You’ve been talking to a new client about a project. The client has been disappointed with other freelancers, seems to like you. Has lots of work. The client asks for a quote.

You want this project, you want this client. So you think very carefully about the fee.

After a lot of head-scratching and figuring, you finally settle on $2100.

You type up the email, send it off to the client, with fingers crossed.

A few hours later, the client replies to the email:  “Okay. That sounds good. Let’s get started right away.”

Except you notice that, in your email to the client, where you had meant to type $2100, you actually typed $3100. One thousand dollars more.

What do you do now?
