If PowerBi is not a must and if we are capable of reading your inputs in proper way and you need a solution on a permanent basis (one or more users in the group) my cloud based solution could be the right one for you.
1) Powerful OLAP based BI platform accepting data from different sources via ETL module (data adjustments).
2) Robust, secure, modular and fully scalable business modelling.
3) Business model adjustable to the end-user needs; multilingual – with pre-prepared reports and KPIs.
4) Supporting all four stages of a business cycle: planning-reporting-analysing-adjusting – bigger/more complex the organisation, bigger our value added.
5) Pre-designed (e.g., “what if”) and on the fly analysis included.
6) Excel as bi-directional slient-server end-user.
You can use it (1) inside our DB in cloud (under MS Azure); (2) more demanding business models can be set-up in their own DB in our cloud or (3) set up your own DB in your cloud (highest costs).
Details and demonstration on request. Quotation is /hour.
Best way would be to show you in live web session via TV, Skype or similar. Let me know.
