Ledger Brief Take
Crater fills the gap for practitioners who want invoicing control without vendor lock-in, offering genuine self-hosting alongside standard cloud deployment. The open-source foundation means you can customize workflows and maintain data ownership, but you'll trade the polish and integrations of established players like FreshBooks or Wave for that flexibility.
