Freelance developer rate calculator
Work backward from your target income, taxes, expenses, and real billable capacity to find a rate that actually supports your business.

Comparison
diffbill vs Harvest
Choose diffbill when your billing source of truth is shipped work in GitHub. Choose Harvest when your team still needs timesheets, hour approvals, and classic time-tracking workflows.
Comparison
diffbill vs Toggl Track
Choose diffbill if you want consultant invoices built from merged pull requests and outcome-focused descriptions. Choose Toggl when simplicity in timer tracking matters more than GitHub-native billing.
Comparison
diffbill vs InvoBee
Choose diffbill when you bill from shipped code in GitHub and want PR-sourced line items without rebuilding the month from timers or notes. Choose InvoBee when you want a general-purpose freelancer suite with time tracking, expenses, and projects across any kind of work.
