Purchase Order

Generate a professional purchase order document with the following details:

Vendor Name: {{vendor_name}}
Items/Services: {{items}}
Total Amount: {{total_amount}}
{{po_number_line}}
{{delivery_line}}
{{payment_line}}

Create a complete, professional purchase order that includes:
1. A clear header with PO number (generate one if not provided) and date
2. Vendor information section
3. Line items section describing the items/services ordered
4. Total amount clearly stated
5. Payment terms (use "Net 30" if not specified)
6. Delivery date (include if provided)
7. Standard terms and conditions footer
8. Signature lines for authorized approval

Format the document clearly with proper sections and professional business language.
Return only the purchase order document text, nothing else.
