Open
by Nature
We build the software your company runs on — and hand you the keys. Open-source ERP, automation and custom development on infrastructure that belongs to you, not to a vendor.
Own your infrastructure,
own your future
Every year, more of your company runs on software you rent. Your customers, your prices, your processes, your entire operational history — sitting on someone else's servers, under someone else's terms. Owning the infrastructure your business depends on is no longer an IT detail. It is a strategic decision, and it gets harder to reverse the longer you wait.
The companies still in control ten years from now are the ones building their own foundations today.
Software you rent
RentedCosts that only move one way
Per-seat pricing punishes growth. Every new hire, every extra module, every annual increase is decided somewhere else and simply applied to you.
Data you don't actually hold
Your operational history lives on servers you can't inspect, in jurisdictions you didn't pick, under terms that change without asking you.
Someone else's roadmap
Features get retired, APIs get closed, versions get discontinued. Your plans wait on a vendor's release notes.
No realistic way out
The longer you stay, the more of your process is locked inside the platform. Leaving turns into a migration project nobody wants to sign off.
Infrastructure you own
YoursYour server, your call
On your own hardware, on your premises, or in an EU datacentre under an account in your company's name. The credentials are yours: we operate the server, we don't own it.
Your data, in your hands
Full database access, backups you hold, and a GDPR position you can demonstrate in an audit instead of taking on trust.
Your code, permanently
An open-source core plus the modules we build for you. There is no key anyone can turn off. If we disappeared tomorrow, your system keeps running.
AI and automation on your terms
Analyse and automate on top of your own data, without handing years of business history to a third party you don't control.
Illustrative figures based on common per-seat SaaS pricing. On the first call we run the numbers against your actual stack — including the case where staying put is the right answer.

The power of
Open Source
Proprietary software creates invisible chains — recurring fees, vendor roadmaps, and data you don't fully control. Open source breaks all of that.
Your business shouldn't depend on a vendor's
survival, pricing, or priorities.
Full Transparency
Every line of code is readable and auditable. No black boxes, no hidden logic, no surprises.
No Vendor Lock-in
Switch providers, self-host, or extend freely. You are never held hostage by a platform.
Community-Driven
Backed by thousands of developers worldwide. Battle-tested, continuously improved, and free forever.
Built to Last
Open-source projects outlive companies. Your investment is protected regardless of what happens in the market.

answers
The questions every company asks us before moving to infrastructure of their own.
Isn't running our own system riskier than a SaaS?
We handle hosting, monitoring, updates and nightly backups — the same operational work a SaaS does. And the server can genuinely be yours: a machine on your premises, or a hosting account in your company's name with the credentials in your hands. We operate the server; we don't own it. The difference shows up the day you want to move — to another provider or in-house: everything is already within your reach.
We already run another platform. Can we migrate?
Usually yes. We import customers, products, invoices and history, run both systems in parallel until your team is comfortable, and only then switch off the old one.
How long before we see something working?
A first working version in weeks, not quarters. We deliver in small steps you can validate, so you decide whether to continue based on results rather than promises.
What happens if we stop working with O93N?
You keep the server, the database and every line of code. Any developer who works with open-source ERP can pick it up from there. That is the entire point of building it this way.
Do we need an IT department for this?
No. Most of our clients have none. Your team uses the system; we take care of everything underneath it.
Where does our data physically live?
On EU infrastructure by default, or on your own premises if you prefer. You choose, and you can change your mind later without renegotiating a contract.
