Merlin ERP Licensing Model
Prodigy Software sells Merlin on a perpetual license per module + annual maintenance fee (15-20%) model. The hosted version features a monthly subscription per user, requiring no initial investment.
The modular approach means a small company pays significantly less than a large one — however, every activated module adds extra cost.
Scenario 1: Small Company (15-30 employees, 5-8 ERP users)
Modules: Accounting + Inventory + Sales + Procurement.
| Cost | Year 1 | Year 2-5 /year | Total 5 years |
|------|--------|----------------|---------------|
| Merlin License (4 core modules) | €7,500 | 0 | €7,500 |
| Implementation & configuration | €5,500 | 0 | €5,500 |
| Annual maintenance (18%) | 0 | €1,350 | €5,400 |
| Server + OS + SQL on-premise | €3,500 | 0 | €3,500 |
| IT admin (0.2 internal FTE) | €5,000 | €5,000 | €25,000 |
| User training | €1,500 | 0 | €1,500 |
| Subtotal | €23,000 | €6,350 | €48,400 |
5-year TCO: ~€48,000 (~€1,000/user/month).
Scenario 2: Medium Company (50-100 employees, 15-25 users)
Modules: all core modules + HR/Payroll + Production + Project Management.
| Cost | Year 1 | Year 2-5 /year | Total 5 years |
|------|--------|----------------|---------------|
| Merlin License (7 modules) | €20,000 | 0 | €20,000 |
| Implementation & customisations | €16,000 | 0 | €16,000 |
| Annual maintenance | 0 | €3,200 | €12,800 |
| Server / cloud hosted | €5,500 | €1,800 | €12,700 |
| IT admin (0.5 FTE) | €12,000 | €12,000 | €60,000 |
| Training + retraining | €3,000 | €1,000 | €7,000 |
| Subtotal | €56,500 | €18,000 | €128,500 |
5-year TCO: ~€128,000 (~€1,430/user/month).
Scenario 3: Large Company (120-250 employees, 35-55 users)
Modules: complete suite (including Service, Fixed Assets, extended web portal).
| Cost | Year 1 | Year 2-5 /year | Total 5 years |
|------|--------|----------------|---------------|
| Merlin License (full enterprise) | €50,000 | 0 | €50,000 |

| IT admin (1 FTE) | €24,000 | €24,000 | €120,000 |
| Training + documentation | €5,500 | €2,000 | €13,500 |
| Subtotal | €130,500 | €38,500 | €284,500 |
5-year TCO: ~€284,000 (~€1,380/user/month).
Hidden costs to consider
1. Major upgrades: Prodigy releases major versions every 3-5 years. Cost: 25-40% of the initial license.
2. .NET Customisations: €75-130/hour. A medium customisation = €2,500-7,000.
3. Third-party integrations: e-invoicing (e.g. ANAF - the Romanian tax authority) via partners, custom EDI, e-commerce connectors = €1,500-5,000 each.
4. Data preparation: migration from the legacy system = €3,000-12,000.
5. Extended support: optional, +25-40% above standard maintenance.
5-year TCO Comparison (Medium company, 20 users)
| ERP | 5-year TCO | Observations |
|-----|------------|--------------|
| Merlin ERP | ~€128,000 | Modular, flexible |
| CRIsoft ERP | ~€135,000 | Robust production capabilities |
| Charisma | ~€145,000 | Advanced retail/finance features |
| SeniorERP | ~€125,000 | Cloud + native WMS |

Conclusion
Merlin ERP offers a competitive TCO in the mid-market segment, particularly for companies that do not require all modules from day one (the modular model lowers initial costs). However, pay close attention to modern integrations — where Merlin lacks native coverage, costs can rise significantly.
