Receiving Shortage Invoice Offset
Find totals in your delivery checks and invoices that exceed the limits you supply.
A downloadable skill for your AI agent.
Your result
Billed quantities exceeding recorded receipt.
Source references, missing information, and questions to review stay with the findings.
How to use it
Add the skill to your AI
Open your download and follow the start guide. Use an AI agent that can load skill files and run the included tools.
Provide your records
Delivery checks and invoices. Confirm the case and period you want to check.
Ask for the report
Copy the request below into your agent. Add the files and any task details it needs.
Review and save
Check the findings against the original records. Choose where to save the report and follow up on open questions.
Example request
Use the Receiving Shortage Invoice Offset skill. Review the attached records: delivery checks and invoices. Prepare this result: billed quantities exceeding recorded receipt. Include a source reference for each finding. List missing information and questions that need my review. Ask me to confirm the scope and where to save the report before you start.
What it checks
It adds the amounts for the same item and unit, then checks the total against your limit. The report shows the amount above that limit.
What you provide
Delivery checks and invoices.
Details it records
- Recorded receipt
- Invoice quantity
- Documented tolerance
Read the full task logic
For this task, keep one review row for each delivery line + unit. Record recorded receipt, invoice quantity, and documented tolerance. Keep the source location beside each value.
Normalize purchase quantities using sourced pack size and units. Keep price, credit, free goods, substitution, waste, and inter-location transfer evidence distinct.
Compare like-for-like products and dates. A different pack can hide a unit-price increase. Use approved ingredient and food-handling records.
An amount below the bound is not proof of eligibility, correctness, or complete allocation. Negative values need a documented meaning.
Example result
This synthetic example shows the included check in use. Your agent uses its findings to complete your task report.
What you provide
Synthetic example records
| Starting record | amount: 100.00; unit: example units |
|---|---|
| Record to check | amount: 125.00; unit: example units |
What comes back
A difference needs review
- The total is above the limit supplied for this item.
- Expected
- 100.00
- Recorded
- 125.00
- Difference
- 25.00
This result comes from the checking tool in your download.
Read the source records
These are synthetic records from the bundled example.
- source-e1 · expected/e1
{"amount": "100.00", "id": "e1", "key": "delivery line + unit / SYNTHETIC-001", "unit": "synthetic-unit"} - source-o1 · observed/o1
{"amount": "125.00", "id": "o1", "key": "delivery line + unit / SYNTHETIC-001", "unit": "synthetic-unit"}
Checked values
- expected: 100.00; observed: 125.00; delta: 25.00; unit: synthetic-unit
Run this example
After purchase, extract the ZIP. Run these commands from the skill folder. Use a new output folder.
python3 scripts/checks.py
python3 scripts/audit.py assets/example.json \
--files-root assets/sample-files --output-dir example-resultExpected exit code: 1. Code 0 means no helper finding. Code 1 means a finding or review item. Code 2 means incomplete or invalid input.
The check uses the records you supply. Review each finding against the original documents.
What is saved
Ask your agent to save the completed task report in a folder you choose. The report template includes the result, source references, missing information, and next actions.
- A readable check report
- The local checking tool can save its findings as report.md.
- A data copy
- The same check can be saved as report.json for use in other tools. A local audit database is optional.

Collect the records
Start with delivery checks and invoices. Confirm the case, period, and source versions before the review.
Extract the task fields
Use supplier, product, pack specification, invoice line, location to keep records distinct. The agent records the original value, an exact quote, and the source location.
Check the supplied limit
Add records with the same key and unit, then compare their total with the supplied limit. Run the Python helper on the structured records. Check each finding against its source.
Complete the report
Prepare the task result: billed quantities exceeding recorded receipt. Include missing evidence, unresolved questions, and the next action for each open item.
