Every site must be protected and lay out any policies you may have.  Make sure you head to https://thecontractshop.com/collections/freelancers-small-businesses 
to protect your website.  

By listing your late, deposit, and non-negotiables here, you and your clients are more on the same page, know what to expect from each other, and then you are also both protected.  At the end of the day, you need to protect your business.  Do not launch your site without completing this section!
