Two popular ERPs for companies with 50-500 employees, but with very different philosophies. Cost, implementation, community, vertical fit — compared without diplomacy.

Why we are comparing these two
For a mid-sized company (50-500 employees) in the SEE region that has outgrown entry-level accounting software, the real market choice is almost always between Charisma ERP (local, dominant in RO/SEE) and SAP Business One (global, SAP's mid-market offering). Both cost similar amounts to implement, but differ enormously in philosophy.
Total Cost of Ownership (TCO) — estimated
For an 80-user implementation, multi-company, on-premise, over 5 years:
Charisma ERP:
Licenses: 60-120k€
Implementation (consultancy + customisations): 80-180k€
Infrastructure: 25-50k€
Annual maintenance (~20%): 12-24k€/year × 5 = 60-120k€
5-year TCO: ~225-470k€
SAP Business One:
Licenses: 90-160k€
Implementation (local SAP partner): 120-250k€
Infrastructure: 25-50k€
Annual maintenance (~22%): 20-35k€/year × 5 = 100-175k€
5-year TCO: ~335-635k€
Cost Verdict: Charisma is 30-40% cheaper in terms of 5-year TCO for the same scope. SAP B1 is more expensive per license and more expensive to maintain.
*Indicative figures for a typical distribution/manufacturing company. Varies significantly by vertical and partner.*
Statutory Reporting and Localization
Charisma: ✅ Native localization for the Romanian market. e-invoicing, SAF-T, VAT journals, D300/D394/D406 (local tax filings), local payroll — all working out-of-the-box without add-ons.
SAP B1: ⚠️ Localization available through specific country packages + add-ons from local partners. It works — but adds cost, complexity, and dependence on a partner for legislative updates regarding ANAF (the Romanian tax authority).
Vertical fit
Charisma — strong verticals in SEE:
Multi-store Retail (DIY, fashion, food)
FMCG Distribution with field agents
Banking (Charisma Core Banking — unique in the market)
Leasing & insurance
Regional medium-scale manufacturing
SAP B1 — strong verticals globally:
Discrete manufacturing (components, automotive)
Technical distribution (industrial supplies)
Multinational subsidiaries (when HQ uses SAP S/4, B1 is requested for subsidiaries)
Community and ecosystem
Charisma: Regional ecosystem — consultants, partners, developers — concentrated in RO, BG, GR. If you move operations to Germany, the Netherlands, or the UK, the support ecosystem drops dramatically.
SAP B1: Global ecosystem — 70,000+ customers worldwide, partners in 150 countries, marketplace with thousands of add-ons. If you are expanding internationally, SAP is the safer bet.
Modernisation and API
Charisma: REST API exists (Charisma API Manager) but adoption is lower. Limited public documentation — you depend heavily on the implementation partner.
SAP B1: Service Layer (REST), DI API, Integration Framework — mature, public documentation, active Stack Overflow community.
Honest Verdict
Choose Charisma if:
You operate exclusively in RO/SEE
You are in the banking/leasing/utilities/multi-store retail verticals
You want a lower TCO and local consultancy
Local tax compliance is your #1 priority
Choose SAP B1 if:
You are part of a multinational group using SAP at HQ
You plan to expand internationally in the next 3-5 years
You want a large ecosystem of add-ons and global developers
You have complex discrete manufacturing (multi-level BOM, integrated MES)
Smart Layer — the third option
For 60-70% of companies performing this exercise, the often ignored third option is: keep your current ERP/accounting software and add a Smart Operations Layer (Azuvio) to handle operations (OMS, EDI, SFA, B2B portal, BI, CRM) — without changing the accounting core.
It costs 5-10% of a Charisma or SAP B1 TCO, goes live in 4-8 weeks, and allows you to maintain the flexibility to migrate to a heavy ERP only when you *truly* have no other choice.
