All market statistics point to IT as the most common type of service outsourced today. In terms of specific functions, software application development comes out on top. App maintenance is in second place, followed closely by data centers.
Apart from IT, smaller businesses most commonly outsource accounting and digital marketing, mostly due to a lack of in-house staff trained to perform these functions. Other typically outsourced functions include call services and customer support, which are usually delegated to global centers in India and the Philippines.
