What SellAuth costs
SellAuth is the closest competitor to Komerza on philosophy: 0% transaction fees on every plan, funded by subscriptions rather than a cut of your sales, aimed squarely at digital goods sellers who connect their own payment processors. Anyone comparing the two is choosing between two platforms that agree on the fundamental point. The differences are in the limits and in what each plan includes.
Every SellAuth plan caps how many products you can list: 50 on Base, 500 on Business and 5,000 on Scale. Scale also caps team members at 50.

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 SellAuth stops
SellAuth is built for the small seller, and its pricing says so: every plan caps products, at 50, 500 and 5,000, and the top plan caps the team at 50. A platform that puts a ceiling on its most expensive plan is describing the size of store it expects to host, and it is why you do not see large stores on it. Komerza has no cap on any plan, including the free one, and its largest stores clear over €200,000 a month on the same plans anyone can sign up for.

When SellAuth is the better choice
- You want the lowest monthly price and you fit inside the caps. SellAuth's paid plans are cheap, and if you list a handful of products that difference is real money.
- You want a reseller panel on a low-cost plan. SellAuth puts it on Scale; on Komerza it starts at Premium, so the two are close, and Scale bundles more alongside it.
- You are already running there and none of the limits below are near you. Both platforms take 0%, so there is no fee argument for switching.
When to switch to Komerza
- You intend to grow. SellAuth's plans stop at 50, 500 and 5,000 products and 50 team members, which is a platform built for small stores. Komerza has no cap on any plan, and the largest stores on it clear over €200,000 a month. If you sell licence keys or game top-ups at scale, this is the difference that eventually forces a migration, so make it before you have to.
- You have a team larger than 50, or you want team members on the free plan. Komerza includes team members on every plan with no cap, with per-member permissions and an audit log.
- You want the store to be more than a theme. Komerza's AI builder edits the whole site from a chat, exposes the source code with hot reload, and keeps version history you can roll back.
- You want email marketing from your own domain, cart recovery, a built-in blog and a customer portal from the same platform rather than a separate tool.
- You want to run the store from your phone. Komerza ships iOS and Android apps for managing products, orders and revenue, with push alerts on every sale.
- Moving is one click. Komerza imports your SellAuth products, orders and customers directly; you pick the store from a list and it runs.
