What actually makes a freelancer trustworthy?

I've been thinking a lot about this while building my freelancing playbook for web developers.

We talk a lot about:

• getting clients
• positioning
• pricing
• proposals
• outreach

But there's another question underneath all of it:

• Why does a client trust one freelancer over another?

• Two developers can have similar technical skills.

• One gets the project and eventually gets referred to someone else.

• The other struggles to get past the first conversation.

I'm starting to think the difference is often in the "boring" stuff:

• How you communicate.

• How you ask questions.

• How you structure the proposal.

• How you handle pricing objections.

• How you set expectations.

• How you invoice.

• How you close out a project.

• How easy you make it for the client to work with you.

The code gets you into the conversation.

• The way you operate determines whether they want to work with you again.

I'm curious what other freelancers think:

What was the thing that made a client start treating you like a professional rather than just "the person building the website"?

I'd especially love to hear from people who've been freelancing for a few years.
