It’s a fact that if you are looking for business you can’t afford to miss out on any opportunity. You’ve gone through the trouble of having cards printed, sorted out a website and are careful to publicise your contact numbers for potential customers; so when you are out either put call divert on so that the number switches to your mobile or make sure that you have voicemail on your phone.
Depending on your business it’s not appropriate that you yourself answer every call especially as that stops you working and it is now obvious that you are a one man band irrespective of the picture you are painting on your website and a voicemail or answer machine further reinforces this.
So if you want a human to answer every call then consider hiring a call answering service which will give the impression of a larger company. This will enable you to sort out which calls require your immediate attention and which calls can be relayed to you at the end of the day.
