Systems, integration & web applications
A cashflow model need not remain an isolated Excel file. We connect models to your existing IT, automate recurring analyses and, where needed, build web-based applications — up to a complete system solution.
Connecting to existing systems
A continuous data flow instead of isolated files: we connect your models to the systems where your data already lives.
- Interfaces to ERP, PMS & portfolio systems
- Import of leases, actuals & master data
- Database & API connectivity (SQL, REST)
Automation & reporting
Recurring analyses with no manual rework — models update themselves and reports are produced at the touch of a button.
- Automated model updates & consolidation
- Standardised investor & management reporting
- Power Query, VBA & script automation
Web-based systems
When Excel reaches its limits: bespoke web applications for input, calculation and analysis — centralised and in the browser.
- Dashboards & interactive cashflow tools
- Multi-user access & permissions
- Central portals instead of scattered files
The rare combination of institutional real estate experience and formal training as an IT specialist (IHK) lets us deliver both the domain logic and the technical implementation from a single source — from the Excel model to a production web application.

A clear model structure, complete documentation and easy extensibility — usable by your in-house team too.

Frequently asked questions
Answers to the most important questions about our cashflow-modelling services.
A bespoke Excel model that maps all cashflows of a property or portfolio — rental income, operating costs, financing costs, taxes and exit. It forms the basis for investment decisions, financing and investor reporting.
We model all common real estate asset classes: residential, office & commercial, logistics, developments, real estate funds as well as debt and mezzanine structures. Specialist assets such as hotels or care homes are also possible.
A standard cashflow model is usually completed in 2–4 weeks once all documents are available. Portfolio models can take 4–8 weeks. We agree the schedule bindingly before the project starts.
The model covers: full rental development (incl. indexation, vacancy, incentives), operating costs, maintenance and CAPEX, financing structure (senior debt, LTV, DSCR), return metrics (IRR, NPV, MOIC, cashflow waterfall) and a scenario analysis with three scenarios.
Yes, we offer model audits for existing Excel models — regardless of who built them. This includes error analysis, plausibility checks and, where needed, reworking. Maintenance agreements for ongoing updates are also possible.
Yes. Alongside classic Excel models, we can connect them to existing systems on request — such as ERP, portfolio or database systems — and automate data imports and reporting. When Excel reaches its limits, we also build web-based applications with central access, permissions and interactive dashboards. Thanks to IHK training as an IT specialist, the domain logic and the technical implementation come from a single source.
After the initial consultation we prepare a binding fixed-price quote — tailored to scope, complexity and asset class. There are no hidden costs.
