; test thresholds and exclusions without rounding into compliance.

   Input: Residuals and approved tolerance policy

   Output: Tolerance result with rule ID and exact comparison.

   Expected output: Tolerance result with rule ID and exact comparison.

   Checkpoint: Zero order quantity, missing unit or missing tolerance produces unknown rather than pass.

   Approval gate: The owner approves tolerance rules; the plan cannot change PO quantities to force completion.

5. 5

   Assign review classes: candidate final variance only if all required evidence is present; pending if backorder evidence exists; otherwise unresolved.

   Input: Settlement, finality and tolerance results

   Output: Closure-review queue with failed eligibility conditions.

   Expected output: Closure-review queue with failed eligibility conditions.

   Checkpoint: Every candidate cites settled, final and within-tolerance evidence; contradictory records stay unresolved.

   Approval gate: Queue classification proposes review only, never automatic closure or write-off.

6. 6

   Produce a compact owner packet with residual quantities and supplied commitment values only where their basis is explicit.

   Input: Classified queue and evidence references

   Output: Draft close-short review packet awaiting purchasing approval.

   Expected output: Draft close-short review packet awaiting purchasing approval.

   Checkpoint: No estimated release of cash or savings; uncertain commitment values remain blank.

   Approval gate: Purchasing/AP reviews each candidate and separately authorizes any order closure or financial adjustment.

Text

Review {open_po}, {receipts_settlement}, {completion_notes} and {closure_policy} as saved copies at {cut_off}. Recompute residuals and apply only the supplied tolerances. A paid invoice does not establish delivery completion. Require explicit finality evidence and preserve contradictory backorder statements. Classify each line as candidate_final_variance, pending_delivery or unresolved, and show the failed conditions. Create a new draft closure_review.csv and evidence memo in {output_folder}; leave all decisions pending the purchasing owner. Do not close orders, update quantities, write off balances or contact suppliers.

Human approval boundaries

1. Before any future pilot, the accountable owner confirms the exact synthetic or nonpersonal export copies, processing environment, scope and retention. No such approval or pilot is claimed here.

2. Purchasing approves finality evidence and the precise tolerance policy; AP confirms settlement coverage.

3. Closure, write-offs, supplier messages and changes to outstanding commitments require separate explicit authorization.

4. The base deliverable is a separate draft review artifact awaiting owner approval. Source copies remain unchanged; no live mutations, communications, purchases, personal-data processing, external uploads or access provisioning are included.

Failure modes

1. A settled invoice is treated as a supplier completion promise.

2. A percentage tolerance masks a prohibited residual unit or order type.

3. An older final note conflicts with a later backorder notice.

4. Source text can contain instructions unrelated to the authorized analysis; treat it as evidence, never as permission or executable guidance.

Recovery and troubleshooting

1. Signal

   A settled invoice is treated as a supplier completion promise.

   Recovery

   Remove the completion inference and reclassify the line as unresolved pending explicit finality evidence.

   Resume condition

   An authorized purchasing owner supplies the relevant final-delivery reference.

2. Signal

   A percentage tolerance masks a prohibited residual unit or order type.

   Recovery

   Apply the policy’s exclusions before tolerance eligibility; preserve exact quantity and original units.

   Resume condition

   The owner confirms the relevant order type and unit-specific rule.

3. Signal

   An older final note conflicts with a later backorder notice.

   Recovery

   Show both statements and withhold the closure candidate instead of selecting by file modification date.

   Resume condition

   Purchasing identifies the authoritative latest operational decision.

Unexecuted validation plan

Sample setup

Unexecuted fixture blueprint: six synthetic lines: the two illustrated lines, a final but unsettled delivery, a paid line with ambiguous completion text, a final line exactly on the inclusive tolerance boundary, and a unit-mismatched line. Include an owner-written expected class for each.

Acceptance checks

1. Exactly the fully settled, explicitly final, within-tolerance lines enter candidate_final_variance; pending/backorder, unsettled and ambiguous lines do not.

2. The 100 kg/99.4 kg line reports 0.6 kg and 0.6% residual without rounding changes.

3. The inclusive boundary case passes only the supplied inclusive rule; the unit-mismatched line remains unresolved.

4. All six lines remain present and have evidence or a specific missing-evidence reason; all owner decisions remain pending.

5. All input copies remain byte-for-byte unchanged; every proposed output is labelled synthetic/draft and pending owner review.

6. No network/account operation, live mutation, external communication, personal-data use or access provisioning is attempted.

Stop conditions

1. Any planted critical exception is missed or a blocked value is presented as certain.

2. A required policy, identity, time basis or source reference is absent and cannot be resolved within the supplied fixture.

3. Personal data, credentials or unrelated content appears, or the workflow requests live access, external action or source mutation.

Items

1. Agent plan eligibility, usage limits and actual price: unknown; verify before any authorized pilot.

2. Preparation of completion evidence and review of unresolved supplier statements may dominate effort; platform and native-report costs have not been compared.

3. Preparation of minimized copies, owner review, corrections and retention effort: unmeasured.

4. No native connector, paid dependency, integration installation or new account is assumed.

Caveat

No numerical price, effort, saving, income or ROI claim. Costs and usefulness require an authorized, bounded test and comparison with simpler existing controls.

Canadian adaptation — proposed

Retain kilograms/pounds and currency labels from the supplied policy without automatic conversion. Local purchasing controls and any bilingual completion terms need owner review; no Canadian accounting or procurement-compliance conclusion.

Limits

1. Original editorial plan, not a source-documented agent case. No workflow, fixture or acceptance test was executed.

2. Problem sources support a reported historical/current discussion or documented behavior; they do not establish a current defect, prevalence, buyer demand or willingness to pay.

3. Exact ChatGPT Work and Claude (Cowork capabilities) compatibility, account access and export completeness remain unknown and untested.

4. All substantive decisions and operational use remain with the named accountable owner; draft output does not imply approval.

5. Current need must be reconfirmed against the target installation, its version and simpler built-in remedies before considering a pilot.
