Quotation Expert vs Invoice Ninja
Invoice Ninja is open-source and powerful — but the free plan has a 20-client cap. Here's the full comparison.
Invoice Ninja is a strong open-source invoicing tool loved by developers and technical users. However, the free plan is limited to 20 clients — after that you need to self-host or pay. Quotation Expert is unlimited on the free plan and includes a full offline Android app, payroll, and delivery notes that Invoice Ninja does not have.
