Gusto is a people-operations tool for payroll, contractor payments, onboarding records, and basic HR workflows. For WaveSOC, the key question is not whether payroll software is popular; it is whether the business has reached the point where pay dates, worker records, tax forms, and handoffs need a repeatable system.

It belongs in the stack once the owner can describe who is being paid, how often, what records must be kept, and how payroll data should connect back to bookkeeping.
