Is It Mandatory to Establish a Company to Open a Store on Trendyol? (2026 Guide)

Selling on digital marketplaces offers a great income opportunity, especially on large platforms like Trendyol, Hepsiburada, and n11, but it raises a critical question:

Can I open a Trendyol store without establishing a company?

As of 2026, to open a store on Trendyol, it is mandatory to be a taxpayer, meaning you must have a company (Sole Proprietorship, Limited, or Incorporated). However, those who produce at home and do not exceed a certain annual income limit can sell without establishing a company by obtaining the Artisan Exemption Certificate.

In this guide, you will find all the necessary details about the company setup process, store opening steps, and operational management required to start selling on Trendyol.

📌 In 60 Seconds: Is a Company Required to Sell on Trendyol?

• Company Requirement: To sell on marketplaces like Trendyol, Hepsiburada, and n11, it is essential to be a taxpayer and company owner.

• Choice of Company Type: A Sole Proprietorship offers a quick and low-cost start; a Limited company is ideal for those with growth ambitions.

• Application Documents: The tax registration, signature declaration, and company information must be up-to-date.

• Invoice and Operations Management: Manually managing order, invoice, and shipping processes becomes impractical; using digital solutions to manage from a single panel is advantageous.

• Digital Convenience: Thanks to integrators like Üstad, company establishment and operation processes can be conducted quickly and effortlessly.

Is It Mandatory to Establish a Company to Be a Seller on Trendyol?

The first step for everyone who wants to open a store on Trendyol is to own a company. Because:

• It is mandatory to issue an invoice for every product you sell.

• Your income must be taxed.

• You need to make a formal agreement with the marketplace.

Selling without establishing a company poses a legal risk and may lead to the closure of your account.

Can You Sell on Marketplaces Without Being a Taxpayer?

To sell on Trendyol, it is necessary to establish a company and be a taxpayer. However, under the artisan exemption applied in Turkey, individuals who meet certain requirements can sell on marketplaces without establishing a company. 

So, for those asking "Can it be done without establishing a company?" the only exception is the Artisan Exemption. However, this model is limited and not sustainable.

If you are producing at home by your own means (without using machinery) (jewelry, knitting, home-cooked food, etc.):

• You obtain an "Artisan Exemption Certificate" from the tax office.

• You open a commercial bank account.

• Provided you do not exceed a certain turnover limit, you can apply to the marketplace where you wish to work with this certificate and sell without establishing a company.

• In this case, the marketplace deducts a certain withholding tax on your behalf and pays it to the tax office.

Sole Proprietorship or Limited Company for Selling on Trendyol? Which is More Advantageous?

The type of company you choose when opening a store on Trendyol directly affects your business's tax liabilities, operational costs, and growth potential. Considering the e-commerce dynamics of 2026, sellers face three main options: Sole Proprietorship, Limited (LTD), and Incorporated (AŞ) companies. For new entrepreneurs with limited capital, a Sole Proprietorship is the most advantageous choice due to its low setup cost and ability to be opened within 24 hours through the digital tax office. Especially sellers aged 18-29 can minimize their costs by benefiting from the Young Entrepreneur Support thanks to tax exemptions.

If you have business partners or aiming for high turnover in the medium to long term by building a corporate brand, establishing a Limited Company (LTD) will be a more logical step in terms of prestige and a fixed tax rate. As your income rises, transitioning to a Limited structure after a certain turnover threshold will ensure financial sustainability to avoid the progressive tax rate (%15-%40) on sole proprietorships. In summary; a sole proprietorship for speed and low cost, and a limited company for corporateness and high-volume trade should be preferred.

Trendyol Store Opening Process: Step by Step

After deciding to sell on Trendyol, your store approval and readiness for sale usually take 1 to 3 business days. Here are the 6 critical steps you should follow according to the 2026 current regulation:

1. Preparation: Company Establishment and Documents

Since Trendyol does not accept individual applications, the first step is to create a tax liability. You can establish your sole proprietorship in 24 hours through the interactive tax office. Before applying, prepare the digital copies (PDF or JPEG) of the following documents:

• Tax Registration (Up-to-date)

• Signature Circulars or Declaration (Notarized)

• Company IBAN Information (The account to receive payments must be in the company's name)

• KEP Address and MERSIS Number (Mandatory for Limited/Incorporated companies)

2. Filling Out the Application Form

Go to partner.trendyol.com and click the "Become a Seller" button. In the open form, select your company type (Sole, Limited, etc.), tax number, contact information, and main sales category.

SEO Tip: Make sure your store name is memorable and compatible with the product you are selling.

3. SMS Verification and Password Creation

After filling out the form, enter the 6-digit verification code sent to your mobile phone into the system. After this stage, you will set your password to login to the Trendyol Seller Panel.

4. Uploading Information and Documents Through the Panel

Once you log in to your panel, you need to complete the operational details from the "Profile Information" section:

• Shipping Selection: Choose the courier company you want to work with.

• Address Information: Enter invoice address, shipment address, and return depot addresses.

• Document Upload: Upload your prepared tax registration and signature circulars into the system.

5. Digital Contract Approval and Wet Signature

Digitally approve the Trendyol Seller Contract. However, remember; to ensure legal security in 2026 applications, Trendyol may request a physically signed copy of the contract and signature circular by cargo. Sign each page of the contract and send it to the address specified to you.

6. Approval and Product Listing

Your documents are reviewed by the Trendyol team. If there are no deficiencies in your information, your store is activated within 1-3 days. Now you can enter your first stock from the "Add Product" section and start selling to millions of customers!

Invoice and Operations Management

1. Order Management: From Initial Notification to Package

Every order falling into the Trendyol Seller Panel appears in the "New Orders" tab.

• Quick Approval: The quicker you approve the order, the more confidence you give to the customer.

• Stock Control: Always check your physical stock before approving an order; because, according to the rules of 2026, each order canceled due to a lack of stock heavily impacts your store rating.

2. Invoice Management: The Power of Digital Transformation

Invoicing, the legal leg of e-commerce, is now completely digitized.

• e-Invoice Obligation and Integration: As of 2026, using an e-invoice or e-archive invoice is standard for Trendyol sellers. Yet, creating an invoice for each order creates a significant operational burden and error risk during intensive sales periods. Using an integrator software instead of manually preparing invoices automatically matches the invoice with the order information and reduces the error rate to zero. At exactly this point, you can benefit from Yengeç. Yengeç works fully compatible with your Trendyol store, instantly pulls order information, automatically creates your invoices, and reduces error rates to zero.

• Automated Process Management: Instead of wasting time manually creating an invoice, you can manage your e-invoice processes and prepare your shipping labels with a single click thanks to Yengeç’s infrastructure.

• Transmission and Archiving: It is a legal obligation to transmit the digital copy of the created invoices to the customer via the Trendyol panel. Automatic systems carry out this transmission on your behalf, increasing customer satisfaction while freeing you from complaints about "invoice not received".

3. Shipping Process: Fast and Secure Delivery

You've prepared the product, issued the invoice; now it's time to deliver the product to the customer:

• Shipping Barcode: Stick the shipping barcode you obtained from the panel onto the package so that it can be scanned easily by the courier. This barcode is the most crucial document for tracking the product.

• Packaging Quality: Use durable packages suitable for the dimensions/weight ratio of your product. Remember, each product that arrives damaged returns to you as "return cost" and "negative review".

• Delivery Time: Delivering the order within the "shipping time" you committed to will move you up in Trendyol search results.

What Happens If I Try to Sell on Trendyol Without Establishing a Company?

Trying to sell on Trendyol without establishing a company poses serious risks in terms of both platform rules and the Turkish Commercial Code. If you do not have a legal exemption (such as Artisan Exemption) and you are selling without establishing a company, here are the main issues you may face:

• Heavy Tax Penalties and Legal Risks: Earning commercial income without being a taxpayer is considered part of the "underground economy." Because you are obligated to issue an invoice for every product you sell, if it is found that you haven't, you may face retroactive tax penalties, irregularity penalties, and delay interests.

• Store Closure and Blacklisting: Trendyol attaches the utmost importance to seller security. Stores whose company information is not verified or cannot present their legal documents are permanently closed. This situation may not only lead to "blacklisting" on Trendyol but also prevent you from selling in other marketplaces.

• Operational and Financial Barriers: Without a company, you cannot make corporate agreements with cargo companies, nor can you benefit from the discounted cargo brackets offered by Trendyol. Additionally, attempting to withdraw your earnings to a personal account instead of a commercial one can trigger the banks' suspicious transaction radar and lead to the blockage of your account.
