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

Selling on digital marketplaces, especially on major platforms like Trendyol, Hepsiburada and n11, offers a great income opportunity while also bringing up this critical question:

Can I open a Trendyol store without establishing a company?

As of 2026, in order to open a store on Trendyol, you must be a taxpayer, meaning you must have a company (Sole Proprietorship, Limited Company or Joint Stock Company); this is mandatory. However, people who produce at home and do not exceed a certain annual income threshold can also sell without establishing a company by obtaining a Tradesperson Exemption Certificate.

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

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

• Company Requirement: To sell on marketplaces like Trendyol, Hepsiburada and n11, you must be a taxpayer and own a company.

• Company Type Selection: A sole proprietorship provides a fast and low-cost start; a limited company is ideal for those aiming to scale.

• Application Documents: Tax plate, signature declaration and company information must be up to date.

• Invoice and Operations Management: Order, invoice and shipping processes become impossible to manage manually; managing them from a single dashboard with digital solutions provides an advantage.

• Digital Convenience: Thanks to integrators like Üstad, company setup and operational processes can be carried out quickly and effortlessly.

Is it mandatory to set up a company to become a seller on Trendyol?

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

• An invoice must be issued for every product you sell this is mandatory.

• Your income must be taxed.

• A formal agreement with the marketplace is required.

Selling without establishing a company creates legal risk and may lead to your account being closed.

Can you sell on marketplaces without being a taxpayer?

To sell on Trendyol, you need to set up a company and be a taxpayer. However, under the tradesperson exemption applied in Turkey, people who meet certain conditions can also sell on marketplaces without establishing a company. 

So; for those asking, 'Can't it be done without setting up any company at all?', the only exception is the Tradesperson Exemption. However, this model is limited and not sustainable.

If you produce at home using your own means (without using machines) (jewelry, knitting, home-cooked meals, etc.):

• You obtain a 'Tradesperson Exemption Certificate' from the tax office.

• You open a commercial bank account.

• Provided that a certain turnover limit is not exceeded, you can apply to the marketplace you want to work with using this certificate and sell without establishing a company.

• In this case, the marketplace makes a certain withholding deduction 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 obligations, operational costs and growth potential. Considering 2026 e-commerce dynamics, sellers have three main options: Sole Proprietorship, Limited (LTD) and Joint Stock (AŞ) companies. For new entrepreneurs with limited capital, a Sole Proprietorship is the most advantageous choice because of its low setup cost and the ability to open it within 24 hours via the digital tax office. Especially sellers aged 18-29 can minimize their costs by benefiting from the Young Entrepreneur Support and tax exemption.

If you have business partners or want to build a corporate brand with high turnover goals in the medium to long term, setting up a Limited Company (LTD) will be a more sensible step in terms of prestige and fixed tax rate. As your revenue increases, to avoid being affected by the progressive tax brackets in sole proprietorships (%15-%40), transitioning to a limited structure after a certain turnover threshold provides financial sustainability. In short; choose sole proprietorship for speed and low cost, and limited company for corporate identity and high-volume trade.

Trendyol Store Opening Process: Step by Step

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

1. Preparation: Company Setup and Documents

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

• Tax Plate (Current date)

• Signature Circular or Declaration (Notarized)

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

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

2. Filling Out the Application Form

partner.trendyol.com adresine giderek 'Become a Seller' buttonuna tıklayın. Açılan formda; company type'nizi (Sole Proprietorship, Limited, etc.), tax number, contact information and main sales category'nizi seçin.

SEO Tip: When choosing your store name, make sure your brand is memorable and aligned with the product you sell.

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 so you can log in to the Trendyol Seller Panel.

4. Uploading Information and Documents via the Panel

After logging into your panel, you need to complete the operational details from the 'Profile Information' section:

• Shipping Selection: Determine the shipping carrier you want to work with.

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

• Document Upload: Upload the tax plate and signature circulars you prepared into the system.

5. Digital Contract Approval and Wet Signature

Approve the Trendyol Seller Agreement digitally. However, please note that in 2026 applications, Trendyol may request the wet-signed copy of the agreement and the signature circular physically by courier in order to ensure legal security. Download the agreement, sign every page and send it to the address specified to you.

6. Approval and Product Listing

Your documents will be reviewed by the Trendyol team. If there are no missing details, your store will be activated within 1-3 days. You can now enter your first stock from the 'Add Product' section and start selling to millions of customers!

Invoice and Operations Management

1. Order Management: From First Notification to Package

Every order that lands in the Trendyol Seller Panel appears in the 'New Orders' tab.

• Quick Approval: The faster you approve the order, the more trust you build with the customer.

• Stock Control: Before approving the order, always check your physical stock; because according to the 2026 rules, every order cancelled due to insufficient stock deals a heavy blow to your store score.

2. Invoice Management: The Power of Digital Transformation

Invoicing, the legal backbone of e-commerce, has now become fully digital.

• e-Invoice Requirement and Integration: As of 2026, the use of e-invoice or e-archive invoice is standard for Trendyol sellers. However, creating an invoice one by one for every order creates a significant operational burden and risk of errors during high-sales periods. Instead of issuing invoices manually, using an integrator software brings the error margin to zero by automatically matching the invoice with order details. This is exactly where you can benefit from Yengeç. Yengeç works in full harmony with your Trendyol store, instantly pulls order information, automatically creates your invoices and reduces the margin of error to zero.

• Automated Process Management: Instead of wasting time issuing invoices manually, you can manage both your e-invoice processes and prepare your shipping slips with a single click thanks to the infrastructure offered by Yengeç.

• Transmission and Archiving: Sending a digital copy of the generated invoices to the customer through the Trendyol panel is a legal requirement. Automated systems do this for you, increasing customer satisfaction while also saving you from 'my invoice never arrived' complaints.

3. Shipping Process: Speed and Secure Delivery

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

• Shipping Barcode: Stick the shipping barcode you received from the panel on the package in a way that the courier can easily scan it. This barcode is the most important document for tracking the product.

• Packaging Quality: Use durable packages appropriate for your product's dimensional weight (size/weight) ratio. Remember, every damaged delivery comes back to you as 'return cost' and 'negative review'.

• Delivery Time: Delivering the order within the promised 'handover to carrier time' moves you up in Trendyol search results.

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

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

• Heavy Tax Penalties and Legal Risks: Earning commercial income without being a taxpayer is considered part of the 'unregistered economy'. Since you are obliged to issue invoices for every product you sell, if it is determined that you did not issue invoices, you may face retroactive tax penalties, irregularity fines and late payment interest.

• Store Closure and Blacklist: Trendyol places the highest priority on seller safety. Stores whose company information cannot be verified or who cannot provide legal documents are permanently closed. This may cause you to be blacklisted not only on Trendyol but also on other marketplaces, preventing you from selling again.

• Operational and Financial Barriers: When you do not have a company, you cannot make corporate agreements with shipping companies or benefit from Trendyol's discounted shipping rates. Also, trying to withdraw the money you earn to your personal account instead of a business account may trigger the suspicious-transaction radar of banks and lead to your account being blocked.
