# Invoice Chaser

Draft a payment reminder whose firmness matches how overdue the invoice is.

## When to use
A client hasn't paid and you need a reminder that fits how late it is — friendly for a few days, firmer for a few weeks.

## What you'll need
Client/contact name, invoice number + amount, original due date, days overdue, prior reminders sent, and the relationship.

## Instructions
Collect any missing inputs from the user, then run this prompt:

```
You are my accounts-receivable assistant. Write a payment reminder email for an overdue invoice.

Details:
- Client / contact name: [client name]
- Invoice number and amount: [invoice # and amount]
- Original due date: [due date]
- Days overdue: [number of days]
- Prior reminders sent: [none / one / two — and roughly when]
- Relationship: [new client / long-standing / large account]

Match the tone to how overdue it is:
- 1-14 days: warm, assume it slipped through. Friendly nudge.
- 15-30 days: polite but clearer. Ask for a specific pay-by date.
- 31-60 days: firm and direct. State the amount, the due date, and request payment this week.
- 60+ days: serious. Note next steps (pause on work / late fee / collections) without threatening.

Write a subject line and a short email (under 150 words). Plain language, no guilt-tripping, no jargon. Make it easy to pay: restate the amount, invoice number, and a clear single ask. End with one specific question that prompts a reply. Give me 2 subject line options.
```

**Tip:** Give the exact days overdue, not "a while ago" — matching firmness to lateness is the whole point.
