Posted in chat for traffic but here for relevance
I'm going to do some voluntary web design and development work for a charity, I'm not going to charge for it but having read some horror stories about people's work not being valued when working for free I thought that sending out invoices (with 100% discount) would be a good way of reminding the client that what they are getting is worth something.
I also think it would be good practice for if/when I start doing freelancing. And it would set a professional tone to treat it like that.
Do you think that would be ok? And are there any laws that say I can't do this would get me in trouble with HMRC?
