We used to call it sub-contracting but now it’s BPO or business process outsourcing. The main benefit of turning to a process outsourcing is the expertise. Take for instance the security guards that you hire for your business that you employ whether in the office or in the warehouse. The outsourced security guard is already trained with license which relieves you of those hassle. Another example is the repairs or construction of the structure. Hiring a sub-contractor is much convenient than getting your own workers for the job. The only catch in BPO is the high cost of service contract.
