When to Choose Merlin
Professional services (consultancy, agencies, IT services, audit) requiring detailed project costing
Field service (equipment maintenance, installations, IT support)
Bespoke processes that do not fit standard templates
When the budget is constrained
When to Choose SeniorERP
Distribution with complex logistics (multiple warehouses, picking, scheduled deliveries)
You need advanced WMS (waves, cross-docking, location management)
You require mobile SFA for agents (tablet orders, optimized routes)
You want a modern web interface and access from anywhere
Common Limitations
Both ERPs have gaps in modern operations:
EDI with retailers (Carrefour, Metro, Auchan, Dedeman, eMAG)
Omnichannel eCommerce (Shopify, WooCommerce, eMAG Marketplace)
Unified OMS
AI / ML forecasting
Comprehensive B2B Portal for distributors
The Azuvio Smart Layer bridges these gaps for both systems.
Conclusion
Merlin = services and projects. SeniorERP = distribution and logistics. The choice is almost mechanical depending on your vertical. For both, the Azuvio Smart Layer becomes necessary when adding modern digital channels (retail, eCommerce, advanced mobile SFA).
