# Credit Balance Application Order Check

## Inputs
Customer credit balance, open invoices, the application order policy and the ledger export.

## Workflow
1. Record the policy order, usually oldest invoice first.
2. Simulate the application against open invoices.
3. Compare the simulation to the posted application.
4. Return mismatches without posting adjustments.

## Output contract
Customer | credit | invoice order | applied | policy match | difference | reviewer

## Fictional acceptance test
Fictional account: credit balance 4,200; open invoices 2,000 due Nov 5 and 3,000 due Nov 20. Oldest-first policy gives 2,000 then 2,200 toward the second, leaving 800 open. A run that clears the Nov 20 invoice first breaks the order.

## Review gates
Re-check the policy order in writing before flagging. A different order changes which invoice ages.
