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.
Marketplace OperationsGlossary
The Buy Box is the featured seller that the "Add to Cart" button on a product page is tied to when several sellers offer the same product. Price, shipping time, seller rating and stock generally matter; marketplaces do not disclose the formula.
e-Invoice (e-Fatura) taxpayers with gross sales revenue of 10,000,000 TL or more switch to the e-dispatch note (e-İrsaliye) from July 1 of the following year; certain sectors are covered regardless of revenue. An e-dispatch note is issued before the goods are shipped.
In Türkiye, an invoice must be issued no later than 7 days from the date the goods are delivered or the service is performed (Tax Procedure Law (VUK) 231/5). An invoice not issued within this period is deemed never to have been issued and may be subject to a special irregularity penalty.
On Trendyol, a product title can be at most 100 characters. Spaces count too. Put the brand and product type first, and keep the title under the limit and easy to read.
e-Archive Invoice (e-Arşiv)Q&A
Because a consumer cannot issue a return invoice, the seller issues an expense voucher for the returned goods. No withholding tax is applied on this document, and a VAT adjustment can be made. A signed return section on the e-archive invoice replaces the expense voucher.
In 2026, under Article 232 of the Tax Procedure Law (VUK), the invoice threshold for sales to end consumers in Türkiye is 12,000 TL (9,900 TL in 2025); for precious metals it is 36,000 TL. For sales to merchants, self-employed professionals, farmers and exempt tradespeople, an invoice is issued regardless of the amount.
All full (3xx) and partial (2xx) VAT exemption codes under UBL-TR Code Lists 1.43, the invoice types each code is valid for, and the September 14, 2026 changes on one page.
In e-invoices, C62 is used for pieces. NIU means "number of international units" and does not mean pieces. Kilogram is written as KGM, liter as LTR, meter as MTR, set as SET, pair as PR, box as BX and pack as PA.
In 2026, the e-invoice (e-Fatura) transition thresholds remain unchanged: 3,000,000 TL in general, and 500,000 TL for online sales, real estate and motor vehicle businesses. A taxpayer who reaches the threshold uses e-invoices from July 1 of the following year.
If you make products by hand at home and sell them only online, you can use the Income Tax Law (GVK) Article 9/1-10 tradesman exemption in 2026 for revenue up to 1,900,000 TL; if you also sell through offline channels, Article 9/1-6 and its 396,360 TL limit apply.
Code 555 means "Sales Not Subject to VAT Rate Control." Since April 1, 2026, integrators in Türkiye check the VAT rate against your activity (NACE) code, so you select 555 for recharges or fixed asset sales made at a rate that doesn't match that code. VAT cannot be 0.
e-Archive Invoice (e-Arşiv)Q&A
The cancellation period for an e-archive invoice is 8 days from the date the invoice is delivered to the buyer. Once this period ends, the Turkish Revenue Administration system no longer allows cancellation; a consumer return is documented with an expense voucher or the return section on the invoice.
