Five hand-approved projects in our catalog replace QuickBooks. They are mainly operations, also personal finance, invoicing and accounting. ERPNext has the most GitHub stars (40.8K). Tick what matters to you and the list re-sorts so the closest fits come first. Invoice Ninja is source-available (Elastic-2.0), not open source.
