How to Find the Money Leaking on Trendyol: 3 Leak Points (2026)

If your revenue is large but what stays in your pocket at month-end is small, money is leaking somewhere — and usually not from one place, but from three. These three are different items, they sit on different screens, and crucially the same lira must not be counted twice. In this article we split the leaking money into three leak points, and explain how to measure each one, how to track the money that comes back, and how to see your cash flow in advance. First, check whether the profit you expect is set up correctly with the Trendyol Profit Calculator — some leaks come from the cost being miscalculated in the first place.

Why a "single total" misleads

Answering "how much did I lose this month?" with a single number is tempting but misleading. Because the sources of loss differ: some is recoverable (unfair deductions — you dispute them), some is structural (you are selling a product at a loss — a price/cost decision), and some is waste (an ad running below breakeven). Adding the three together risks double counting (excess shipping can show up both as a deduction and as a product loss) and buries what you should do. The right approach: measure the three separately and take a separate action on each.

Leak 1 — Recoverable deductions

The most infuriating but most hopeful item: money you can get back because it was deducted unfairly. It has two typical sources. The first is commission: on a given order, commission may have been charged noticeably higher than that product's normal rate. The second is shipping: the parcel you calculated as 2 desi may have been measured and invoiced at 4 desi; the difference silently leaves your payout on every shipment.

How to measure: match the commission line on the statement with the sale of the same order number; flag the part charged above the product's usual rate. Each shipment's desi appears in the shipping invoice items — compare it with your own measurement. These two items are the most recoverable types of deduction. We walked through the whole process in the unfair deduction dispute guide, and broke down why a payout lands short, item by item, in this article.

Leak 2 — Products sold at a loss

This loss is not recovered; because the mistake is not yours to dispute, it is in the price/cost structure. You are selling a product at a point where, once commission + shipping + withholding + VAT + product cost are added up, the total exceeds the sale price. Every sale grows your revenue but pulls your net profit negative — and this is invisible when you look at the revenue chart.

How to measure: compute net profit per product (for products without a cost entered, "net" is not meaningful — keep those separate). The total loss of products whose net comes out negative is the size of this leak. The action is different: not a dispute, but a decision to raise the price, cut the cost, or delist the product. Remember that commission is calculated on the VAT-inclusive price; the is commission VAT-inclusive article explains the common mistake at this point.

Leak 3 — Wasteful ads

If an ad spend is greater than the margin it brings, it is losing you money. The breakeven point is simple: if a campaign's revenue × your margin does not cover that campaign's spend, the campaign is at a loss. Do not let a ROAS of 3 fool you — if your margin is low, your breakeven ROAS may be 4, meaning even a ROAS of 3 is a loss.

How to measure: for each campaign compute spend − (revenue × margin); the sum of the positive ones is the size of the ad waste. The action: stop campaigns below breakeven or narrow their audience. We covered how to read ad returns in the what ROAS should be article.

Three leaks, three separate actions

Measure what comes back — do not settle for "I got it back"

When a deduction you disputed is accepted, the money returns to your account as a return invoice. The discipline here: "I filed a dispute" and "the money came back" are not the same thing. Measure the amount that actually came back by matching the return invoice with its order; summed quarter by quarter, you get a clear answer to "what did the dispute effort really earn?". You cannot manage a gain you do not measure.

See your cash flow in advance

As much as stopping the leak, knowing when and how much will come in matters too. Trendyol payments land not on the order day but once maturity is reached; you can see how much comes in which week from the confirmed payment schedule in advance. This lets you set your stock and ad budget against real cash — without counting sales that have no scheduled date, without overstating. We explained the maturity logic in the Trendyol payment terms article.

Tracking this by hand collapses at scale

Finding these three leaks by hand takes an afternoon at 20 orders; it becomes impossible at 500. When you connect your Trendyol account, Verimle gathers these three leaks at the top of your panel separately — never merged into one total: disputable deductions, loss-making products, and (when you upload your ads report CSV) ads below breakeven. For suspicious deductions it prepares a dispute draft with line references; sending it stays with you, and it measures the money that comes back, quarter by quarter. On the same panel you find your cash flow based on the confirmed payment schedule and, at month-end, the accountant-ready VAT/withholding/commission summary. You can review which items are caught on the Lost Money Radar, Cash Flow Forecast and Accounting Summary pages.

One last reminder: the three leak points here are a guide; they do not replace your own payout statement or your contract. The deduction items, the commission and shipping rates, and the return rules vary by your contract and by period — so before flagging an item, verify your own payout and deduction items in the Trendyol Seller Panel, and check the current official terms and rates in the Trendyol Seller Information Center. To set up the profit you expect correctly from the start, you can use the Trendyol Profit Calculator. This guide was reviewed on 18 July 2026.
