Customer credit balance, open invoices, the application order policy and the ledger export.
Workflow
- Record the policy order, usually oldest invoice first.
- Simulate the application against open invoices.
- Compare the simulation to the posted application.
- 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 and limits
Re-check the policy order in writing before flagging. A different order changes which invoice ages.
