I have been trying to figure out how to post the VAT adjustment for Uber Eats for a while now and have only got as far as knowing that I need to use the Reverse Charge mechanism, but to do this I need Uber Eats VAT number which is a struggle in itself to find. Anyone got it?

From what I have read, this seems to be an issue people are having UK wide. I have only just started with this company and never had to deal with Uber Eats before, but the previous bookkeeper has been using a journal entry to log the sales etc. 

If I am to open Uber Eats up as an EU supplier, can anyone explain what the process is after that?

Any input would be appreciated - I have spoken to our Accountants regarding this issue and they have been less than helpful (simply copied & pasted information that I have already read online).
