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.
Software built around
your process
Few companies fit a template. Most of what we build starts from how your operation actually works.
Build trust through
visible results
No hidden costs, no large initial investments. We show involvement, dedication, and the ability to propose effective, well-fitted solutions at every stage.
Tailored business logic
Solutions built around your specific workflows, not generic templates.
Quick support & training
Fast responses and thorough onboarding to keep your team moving.
Complete access & control
Full ownership of your code, data, and infrastructure — always.
Fair pricing
A predictable retainer covering development, support and operations. No surprises, no per-user pricing.
How
we work
Built on open-source foundations, delivered step by step. No lock-in, no upfront risk.
RISK
Validate results before any major commitment.
Satisfied or reimbursed.
100% free & open-source ERP
No vendor lock-in. Modern, modular, and extensible from day one.
No license fees
Your budget goes into features that matter, not platform subscriptions.
You own the code
Full access, full control, full portability. Your software, your rules.
A retainer, not rent per seat
Development, support and operations in one predictable monthly fee that does not rise because you hired five more people.
Step-by-step delivery
Follow progress closely, iterate quickly, and decide when to go further. No upfront commitments.
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.

A relationship,
not a project
We could sell you a fixed-price project, deliver it and disappear. We choose not to. The software your company runs on is never finished — it follows the business — and it is the relationships that last that make your product stronger, because only time lets us understand the operation properly.
BY MONTH
The retainer renews because it keeps paying for itself.
The server, the data and the code are yours from day one: the exit is always open.
A fixed scope ends where the value starts
A specification is written at the moment you know least about the problem. A fixed-price project delivers exactly that, and ends the day your team finally understands what was actually needed.
Knowing the business is what makes the difference
After a few months we know your vocabulary, your exceptions, the peaks in your year and the people who use the system every day. That knowledge does not fit in a specification, and it is what separates a feature that is correct from a feature that is useful.
Fixed price puts us on opposite sides
In a closed project, every change of mind on your side is a loss on ours, and we both end up arguing about scope instead of results. On a retainer, a better idea halfway through is simply the next thing to build.
The system stays alive
Regulations change, integrations break, new Odoo versions land, teams grow. Software that sits still ages fast; yours has someone looking after it every week.
We are measured by outcomes, not by delivery
Because we are still here next month, our interest is not in closing the scope: it is that the process takes less time, that the error stops happening, and that the retainer pays for itself. If that is not happening, it is the first thing we put on the table.

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.
Why a monthly retainer instead of a fixed-price project?
Because fixed price forces every decision at the moment you know least, and from then on each thing you learn becomes a renegotiation. Staying month to month, we accumulate knowledge of your business — the vocabulary, the exceptions, the peaks in your year — and that knowledge is what makes the system keep getting better instead of merely getting finished. It also aligns us with you: continuing only makes sense if the results justify the next month. If a closed scope really is what you want, we will say so plainly in the first conversation — sometimes it is the right call.
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.
