Is It Mandatory to Incorporate a Company to Sell on Trendyol?

Selling on digital marketplaces, especially on major platforms like Trendyol, Hepsiburada, and n11, offers a great revenue opportunity, but it also brings a critical question to mind:

Can I open a Trendyol store without setting up a company?

As of 2026, it is mandatory to be a taxpayer, meaning you must have a company (Sole Proprietorship, Limited Liability, or Joint Stock), to open a store on Trendyol. However, individuals who produce at home and do not exceed a certain annual income limit can sell without setting up a company by obtaining a Tradesman Exemption Certificate.

In this guide, you will find all the details you need to know about the company registration process, store setup 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, being a taxpayer and owning a company is mandatory.

• Choosing a Company Type: A sole proprietorship offers a fast and low-cost start, while a Limited Liability Company (LLC) is ideal for those aiming for growth.

• Application Documents: Tax certificate, signature circular, and up-to-date company information are required.

• Invoice and Operations Management: Managing orders, invoicing, and shipping processes manually becomes impossible; managing them from a single dashboard through digital solutions provides a major advantage.

• Digital Convenience: Thanks to integrators like Üstad, company registration and operational processes can be managed quickly and effortlessly.

Is It Mandatory to Set Up a Company to Become a Trendyol Seller?

For anyone wanting to open a store on Trendyol, the first step is owning a company. This is because:

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

• Your income must be taxed.

• You need to sign an official agreement with the marketplace.

Selling without setting up a company poses legal risks and can lead to the suspension of your account.

Can You Sell on Marketplaces Without Being a Taxpayer?

To sell on Trendyol, you must set up a company and be a taxpayer. However, within the scope of the tradesman exemption applied in Turkey, individuals who meet certain conditions can sell on marketplaces without setting up a company. 

In other words, for those asking "Can I do it without setting up a company at all?", the only exception is the Tradesman Exemption. However, this model is limited and not sustainable.

If you produce at home using your own resources (without using heavy machinery) such as jewelry, knitting, home-cooked meals, etc.:

• You obtain a "Tradesman Exemption Certificate" from the tax office.

• You open a commercial bank account.

• Provided you do not exceed a specific turnover limit, you can apply to the marketplace you want to work with using this certificate and sell without setting up a company.

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

Sole Proprietorship vs. Limited Liability Company for Selling on Trendyol? Which One 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 have three main options: Sole Proprietorship, Limited Liability Company (LLC), and Joint Stock Company (JSC). For beginners and entrepreneurs with limited capital, a Sole Proprietorship is the most advantageous choice due to its low setup cost and the ability to register online within 24 hours via the digital tax office. In addition, sellers aged between 18-29 can minimize their costs by taking advantage of the tax exemption provided by the Young Entrepreneur Support.

If you have business partners or want to build a corporate brand with high turnover targets in the medium to long term, establishing a Limited Liability Company (LLC) is a more logical step in terms of prestige and fixed tax rates. To avoid being affected by the progressive tax brackets (15%-40%) of sole proprietorships as your income increases, transitioning to an LLC structure after a certain turnover threshold ensures financial sustainability. In summary; choose a sole proprietorship for speed and low cost, and an LLC for professional corporate branding and high-volume commerce.

Trendyol Store Opening Process: Step by Step

Once you decide to sell on Trendyol, getting your store approved and ready for sales usually takes 1 to 3 business days. Here are the 6 critical steps you need to follow according to the updated 2026 regulations:

1. Preparation: Company Registration and Documents

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

• Tax Certificate (Up-to-date)

• Signature Circular or Declaration (Notary approved)

• Company IBAN Information (The account where payouts will be deposited must be in the company name)

• KEP Address and MERSIS Number (Mandatory for LLCs/JSCs)

2. Filling Out the Application Form

partner.trendyol.com Go to the address and click on the "Become a Seller" button. In the form that opens, select your company type (Sole Proprietorship, LLC, etc.), tax number, contact information, and primary sales category.

SEO Tip: When choosing your store name, make sure it is memorable and matches 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 step, you will set your password to log in to the Trendyol Seller Dashboard.

4. Uploading Information and Documents via the Dashboard

After logging into your dashboard, you need to complete the operational details under the "Profile Information" section:

• Carrier Selection: Mark the shipping carrier you want to work with.

• Address Information: Enter billing, shipping, and return warehouse addresses.

• Document Upload: Upload your prepared tax certificate and signature circular into the system.

5. Digital Agreement Approval and Physical Signature

Approve the Trendyol Seller Agreement digitally. However, keep in mind that in 2026, Trendyol may request a copy of the agreement with a physical signature and the signature circular physically sent via courier to ensure legal security. Download the agreement, sign every page, and send it to the address specified.

6. Approval and Product Listing

Your documents will be reviewed by the Trendyol team. If there are no missing details, your store will become active within 1-3 business days. Now, you can add your first inventory from the "Add Product" section and start selling to millions of customers!

Invoicing and Operations Management

1. Order Management: From First Notification to Packaging

Every order received on the Trendyol Seller Dashboard is visible in the "New Orders" tab.

• Fast Approval: The quicker you approve the order, the more trust you build with the customer.

• Stock Control: Be sure to check your physical stock before approving the order; because according to 2026 rules, every order canceled due to stock shortage deals a heavy blow to your store score.

2. Invoice Management: The Power of Digital Transformation

Invoicing, the legal side of e-commerce, is now fully digitized.

• e-Invoice Obligation and Integration: As of 2026, using e-invoices or e-archive invoices is standard for Trendyol sellers. However, creating invoices individually for each order during peak sales seasons creates a massive operational burden and risk of errors. Instead of issuing invoices manually, utilizing integration software automatically matches order info with the invoice, reducing the margin of error to zero. Right at this point, you can benefit from Yengeç. Yengeç works in perfect sync with your Trendyol store to pull order details instantly, automatically generate your invoices, and reduce the margin of error to zero.

• Automated Process Management: Instead of wasting time with manual invoicing, thanks to the infrastructure provided by Yengeç, you can manage your e-invoice processes and prepare your shipping labels with a single click.

• Delivery and Archiving: Delivering a digital copy of the generated invoices to the customer through the Trendyol dashboard is a legal requirement. Automated systems handle this delivery for you, boosting customer satisfaction and saving you from "I didn't receive my invoice" complaints.

3. Shipping Process: Speed and Secure Delivery

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

• Shipping Barcode: Paste the shipping barcode generated from the dashboard onto the package so the courier can easily scan it. This barcode is the most important document that tracks the product.

• Packaging Quality: Use durable packages suitable for your product's dimensional weight. Remember, every product that arrives damaged returns to you as a "return cost" and "bad review".

• Delivery Time: Shipping the order within your promised "handling time" pushes you to the top of Trendyol search results.

What Happens If I Sell on Trendyol Without Setting Up a Company?

Trying to sell on Trendyol without establishing a company carries serious risks in terms of both platform policies and Turkish Commercial Law. If you do not have a legal exemption (such as the Tradesman Exemption) and are selling without setting up a company, the main issues you may face are:

• Heavy Tax Penalties and Legal Risks: Generating commercial income without being a taxpayer is classified under "informal economy". Since you are required to issue an invoice for every product you sell, if it is determined that you did not issue invoices, you may face retroactive tax penalties, non-compliance fines, and delay interests.

• Store Closure and Blacklisting: Trendyol prioritizes seller security at the highest level. Stores that fail to verify their company information or submit their legal documents are permanently suspended. This situation can lead to you being "blacklisted" not only on Trendyol but on other marketplaces as well, preventing you from ever selling again.

• Operational and Financial Obstacles: Without a company, you cannot make corporate agreements with shipping carriers, meaning you cannot benefit from discounted shipping rates offered by Trendyol. Additionally, attempting to withdraw the money you earn to a personal bank account instead of a business account may trigger bank security reviews for suspicious transactions and lead to your account being blocked.
