Most small businesses, probably due to the lack of employees or capital, poorly respond to customer calls and enquiries. They dreamt about making their company big, but have no time take calls or respond to e-mails from customers. This often results in vanishing of these companies as most customers turn their back to them.
Maintaining a constant communication is not so difficult. You can use a variety of techniques for making sure that you want to talk to the customer, now or later. You can use instant answer messages, automated e-mails, answering machines, alternative cell phone numbers, call centers or other answering services, voice mail, call forwarding, and so on. There are also a variety of customer contact softwares and CRM solutions available which can help you in automating the customer communication process.
Most customers do not show interest to call back unanswered companies; especially when you are not only the one to offer a product or service. Always remember winning any market start with winning the minds of customers.
