What our customers say

From mid-market to global enterprise: companies across industries map their processes with Nuclos.

The rollout was agile: Novabit implemented defined outcomes and flexibly adapted where we deviated. We have ERP software that fits our processes, stays affordable, and has no license fees.
Jürgen Dehner Secretary General · ARCD
Customer satisfaction comes first for us. The simpler the processes, the better. With Nuclos we fully automated and transparently mapped our leasing contract management. That reduces sources of error and saves time. The rollout was a milestone toward paperless company bike leasing.
Victoria Mittelbach Head of Platform Development · BusinessBike
Thanks to the modular design we can map processes including all information optimally. Novabit implements new requirements quickly. Interfaces to project management and site administration plus automations reduce the load on our planners and increase scalability.

Individual ERP at a fixed price

We help you understand and plan processes, with more than 25 years of experience.

With Nuclos Enterprise as a productive full system on agreed scope, typically in about 30 days and always at a fixed price, you get the worry-free package. The 48h prototype optionally shows scope and ROI first for only EUR 950 plus VAT. The requirements specification creates clarity before procurement or go-live. No long-term lock-in: you stay flexible and independent.

Processes and build

Processes and build:

Rigid modules and often a separate AI chat on the side. Processes adapt to the software.

Processes and build:

The ERP is built around your processes. Low-code and AI speed the build in one system.

Time to value

Time to value:

12 to 18 months before the first individually productive system. Scope grows, budget is spent long before ROI is possible.

Time to value:

Productive operation in about 30 days on agreed scope. Fixed price, planned go-live, immediate ROI.

Project risk

Project risk:

Long projects with uncertain outcomes. Budget overruns and delayed go-lives are the norm.

Project risk:

First prototype in 2 days with a clear exit if Nuclos is not a fit. Everything at a fixed price with clear delivery guarantees, so risk stays calculable.

Sovereignty

Sovereignty:

Per-user licensing, proprietary code. Unclear data residency and difficult exit options.

Sovereignty:

Open source: source code and data stay with you. Cloud or on-premise, made in Germany.

Frequently asked questions

Clarity before you decide: answers to the questions we hear most often.

What is Nuclos 5, and who is individual ERP for?
Nuclos 5 is the platform for individual ERP systems: software built around your processes, not a fixed module catalog. Typical for mid-market companies whose workflows do not fit standard ERP, or that want to leave Excel and workarounds behind.
How does AI help build the ERP today?
AI supports creation and extension: Nuclosian helps with modeling, screens, and rules, in configuration mode and for superusers only. Reading business data follows the signed-in user's permissions, without a separate approval. Writing starts as soon as the model calls the tool. The low-code framework remains where configuration happens. That applies to self-build with Nuclosian AI and to AI-assisted delivery of the 48h prototype and Nuclos Enterprise.
How do Nuclosian AI and Nuclos Enterprise differ?
Nuclosian AI: your team builds and extends itself. Solid knowledge of company workflows and process planning is required. Nuclos Enterprise: we deliver a productive full system on agreed scope, typically in 30 days, at a fixed price. Both use the same Nuclos 5 platform and can be combined. A Nuclos Enterprise project can later be extended by you in Nuclosian AI if you want.
When is the 48h prototype the right entry?
Where scope or feasibility is still unclear and you need something tangible before a large project. In two days we model a subprocess for you as a clickable prototype at a fixed price of EUR 950 plus VAT, and when you commission Nuclos Enterprise, we credit the amount and continue the prototype.
Does Nuclos charge per-user license fees?
No. Nuclos is open source without classic per-user licenses. You invest in implementation, support, or Nuclosian AI packages, optional hosting, or consulting. Fixed prices are on Nuclos Enterprise, Nuclosian AI, and the 48h prototype.
Can I run Nuclos in the cloud and on-premise?
Yes. The same platform in our cloud or on infrastructure of your choice (private cloud or on-premise). We are happy to clarify data control and operating model in a personal conversation; both paths stay GDPR-compliant and made in Germany. Special requirements for documentation and traceability in regulated industries can also be implemented.

Individual ERP, tailored to your needs.
