Most new freelancers tend to jump right into client work without setting up systems or clear processes for their clients. They think they'll just figure it out as they go.
Here's the problem: As they take on more clients, they raise their prices. They see what other freelancers are charging and somehow feel entitled to earn the same amount.
You CAN'T raise your prices and deliver a beautiful design through a crappy process.
Your pricing doesn't just account for your skills, designs and time. It accounts for the experience the client gets.
