What Payroll provider does your company use and is it integrated with Oracle HCM?

Summary:

I am curious to know what Payroll provider other companies are using and whether it is integrated with Oracle HCM or not. We are a global company and understand having one payroll across the globe is very difficult. My team currently does payroll for our Canada and US offices, so was wondering what other companies use as their payroll provider and is payroll integrated with Oracle?
