1.5.14 Invoice Ninja

Invoice Ninja is a free, open-source invoicing, expenses, and time-tracking application for freelancers and small businesses, offering features like custom-branded invoices, recurring billing, online payments via 40+ gateways, project and task management, and expense tracking

Invoice Ninja is by far the most comfortable invoice system that I have used so far for my small freelance business in the hospitality industry. It has more features that I will ever need but it makes invoicing employers just so streamlined and easy. Instead of manually making all your invoices, sending emails, keeping track of payments, due dates, manual payments and more. Invoice Ninja makes this all a smooth experience for both you and the person that needs to pay you.
