Wave

Free accounting software from Canada, acquired by H&R Block for $537M in 2019. Positioned as the alternative to QuickBooks for freelancers and micro-businesses that can't justify a paid accounting subscription. Distinctive for its genuine forever-free accounting/invoicing (competitors moved everything to paid). Monetizes through payments (2.9% + 60¢), payroll ($20-$40/mo), and advisor services. Popular with side hustlers, freelancers, and micro-businesses under $50K annual revenue.
