ITFlow: open-source customer support

About ITFlow

ITFlow is an open-source documentation, ticketing and accounting platform for small managed service providers. It addresses the problem of scattered client information and expensive per-seat MSP tools by consolidating common needs into one platform that the provider controls.

It manages clients, contacts, vendors, assets, licenses, domains, SSL certificates, passwords, documentation, files, networks and locations, and adds ticketing and billing with quotes, invoices and expenses plus Stripe integration for online payments. Alerts cover domain and SSL expiry and renewals, and a client portal lets customers manage quotes, invoices and tickets themselves. The topics also mention lead management and project management.

ITFlow is written in PHP and licensed under GPL-3.0. The recommended self-hosting method is an install script on Ubuntu or Debian, with manual options in the documentation, and the README says managed hosting is coming soon. A demo, docs and forum are available. It suits small MSPs and IT consultancies that want an all-in-one system without licensing costs.
