In compliance with the requirements set by the Revenue Administration (GİB), businesses obligated to use e-Invoices must present their invoices electronically. These invoices must be transmitted to the GİB portal within a week, following the defined criteria. Non-compliance is considered a violation.

After checking the e-Invoice obligation in the SAP system based on the tax identification number, the invoice sending method and scenario are determined. The sales document, accounting, purchasing, and sales invoices are created using the XSLT structure and standard fields in the cockpit. No additional fields are needed, and the setup is standard, thus avoiding integration problems and errors.

Different from e-Invoice, export invoices require transmission to the Ministry of Customs. Mandatory fields on the invoice include delivery terms, KAP quantity, transportation method, and HS code. These fields are fed from the SAP sales distribution module screens and material master data.

E-Archive Invoice is a method of invoicing non-e-Invoice obligated recipients and is automatically created using the same structure and fields as e-Invoice. The submission period for E-Archive Invoice is set to 1 month, and the invoice report must be uploaded to GİB by the 15th of each month. For past-dated invoices not yet sent, an additional report is generated after submission to rectify any irregularities.

This system digitally stores legally mandated journals and ledgers. Approval is given to the finance authority with an electronic signature, and records are organized in a standard format. The journal is created by combining accounting documents from the SAP system and operator information.

Integrator firms transmit signed certificates to GİB, from where access to old ledgers is also available. After printing from SAP, ledgers are saved in ".TXT" file format. Once the recording is complete, a trial run is removed at the customer's request, and the relevant financial period is closed.

E-Waybill, a system used to track goods movements electronically, is now regulated as an electronic document in accordance with Article 230, Paragraph 1, Clause 5 of the Tax Procedure Law No. 213. It has the same legal value as the existing "dispatch note."
