Clichés make a speaker sound like their competition.
“We give good customer service” is a meaningless platitude.
Referrals require specifics that highlight distinction.
Share a single system you have for addressing a single need your customers have.
Explain the benefit your clients receive because of this particular aspect of your customer service.

I have a system for assessing the security of a WordPress website. The first thing i do is log into the back end and see what plugins, themes, and core files need to be updated. This is the most common exploit, much like not updating apps on your phone and computer. After that, i like to run an initial scan of the system using various tools to see if there are open doors that could be exploited. Often times website are hacked and users don't even know it because the hack is hidden from plain site.
My clients obtain great benefit from this service knowing their website is not hijacked and is working for them, not some nefarious hacker.

When a prospective client comes to me who has not filed a tax return for several years I request that they authorize me to get tax transcripts from the IRS. I charge for that service, however its less than the customer would pay in penalties if income reported to the IRS is not on their filed tax return.
