Invoice Best Practices
- Itemize Everything: Break down services/products into clear line items.
- Include Tax: Always calculate and display applicable sales tax.
- Payment Terms: Clearly state when payment is due (Net 15, Net 30, etc.).
- Discounts: Apply discounts before tax for standard accounting practice.
