What do the invoices and agreements look like?

Invoices, credit notes and agreements are produced as PDFs in the reader's own language, with what an accountant expects on them: a VAT summary, the exemption wording where it applies, page numbering and your logo. Names in non-Latin scripts print correctly. Your invoice numbering series is read-only: gaps are possible, duplicates are not. Every download is checked against the reader's access at the moment they click, and every download is recorded.
