Give every provider the same location inventory
Include offices, remote employees, temporary work arrangements and expected expansion. Ask how location changes are reported, reviewed and reflected in payroll and policy processes. General nationwide language is not enough; the provider should describe how named states are supported.
Check operational depth and legal boundaries
Compare registration coordination, pay groups, notices, leave administration, policy supplements, recordkeeping and manager support. Confirm when qualified legal or tax advisers are involved. The employer should retain oversight rather than assume the provider accepts every state-specific responsibility.
