I think it depends on the size of company that ZP wants to target. I did a payroll processor evaluation for my startup 2 years ago and the upfront pricing and lighter (less time consuming) sales process that surepayroll offered compared to paychex and ADP was one reason we chose surepayroll over those companies.

Surepayroll also offered much better online tools and better pricing than either Paychex or ADP at the time. Now that Paychex has acquired Surepayroll it's good to see another online friendly option being built. Now if somebody would just build an online friendly way of managing 401Ks for small businesses.
