What do publishers earn? - Paperight/website GitHub Wiki

As a publisher, when you add a document to Paperight for print-on-demand sale and for copy-licensing, you choose your rights fee per copy in dollars. (In line with most print-licensing deals, we recommend charging the equivalent of 5–15% of your conventional publication’s RRP. But it’s up to you.)

We pay you 80% of that license fee, and Paperight keeps a 20% commission. There’s no exclusivity, and you can take down your documents at any time.
