Hello to all,
A foreign publication emailed me to enquire the use of an image I posted on my blog for their upcoming printed edition and offered their rate upfront in the email.
In the follow up, they requested me to provide an invoice (as they said would be great if I can provide one, although they sounded not necessary though).
Being a random blogger with no business entity registered, I would like to be advised how should I come up with an invoice (in what format)?
Also how necessary is an invoice in such transaction?
Thanks for any help and advice.
