Automated Invoice Management: Nextcloud, Email & Telegram

This n8n workflow automates the management of incoming PDF invoices stored in a Nextcloud folder (/Invoice/Incoming). Triggered daily at 8 AM, it lists files, filters for new entries, downloads them, attaches to emails sent via SMTP to a specified recipient (e.g., invoice@example.com), notifies via Telegram bot with the filename, and finally moves the processed file to an archive folder (/Invoice/2025/archive).

Key benefits include significant time savings by eliminating manual file checks, downloads, emailing, and archiving. It ensures no invoices are missed with reliable daily scheduling and provides instant Telegram alerts for real-time awareness. The workflow is robust, handling multiple files in one run and using simple configurations for Nextcloud credentials, SMTP settings, and Telegram bot token.

Perfect use cases: Freelancers receiving client invoices, small businesses processing supplier bills, or any operation needing hands-off document routing. Integrates seamlessly with Nextcloud for file storage, standard email for delivery, and Telegram for notifications, making it a low-effort, high-impact automation for business operations.
