I am a Non-VAT registered UK sole trader that is providing services (web development) to a VAT registered EU business.
My turnover is well below the VAT registration threshold. However, the business I provided the services for are asking for my VAT number because I did not supply one in the invoice for obvious reasons.
I told them that they should VAT reverse charge but they are still insisting they need a VAT number.
I would like to know what needs to be done at this point. Thank you very much in advance.
