Hiring — Contractor vs Employee, ESOP Basics, Payroll if Scaling

Know the legal and tax difference between hiring a contractor and hiring an employee in India. Understand when ESOPs make sense for a one-person OPC and how to set them up. If you do hire an employee, know what payroll, PF, ESI, gratuity, and TDS-on-salary look like operationally. Hiring is dependency injection with tax implications. A contractor is an external service (interface contract, no shared state); an employee is an in-process module (shared state, lifecycle hooks like PF and gratuity). ESOPs are vesting schedules — exactly the same mental model as a NodeJS package's lockfile, except the vested instances are humans with feelings and tax events. The classification question (contractor vs employee) is the encapsulation question: are you treating this person as a black box with a service contract, or are you treating them as part of your internal architecture with shared lifecycle? The answer determines the legal treatment, and the legal treatment must match the operational reality. Misalignment is the failure mode.
