Logo, Logo GO Wings, Logo Start 3, Logo e-Invoice, Logo e-Ledger and Logo e-Dispatch are names of Logo Software. This is an Ekse Bilisim Software introduction page, not an official Logo page, and it does not claim a reseller authorisation.
Logo e-Invoice is described on Logo’s product page as an electronic invoice. The page says the solution follows the Revenue Administration’s UBL-TR standard and data-transfer procedure, and that it is legally equivalent to a paper invoice.
The same page lists digital storage, a storage service and integration with existing software. Which ERP or integrator account is required is settled in the quote. This page is not a credit or price list.
