Property development feasibility
Land, construction, financing, sales or lease-up assumptions structured for clear scenario comparison.
Financial modelling
Financial models that also work as operational systems
XLS Experts builds structured financial models and commercial planning systems for projects where timing, costs, financing and scenarios need to be understood clearly — and often updated as the project evolves.
More than a static spreadsheet for the board pack
Many financial models are also operational systems. They need month-by-month timelines, dependency logic, staged costs, financing drawdowns, occupancy or revenue assumptions, version control and scenario comparison.
We do not position this as generic accounting support. We build models and planning tools that help commercial teams evaluate options and manage project economics with confidence.
Where project economics become hard to manage
Signs the current process needs attention.
Feasibility assumptions are buried in undocumented cells
Scenario comparison requires duplicating entire workbooks
Cash-flow timing is hard to reconcile with financing
Only one modeller understands the structure
Planned versus actual reporting is manual and late
Board and lender packs take too long to refresh
What we can build
- Project costing and feasibility models
- Property development modelling
- Cash-flow forecasting
- Scenario and sensitivity analysis
- Loan and interest modelling
- Investment evaluation and budgeting
- Pricing and margin analysis
- Monthly project timelines with dependency logic
- Planned versus actual reporting and management dashboards
Example applications
Project cash-flow and drawdown planning
Month-by-month views that connect costs, revenue timing and funding requirements.
Investment and margin evaluation
Structured models for pricing, contribution and return metrics that stand up to commercial scrutiny.
Live project tracking layer
Connect the model to actuals and dashboards so management sees drift early — not only at month-end.
Possible technology and architecture
Excel remains the primary environment for many financial models because it is auditable and familiar to finance stakeholders.
Where multiple users, permissions or live actuals matter, we add database storage, controlled inputs and dashboard outputs.

How we deliver modelling systems
Understand the current process
We map how work actually happens today — who uses the system, where data comes from, and what slows the team down.
Identify the right level of modernisation
Not every process needs a full rebuild. We recommend the simplest approach that solves the business problem reliably.
Build and test the solution
We deliver working software early, refine it with real users, and validate edge cases before go-live.
Support implementation and ongoing improvement
Training, documentation and a clear path for enhancements so the system keeps matching how you work.

Can you improve an existing model rather than rebuild it?
Yes. We regularly audit and strengthen existing models — clarifying structure, reducing risk, documenting assumptions and adding scenario controls — when the commercial logic is sound.
Do you provide accounting or bookkeeping services?
No. We build commercial models and planning systems. Day-to-day accounting remains with your finance team or accountant.
Can models support lender or board packs?
Yes. We design outputs that are clear, version-controlled and suitable for external review, alongside working models for the project team.
How do you handle version control?
Through disciplined workbook structure, clear assumption sheets, naming conventions and, where needed, shared storage or a database-backed scenario library.
Can scenarios feed a dashboard?
Yes. Once scenarios are structured, summary metrics can drive management dashboards for faster comparison.
Discuss your modelling project
Share the decision you need to support, the timeline of the project, and how assumptions change today. We will propose a model structure that is clear and maintainable.
