Edward McCarroll noted: >>I've been tasked to find an appropriate host for a payroll application ... Hi Ed, Seriously? Payroll on a web host? Wow. I would recommend either buying an app for a well-secured in-house box ... or outsourcing the entire function. There are a number of companies that will handle outsourced Payroll, HR, and other functions. I believe their clientele is mostly small to mid-sized companies. Sometimes it can be a good move to outsource a function and have it handled well. Hmmm. A quick googled stat claims that "58% of companies with fewer than 500 employees outsource their payroll function ... and 28% of companies with 10,000+ employees." Just sounds like a safer route to me. HTH, RonL.
