An ERP prototype makes one concrete sub-process clickable before budget flows into a large project. It reduces uncertainty about scope and fit. It neither replaces a full requirements exercise nor the productive go-live. For executives and IT the benefit is clear: you see early whether core workflows can be mapped in the system before price and timeline are locked. Whoever jumps straight into big-bang ERP discovers fit problems late and expensively. Individual ERP needs exactly this early clarification: does the solution fit your processes, not the other way around?

What should a prototype deliver before the large project?

A good prototype answers decision questions, not feature wishes:

• Show whether core workflows can be mapped in the system
• Involve business departments early and collect feedback on real edge cases
• Secure scope and effort for Nuclos Enterprise or a specification
• Create a shared picture of what “done for the core process” means

For that to work, the prototype needs a bounded process slice and measurable goals up front. Without goal setting, the prototype becomes a demo without decision value. Orientation: How do you define ERP goals and scope before choosing software?. Before the build, a rough process modeling helps: make steps, roles, and decisions explicit. The prototype then checks on the clickable system whether that picture holds.

What does a prototype deliberately not deliver?

The prototype is a decision basis, not a go-live. It typically does not deliver:

• full data migration of all master data and histories
• all interfaces to third-party systems
• productive operation with training for the entire organization
• company-wide rollout across multiple departments

Whoever places these expectations on a prototype disappoints themselves. The value lies in early clarification: What belongs in the first productive scope? What moves to phase 2? Which assumptions were wrong? Exactly these questions lower risk before Nuclos Enterprise starts on agreed scope.

What does the Nuclos 48h prototype deliver concretely?

Nuclos offers a 48h prototype: a bounded process in Nuclos, usable technically and functionally as a basis for discussion and planning. Fixed price: 950 euros plus VAT, credited toward follow-on projects, especially toward Nuclos Enterprise. The build is AI-assisted inside Nuclos low-code, not as uncontrolled chat beside the ERP. Business departments click real screens and workflows instead of interpreting requirement texts.

The result feeds the next decision: deepen the specification, request a fixed-price offer for Nuclos Enterprise (from 10,000 euros plus VAT, productive ERP in 30 days on agreed scope), or deliberately postpone scope. An overview of entry paths: Which Nuclos entry path fits your situation?. The prototype is a Funnel A entry for scope clarity, not a substitute for productive operation.

When is a specification instead of or after the prototype useful?

When multiple stakeholders, a tender, or high complexity need clarity, the prototype alone often is not enough. Then a requirements specification documents processes, fields, and acceptance criteria in a structured way. Often the sequence is: clarify goals, sketch the process, prototype, then specification or direct fixed-price delivery. The prototype shortens the specification because core workflows have already been checked on the model. That keeps the later fixed price calculable instead of turning it into an estimate with renegotiation risk.

Why does big bang without a prototype get expensive?

Without an early practical test, assumptions stay unchallenged. Only in the build or after go-live do gaps appear. Change requests and timeline shifts follow. Typical patterns and countermeasures: Common ERP implementation mistakes. A prototype moves that insight forward while corrections still cost little. Process-first instead of module catalog: you check your critical workflow, not a feature list.

For teams that want to extend later themselves, the prototype still remains an entry for scope clarity. Self-configuration and AI in the client belong to Nuclos Workspace. The decision “guided delivery” versus “self-build” should be deliberate, not mixed inside one project phase.

Which next steps make sense?

• Sharpen goals before the prototype: How do you define ERP goals and scope before choosing software?
• Sketch workflows before the build: Why is process modeling the foundation for automation?
• Avoid typical implementation mistakes: Common ERP implementation mistakes
