Manager

Manager is a 100% free, full-featured desktop accounting application for Windows, macOS, and Linux. It offers professional double-entry accounting, invoicing, inventory management, bank reconciliation, and comprehensive reporting-all without any fees, subscriptions, or user limits. It can be installed locally for offline work, though a cloud-hosted version is available for a fee. Its feature set rivals many paid products.

The main limitations are the lack of automatic bank feeds and a smaller community. For budget-conscious solopreneurs who are comfortable with manual data entry and want a powerful, permanent, free accounting solution, Manager is an outstanding and often overlooked option.
