The price charged for one unit of a product or service—the cost per item or hour.
Unit price is what you charge for one unit of whatever you're selling. If you bill $150 per hour, that's your unit price for time. If you charge $25 per square foot, that's your unit price for area. Unit price multiplied by quantity gives you the line item total on an invoice.
Invoice line items typically show:
Example: Labor | 12 hours | $85/hr | $1,020
Your unit price needs to cover your costs, overhead, and desired profit. Consider what competitors charge, what the market will bear, and how you want to position your business. Some businesses use different unit prices for different services or client types.
