A client recently asked me to create a template for a pitch deck: a few different slide layouts, simple charts/graphs, etc. For myself, I have built a number of decks using InDesign because I like the level of control that I get. For this project though, my client is not very technical and would be extremely overwhelmed trying to update a deck in InDesign. The client asked for a PowerPoint template but is open to other solutions if they are a better fit.
My question DN, is what technologies do you use to design and share pitch decks when a non-technical client will need to make updates to it?
