For foreign companies and subsidiaries operating in Türkiye, these rules affect not only invoicing but also warehouses, dispatch, and ERP integration. This guide explains the current thresholds, sector-based obligations, the e-Arşiv rule, the operational impact, and how to prepare.

In international trade, the proforma invoice is often the first formal document a buyer sees.

This guide explains what a proforma invoice is, what it should contain, how it differs from a commercial invoice, and how to avoid the most common errors.

This guide explains what a marketplace integration covers, the main integration approaches, the most common inventory sync problems, and how to build an integration that prevents overselling.
