Everyone here: I think the Magic Budget Template is now ready to use. To use it, start with the documentation – everything is, or should be, in there. Starting from now, this is the new default how to do a budget (and we need to stick to it to enable company-wide cash flow controlling). Let me know in this thread what’s missing or does not work.
(Still no progress on the Magic Spreadsheet, but that’s the final step for me and @anu now: aggregating the project budgets into the company-wide cash flow plan.)
