How do I set up accounting and finances for my TEDx event?

Rules differ from country to country, so the way you set up your event's finances and accounting system depends on where you live. You may set up a nonprofit. If you do so, do not call it anything related to TED, TEDx or TEDx[name]. You need to pick a separate name for your nonprofit. (You can also consider running your TEDx event through an existing non profit.)
