The Real Cost of Opening a Trendyol Store (2026)

First, the answer everyone is looking for: registering as a seller on Trendyol is free. You do not pay Trendyol any entry fee to apply. But the sentence "store opening fee is 0 TL" does not mean "becoming a Trendyol seller is free": the real cost builds up off the platform — company setup, an accountant, inventory capital, a shipping-and-return buffer and an ad budget. In this article we break down those line items one by one, build a first-month simulation around a 50-product boutique scenario, and show the deductions that kick in once you start selling. The goal is not to discourage you; it is to keep you from starting with an incomplete budget because "it was supposedly free" and running out of cash by the third month.

Short answer: registration is free, the cost starts with sales

Trendyol's revenue model is not a membership fee but a per-sale deduction: the category commission, a per-order platform service fee and the shipping fee. In other words, while your store sits idle you pay Trendyol nothing; you pay as you sell. This means your startup cost gathers in two separate pockets: what leaves your pocket before any sale (company, accountant, inventory, equipment) and what is deducted from your payout after a sale (commission, service fee, shipping, withholding tax). A seller who does not calculate these two separately sees revenue coming in yet cannot figure out where the money went. We covered the sales process end to end in the guide to selling on Trendyol; this article is the budget side of the job.

Before selling: company, accountant, tax setup

1. Company setup — the first and mandatory step

A Trendyol seller application asks for your tax certificate and company details; in other words, you must have a business before you start selling. The first decision is the company type: most newcomers start with a sole proprietorship because of its low setup and closure cost; if there is a partnership structure, a growth plan or a need to limit liability, a limited liability company stands out. Setup cost varies by type, by the notary and by the accountant's opening fee — get the exact figure from your accountant before you apply. We compared the tax, cost and liability differences between the two types in detail in the sole proprietorship vs. limited company article.

2. Accountant — a regular monthly expense

In e-commerce, tax returns, the e-invoice/e-archive setup and the bookkeeping of marketplace records practically cannot be run without an accountant; budget this item not as "optional" but as a fixed monthly expense. The fee varies by city, business volume and company type; the minimum fee schedule sets a floor but actual quotes differ — get quotes from several accountants, asking about their e-commerce experience. The general rule here applies to the whole article too: for the precise situation on tax and compliance matters, consult your accountant.

3. VAT and withholding tax — obligations built into the price

The moment you become a seller you start living with two tax mechanisms. The first is VAT: the sticker price on Trendyol is VAT-inclusive; a portion of that price is tax you collect from the customer on behalf of the state, and it is not your money. The net VAT you will pay is found by subtracting the VAT on your purchase and expense invoices from your sales VAT — the whole mechanism is in the guide to VAT in e-commerce. The second is 1% e-commerce withholding tax: its base is the VAT-exclusive amount, it is deducted from your payout and offset against your income/corporate tax at year end — so it is not an extra tax but a prepaid one; you can work out the figure with the withholding tax calculator. Both look like a "cost" but actually behave differently; putting them into your profit calculation wrong distorts your margin in both directions.

Getting ready to sell: where the capital actually goes

4. Product and inventory capital — the biggest item

By far the largest part of the startup budget is inventory. There are two extreme mistakes here: starting with deep stock of a single product (if it does not sell, your capital gets locked up) and starting with one unit each of a hundred varieties (when sales come in, running out of stock hits your store rating and the Buybox). A balanced start is enough depth to carry sales across a limited range of varieties — in the simulation below we will use 50 varieties × 3 units. Product selection itself is a separate article; while deciding where to tie up your capital, set up the profit math in advance per product with the Trendyol profit calculator — do not commit inventory before you see what is left in your hand after commission, shipping and the return share are subtracted from the sale price.

5. Shipping-and-return buffer — the first month's surprise

The shipping fee is set by Trendyol's negotiated rate schedule. Under the 13 July 2026 tariff, orders of 10 desi or less use the 0–199.99 TL and 200–349.99 TL brackets; orders at 350 TL or more, or packages above 10 desi, use the full desi tariff. Both are published VAT-exclusive; when deducted from your payout, 20% VAT is added on top. The real surprise is in returns: even when the outbound shipping is returned it does not come back, the return shipping may stay on you depending on the reason, and the product does not always come back in sellable condition. As we calculated line by line in the return cost article, the real cost of a single return on a medium-sized product reaches the ~230 TL band. For the first month, assume the return rate not optimistically but realistically (15–25% is typical in textiles) and set this money aside in your startup budget as a buffer; you can calculate it for your own product with the return cost calculator.

6. Starting ad budget — visibility is not free

A new store has no reviews, no sales history and no organic ranking; a significant share of your first orders comes from ads. Set the first month's budget not as "let me make a profit" but as a learning budget: which product gets clicks, which keyword converts, what your real ACoS/ROAS is. Ad spend without a ROAS target above your break-even point grows revenue while eroding profit — we explained how to calculate the target in the what should ROAS be article.

First-month simulation: a 50-product boutique scenario

Now let us gather it all into a single table. The assumptions are transparent and deliberately modest: 50 product varieties, 3 units of stock per variety (150 units), an average unit purchase cost of 120 TL; a target of ~60 orders in the first month and a 15% return rate (~9 returns, ~230 TL per return); a 3,000 TL learning budget for ads. Change the figures to fit your own category — the table is a template, the numbers are an example.

So the practical meaning of the phrase "registration is free," in this scenario, is ~26,000 TL of startup capital + setup and accountant expenses. And a note on timing: the inventory and ad money go out up front, while the sale proceeds land at the payout due date — in the first weeks a "I sold it but the money is not in my account" period is normal, and that is exactly why the buffer is needed. We explained the due-date mechanism in the Trendyol payment terms article. Do not let this figure scare you: the same scenario can pay for itself with the right product at the right price; what should scare you is starting without ever doing this calculation.

Hidden costs: per-sale deductions

The startup budget is half the job; the other half is the items deducted from your payout on every sale. All three are "hidden" because a new seller looking at the sticker price sees none of them:

• Category commission: deducted as the VAT-inclusive sale price × the rate shown in the panel; the invoice is issued VAT-inclusive, with no extra VAT added on top. The rate varies by category and period — for current rates and the category breakdown see the commission rates article, and verify your own exact rate from the panel.
• Platform service fee: deducted per order; its amount varies by the rate schedule and the program you are enrolled in, so verify the current amount from your panel. It looks small, but on a low-priced product it takes a sizeable slice of your margin.
• Shipping fee: deducted from the desi (Trendyol's volumetric weight unit)/bracket schedule, with 20% VAT added on top of the VAT-exclusive published bracket. On a cheap product, shipping can be a bigger item than the commission.

Beyond these three, dozens of deduction types circulate in the statement — penalties, disputes, return lines and more; we explained what each of them means, one by one, in the glossary of deduction types. The habit a new seller should build in the first month is this: open the account statement every week and match the deductions to the sales lines. If there is a line you cannot explain, query it.

Frequently asked questions

How much does it cost to open a store on Trendyol?

Registration fee paid to Trendyol: 0 TL. Total startup cost: it depends on your product and your ambition. In the modest 50-product scenario above it came to ~26,000 TL + setup and accountant expenses; with a more expensive product or deeper stock this figure multiplies, while in dropshipping-like models it drops but other risks arise.

Does Trendyol charge a monthly fee or membership fee?

No fee is charged for registration; the ongoing cost is not a fixed membership fee but per-sale deductions (commission + service fee + shipping). Verify the current application terms and rate details from Trendyol's seller application page and from the panel.

Can I sell on Trendyol without setting up a company?

The application asks for a tax certificate and business details; in practice the path runs through setting up a sole proprietorship or limited company before selling. Assess which one suits you from the sole proprietorship vs. limited company article, verify the current application requirements with Trendyol, and the tax consequences with your accountant.

Calculating the cost once is not enough — you have to track it every month

The table in this article is for opening day; the real game starts in the second month. Once the commission, service fee, shipping and return deductions are spread across hundreds of order lines, the answer to "am I making a profit" does not appear on a single screen in the panel. Verimle exists precisely for this gap: when you connect your Trendyol account, the Profit X-Ray calculates the real profit per product including deductions and the return burden, the payout reconciliation compares the expected deduction with the actual one, and it detects unexplained deductions and prepares a dispute draft. Explore the features — with the 14-day Pro trial you can see it on your own data. And before you open your store, work out your first product's real margin in two minutes with the profit calculator; decide which product to tie your capital to based on that figure.

One final reminder: the cost and deduction items in this article (commission, platform service fee, shipping, opening fee and so on) are illustrative examples; they change over time and by category and by your agreement, and they do not replace Trendyol's current official terms or your own seller contract. Verify the current application terms from Trendyol's Trendyol Application Process page, and the exact and current rate and fees that apply to you from the Trendyol Seller Panel. Before you decide, re-run the net profit and cost calculation with your own numbers using the profit calculator. This guide was reviewed on 18 July 2026.
