🚀 Overview

Easy Invoice is a full-featured SaaS package that empowers freelancers, micro-businesses, agencies, service providers and small enterprises to create and send invoices quickly and manage simple accounting — across platforms (Android, iOS and Web). With a unified backend and optional self-hosted deployment or cloud SaaS model, it offers flexibility and scalability for multi-tenant usage or white-label customisations.

Users can generate invoices on their phones, track payments, manage expenses, and access dashboards via web. Admins can manage subscriptions, tenants, branding, payment gateways, and analytics — making the package ideal for launching a SaaS invoicing platform or offering it internally to a team.

Target users: SaaS founders, agencies wanting branded invoice portals, freelancers seeking mobile invoicing, and small businesses wanting unified billing & accounting across devices.
