How do you ask for a testimonial? After the project is done or work it into the contract in the beginning?

Never ask for a testimonial before you complete a project!

Once you’ve completed your assignment and you have a pretty good idea that your client is happy with the copy, you can go ahead and ask for a testimonial. Or, if they write you a nice thank you email at the end of the project, go ahead and ask them if they would mind if you used that on your website.

Just let your client know you’re building out your website and you would love to add feedback from them.
