Description

Invora is self-hosted invoicing and billing software bought once rather than rented. It covers estimates that convert to invoices in one click, branded PDF documents, a public link each client opens without an account, part-payments with outstanding balances by client and by age, recurring invoices that always land as drafts for review, a reusable item catalogue and configurable tax rates. Invoices and payment reminders can be emailed through your own SMTP server, with every attempt recorded in a send log, and due dates published as a calendar feed. Invora records payments but never processes cards: you paste your own payment link, which appears as a Pay button on unpaid documents only.

Description

This open-source web application is designed to facilitate the management and creation of invoices in an intuitive manner. While it focuses on a single function, it excels at delivering that service effectively. Every element is positioned intuitively for user accessibility. You can handle invoices with unique serial numbers and save drafts for later editing. Additionally, it allows you to generate neatly formatted PDF versions of your invoices for professional presentation. Invoices can also be created automatically on a scheduled basis. You can manage billing from any location with internet access. Furthermore, the application enables programmatic management of customers and invoices directly within its interface. The vibrant community of developers around this application is continually enhancing its features, ensuring that users benefit from ongoing improvements and updates. This collaborative effort contributes to a robust and evolving tool for all users.
