Why does a management fee need an invoice number?
Because it is your company's sale to the building. Across the EU a VAT invoice carries a sequential number, based on one or more series, that identifies it uniquely (VAT Directive 2006/112/EC, art. 226); Cyprus, Germany and Greece each add rules on content and retention. Confirm the local requirements with your accountant. Domera numbers the series and produces the PDF; it does not file your VAT return.
