Startups and growing companies reach the same decision point at some stage: when do spreadsheets, point solutions, and manual coordination stop being enough? And what comes next, without triggering an expensive, large-scale ERP project?

When does ERP make sense?

Three signals show that the time has come:

Duplicate work and data gaps. The same data is maintained in multiple systems. Order details live in a spreadsheet, invoices in an accounting tool, project status in another app. When these systems fall out of sync, errors follow.

Growing team size. From roughly 8 to 15 employees with responsibilities in purchasing, sales, production, or project work, manual coordination becomes a full-time job. Processes that worked informally with five people need structure.

Early compliance requirements. GoBD-compliant document archiving, e-invoicing, or industry-specific documentation require a system that keeps a proper record.

The problem with standard ERP for growing companies

Classic ERP systems such as SAP Business One or Microsoft Business Central offer a broad feature set that growing companies do not need for 70 to 80 percent of it. The result: high license costs, long implementation times, and a system that is hard to adapt after go-live.

Per-user license costs also scale directly with growth. A company growing from 5 to 20 employees pays four times as much, regardless of whether the software is actually used any better.

Why individual ERP adds up differently for startups

Nuclos is not a standard product. Instead of a predefined feature set, we build the ERP around your actual processes. That has three concrete consequences:

No per-user license costs. Costs arise from development and customization, not from every new team member. A company with 30 people instead of 10 does not automatically pay more.

Open source without lock-in. Nuclos is built on AGPL-licensed source code. You receive the complete source code of your ERP instance. No vendor can lock you out or change the terms.

Process-oriented setup. You start with one process, such as order processing or project management, and expand step by step. No restart, no running two systems in parallel for months.

The entry path for growing companies

If you are not yet sure what your first ERP process should look like, start with the 48h prototype: a clickable sub-process in two days, fixed price of 950 euros plus VAT. The prototype shows how Nuclos maps your workflows before budget and scope for the main project are set.

If you already know what needs to be built, start directly with Nuclos Enterprise: go-live within a month on an agreed scope, fixed price starting at 10,000 euros plus VAT.

For companies with their own IT team who want to build and iterate themselves, Nuclos MCP is available.

What stays in place as the company grows

Nuclos installations grow with the company. New modules, additional users, and changing processes are integrated into existing instances rather than rebuilt from scratch. The investment in the core system pays off across multiple growth phases.

Source code and data remain your property at every point in time.
