Context
WinMentor is the classic Romanian ERP favored by accountants: on-premises, perpetual licensing, highly stable, and low upfront cost, but dependent on local servers and in-house IT.
NextUp ERP is a cloud subscription model, requiring no servers or IT staff, featuring native mobile apps and a B2B portal.
5-Year TCO Comparison (30 users, distributor)
WinMentor: €18k license + €6k server/Windows/backup + €8k/year partial in-house IT × 5 = €40k + 12% annual maintenance × €18k × 5 = €10.8k. Total ~€75k. (Excluding mobile and B2B, which require additional modules).
NextUp ERP Standard: 30 × €35 × 12 × 5 = €63k + €12k implementation + €6k integrations + €4k/year admin × 5 = €20k. Total ~€101k (Including mobile + B2B + cloud + backup).
The ~€26k difference over 5 years buys you mobile access, a B2B portal, local cloud hosting, automated upgrades, and zero IT overhead.
