What is E-Transformation?

What is E-Invoice?

E-invoices are the electronic version of paper invoices issued by businesses for their commercial activities. Prepared in accordance with the standards set by the Revenue Administration, e-invoices have the same legal validity as paper invoices. This system allows businesses to both fulfill their legal obligations and execute their business processes more quickly and securely.

Using e-invoicing offers businesses many advantages. First and foremost, it eliminates costs such as paper, printing, and archiving. Electronically stored invoices are easy to find and can be shared quickly when necessary. Furthermore, the e-invoicing system minimizes the margin for error. Errors in date, amount, or tax calculations, common with manual invoicing, are largely prevented with the e-invoicing system.

E-invoicing is also an environmentally friendly solution. Reducing paper consumption not only reduces business costs but also contributes to environmental protection. In today's world where digitalization is rapidly spreading, businesses that don't use e-invoicing are losing time and falling behind their competitors. You too can switch to e-invoicing to prepare your business for the future and securely manage your official documents. For more details, please visit our "What is E-Invoicing" page.

What is E-Signature?

An e-signature is the electronic equivalent of a wet signature. According to Electronic Signature Law No. 5070, an e-signature is an electronic certificate that verifies the source of data and guarantees the integrity of the signed data. It is used to verify personal identity and has the same legal validity as a wet signature.

One of the greatest advantages of e-signatures is the ability to securely sign official documents digitally. E-signatures can be used in e-government applications, correspondence with official institutions, commercial contracts, tenders, and banking transactions. This allows individuals and institutions to sign legally valid signatures without requiring any physical documentation.

E-signatures also enhance document security. It's impossible to change the signed document later. This strengthens trust in both business and public transactions. E-signatures can also be timestamped, allowing for precise identification of the date the signed document was approved.

During the digital transformation process, e-signatures enable businesses and individuals to manage their business processes with fast, secure, and modern solutions. You can find more information about securely signing your documents electronically with e-signatures on our "What is an E-Signature" page.

What is a Financial Seal?

A fiscal seal is an electronic certificate that legal entities, namely companies, are required to use in their e-document applications. Mandatory for the signing and verification of e-invoices, e-ledgers, and similar official documents, the fiscal seal provides authorization to sign on behalf of the company.

A fiscal seal should not be confused with an e-signature. While an e-signature is valid for individuals, a fiscal seal is used for the legal identity of companies. Therefore, a company must obtain a fiscal seal to transition to an e-invoicing system. A fiscal seal device is typically issued in the form of a smart card or USB token. This device is used to sign e-documents and securely transmit them to the Revenue Administration system.

The fiscal seal verifies the source of issued e-invoices, guarantees document security, and prevents potential fraud. Furthermore, the fiscal seal provides legal validity for all financial transactions conducted electronically by companies.

Today, a financial seal is a necessity for every company participating in the e-transformation process. You can apply for a financial seal as the first step in your business's digitalization process. For more information, please visit our "What is a Financial Seal" page.

What is a KEP Address?

Registered Electronic Mail (KEP) is the system that ensures the legal validity of emails sent electronically. A KEP address ensures the security of official correspondence, the content of messages cannot be altered, and the time of sending is recorded.

A KEP address is particularly important for companies. Official correspondence such as commercial agreements, contract notices, warnings, and notifications sent through KEP serve as evidence in court. This eliminates any doubt about the validity of emails sent in disputes between parties.

The KEP system can be thought of as an electronic adaptation of the traditional mail system. However, the key difference is that security and legal validity are preserved in the digital environment. When an email sent via KEP is received by the recipient's system, a legally valid delivery report is presented to both the sender and recipient.

Obtaining a KEP address is now essential for businesses to conduct official correspondence securely, quickly, and cost-effectively. You can apply for a KEP to secure your company's official communications. You can find more information on our KEP Address page.

UBL Codes

UBL, or Universal Business Language, is an international business language that enables e-invoices to be prepared in a standard format and processed seamlessly across systems. The e-invoicing system in Türkiye uses the UBL-TR format, as defined by the Revenue Administration.

Thanks to UBL codes, invoices contain standardized information such as sender, recipient, product, quantity, and tax rate. This standard not only ensures compatibility across software but also simplifies invoice control and auditing processes. For example, UBL codes enable the accurate processing of fields such as "VAT exemption code" or "withholding code" in an e-invoice.

UBL codes prevent businesses from making errors in their e-invoicing processes and prevent data discrepancies that may occur on invoices. This internationally accepted system also simplifies companies' international commercial transactions.

In the increasingly digital world of business, every business issuing e-invoices needs to know and correctly apply UBL codes. You can also review our UBL Codes page to learn more about UBL codes and their uses.
