Invoice balance, payment amount, verified customer identity, owner policy and permitted refund/credit options.
How it works
- Verify invoice/payment/customer linkage and comparable currency.
- Calculate excess against the unpaid balance, preserving timing and prior credits.
- Describe only supplied permitted choices such as future credit or reviewed refund. Customer preference is not assumed.
- Return a decision note; no refund, ledger action, communication or bank-detail acceptance.
The output
customer/invoice | balance | payment | excess | policy options | identity gap | owner choice
Worked fictional example
Fictional unpaid 80 and matched payment 100 gives excess 20. Prior credit 10 already included in the balance is not deducted again. Refund versus credit remains an owner decision.
Checks and limits
Keep source versions and original values. Unknowns stay unknown. Use qualified review for regulated, legal or hiring decisions. No live account compatibility test, send, share, schedule, ledger change or payment is authorized.
