A good flyer should answer the following questions:
Who? Your flyer should contain your business name, phone number, email address, your name and either your location or if you're mobile, the territory you service.
What? It should briefly outline your detailing services with a Quality Checklist such as; Polish & Wax By Hand, Clean & Vacuum Interior, Clean Tires & Wheels, Clean Windows, etc.
When? It should clearly identify the days and hours you are available.
Where? It should identify where all of the work will be done. If you're mobile then you could use a sub title such as, “Cars Polished And Waxed...At Your Location”
Why? It should identify the fact that your detailing service is a convenience that will save your customer time and money. And that having their car detailed will help to protect their investment.
