e-Accounting Vouchers: What They Are, Why They Matter, and How to Create Them

What is an e-Accounting Voucher, and How is it Created? (Comprehensive 2026 Guide)

Digital transformation is reshaping how companies manage their financial processes.

In parallel with e-Ledger (e-Defter), accounting vouchers, also known as journal vouchers, are now created and signed electronically. This shift not only reduces resource consumption but also eliminates dependency on printers, office supplies, and physical archives.

According to the Communiqué No. 1 on Electronic Ledgers, specifically Section 4.4 titled “Retention and Submission of e-Ledger Files, Certificate Files, and Accounting Vouchers,” taxpayers included in the e-Ledger system are required to retain accounting vouchers alongside their e-Ledger and certificate files, either in physical or electronic form.

So, what exactly is an e-accounting voucher? Why has it become essential for businesses? And what should you consider when creating one?

In this guide, we walk you through everything, from definitions and legal requirements to benefits and SAP integration, step by step.

If you are looking to digitize your financial processes, improve operational efficiency, and minimize compliance risks, this guide is for you.

Introduction to e-Accounting Vouchers: The Foundation of Digital Finance

With digital transformation, finance and accounting processes are no longer confined to paper-based workflows.

Companies increasingly rely on electronic systems to improve speed, accuracy, and auditability. In this context, e-accounting vouchers have become a cornerstone of the digital accounting ecosystem.

They enable organizations to maintain financial records securely and systematically in a digital environment.

This is an essential step for both compliance and operational efficiency. For companies using integrated ERP systems like SAP, automating e-accounting voucher processes delivers significant time and cost savings.

What Is an e-Accounting Voucher?

An e-accounting voucher is the digital equivalent of a traditional paper voucher.

Just like its physical counterpart, it serves as the primary document for journal entries, but it is created, stored, and presented electronically.

By using e-accounting vouchers, finance teams can record transactions quickly and accurately without relying on manual data entry.

Types of Accounting Vouchers

Accounting vouchers are categorized based on the type of financial transaction. The same classification applies in digital environments. There are three main types:

Journal Voucher (Adjustment Voucher)

Used primarily to settle internal accounts or reflect debit-credit balances.

Journal vouchers are ideal for recording transactions involving multiple accounts simultaneously. For example, offsetting departmental expenses or closing advance payments against final accounts.

When created electronically, all entries are securely recorded and fully compliant with regulations.

Collection Voucher

Used to record incoming payments and document collection processes.

For instance, customer payments are recorded through collection vouchers. In electronic form, payment dates and amounts can be tracked clearly, which accelerates reporting and auditing processes.

Payment Voucher

Used for outgoing payments and disbursement transactions.

Employee salaries, supplier payments, and other cash outflows are recorded using payment vouchers. When processed electronically, these records are stored within legal timeframes and protected through qualified electronic signatures or financial seals.

Are e-Accounting Vouchers Legally Mandatory?

The use of electronic accounting vouchers is a legal requirement. Especially for e-Ledger taxpayers, implementing this practice is mandatory for compliance with financial legislation and ease of auditing.

Legal Basis: Communiqué No. 1 on Electronic Ledgers

The regulation clearly states that taxpayers within the e-Ledger system must retain accounting vouchers along with their e-Ledger and certificate files and present them when required.

This obligation applies to both physical and digital records. It covers the full lifecycle, including creation, signing, and archiving of vouchers in electronic format.

Recording Deadline and the 45-Day Rule (Tax Procedure Law Article 219)

According to Article 219 of the Tax Procedure Law (VUK), all accounting records must be posted to the journal within 45 days.

e-Accounting vouchers ensure this requirement is met efficiently and securely in a digital environment.

Benefits of Switching to e-Accounting Vouchers

Adopting e-accounting vouchers goes beyond compliance. It brings significant operational and financial advantages.

Operational Efficiency and Speed

Electronic vouchers reduce reliance on manual data entry and accelerate approval workflows.

Instead of processing hundreds of entries manually, finance teams can generate vouchers automatically. This minimizes human error and significantly speeds up accounting operations.

Automated validation and 45-day rule tracking also eliminate the need for manual follow-ups.

Cost Savings (Paper, Printing, Archiving)

Eliminating paper-based processes removes printing and physical storage costs.

For large organizations, these expenses can add up significantly. Digital vouchers reduce them to near zero while freeing up physical storage space.

Secure and Easy Archiving

e-Vouchers are stored centrally and securely in digital environments.

This eliminates the risk of physical loss and makes retrieval fast and efficient, especially during audits.

Remote Accessibility and Audit Readiness

Authorized users and auditors can access vouchers from anywhere with an internet connection.

This improves transparency and speeds up audit processes by removing the need to handle physical documents.

Data Integrity and Security (via Qualified e-Signature or Financial Seal)

e-Accounting vouchers are signed using qualified electronic certificates or financial seals, ensuring data integrity.

This prevents unauthorized modifications and guarantees legal validity while enabling secure tracking and reporting.

Step-by-Step: How to Create an E-Accounting Voucher?

The process of creating an e-accounting voucher may seem technical and complex at first glance.

However, when the right systems and a standardized workflow are adopted, this process can be managed both quickly and accurately. Particularly through solutions that work integrated with ERP systems (e.g., SAP), manual processes are minimized, and legal requirements are met automatically.

The most important points to consider when creating an e-accounting voucher are: data accuracy, preparing the voucher in the appropriate format, signing it electronically, and storing it within legal timeframes.

Below, you can find the fundamental steps of this process in a simple and actionable way:

Gathering Necessary Information

To create the voucher, account details, amounts, transaction dates, and related documents must be prepared completely. Missing or incorrect data can risk both the accuracy of accounting records and legal compliance.

Creating the Voucher Electronically (Manual and Automated Methods)

E-accounting vouchers can be created either directly through the ERP system or automatically via specialized software. While user control is high in manual methods, speed and standardization take precedence in automated methods.

Signing with QES or Financial Seal

For the voucher to be legally valid, it must be signed with a Qualified Electronic Signature (QES) or a Financial Seal. This step guarantees the integrity and immutability of the voucher.

Storage Within Legal Periods

Created vouchers must be stored electronically alongside e-ledger and certificate files and must be presented when necessary. Compliance with legal retention periods is of critical importance during audit processes.
