There are two main purposes for this study. The first aims to provide a comprehensive review on the past literature review on outsourcing in the foodservice business sector by identifying the commonalities and filling in the gaps. The second purpose is to contribute to the limited research works that cover this field of study. This study adopted a qualitative research method with data collected through physical interviews with F&B business owners based on their knowledge, attitudes, perspectives, and needs on outsourcing to online food delivery services. In most research works, motivators, trends, risk, benefits, and relationships are discussed. The research on business owner's perspective in relation to outsourcing food delivery service is found to be scarce. The findings in this research work suggest that there are three main driven factors to the business owners' behavioral intention to outsource food delivery service to third-party online food delivery service provider. These factors are listed as increase of revenue, wider customer reach and expand customer base. The findings propose that business owners should consider and pay close attention to the changes in the consumer preference as it still remains dynamic, if they want to remain competitive in the foodservice industry. On top of that, this research work also provides insights and recommendations to third-party online food delivery service providers. This is one of the few research works that study the determining factors for restaurant businesses to outsource to online food delivery service providers. The continuous and drastic changes in the restaurant business reflects the worthiness for further researches considering the booming potential in the foodservice industry where online delivery service is taking up a big part of the market share. In order to reduce cost and maximize profit, many restaurants are asserting effort in outsourcing to online food delivery service providers. It may be difficult for business restaurant owners to explore the opportunities or challenges associated with the outsourcing to online food delivery service in the existing studies and literature.
