How to Issue an e-Invoice? Who is Required to Transition to e-Invoice?

The use of e-Invoices has brought significant advantages for many businesses aiming to speed up their accounting processes in the business world. Especially saving time and costs contributes to enhancing operational efficiency. However, there are some important points to consider during the transition to the e-Invoice system. As Üstad, we addressed the e-Invoice transition process in this week's blog post.

What is e-Invoice?

An e-Invoice is an electronic document with the same legal characteristics as a paper invoice, where communication between the buyer and seller is carried out through a centralized platform with standards and formats determined by the Revenue Administration. The communication of e-Invoices, which are issued, sent, and stored electronically, takes place through the GİB system between the buyer and seller.

How to Transition to E-Invoice?

Businesses wishing to transition to the e-Invoice application must first obtain a financial seal certificate. This certificate verifies the corporate identity of the business. The steps to follow to transition to the e-Invoice system after obtaining the financial seal are as follows: 

• You can create your system registration through the e-Invoice portal affiliated with the Revenue Administration.

• You can use the e-Invoice system through GİB, via private integrators, or through your own private information processing systems.

• After making your choice, you can activate the system by testing it.

If you want to manage all your accounting processes from a single platform, you can connect your e-Invoice integrator, such as Paraşüt, Uyumsoft, e-Logo, or İşnet, to Üstad by entering your username and password. After integration, all invoices are automatically transferred and categorized into the system. All your documents are encrypted and stored in compliance with KVKK.

All businesses meeting the necessary criteria can voluntarily switch to the e-Invoice. However, for businesses exceeding the defined thresholds, switching to the e-Invoice is mandatory. The conditions and thresholds requiring compulsory transition to e-Invoice are as follows:

e-Invoice Sending and Receiving Process

The steps to follow in the e-Invoice sending and receiving process are as follows:

• The e-Invoice is prepared via the GİB portal, special accounting software, or private integrators. 

• The prepared e-Invoice is sent to the GİB system for verification.

• Once the GİB system verifies this invoice, it is forwarded to the buyer who is a taxpayer of the e-Invoice. 

• The sent or received invoices are recorded in the accounting software used by the businesses or in the GİB portal and are kept on record to be used when necessary. 

You too can manage both the ease of managing accounting processes and the tracking of documents, including the e-Invoice, from a single platform with Üstad. You can get in touch with your financial advisor at any time and keep your accounting and tax processes under control.
