Is there a difference between an invoice that states a bank transfer and an invoice that is sent after payments for confirmation? Or are both valid invoices to submit for your expenses?For my social security contribution (quarterly), I received a transfer by post. Only confirmation on My Xerius account that it has been paid, not with another confirming invoice. Whereas I have submitted my start-up costs as a confirming invoice.
My question is therefore specifically about social security contributions, but it is also useful for other expenses. So that there is no more uncertainty about this for me, once and for all.
Thanks in advance!
