I have made my fair share of presentations in my day and the one thing I have learned is, make a template that everyone else can edit. While beautiful, perfect pages are great, if the designer is required every single time someone wants to change a figure or budget line, you’re doing it very wrong. Templates are invaluable to business to keep things moving and if done right, they can be pretty darn good looking as well.
Here is one example of a pretty great template that is completely editable in either ppt or google and still looks terrific. (I have loads of these. They seem to be pretty popular hahha)
