Regrading VAT, I don’t have a VAT ID. I don’t collect any VAT tax. So there is no way I can provide anything on an invoice referencing VAT.
As a US based company, the United State Internal revenue service doesn’t require me to have a VAT ID or collect VAT tax. So therefore, I don’t do anything at all with VAT.
Here is the US, we don’t have such strict requirements for sales receipts.
Is VAT the thing that you are really needing? I can put the same information from the sales receipt int a different format and call it an “invoice” and save as a PDF if you want and send it to you. However, it won’t contain VAT info.
In the US, what we call an “Invoice” is a request for payment sent prior to purchase. What is called a sales “Receipt” is a proof of payment sent after a purchase. So technically what you are wanting is a sales receipt. However, I can put the word “Invoice” on it and save as a PDF if you want. I can add “end of month” on it if you really need that. I have never heard of that before.
