Documents and Registrations Required for Trading in Türkiye

The Core: Tax Registration

Trading requires tax registration. The sequence is short: the start-of-business filing, the tax certificate, registry records and chamber membership. Formation as a whole is covered in the business guide.

A sole proprietorship suffices for most starts; a company comes forward for imports, corporate supply and partnerships (decision guide).

The activity code: the quiet decider

In trade the NACE code sets which products you may sell and which extra registrations apply. Wholesale and retail, food and textiles are separate codes. Choose it thinking of the products you may add within two years.

The Product Layer: Depending on What You Sell

Food trading requires a business registration certificate and storage and hygiene conditions; cosmetics and cleaning products carry notification duties; electronics and toys bring conformity marks and import records; second-hand vehicles and phones require authorisation certificates.

The rule of this layer: no document list can be drawn before the product is chosen. Fields and their document burdens are compared in the twelve fields guide.

The Channel Layer: Depending on Where You Sell

A trader with a physical store or warehouse obtains an operating licence (licensing guide). Selling online brings distance-selling duties: pre-contract information, the right of withdrawal, a returns process and visible business details.

Marketplaces demand their own document set: tax certificate, signature circular, bank details, and in some categories brand and authorised-seller documents. Channels are compared in the channels guide.

Invoicing and Records

Trade’s daily document is the invoice. E-invoice and e-archive obligations arrive with turnover thresholds and sector; those below may join voluntarily, and corporate customers usually expect it.

Two things join it: stock records — what came in, what went out, what remains — and receivables tracking. Most losses in trade come from unmeasured stock and unchased receivables (margin guide).

The Foreign Trade Layer

Entering import and export grows the layer: customs registrations tied to the tax number, exporters’ association membership, conformity and origin documents by product group, and transport and insurance paperwork.

Working with a customs broker is close to standard here; first steps are in the foreign trade guide.

The Contract: the Most Skipped Document

It appears on no official list, yet the most protective document in trade is a written agreement: product description, quantity, price, place and time of delivery, payment terms, defect and return conditions, and what happens on delay.

Even a one-page order form is far stronger than a verbal agreement. Negotiation and contract language sit in the negotiation guide. In credit sales, every clause left unwritten becomes an argument on collection day.

Field Note

A trader won a first corporate order and shipped the goods; at invoicing he discovered he had neither e-invoice registration nor an integrator. The goods were with the customer, the invoice could not be issued, and the payment schedule slipped. The documents looked “complete”; what was missing was the document of daily operations.

Quick Summary

The order: tax registration → activity code → product layer → channel layer → invoicing and stock records. A physical warehouse or store adds a premises licence. Foreign trade brings its own layer. Set up e-invoicing before the first invoice and tie every sale to a written agreement.
