An invoice for hours is a critical professional document that freelancers use to bill clients for work accurately based on the hours worked. It specifies the tasks completed, the hours worked, and the corresponding charges calculated at an agreed hourly rate. This helps freelancers validate their work while ensuring transparency with clients. For example, a web developer who spends 15 hours on a project at $60/hour can clearly show how the final bill was calculated. Hourly invoices are essential in industries requiring flexibility, time-specific deliverables, and mid-project adjustments.

Tip
Using hourly invoices not only reinforces trust between freelancers and clients but also promotes professional communication and accountability.
