What Bizuno is
Bizuno is a free, open-source ERP you install on your own server. It handles accounting, customers and sales, vendors and purchasing, inventory, banking and general ledger, quality management, and the everyday paperwork a small business runs on. The goal is a single, honest toolset for the kind of business that’s outgrown a spreadsheet but doesn’t want to rent a SaaS ERP for the next decade.
Bizuno is web-based: you install it on a machine you control — a Linux VPS, a Windows box, a Mac, a Docker host, or an ISPConfig-managed server — and everyone who needs it opens a browser. No per-seat license. No minimum-term contract. No data leaving your network unless you decide it should.
Where it came from
Bizuno grew out of PhreeBooks, an open-source accounting package that’s been in continuous use since 2008. PhreeSoft (Dave Premo and a small circle of contributors) rebuilt it as Bizuno in the mid-2010s to widen the scope from accounting into full ERP territory — inventory, purchasing, quality management, PhreeForm templating — while keeping the self-hosted, AGPL ethos that made PhreeBooks useful in the first place.
The 71-article manual on this site is the accumulation of roughly a decade of that work. The forum you see at /community is new; the software underneath it is not.
What we care about
Self-hosting without shame. Most ERPs assume you want to hand your books to a vendor. We don’t. If your data is sensitive, your margins are private, or your industry is regulated, you should have a good open-source option. Bizuno is that option.
Low-drama software. We ship when things are ready, we don’t chase trends, and we keep the plugin count low on our own site for the same reason we keep the dependency count low in the product. Fewer moving parts, longer uptime.
A readable codebase. Bizuno is PHP, because PHP is what small-business hosting actually runs. The code is boring on purpose. You should be able to open a module, read it, and extend it without learning a framework.
One community, two surfaces. Code lives on GitHub. Conversation lives on /community. If a conversation produces a bug, it becomes a GitHub issue. If an issue produces a question, it becomes a forum thread. Neither surface swallows the other.
Who’s behind it
Bizuno is maintained by PhreeSoft (a small shop run by Dave Premo in the United States) plus a rotating cast of contributors who have sent patches, written docs, answered forum questions, or translated strings. The Contributors page names everyone we can find — if we missed you, tell us.
PhreeSoft also offers commercial hosting, consulting, and custom development for businesses that would rather pay a human than run their own server. Those services are described on the Support page. They don’t change the product; Bizuno is AGPL and will stay AGPL.

Bizuno is licensed under the GNU Affero General Public License v3 — you can use it, modify it, and run it as a network service, provided that any modifications you ship are offered back under the same license. The full text and a plain-English summary are on the License page.
