    Ownware

    $99 one-time
    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.
