A computer process for determining an insurance premium comprises: validating username/passwords; receiving payroll data asynchronously or scheduled in real time; extracting payroll data required for premium determination; detecting the presence or absence of fraud related to the payroll data; applying state jurisdictional inclusion and exclusion rules applicable to workers' compensation premiums; transferring premium to a billing system for debiting the customer account. The elements to the system comprise a payroll system configured with an accounting/bookkeeping software where regular payroll data resides; a utility that permits reading payroll accounts residing in the accounting/bookkeeping software; an Internet connection having a browser; a filter to allow extraction of payroll data exclusive of other payroll deductions; a rules engine customized to a particular remote payroll system that includes a mechanism to separate different occupations and a billing system.
