Generate Invoice

If the user hasn't provided enough information (e.g. missing client email or bank details), ask before generating. Do not proceed without bank details.

How to Generate

Write a temporary Python script to /tmp/generate-invoice.py using fpdf2 and run it. Before running, ensure fpdf2 is installed:

pip install --quiet fpdf2 2>/dev/null || pip install --quiet --break-system-packages fpdf2

The script must produce a PDF with this exact layout:

1. Title: "INVOICE" in Helvetica Bold 24pt.
2. From / To: Side by side. Bold labels, then name and email on separate lines.
3. Dates: "Date:" and "Due Date:" as bold labels with values beside them.
4. Line items table: Columns; Description (left-aligned), Qty (right), Rate (right, £), Amount (right, £). Header row with light grey background (#F0F0F0). Helvetica 10pt.
5. Divider line below the last row.
6. Total: Bold 12pt, right-aligned, with £ symbol.
7. Bank details: Below the total. Bold label "Bank Details", then account name, sort code, and account number on separate lines. Helvetica 10pt.

Use fpdf2 with FPDF. Use Helvetica font only. Currency is GBP (£). Page size A4.

Output

Save the PDF to ~/Downloads/ with this filename format:

YYYY-MM-DD_Sender-Name_Client-Name.pdf

Rules for the filename:

• Date is the invoice date
• Names are title-cased with spaces replaced by hyphens
• Remove any characters that aren't alphanumeric or hyphens
• Example: 2026-03-20_Katie-Smith_Acme-Corp.pdf

Print the full output path when done and confirm to the user.
