For decades, payroll has been one of the most manually intensive systems within a company. Even as companies expanded across borders, introduced flexible work structures, and began operating in dozens of countries simultaneously, payroll remained rooted in outdated assumptions: one jurisdiction, one tax system, one calendar, one set of rules. Meanwhile, the world of work changed faster than anyone predicted. Teams went global overnight. Compliance accelerated in complexity. Regulations shifted again and again. Remote work blurred national boundaries. And companies that once had simpler, local payroll needs suddenly carried the operational burden of distributed multinational organizations.Payroll infrastructure, even within newer cloud-based systems, did not evolve to meet this reality. It continued to rely on manual checks, spreadsheet reconciliation, and human intervention to correct errors after they occurred. Automation existed, but only at the edges. The core of payroll still required constant maintenance.At Plane, we saw the widening gap between what companies needed and what payroll systems offered. The more global a company became, the more payroll turned into a monthly firefight for HR and finance teams. It was no longer a back-office function. It was a recurring operational risk. This is the problem self-driving payroll solves. It is not simply faster payroll. It is payroll that manages itself, adapts to change automatically, and functions as a living system rather than a manual workflow.
