Modular Austrian ERP with CONTBUCH accounting and CONTWEB portal.
Executive Summary
CONTHAUS is a modular Austrian ERP suite for property managers and real estate trustees. Its CONTBUCH accounting module and CONTWEB portal deliver solid BAO-compliant bookkeeping and EBICS banking, but there is no visual workflow builder, no AI layer and no auditor portal.

Legend
- Built-in
- Fully part of the vendor's own product, developed and maintained in-house. No extra contract, no data sync, one support line.
- In development
- Not yet usable, but on the active engineering roadmap with a confirmed release window. Relevant for multi-month rollouts that can plan around it.
- External vendor
- Delivered by a separate vendor via integration, add-on or sync. Expect additional licence fees, a second support relationship, and data flowing across two systems.
- Partial
- The feature technically exists, but only at checkbox level: enough to tick the requirement, rarely enough to solve the underlying day-to-day workflow.
- Not available
- Not part of the product. No integration, no roadmap commitment — the workflow has to happen outside the platform.
Strengths of CONTHAUS
- Native CONTBUCH accounting with BAO-compliant archiving
- Native EBICS banking and meter/heating cost database
- CONTWEB portal for owner and tenant self-service
Weaknesses of CONTHAUS
- Only basic ticketing via CONTMANAGER task notes
- No AI layer — neither voice agent nor in-app copilot
- No auditor portal, no service directory, no WEG voting engine
Operational differences
01
Process-driven workflows instead of static inboxes
Every ticket in Units-Master triggers an executable, multi-step Standard Operating Procedure (SOP) — no manual tag assignment, no ping-pong between staff members.
02
Native voice AI agent, not a third-party tool
Inbound phone calls are handled entirely by the native voice AI agent: emergency dispatch, intake and ticket creation — autonomously, 24/7.
03
In-app copilot Werner AI: contextual and action-capable
Werner AI is not a generic chatbot. It knows property history, summarises units, prepares accounting data and executes actions directly.
04
Embedded service directory, wired into workflows
The /directory connects local tradespeople, plumbers, HVAC technicians and auditors directly to the automated ticket workflows — no media breaks, no manual coordination.
When each fits
Choose Units-Master when…
- You want executable SOP-driven workflows instead of task lists
- AI-assisted telephony and native service directory are strategic priorities
Choose CONTHAUS when…
- You need a modular Austrian ERP with proven BAO accounting
- Your team already runs the CONTHAUS module stack (CONTBUCH, CONTMANAGER, CONTWEB)
