This is a fictional Australian business exercise. Today is 19 October 2026.
Use only the supplied CSV. Draft text here; do not use connected apps, create mailbox drafts, send anything, or change records.

First produce a review table: invoice, proposed action, supplied evidence, and missing checks.
Hold any invoice with a recent payment, a dispute, or without an explicitly verified current unpaid balance. Do not infer that missing payment data proves non-payment. If required facts are absent or inconsistent, hold it and say what the owner must check.

For eligible invoices only, write one polite first reminder per customer, in Australian English, with a subject and a body under 100 words. Preserve the supplied invoice number, AUD amount and original due date. Do not invent fees, payment links, bank details, deadlines, prior reminders or legal consequences. Do not recalculate tax.

Use Customer A/B/C as placeholders. Sign as [Business owner]. End with an owner checklist: verify recipient, current payment status, amount, due date and wording before any manual send.
