Essential Invoice Requirements
An invoice should contain specific details to ensure prompt payment:
- Unique Invoice Number: Never duplicate invoice numbers. Keep a sequential record (e.g., 2026-001, 2026-002).
- Clear Line Items: Specify the exact headline or story reference along with word counts.
- Payment Terms: State when payment is expected (e.g., "Net 30 days" means payment is due within 30 days of invoice receipt).
