What is Invora?

Invora is a self-hosted invoicing system for freelancers, agencies, trades and small businesses, sold as a one-time purchase with full source code rather than a monthly subscription. It handles estimates, invoices, branded PDFs, part-payments, receivables ageing, recurring billing that cannot double-draft the same cycle, clients with CSV import, tax rates and a reusable item catalogue. Outbound features run on your own credentials and ship switched off: emailed invoices and reminders through your SMTP server with a send log, and an .ics feed of due dates. Beyond the invoicing itself it includes a REST API with revocable keys, webhooks, an MCP endpoint for AI assistants, two-factor authentication, OIDC single sign-on, scheduled backups, an audit log and GDPR anonymisation. It runs on plain PHP 8 with MySQL or SQLite on ordinary shared hosting, needs no framework or build step, and never phones home.

What is B2Billing?

B2Billing serves as an automated billing system designed to provide you with complete oversight while functioning autonomously. It efficiently converts logged hours into compliant invoices, manages their distribution, and tracks overdue payments, ensuring that recurring invoices, receipts, and collections are handled effectively, keeping receivables updated. Each invoice is meticulously generated and scrutinized before sending, with a human oversight feature ensuring that no document is dispatched without your direct consent. A specialized billing dashboard presents the status of all invoices, organizing them into categories such as awaiting approval, pending, blocked, or issued. This cutting-edge solution is developed by OpsAgents AI, aimed at creating a billing experience that aligns with your specific requirements. With B2Billing, you can enjoy peace of mind knowing that your billing processes are both efficient and reliable.
