SurePayroll

SurePayroll (acquired by the massive Paychex conglomerate) is a fiercely agile, highly specialized, and deeply targeted SaaS platform. It operates as the absolute apex predator of "Micro-Business and Nanny/Household Payroll." While standard software targets 20-person companies, SurePayroll built a massive empire by targeting the massive, highly underserved market of 1-to-5 person micro-businesses and wealthy families hiring domestic workers. The absolute core superpower of SurePayroll is its "Household Employer (Schedule H) Tax Engine." If a family hires a full-time Nanny, they legally become a 'Household Employer' and owe complex 'Nanny Taxes' to the IRS. SurePayroll is mathematically engineered to completely abstract this terrifying legal liability, autonomously calculating and paying the Nanny, while preparing the specific IRS Schedule H for the family's personal tax return. Because it completely eliminated the massive fear of IRS audits for micro-employers, offering unparalleled household payroll logic, massive mobile convenience, and deep accountant portals, it is the inescapable standard for Nanny payroll, solo-preneurs, and tiny mom-and-pop shops.
