1. The illusion of square cells and circles drawn by eye
In PowerPoint or Excel a round table is a vector shape with no metric scale. On screen it looks as though 15 tables fit comfortably, and then the setup crew walks in and the tables hit the columns and the exits are blocked.
2. The hidden cost of copying data by hand
An event coordinator who goes from a spreadsheet to a PDF, then to kitchen lists and finally to paper loses between 8 and 12 hours a week on mechanical work that purpose-built software does in two clicks.
3. What high-spending clients read into your documents
A couple or a company paying €15,000 for a banquet expect an impeccable scale proposal with their name on it, not a screenshot of spreadsheet cells in primary colours.
