Calculation / Settlement tool for Events - Excel specialist wanted

We need to have a calculation / settlement tools for events with following specification: - Tool must be very easy to use - Probably Excel is the best tool - but: other suggestions? - there is a general / main calculation for each event divided in following subcategories: 1. Income 2. Fixed Costs 3. Variable Costs 4. Settlement - There are at least 4 parties (companies) giving Input for the calculation. Therefore this input from the external parties must be integrated and aggregated in the main document - Within the categories (Income, Fixed Costs, Variable Costs, Settlement) there are subcategories, for example: Fixed Costs Venue related Rental Power Cleaning Production related Stage ... - The whole process from budget, forecast, final must be reproduced - There must be the flexibility to add or remove any kind of positions (in the examples above: Rental, Power, Cleaning, Stage, etc) Questions: 1. Is Excel the right tool? 2. What are other suggestions? 3. Explain how you would bring in the data from the external parties? 4. Explain how you would guarantee the necessary flexibility (every calculation / settlement looks different)? 5. What would be the right budget? 6. What would be the right timeframe' ## Deliverables * * *This broadcast message was sent to all bidders on Wednesday Aug 22, 2012 4:51:22 AM: Dear bidders, Thank you very much for your input and bids.
