Selling on Trendyol: Store Setup and Commission

01Who Is Selling on Trendyol Right For?

Trendyol, Türkiye's leading online marketplace and one of its most-visited, offers a ready-made customer base. For a business that can't yet bring visitors to its own site, it is one of the fastest ways to speed up first sales. That's why most businesses that want to sell on Trendyol start with the marketplace.

A marketplace, however, is like renting a storefront: the customer belongs to the platform, the rules belong to the platform and a cut is taken from every sale. In highly competitive categories such as fashion, home, cosmetics, food and electronics, price and service quality are decisive. We discussed in detail which model suits you in our marketplace or your own site article.

• Businesses with standard products that aim for fast sales
• Those who want to test demand before driving traffic to their own site
• Sellers who can manage stock and shipping in an orderly way
• Products with a profit margin that can absorb the commission in the price

02Seller Application and Required Documents

On Trendyol you sell as a business with a tax registration, not as an individual. You can apply as a sole proprietorship or a capital company; decide which structure suits you with your accountant. The application is made online through Trendyol's seller application page.

The application usually asks for a tax certificate, a bank account (IBAN) opened in the company's name, a signature circular or signature declaration, trade registry details and contact details. Required documents may vary by company type and the platform's current rules; check Trendyol's seller guide before applying.

1. Prepare your tax registration and company bank account.
2. Fill out the seller application form and choose the categories you will sell in.
3. Upload the requested documents and approve the contract.
4. Log in to the seller panel once your application is approved.
5. Complete your store name, logo, return address and shipping settings.

03How Is Commission Calculated?

Trendyol deducts a commission from every sale, and the rate varies by category. Because commission rates can be updated from time to time, instead of relying on a fixed figure you should check your own category's current rate in the seller panel.

When calculating profitability, take into account not only the commission but also the shipping fee, packaging, possible return costs and campaign discounts. Many new sellers realize at the end of their first months that some products are being sold at a loss; the cause is usually that these items were forgotten in the pricing.

Net profit = Sale price
        - Commission (sale price x category commission rate)
        - Shipping fee
        - Product cost
        - Ambalaj
        - VAT and other taxes
        - Ortalama iade maliyeti

Joining Campaigns

The platform's campaign periods can increase sales, but discount and extra commission conditions squeeze profit. Before joining a campaign, calculate your minimum profit margin on that product; it is possible to lose money while the number of units sold goes up.

04Product Listing: Being Findable

Inside a marketplace, customers find you through search and category filters. Entering the product name, category and attributes correctly directly affects the product's visibility. A product with missing attributes may not show up in filters at all.

Image quality is decisive too. Among dozens of sellers offering the same product, customers prefer the one with sharp photos on a clean background, shot from several angles. For a consistent image set that complies with marketplace rules, you can get product photography support.

In a new store, instead of uploading everything at once, it is healthier to start with a few products that have high margins and safe stock. In the first weeks, track which product is viewed, which is added to the cart and which turns into a sale. This data shows which products to prioritize as you expand the catalog.

• Product name: brand, product type, model and a distinguishing feature.
• Barcode: must be unique for every product and variant.
• Category and attributes: all mandatory fields completed.
• Images: compliant with the platform's size and background rules.
• Description: usage, size, material and care information.

05Shipping Process and Delivery Time

Handing orders to the carrier within the stated time is one of the most important indicators of seller performance on Trendyol. Set a realistic dispatch time on the product page; stating an ambitious time and then failing to meet it lowers your performance score.

Shipping fees are generally determined by the product's volumetric weight (desi) and the platform's contracted carrier terms. For heavy and bulky products, shipping can be a bigger cost item than commission. Instead of labeling orders one by one, a shipping integration that provides bulk labels and automatic tracking numbers saves a great deal of time as orders grow.

• Choose packaging material to fit the product size; empty space increases the volumetric weight.
• Don't neglect protective packaging for fragile products.
• Set the dispatch time according to your warehouse capacity.
• Clarify the return address and the return process from the start.

06Store Score and Customer Communication

In a marketplace, the seller score affects customer trust and therefore sales. Late shipping, seller-caused cancellations, defective products and unanswered customer questions are the main factors that lower the score. A seller-caused cancellation mostly stems from a stock error and is the easiest problem to prevent.

Answering customer questions quickly and politely can turn even a negative review into a trust signal. Professional replies to reviews are also read by other customers who are examining the product.

07Invoicing and Accounting

A legal invoice must be issued to the buyer for every sale made on a marketplace. If the buyer is an e-invoice taxpayer, an e-invoice (the Turkish e-invoicing system) is issued; if not, an e-archive invoice. As the number of orders grows, issuing invoices by hand both takes time and raises the risk of errors; an e-invoice integration that automates this from the order screen keeps things in order.

Marketplace settlements, commission deductions and returns should be tracked separately in accounting. Since tax matters can differ by business, be sure to check current legislation and consult your accountant.

08Growing to Multiple Channels

Once things are running smoothly on Trendyol, many sellers expand to other channels such as Hepsiburada, N11 and Amazon, and to their own site. At that point, managing each channel's panel separately becomes unsustainable. We explained the logic of managing products, stock, prices and orders from a single hub in our what is marketplace integration article; for an example specific to small producers, see our article on marketplace selling for local producers.

In Aurora Smart E-Commerce, the connections to eight marketplaces, Trendyol included, live inside the same panel where you manage your own store; there is no middleware integration program and no extra fee per marketplace. With marketplace-specific price rules and a minimum profit margin, you prevent selling at a loss. Details are on our marketplace integration page.
