A free invoicing and job estimation application is available for small businesses, sole traders, or anyone who sends invoices to clients. This application allows users to create an account quickly and with ease, without any contracts or subscription fees. Users can generate unlimited quotations, invoices, and manage collaborations and payments indefinitely. With this app, users can seamlessly connect with customers through online invoicing and receive notifications when invoices are opened or paid. The user-friendly web interface supports online account management. Key features of the application include a beautifully designed interface for iPhone and iPad, the ability to send estimates or quotations instantly, create invoices on-the-go, and connect with payment gateways like PayPal and Stripe for direct payments. Additional features like a task timer, team collaboration, product and service management, automatic reminders for late payments, and mobile applications for both iOS and Android further enhance usability. The technology stack supporting the application includes Angular JS, Ruby on Rails, SLIM, SCSS, and RSPEC. The application is also complemented by social media channels including Facebook, Twitter, and Instagram, with modest followings. The decision to sell the business is due to a lack of funds necessary to sustain the application and its operations. Despite its robust feature set and social media presence, financial constraints have necessitated this sale.
