Step-by-step, in-depth guides to Turkish e-invoicing, e-archive invoices, marketplaces and e-commerce tax.
Marketplace profit is what remains after you deduct commission, shipping, service fees, product cost and return costs from the net-of-VAT sales amount. VAT and the e-commerce withholding tax are not profit items: one represents your tax liability, the other a tax paid in advance.
Payout reconciliation means matching the amount the marketplace pays you, line by line, against your own order, invoice, return and deduction records and tying every difference to a cause. Do it separately for each marketplace, at least once a month.
Automatic e-invoicing is a workflow that transfers the buyer, address, product, VAT, discount and shipping details from a marketplace order directly into the invoice, issues an e-invoice or an e-archive invoice depending on the seller's and buyer's status, and sends the invoice to the marketplace.
If you sell on more than one marketplace, keep your stock in one central place, map every variant to your channels by barcode and SKU, deduct stock on order and add it back on cancellation and return; prevent overselling with safety stock, threshold alerts and regular counts.
In 2026, the penalty for not issuing or not receiving an invoice (VUK 353/1) is 10% of the document amount for each document, and it cannot fall below minimum amounts ranging from 17,000 TL to 170,000 TL depending on the detection order; the annual cap is 17,000,000 TL.
Since January 1, 2025, marketplaces in Türkiye have withheld 1% tax from seller payouts, calculated on the VAT-exclusive sales price. Sellers offset this amount in their provisional and annual tax returns.
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.
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.
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.
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.
