Frequently Asked Questions

Why should freelancers charge fixed project rates instead of hourly?

Fixed-fee pricing decouples your income from time, rewards efficiency, gives clients predictable upfront budgets, and prevents earning caps as you get faster.

How much buffer should I add for client revisions?

Most successful freelancers add a 20% to 30% time buffer to account for onboarding, asynchronous communication, revisions, and project handoff.
