Monster files that take minutes to open, and sometimes don't. Data scattered across countless copies. Formulas nobody dares to touch. Numbers with no audit trail. It works, until the day it doesn't.
The one person who built the model has no time anymore or is leaving.
The auditors are asking questions about the Excel and the process that you can't answer.
Budget season means three weeks of copy-paste.
You've grown. So has your Excel — in complexity and in number.
Consolidation by hand, every month, from files sent by email
Version confusion, nobody is sure which numbers are current
Key-person risk: one expert holds the whole model in their head
No trail of who changed what, when, hard conversations with auditors
One governed platform, everyone works on the same numbers from anywhere, right in the browser
Reports that are always up to date, with data from all your files, without a single copy-paste
Your models live in the business, fully documented, not in one person's head
Secure: versioning, database, permissions, workflows, and complete change tracking
Continuing with Excel as before is not a solution!
Your workbooks, and the years of thinking inside them, stay exactly as they are. Nooxl Apps turns them into governed, browser-based enterprise software.
Your experts keep modeling in Excel. And everything can be exported back to Excel at any time with formulas, formatting and charts, not just values.
No migration project, no re-implementation of your logic in someone else's system. We adapt to your process, never the other way around.
Your models become browser-based applications with permissions, workflows, and audit trails, ready for auditors, boards, and growth.
Most companies think their only options are living with the Excel chaos or rebuilding everything from scratch. There's a third way.
Nooxl Apps also come as ready-made industry solutions: proven modules built from best-practice Excel models, tailored to your organization within days. Because everything runs on Excel, every piece of logic stays transparent, understandable, and adaptable by your own team. Off-the-shelf software that adapts to you, not the other way around.
For project developers, housing companies, asset managers, real estate funds, and banks. From property-level cash flow to balance sheet planning, all modules from one source and ready to be linked together.
Headcount and personnel cost planning across departments, locations, and entities, including pay scales and salary grades. One number that HR, controlling, and management agree on, with scenarios instead of Excel versions.
With all of your models, together with our industry specialists. Through rapid prototyping, you see your first working app in days, not months.
No black box, no proprietary scripting language. Your business teams model in Excel, and Nooxl Apps turns it into transparent, secure enterprise solutions, including Excel risk management: central storage, versioning, and control over every business-critical file.
Portfolio & asset management, funds, one current view of every asset.
Fund management and planning with full auditability.
Client models that scale beyond the partner who built them.
Budget planning across portfolios, projects, and entities.
Long-horizon planning with governance your investors expect.
And one promise behind all of them: we adapt to your process, never the other way around.
Consolidation, distribution, and collection happen on the platform, not in inboxes.
Management reporting on numbers that are current by definition, not by deadline.
Every figure traceable to who entered it, when, and why. Auditors get answers, not shrugs.
Permissions decide who sees and edits what, your most sensitive models stop travelling by email.
Teams, entities, and partners work on one set of numbers, with workflows instead of reminders.
A guided implementation project isn't mandatory, but it's the fastest route. From go-live on, the platform is yours: your team adapts and extends the models on its own, in Excel, without having to ask us. If you'd like, our training courses get your team up to speed.
We look at your most business-critical workbook together. No preparation needed on your side.
