Almost everyone who issues an e-Invoice faces the same question on the same screen: should the scenario be a “basic invoice” or a “commercial invoice”? Both are the same legal invoice; there is no difference between them in terms of amount, VAT, accounting entry, or tax consequence. The difference comes down to a single point: whether the recipient can reject the invoice through the system.
The basic invoice scenario
With a basic invoice, the recipient cannot reject the incoming invoice through the e-Invoice system. In other words, the counterparty cannot send a systemic rejection via an “application response”; the invoice lands in their inbox the moment it is sent and is deemed accepted. The right to object is not eliminated, but that objection is made outside the system: through a notary, registered return-receipt mail, telegram, or KEP (Registered Electronic Mail).
This scenario is practical for transactions where the recipient has no need to turn the invoice back and the flow is expected to proceed quickly and smoothly. The process is lean; there is no extra approval/rejection step.
The commercial invoice scenario
With a commercial invoice, the recipient can accept or reject the invoice through the e-Invoice system. If there is an error, an omission, or something contrary to the agreement, the recipient formally objects by sending a “rejection application response” through the system within the legal objection period. The objection is thus recorded, and both parties see the same systemic trail.
This scenario is preferred in relationships where it matters that the recipient can review and turn back the invoice — where the likelihood of a return, correction, or reconciliation is high.
The difference between the two scenarios, in short
- Basic invoice: NO systemic rejection. Any objection is made externally (notary, KEP, registered return-receipt mail, telegram).
- Commercial invoice: Systemic rejection is POSSIBLE. The recipient can object to the invoice systemically via an application response.
- Amount, VAT, accounting, and tax outcome: the SAME in both scenarios. The scenario determines the objection method, not the invoice's validity.
- Practical rule: commercial is more suitable for transactions that may need an objection/rejection flow; basic is more suitable for those that will not.
Which one to choose, and when?
The decision really comes down to one question: “Would it help me for the recipient to be able to reject this invoice through the system, or would it just create unnecessary friction?” In practice, the typical split looks like this:
- Commercial relationships with frequent returns, partial deliveries, or order corrections (e.g. dealer–supplier, wholesale) → commercial invoice; the systemic rejection flow makes things easier.
- Standard, low-objection-probability, one-off, or service-fee transactions → basic invoice; it simplifies the process.
- The counterparty wants to use systemic rejection in their own accounting approval flow → commercial invoice meets the expectation.
- When unsure → if an objection might arise, choosing commercial keeps you on the safer side.
The right to object exists in both scenarios
Let us correct an important misconception: choosing a basic invoice does not eliminate the recipient's right to object. Under the Turkish Commercial Code, the right to object to an invoice is reserved; with a basic invoice this objection is made through channels outside the system, and with a commercial invoice it can additionally be made through the system. The difference is not whether the right exists, but through which channel the objection is carried out.
