The time report form automatically calculates billable hours from your schedule. Click days to customize hours, add notes, and generate professional invoices with detailed timesheet attachments.

What is a Consulting Invoice?

A consulting invoice bills clients for professional services, typically charged hourly or daily. Unlike fixed-price invoices, consulting invoices include detailed time breakdowns showing exactly when and how long you worked.

Step 1: Add Time Report

Start by clicking "Add Time Report" in your invoice form.

This opens the time tracking interface that automatically calculates your billable hours based on your work schedule.

The time report form turns a month of timesheet data into a professional invoice in 2 minutes instead of manually entering 20+ line items.
