The most common complaint in property management: maintaining the same master data in three systems. In 2026 the answer is not “another tool” but an ERP core — with portal and accounting on top.
Immoware positions itself as a cloud accounting ERP with genuine two-way interfaces to casavi, etg24 and facilioo. casavi delivers tenant and owner communication; after the MANAGBL.AI integration, AI telephony too. Together that is a stack I set up regularly.
Separate roles clearly
- Immoware: properties, contacts, postings, bank, service charges — system of record
- casavi: portal, tickets, notices, self-service for tenants/owners
- DATEV: tax adviser export, consistent chart of accounts
Blur the lines and you get media breaks — and AI trained on wrong data.
What bidirectional really saves
One-way exports from legacy ERPs were the norm for years. Bidirectional means:
- Address change in portal → update in Immoware
- New unit in Immoware → visible in portal
- Cases with status back to ERP for reporting
That cuts double entry and makes AI pre-sorting meaningful — because context is correct.
The AI layer in 2026
Immoware focuses on OCR and semantic document matching; casavi offers AI for tickets and (via MANAGBL.AI) phone assistants. Important:
- AI does not replace accounting review
- Approval workflows before outbound mail to tenants
- DPA with every provider, data in DE/EU
Migration from Immoware24, WOWI or DOMUS
Immoware advertises migration in under two weeks without disrupting operations. Realistically you need mapping, a test tenant and training — but cutover need not paralyse everything over a weekend.
Typical mistakes
- Portal live before master data is cleaned
- DATEV chart of accounts debated only after go-live
- No owner for interface errors (who gets the alert Monday morning?)
Conclusion
Immoware + casavi in 2026 is not either/or but best-of-breed — when the interface is clean and roles are clear.
How I can help
I plan architecture, support migration, wire DATEV/email and add AI pre-sorting with approval where needed. Get in touch when island solutions should end.
