I'm new to freelancing and have made a bit of a blunder. I did some work for a public business and I invoiced them thinking I needed to add VAT.
They emailed me to say how much they were going to pay me and it didn't include VAT. I showed it to my business savvy friend who said they were right as I'm not VAT registered and they'd probably worked that out on my behalf. I emailed them back to say Thanks and all good. Then I got another email saying they were going to pay me the amount including VAT. Should I fess up and pay back the extra? Its not much, but don't want to get into trouble
