The business of managing human resource functions efficiently can be very challenging. OneSource HR is an Administrative Services and Human Resource Outsourcing (ASO/HRO) practice that delivers cost-effective solutions to businesses that employ 25 to 500-plus people. Most businesses are already outsourcing payroll, employee benefits and retirement plan services to multiple service providers. Common results of this practice are multiple invoices and information systems, multiple contacts, layers of paper and a great deal of time wasted. Our ASO Model offers the ultimate solution for businesses looking for administrative relief and professional management of their employment and Human Resource practices. By integrating payroll, employee benefits, 401(k) plan requirements and employment administration into a streamlined and efficient system that results in a single point of delivery, our clients can reallocate internal resources toward more strategic initiatives that drive better business results. We maintain the flexibility to allow our clients to elect any or all of the services we provide based on identified needs, creating a personalized “Paperless HR Platform” that streamlines administration and leads to better business results
