Multi-currency and multi-organization support works natively from a single installation

Small community of ~50-100 active contributors — far fewer than Odoo or ERPNext
UI feels like a well-built 2015 application — functional but not modern
Finding experienced VIENNA Advantage developers is difficult outside Austria and Germany
Documentation is thin for manufacturing and advanced accounting modules
No native mobile app — only responsive web interface
Self-hosting requires sysadmin skills and 2-5 days for initial setup

Purpose-built for SMBs with 10-250 employees - not a stripped-down enterprise product
SAP brand credibility with banks, investors, and enterprise customers
10,000+ global certified partners give you local implementation options
Multi-currency, multi-language, multi-company support built in
Strong manufacturing and MRP module for batch and discrete production

Never self-implement - partner costs add $25K-$150K to total project cost
User interface feels dated compared to NetSuite or Business Central
Add-on costs for e-commerce, advanced reporting, and industry modules surprise buyers
Limited native e-commerce integration requires third-party connectors
