Look into other services, such as call forwarding, for your store phone and your cell phone, as well as voice mail for your cell phone and beeper service.
Make sure your telephone system can handle the incoming call traffic with no busy signals or long unanswered rings.
If you have a home business, make sure your office is separate from the rest of the house. Kids yelling or dogs barking will not make a good backdrop for telephone conversations with clients.
Are you confident that your telephone system and etiquette are as client-friendly and as efficient as they should be? If not, try implementing some of the recommendations covered here. If you do, you are likely to see an increase in sales and a better bottom line in your equipment rental business.
