Freelance Invoice Template — Hourly & Project-Based

Freelancers have unique invoicing needs compared to product-based businesses. This freelancer invoice template is specifically designed for service professionals who bill by the hour, by project, or by milestone — with flexible line items that accommodate all three billing models.

The template includes separate sections for time-based billing (hours worked × hourly rate) and project/deliverable-based billing (flat fee per item), as well as an expenses section for billable costs such as travel, software subscriptions, stock photography, or subcontractor fees.

A running total section aggregates all line items, applies any applicable discounts or early payment terms, calculates tax, and presents the final amount due clearly. The payment terms section supports net-15, net-30, and immediate payment options, with a late fee clause that many professional freelancers include to encourage on-time payment.

The template also includes a "Services Rendered" summary section that briefly describes what work was completed during the billing period — particularly useful for retainer clients who appreciate transparency about what activities their monthly fee covered.
