Comparison of E-Invoicing Processes: Basic E-Invoice or Commercial E-Invoice?

 

One of the first questions businesses encounter when they start issuing e-Invoices is whether they should choose a Basic e-Invoice or a Commercial e-Invoice. Although this may seem like a minor decision, the selected scenario directly affects important processes such as invoice approval, the recipient's right to object, and cancellation procedures. In this guide, we explain when each e-Invoice scenario should be used, outline the key differences between Basic and Commercial e-Invoices, and discuss the approval, rejection, and cancellation processes in detail.

 

What Are e-Invoice and e-Transformation?

 

An e-Invoice is an electronic invoice created, transmitted, and stored digitally in accordance with the standards established by the Turkish Revenue Administration (GİB). Prepared in the UBL-TR format, e-Invoices have the same legal validity as paper invoices and are recognized as official commercial documents.

e-Transformation is a broader digitalization process that covers not only e-Invoices but also other electronic documents such as e-Delivery Notes (e-Waybills) and e-Professional Receipts. Businesses can join this system either through the GİB Portal or by using an authorized private integration service provider. Beyond being a legal requirement for many businesses, e-Transformation accelerates accounting workflows, minimizes manual errors, and eliminates the need for physical document storage.

Unlike paper invoices, e-Invoices are delivered electronically to the recipient through the GİB infrastructure within a very short time. However, the way an invoice is processed depends on the selected invoice scenario. The two most commonly used scenarios are Basic e-Invoice and Commercial e-Invoice.

 

What Are the Types of e-Invoice Scenarios?

 

The e-Invoice system offers different scenarios depending on the nature of the transaction. Each scenario defines the invoice's purpose, recipient, and the approval mechanism involved. The most frequently used e-Invoice scenarios are listed below.

 

Scenario	Primary Use
Basic e-Invoice	Service sales, subscriptions, and standard invoicing for individual or corporate customers
Commercial e-Invoice	Business-to-business (B2B) transactions requiring mutual confirmation
Export Invoice	Sales of goods and services to customers outside Türkiye
Tax-Free (Passenger Accompanied Goods) Invoice	Sales to foreign visitors eligible for VAT refunds
Public Institution Invoice	Invoices issued to government institutions and public organizations

 

What Is a Basic e-Invoice?

 

A Basic e-Invoice is an e-Invoice scenario in which the invoice is transmitted to the recipient through the Turkish Revenue Administration (GİB) system and is automatically deemed accepted once it has been successfully delivered. Under this scenario, the recipient cannot approve or reject the invoice through the system. The invoice is processed directly for accounting purposes, while the recipient may only raise an objection through the applicable legal procedures if technical errors, duplicate records, or similar issues are identified.

 

Key Features of a Basic e-Invoice

 

• The invoice is automatically considered accepted as soon as it reaches the recipient; no additional approval is required.
• The recipient cannot reject the invoice through the e-Invoice system.
• If the invoice contains technical errors, duplicate entries, or other significant inaccuracies, objections may be submitted through the official channels designated by GİB.
• Because of its streamlined workflow, this scenario is widely preferred for high-volume and recurring invoicing.
• Invoice cancellations are carried out through the GİB e-Invoice Cancellation/Objection Portal, Registered Electronic Mail (KEP), or a notary public. A direct system-based rejection option is not available.

 

When Should a Basic e-Invoice Be Used?

 

The Basic e-Invoice scenario is best suited for routine transactions where disputes are unlikely and rapid invoice processing is important. Common examples include:

 

1. Utility and subscription services such as electricity, water, natural gas, and internet bills.
2. Services provided to end consumers or individual customers.
3. Membership fees, subscription charges, and other predetermined recurring payments.
4. Sales made to public institutions where an invoice approval process is generally unnecessary.

 

What Is a Commercial e-Invoice?

 

A Commercial e-Invoice is an e-Invoice scenario that allows the recipient to review the invoice and either approve or reject it through the GİB system. Once the invoice has been delivered, it remains in a "Pending Response" status for a specified period. During this time, the recipient may either accept the invoice or reject it by sending an Application Response for Rejection through the system.

 

      Key Features of a Commercial e-Invoice

• The recipient has the option to approve or reject the invoice electronically.
• If no response is provided within eight days of receipt, the invoice is automatically regarded as accepted by the system.
• The sender can monitor whether the invoice has been approved or rejected directly from their e-Invoice interface.
• This scenario offers greater control for transactions involving product returns, price                                                                                                                 adjustments, or commercial reconciliation
• Invoice rejection is performed directly within the system, eliminating the need for a separate cancellation portal.

 

When Should a Commercial e-Invoice Be Used?

 

A Commercial e-Invoice is the preferred option for transactions that require confirmation between the parties or where the possibility of objections is relatively high. Typical use cases include:

1. Business-to-business (B2B) sales and purchases of goods.
2. Manufacturing and raw material procurement processes requiring quantity or price verification.
3. Commercial relationships where full or partial product returns may occur.
4. Transactions involving mutual agreement on pricing, payment terms, or delivery conditions.

 

Basic e-Invoice vs. Commercial e-Invoice: A Comparison

 

The primary differences between the two e-Invoice scenarios lie in the recipient's ability to respond to the invoice and the procedures for cancellation. The table below provides a side-by-side comparison of their main characteristics.

Feature	Basic e-Invoice	Commercial e-Invoice
Right to reject through the system	Not available	Available (within 8 days)
Approval process	Automatically accepted upon delivery	Subject to recipient approval or rejection
Cancellation method	GİB Cancellation/Objection Portal, Registered Electronic Mail (KEP), or notary public	Rejection through the Application Response within the system
Typical use cases	Service invoices, subscriptions, membership fees, and routine transactions	B2B sales, manufacturing, procurement, and supply chain operations

As illustrated above, the most significant distinction between these two scenarios is the recipient's ability to respond to the invoice. The Basic e-Invoice scenario prioritizes speed and simplicity, whereas the Commercial e-Invoice scenario provides an additional layer of control by allowing both parties to confirm or reject the transaction. Agreeing on the appropriate invoice scenario before issuing an invoice can help prevent disputes and simplify cancellation or objection procedures.

 

Who Can Issue an e-Invoice?

 

To issue an e-Invoice, a business must first be registered as an e-Invoice taxpayer with the Turkish Revenue Administration (GİB). Any tax-registered business may join the e-Invoice system voluntarily or as required by law and issue invoices through the GİB Portal, an authorized private integrator, or a direct integration method.

Businesses that exceed the turnover thresholds or meet the sector-specific criteria established by the Turkish Revenue Administration are legally required to adopt e-Document applications. In such cases, paper invoices must be replaced with either e-Invoices or e-Archive Invoices, depending on the recipient's status.

The issuer is responsible for selecting either the Basic or Commercial e-Invoice scenario. However, the chosen scenario can only be applied if the recipient is also registered in the e-Invoice system. If the customer is not an e-Invoice user, an e-Archive Invoice must be issued instead.

 

Key Differences Between Basic and Commercial e-Invoices

 

The following table summarizes the main distinctions between the two invoice scenarios.

Basic e-Invoice	Commercial e-Invoice
The invoice is automatically deemed accepted once it reaches the recipient. No additional approval is required.	The recipient can review the invoice and either approve or reject it through the system.
Rejection cannot be performed electronically. Cancellation and objection procedures must follow the official methods defined by GİB.	Approval or rejection is transmitted directly to the sender through the e-Invoice system.
Errors or inaccuracies must be resolved through formal cancellation or objection procedures.	The built-in rejection mechanism enables faster handling of invoice disputes and commercial disagreements.

 

Which e-Invoice Scenario Should You Choose?

 

The most appropriate e-Invoice scenario depends on the nature of your transaction.

For recurring services, subscription-based billing, and transactions where disputes are unlikely, the Basic e-Invoice scenario is generally sufficient due to its fast and straightforward processing.

On the other hand, Commercial e-Invoices are better suited for business-to-business transactions, product sales, procurement activities, and situations involving potential returns, price adjustments, or contractual confirmation. Because recipients have the option to approve or reject invoices, this scenario offers greater flexibility and transparency throughout the invoicing process.

Whenever possible, both parties should agree on the invoice scenario before the transaction takes place. If no prior agreement exists, the Commercial e-Invoice scenario is often considered the more practical choice for commercial transactions, as it provides a structured approval and rejection mechanism that helps businesses manage disputes more efficiently.
