Invoice Ninja is a source-available application for invoices, quotes, projects and time tracking, built with Laravel and Flutter. Freelancers and small businesses use it to bill clients, record expenses and tasks, and take payments. Topics in the repository include expenses, kanban task boards and electronic invoicing.

Two setups are offered. The hosted version is a software-as-a-service product that is ready in minutes with no server to manage, while the self-hosted version gives full control over hosting and infrastructure. According to the README, all Pro and Enterprise features of the hosted app are included in the source code, and self-hosted installs work with the desktop and mobile apps.

Apps exist for iPhone, Android, F-Droid, macOS, Windows and Linux via Snap or Flatpak. Self-hosted options include a server or VM, Docker, Cloudron, Softaculous, Elestio and YunoHost, with Stripe and Postmark suggested as providers. A Go SDK and an API are available. The license is listed as a custom source-available one, with a white-label license for removing branding.

Ever Gauzy is an open business management platform aimed at collaborative, on-demand and sharing-economy businesses. It brings ERP, CRM, human resource management, applicant tracking and project management together with employee time and activity tracking, and is part of the larger Ever Platform.

Main features include HR management with time tracking and performance monitoring, CRM, ERP, project and task management, sales management, financial and cost management with accounting and invoicing, and inventory, supply chain and production management. A dashboard gives an overview of metrics such as company income, expenses and employee bonuses, and the platform offers headless APIs. Topics also mention payroll, expenses and bookkeeping.

The company also builds Ever Teams, a work and productivity app in a React and React Native stack that connects to the Gauzy APIs. Gauzy is written in TypeScript and licensed under AGPL-3.0, and can be self-hosted. It suits agencies, startups and distributed teams that want to run an internal business system without paying per seat for several SaaS tools.

Midday is an open-source business assistant for freelancers, contractors, consultants and solo entrepreneurs. It brings functions that are usually spread across several tools into one system, covering time tracking, invoicing, matching receipts to transactions, secure file storage and an overview of finances. The code is TypeScript and is licensed under AGPL-3.0.

According to its README, time tracking records live work on projects, Magic Inbox matches incoming invoices and receipts to the correct transactions, and Vault stores contracts and agreements. Financial data can be exported as CSV files for accountants. An assistant provides insights into spending patterns and helps locate documents. Invoicing was listed as an upcoming feature in the README at the time of the snapshot.

The architecture is a monorepo using Bun, React, Next.js, Supabase, shadcn and Tailwind CSS, with Tauri and Expo for apps. Bank connections use GoCardless in Europe and Plaid or Teller in North America, and the hosted service runs on Supabase, Railway, Vercel and Cloudflare. The README says documentation for local development is still being written.

Invio is a self-hosted invoicing application built around simplicity. The workflow is to create an invoice, share a secure link with your client and get paid, without menus to dig through, setup wizards or extra features that most freelancers and small businesses never use.

Clients receive a secure link and do not need an account, which avoids the usual back and forth about logging in. The interface includes a dashboard, invoice creation, invoice lists and settings, and the project provides a live demo and documentation with a quick start guide. Because you host it on your own hardware, invoice data stays under your control and is not affected if a SaaS vendor changes its pricing or shuts down.

Invio is written in TypeScript and released under the Unlicense, which places the code in the public domain. The README says there is no subscription, per-invoice charge or hidden fees, and the author accepts optional donations. It suits freelancers and small teams that want straightforward invoicing without a monthly bill.
