I wonder if anyone can help, i get the majority of my income from affiliate marketing, however one network i work with is sending out self billing invoices for one amount but paying a lesser amount.
So for example i will get a self billing invoice for say £1500 plus vat but will get credited with just £800 plus vat. (they pay when they get paid - So the invoice they issue is what i have earned.)
The question is should they not issue a debit note to cover the missing amount or should i issue my own invoice for the diffrence.
There is some issue as whether they have set up self billing correctly
The treatment of VAT is one thing but has nothing to do with the query.
If they raise a self bill, why do they not pay you what the invoice states? That is the question and needs to be answered by them. Until then, your VAT will be wrong anyway, regardless of what method you use.
