Merits of specialisation include:

• Being able to provide a focused, specific and personalized service to their customers means that sole traders can thrive
• solitary traders become experts/specialists at their jobs and this improve their productivity
• There are lower costs involved compared to providing a wide range of different services and goods.

Note: although individual traders specialise in the provision of a service or good, they tend to necessitate a variety of management skills since they cannot afford to hire specialists (and hence do not benefit from the division of labour).
