What Sell.app costs
Sell.app is a digital goods platform aimed at the same market as Komerza: licence keys, game currency, accounts and files, with the seller connecting their own payment processors. It offers two ways to pay, a percentage of each sale or a flat monthly plan, which makes the comparison with Komerza unusually direct.
Payment processor charges are separate and set by the processor, on Sell.app and on Komerza alike.
Sell.app figures verified on 7 September 2026 against Sell.app pricing, Sell.app. Check there for current rates.
Sell.app takes
3% per sale on the Standard plan
Monthly: None on Standard, or $199.99/mo on Advanced for 0% platform fees
Komerza takes
0% on every plan
No payout, dispute, affiliate or fraud-tooling fees on any plan
Built for scale
Built for everyone. Engineered for the top end.
Globally, Komerza sellers do over €2 million a month, and the largest single stores clear over €200,000 a month. There is no product cap, no team cap and no revenue ceiling on any plan, so the store you start with is the store you scale, without a migration in the middle.
Where Sell.app stops
Sell.app's 3% is fine at small volume, and that is the plan it is built around. Past that, the only way off the percentage is a $199.99-a-month plan, which is where a store that has grown finds out what the platform was really priced for. Komerza is 0% on every plan from the first sale, and its largest stores clear over €200,000 a month without ever having changed plan to get the rate.
What it costs you
A percentage and a flat monthly fee cross over at some point, and where that point falls depends entirely on your numbers. Put your own in and see what Sell.app and Komerza each cost at that volume.

When Sell.app is the better choice
- You are selling very little. 3% of a few hundred euros a month is a couple of euros, and no subscription competes with that.
- You are already set up on Sell.app and your volume sits in the band where 3% costs less than a monthly plan.
When to switch to Komerza
- You want 0% fees without paying for them. Komerza's free plan is 0% transaction fees; on Sell.app removing the 3% costs $199.99 a month.
- Your revenue is high enough that 3% is a meaningful number. At €10,000 a month that is €300, every month, for the same platform features.
- You want email marketing and cart recovery in the same platform rather than as separate tooling.
- You want a store you can take further than a template: an AI builder that edits the whole site, source code you can open, a built-in blog and reviews, and a reseller network.
- Moving is one click. Komerza imports your Sell.app products, orders and customers directly; you type your store handle and it runs.

What people ask when they are weighing Sell.app against Komerza, answered with the same figures as the table above.
Sell.app's pricing page lists a Standard plan at 3% per sale with no monthly cost, and an Advanced plan at $199.99 a month with 0% platform fees. Payment processor charges are separate. Verified on 7 September 2026 from sell.app/pricing.
Komerza charges 0% transaction fees on every plan, including the free one, so reaching 0% costs nothing. On Sell.app, 0% platform fees are on the $199.99/mo Advanced plan. At 3%, Sell.app's Standard plan costs more than a flat Komerza plan once you are past a few hundred euros in monthly sales, before either platform's processor fees. Put your own numbers into the calculator above.
Yes. Both are built for digital goods and both support crypto payments, licence key delivery and Discord roles. The differences are in fee structure, how far the builder goes (Komerza's AI builder edits the whole site and exposes the source code), and the email marketing, cart recovery, reseller network, blog and reviews that Komerza includes.
Yes. Komerza's migration tool imports products, orders and customers from Sell.app directly; you enter your store handle and it runs in the background. Product images and store credit balances are not carried over and need recreating by hand. The migration guide covers what to expect.
