4 September 2025 by Marius Bogdan Lixandru

ITFlow is a free, open-source platform designed for Managed Service Providers (MSPs), offering a comprehensive ERP solution for IT documentation, ticketing, and billing. It serves as a centralized hub for managing client information, including contacts, locations, vendors, assets, licenses, domains, and documents, streamlining operations and boosting client satisfaction. Key features include an efficient ticketing system for IT support, advanced invoicing with recurring invoices, quotes, automated reminders, and Stripe payment integration, as well as robust accounting for tracking expenses, income, payroll, and assets. In this step by step guide I will show you how to install ITFlow on your Synology NAS using Docker and Portainer.

💡Note: This guide works perfectly with the latest ITFlow v25.06 release.

I’ve been very honest about this aspect of my work since the beginning: I don’t run any ADS, I don’t require subscriptions, paid or otherwise, I don’t collect IPs, emails, and I don’t have any referral links from Amazon or other merchants. I also don’t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community. It’s something I love doing and have been honest about my passion since the beginning. But I also Need The Community to Support me Back to be able to continue doing this work.
