My dentist office, Lester K. Lowe Dental Offices, always remembers to give me a card that says when my next appointment will be. This card just has the name of the dentist office and a couple lines for dates and times.
Dentists offices and doctors offices, and any other company that sets appointments in person (maybe tax preparers or lawyers), can benefit from this business card idea:
Instead of just putting your appointment times on your business card and leaving the back of the business card blank, put your real business card on one side, and the appointment schedule on the other.
This will cost you more, but the results will be well worth it. Double sided business card printing always costs more, but in the end always works out well. If you know of any other companies that this might work for, send some feedback!
