The records decide. AI helps you check.

01 / VERIFIED FACTS + LIMITS

Check this explicitly fictional invoice table. Service amounts before tax: Invoice 001 amount 600 paid 600; invoice 002 amount 450 paid 200; invoice 003 amount 300 paid 0. Calculate total invoiced, cash received and each unpaid balance. Do not assume unpaid means overdue, because due dates are not provided. Do not change records or send any messages. Return a short plain-English summary and list what would still need verification against supporting records.

Gemini 3.1 Pro · Recorded September 10, 2026
**Summary of Accounts**

Based on the provided fictional records, the total amount invoiced for services before tax is $1,350, and the total cash received against these invoices is $800. 

The current unpaid balances for each invoice are:
*   **Invoice 001:** $0 unpaid balance
*   **Invoice 002:** $250 unpaid balance
*   **Invoice 003:** $300 unpaid balance

**Items Requiring Verification Against Supporting Records**

To fully reconcile these accounts, the following details would need to be verified against original documents (such as contracts, timesheets, bank statements, or receipts):

*   **Taxes:** The applicable tax rates and total amounts after tax for each invoice.
*   **Dates:** Invoice issue dates, payment receipt dates, and specific due dates (to determine current aging and if any unpaid balances are actually overdue).
*   **Client Information:** The names and billing details of the customers associated with each invoice.
*   **Payment Details:** The method of payment (e.g., check, wire transfer, credit card) and matching bank deposit records for the $800 received.
*   **Service Details:** The specific services rendered to justify the invoiced amounts.
