Trendyol e-Faturam Integration: Automated Invoicing and GİB Compliance

Issuing an e-Fatura or e-Arşiv invoice for every sale on Trendyol is a legal requirement — and it directly affects your Trendyol Seller Score. In this guide we explain step by step where “trendyol faturam” actually is, how to issue the e-invoice for your sales and how to automate the entire process.

First, let's be clear: which one is “Trendyol faturam”?

When sellers search for “trendyol faturam”, they often mean two different documents. It is critical not to mix them up:

Document	Who issues it?	Where to find it / what to do?
The invoice Trendyol issues to you (commission, service, advertising fees)	Trendyol	Downloaded as PDF from Trendyol Seller Panel → Finance → Current Account / Payouts. You record these invoices as expenses in your accounting.
The sales invoice you issue to the customer (e-Fatura / e-Arşiv)	You (the seller)	Trendyol does not issue it. It is issued via the GİB Portal or an integrator and uploaded to the order. This is the main subject of this guide.

Is e-invoicing mandatory on Trendyol? Impact on your score

Yes. Every taxpayer selling on Trendyol must issue a legal sales document (e-Fatura or e-Arşiv) for every order. Moreover, this is not just a legal obligation; it is a component of the Trendyol Seller Score:

• The invoice is expected to be uploaded to the order within 24 hours of shipping confirmation.
• Delays of more than 48 hours lead to a low-performance warning.
• Persistently late invoices can lead to loss of the Buy Box and listing restrictions.

In other words, invoicing is not just accounting — it is directly a matter of sales and visibility.

Should you issue an e-Fatura or an e-Arşiv invoice?

Both are mandatory tools; the buyer determines which one is issued:

	e-Fatura	e-Arşiv invoice
For whom?	Corporate buyer purchasing with a VKN and registered for e-Fatura	End consumer with a TCKN or a buyer not registered for e-Fatura
How is it delivered?	Via the GİB system to the buyer's mailbox	Email/SMS to the buyer; the record is reported to GİB
Share on Trendyol	Small minority	The vast majority of orders (~90%+)

Because Zunapro selects the right type automatically from the buyer's VKN/TCKN, the “I issued the wrong document” error disappears.

How do you issue a Trendyol e-invoice? 2 ways

Way 1 — GİB Portal (manual, free)

GİB's e-Belge portal is free. For each order you enter the buyer details, product, amount and VAT one by one, create the invoice, download the PDF and upload it to the Trendyol order. It works for very small sellers with fewer than 30–50 invoices a month; but as order volume grows, the cost in time and errors multiplies.

Way 2 — Automation (integrator + Zunapro)

A GİB private integrator (Logo, Mikro, Uyumsoft, Paraşüt, İzibiz, etc.) legally generates the invoice; Zunapro bridges Trendyol and this integrator: as soon as an order comes in, the invoice is created automatically, the right type is selected, it is transmitted to GİB and uploaded to the Trendyol order. Manual entry, delays and damage to your score are eliminated.

Comparison	GİB Portal (manual)	Zunapro automation
Time per invoice	Minutes (manual entry)	Automatic (no manual entry)
Correct type (e-Fatura/e-Arşiv)	Manual decision	Automatic from VKN/TCKN
Upload to Trendyol	Manual	Automatic
Risk to score / Buy Box	High (delays)	Low
Multiple stores / multiple marketplaces	Separate work for each	From a single panel

VAT rates and shipping fees

In Turkey, VAT is category-based: 20% standard, 10% reduced (some food/textile/health items), 1% low (basic food, books, newspapers). Points to watch on the invoice:

• Matching the product to the correct VAT rate (a wrong rate means a correction later).
• Reflecting campaigns/discounts in VAT proportionally.
• The shipping fee is usually entered as a separate line with 20% VAT.

Zunapro maps the Trendyol category tree to VAT rates; when an order arrives, product → category → rate is assigned automatically.

Returns and invoice cancellation

Because return rates on Trendyol are high, the cancellation/return process is critical:

• e-Arşiv: can be cancelled within 8 days; if that period has passed, a return invoice or an expense voucher (gider pusulası) is issued.
• e-Fatura: unilateral cancellation within 8 days; after that, the buyer's approval (rejection/response invoice) is required.

When a return approval arrives from Trendyol, Zunapro checks the date window and automatically triggers the right process (cancellation or return invoice).

Choosing an integrator: which one suits whom?

Integrator	Best-fit profile
Paraşüt / İzibiz	SMEs and boutique sellers; affordable monthly cost, works well with accountants
Logo / Mikro	High volume, corporate structure with ERP, need for e-Defter (e-ledger)
Uyumsoft	Mid-to-large sellers wanting customization flexibility
Foriba / Veriban	High invoice volume, corporate SLA

How does Trendyol e-invoice automation with Zunapro work?

1. You connect your Trendyol Seller account (store ID + API credentials) to Zunapro.
2. You define your e-invoice integrator (or we recommend one).
3. As soon as an order comes in, Zunapro generates the invoice, selects the right type and calculates VAT.
4. The invoice is transmitted to GİB and uploaded automatically to the Trendyol order.
5. If a return comes in, the cancellation/return process runs automatically; everything is reported in a single panel.

The same setup works for Hepsiburada, N11, Amazon and your other marketplaces — multiple stores and multiple marketplaces are managed from one place.
