If you are an entrepreneur, the happiness of your customers should be one of your main priorities. The effective use of Facebook allows you the opportunity to get instant feedback from your customers and provide quick support or guidance.

It will of course depend on your business, but if there is a need for customer support, why not use Facebook, too? Depending on the demand you may need a couple of employees to assist in answering questions that are posted.

Chances and risks

Remember though if you decide to offer such a service you need to ensure you satisfy the needs of the customers. If you show that you are committed to their needs and that you take them seriously, your customers will feel appreciated and are more likely to return.
If a customer has something to complain about then this is a good way to get to know about it and please your customers. You may fear a negative impact if your company gets criticised publicly but note that this can take place anywhere online without knowing about (forums etc.). Regard critical posts as an opportunity to monitor and deal with your customers concerns and desires.

Be natural, polite and committed and you will see a customer support page will pay off.
