With the increasing use of technology in modern times, there is an increasing need to provide technical support, both in the private and the public sectors. Because of the potential high cost of tech support services, many organizations choose to locate their technical support departments or call centers in countries with lower costs to operate, which is called outsourcing. There has also been growth in companies uniquely specializing in providing technical support to other organizations, by using their own call centers and developing specialized knowledge and expertise in the clients' services.

For businesses needing to provide technical support, outsourcing can provide them with the ability to maintain a high availability of service. This comes as a result of peaks in call volumes during the day, periods of high activity due to the introduction of new products and maintenance service packs, and the necessity to provide consumers with a high level of service at a low cost to the business. For businesses needing technical support assets, outsourcing enables their core employees to focus more on their work in order to maintain productivity. It also enables them to utilize specialized personnel whose technical knowledge base and experience may exceed the scope of the business, thus providing a higher level of technical support to their employees.

Countries such as India, Mexico, the Philippines, and others that have the telecommunications infrastructure are highly adept at providing outsourced tech support services to businesses worldwide.
