Up-to-date, regulation-based guides to Turkish e-invoicing (e-Fatura, e-Arşiv, e-İrsaliye), marketplaces (Trendyol, Hepsiburada, N11, Amazon, Temu) and e-commerce accounting.
From January 1, 2026, taxpayers other than those on the simplified method and the operating account basis issue all their invoices as e-archive invoices regardless of amount. Simplified-method and operating-account taxpayers have a 3,000 TL exemption (taxes included) in 2026; it is removed in 2027.
e-Archive Invoice (e-Arşiv)Q&A
In addition to standard invoice details, an e-archive invoice for online sales includes the website address, payment method, payment date, the carrier's name/trade name and tax ID (VKN) or Turkish ID number (TCKN), and a return section; the invoice is delivered to the buyer electronically.
Exemption code 351 means "VAT - Other Non-Exempt" and is not a real exemption. It is used with the SATIS type when a transaction is not exempt but still needs a zero-VAT invoice. For genuine exemptions such as exports, you choose a 3xx/2xx code and the ISTISNA type instead.
On Trendyol, a title can be at most 100 characters, on n11 15–65, and on Amazon.com.tr 200 in most categories; Hepsiburada does not publish an official limit. In this guide, you will find the product naming rules of four marketplaces, good and bad title examples, and a method for multichannel listing.
In Türkiye, consumers can return a product bought online within 14 days of delivery without giving a reason. From 2026, the cost of a withdrawal return sent with the seller's designated carrier cannot be charged to the consumer.
In marketplace sales, the seller issues the invoice and sends it to the platform within 7 days. This guide covers choosing the document by customer type, sending the invoice on each marketplace, and the rules for coupons, shipping and returns.
Since August 1, 2026, the previous price shown in a discount ad in Türkiye must be the lowest price of the last 10 days before the discount starts (the previous rule was 30 days); the discount dates must also be stated.
A Trendyol product title can be up to 100 characters and follows the order Brand + Product type + Key feature + Variant. This guide explains how to fill in each part, where color and size belong in the title, and shows examples by category.
Debit the commission invoice's amount excluding VAT to 760 and its 20% VAT to 191, and credit the total to 320 Suppliers. When the marketplace payout arrives, offset the 320 payable against the 120 Customers receivable.
Special tax base codes (801–812) mark transactions where VAT (KDV) is calculated on a special tax base set by law instead of the full sale price, such as gold and silver jewelry, tobacco products and used vehicles. They are valid only with the OZELMATRAH, IADE and SGK invoice types.
Shipping & LogisticsGlossary
Desi is the weight equivalent calculated from a shipping package's volume. For domestic shipments in Türkiye, it is found with the formula (width x length x height, cm) / 3000, and the shipping fee is based on whichever is higher: desi or kilograms.
Trendyol requires 1200x1800 pixels (2:3), 96 dpi and a maximum of 8 images; Amazon's main image must be on a plain white background, with the product filling at least 80% of the frame. We have also gathered the recommended approach for Hepsiburada, n11 and Temu in a table.
