Choosing an HR Outsourcing Company for Payroll Implementation in California

Ask who prepares and checks employee records, historical payroll information and benefit data before the first operating cycle. Identify the test process, approval owners and a contingency if an item is not ready. Compare completed implementation work with a proposal that leaves data cleanup or validation to your staff.

Ask which systems connect, what implementation work is included and who resolves incomplete data. Provide your actual employee locations and current administration arrangements so the provider can explain what applies under the proposed agreement.
