Most small business owners regard customer service as an unwanted and irritating aspect of their companies - but you can turn this service into a profit-making supplement to your existing business.

Here's how you can earn more profits — even after you have sold your product.

Treat Your Customers with Respect

If you cannot handle all your customers personally, then hire employees who are good at dealing tactfully with your customers.

Happy customers are the best way to bring in new customers - and the cycle can be repeated again and again to grown both your business and profits.

Open a Customer Service Center

If you are dealing in products that require service, then train yourself and your employees on how to service those products - open up a service center on your business premises.

Even though handling complaints might be stressful, your customers will be happy and will always come back to you when they need to make another purchase.

This will not only result in additional profits, but will also establish your company's name as an expert in the market.

Evaluate Your Level of Customer Service

Send in dummy customers to evaluate the level of satisfaction that your employees are able to provide.

Note any improvements that could benefit your business and make your customers happier. Do this on a regular basis, so that your employees do not get complacent.

More satisfied customers simply mean more repeat business.

Consider Customer Service an Invaluable Part of Your Business

You should inject great customer service into your business genes. It is just as important as achieving sales, since satisfied customers will respect you and your business - and that will translate into higher sales and profits.

Do not ignore this vital aspect of your business. Good customer service not only provides you and your customers with mental satisfaction, but will also increase sales and subsequent profits.
