The Parsek e-Fatura (e-Invoice) and e-Arşiv (e-Archive) module digitally issues, sends, receives, and archives your invoices via a GİB (Turkish Revenue Administration) approved integrator (Uyumsoft). It fully automates e-fatura/e-arşiv processes, which are mandatory for companies with over 3 million TL in turnover as of 2026.
Regulatory Compliance is Risk Management
If you are an e-Fatura or e-Arşiv taxpayer and are still issuing paper invoices, a GİB penalty is imminent. Moreover, as of 2026, the limits are decreasing: turnover above 3 million TL → e-fatura is mandatory; invoices issued for over 30.000 TL to non-taxpayers, and over 5.000 TL to taxpayers must be e-arşiv.
