Erli: is anotherchannel worth adding?
A new channel tempts you with the promise of extra orders. Before you count the profit, check what the commission is actually charged on: on Erli the base is wider than the rate table suggests.
Every figure in this text comes from two of Erli's own documents: Annex 3, "Commission Rules", in force since 1 February 2026, and the Price List, Annex 1, in force since 3 March 2026. We checked them on 1 September 2026. Price lists change, so if you are reading this later, look at the Terms section on Erli. The structure of the bill is unlikely to change, and that is what matters most here.
What the commission is charged on
One sentence changes the whole calculation. Erli charges its commission on the price of the item sold together with the cost of the delivery the buyer chose; the terms call that sum the final price. There is one exception: if the buyer does not pay for delivery because it goes through Erli PRO or costs 0 zł, the delivery cost does not enter the base.
The second exception covers offers in the ERLI MobileGo programme: there the base also includes half of the price cut that the marketplace itself applied. The commission is always a gross amount, so taxes, VAT included, are already in it. You get one invoice for commissions a month, and since 1 February 2026 it is a structured invoice in the KSeF system.
Rates and the minimum
The rate depends on the category. In the price list in force since 3 March 2026 the range runs from 2.93% to 19.86%, and some categories use a threshold formula instead of a plain percentage: a fixed amount above a certain price plus a percentage of the excess, sometimes with a cap on the commission. The minimum commission is 0.15 zł, unless a category states otherwise.
If a product fits several categories at once, Erli charges the commission from the one with the highest rate. With a wide catalogue that detail is worth checking: a category picked in passing can raise the bill without you noticing.
The real rate is higher than the one in the table
Erli's own price list shows this best. A buyer takes an item for 100 zł and picks delivery for 15 zł. The final price is 115 zł, and in a category with a 5.26% rate the commission comes to 6.05 zł. Now measure that against what you actually sold: 6.05 zł on a hundred złoty of goods is not 5.26% but 6.05%. The cheaper the product and the dearer the delivery, the bigger the gap grows, on an item for 30 zł with delivery for 15 zł the commission is charged on 45 zł, one and a half times the price of the item itself.
When the channel is worth adding
The channel makes sense when your margin, after a commission charged on the final price, is still positive. Do the maths on your worst items, not your best: on a product with a thin margin and expensive shipping, a commission on the final price can turn the bill over even when the shop average looks calm.
The second thing is handling. A new channel is a new source of orders, returns and questions, and all of them have to come off the same stock as the shop. If stock is not shared, the first oversell of the season costs more than the whole channel earned.
The conclusion is not that Erli is expensive. It is this: calculate the commission on the final price, not on the product price, and check the rate in your category before you count the profit from a new channel. If the margin survives that calculation, the channel makes sense, and keep the stock shared with your shop either way.
