Enter monthly advance invoice for electricity & gas

You can enter it now. When you receive the final bill, you can then enter the difference (possibly as a credit note if there is a refund). You will probably receive an invoice in your personal name, without a vAT number, which means you cannot reclaim the vAT.That's right, the nuance of vAT is particularly important!

A vAT number is required on the document if you want to reclaim vAT.I have here an additional question: I am starting my own grooming salon at the back of my house in July. My current contract expires next month, so I was wondering what the best solution is in this case. Is it possible to have your vAT number added to the invoice if you pay for it from your private account? Or does your contract have to be in the name of the business?
