Many large companies turn to outsourcing to cut costs. In response, entire industries have evolved to serve companies' outsourcing needs. It's true that outsourcing can save money, but that's not the only (or even the most important) reason to do it.
Control capital costs
Cost-cutting may not be the only reason to outsource, but it's certainly a major factor. Outsourcing converts fixed costs into variable costs, releases capital for investment elsewhere in your organization, and allows you to avoid large expenditures. Outsourcing can also make your firm more profitable, since you're able to pump more capital directly into revenue-producing activities.
Increase efficiency
Companies that do everything themselves have much higher research, development, marketing, and distribution expenses, all of which must be passed on to customers. An outside provider's cost structure and economy of scale can give your firm an important competitive advantage.
Reduce labor costs
Hiring and training staff for short-term or peripheral projects can be very expensive, and temporary employees don't always live up to your expectations. Outsourcing lets you focus your human resources where you need them most.
Start new projects quickly
A good outsourcing firm has the resources to start a project right away. Handling the same project in-house might involve taking weeks or months to hire the right people, train them, and provide the support they need. And if a project requires major capital investments (such as setting up networking, system Infrastructure and etc), the startup process can be even more difficult.
Focus on your core business
Every organization has limited resources, and every manager has limited time and attention. Outsourcing can help your organization to shift its focus from peripheral activities toward work that serves the customer, and it can help managers set their priorities more clearly.
Level the playing field
Most organization simply can't afford to match the in-house support services that larger companies maintain. Outsourcing can help organization act "big" by giving them access to the same economies of scale, efficiency, and expertise that large companies enjoy.
Reduce risk
Every business investment carries a certain amount of risk. Markets, competition, government regulations, financial conditions, and technologies all change very quickly. Outsourcing providers assume and manage this risk for you, and they generally are much better at deciding how to avoid risk in their areas of expertise.
