Food Delivery Platform Financial Model

I am creating a budget for Food delivery platform (generally a bit like Bolt or wolt business model), there are around 10 key dynamic inputs and i need in Pre launch stage, and then post launch Quarters as stages, so that there is clear Input page for variables, output that is monthly, Stage based and annual. Details of Profit and Loss and key driver assumtions vs reality (reality to be entered later) and comparison in profession way and easy to export to powerpoint or pdf. ANd collapsaple up and down P&L in general level both for variable costs and income before gros profit and under it classical Fixed costs around 10-20 lines, Groupes as (Personnel) and then with + possible to open line by line. Relatively simple modelling. Need classig stage by stage andf monthly cash flow budget and P&L. I will provide own "rough" excel but it may have logical or formula errors and input are not all clearly in same place. Delivery time around 1 week, most likely 2-3 rounds. after my comments /ammendmends. in english
