Wave

Wave is a powerful, completely free accounting platform that is ideal for bootstrapped freelancers and solopreneurs. It offers unlimited income and expense tracking, double-entry accounting, invoicing, and receipt scanning at no cost. Revenue comes from optional, competitively priced add-ons like payroll and credit card processing. Its bank connection feature automatically imports and categorizes transactions.

While its reporting is solid and the core feature set is remarkably comprehensive for $0, advanced features and integrations are more limited than paid competitors. For those seeking a robust, zero-cost foundation, Wave is an unbeatable value and a top contender.
