I have been asked to invoice a client for an image used as the cover of a book and am not sure how to price it.
The client I have worked with previously, the editor am connected to on social media so have a reasonable relationship, they asked me a year and half ago to submit some images for possible use and I thought they had changed their mind until I received an invitation to the book launch featuring one of my images, I got in touch and they said I should invoice, we had at no point discussed a price, a quick look up of pricing on Alamy suggests something around $600 depending on print run ( am not sure what that will be) but am pretty sure they will not go for that, the book is published or just about to be so its not as though they are in a position to argue but I would rather avoid that.
Am I worrying too much and should just bill them about $600?
