55-75% of SAP S/4HANA migrations fail. Here's why NeoDonkey doesn't.
For a 50-person company, expect €500K-€2M for initial implementation, plus €200K-€500K for mandatory upgrades every 3-5 years. Annual maintenance is 18-22% of license cost. Total 5-year cost typically exceeds €850K. Hidden costs include consulting, customization, training, and data extraction fees if you leave.
55-75% of SAP S/4HANA migrations fail due to: 1) Underestimated complexity and scope, 2) Data migration issues and dirty data, 3) Custom code incompatibility, 4) User resistance to change, 5) Budget overruns averaging 2.3x initial estimates. Most failures aren't technical, they're organizational and financial.
For small to mid-sized companies (10-200 employees), yes. NeoDonkey covers core ERP functionality: general ledger, AP/AR, inventory, procurement, and multi-company consolidation. What you don't get: industry-specific modules (pharma, aerospace), complex supply chain optimization, or global payroll. But you also don't get the €850K price tag.
Your data is a git repository on your machine. Stop using NeoDonkey and you still have all your data in a standard format any developer can read. No extraction fees, no proprietary formats, no vendor approval needed.
