FAQ: AI automation for marketplace sellers

Is this a subscription to your product?

No — you are buying a build, not a licence. We design the automation around your business, it runs on your infrastructure, and the code and data belong to you. There is no per-seat fee and no dependency on a SellerUp product staying alive. After launch you either keep us on support or take the system over with documentation and training.

Which marketplaces do you work with?

Amazon is the core, and Allegro is the second line, with a dedicated service track for the Polish market. Beyond those we build integrations for Kaufland, Castorama, Leroy Merlin, eMAG, Bol and other European platforms. If a platform publishes a usable API, an agent can read and write against it; if it does not, we will say so before you commit.

How autonomous are the agents?

Exactly as autonomous as you make them. Every agent runs between two poles you choose: “notify only”, where it watches and reports, and “act within limits”, where it changes prices, budgets or listings inside boundaries you define. Critical decisions can always stay with a person, and the limits are settings you can tighten at any point.

What can an agent actually take over?

The repetitive parts of marketplace operations. In practice that means listing and buy-box monitoring, repricing on your own margin and competitor logic, stock control with reorder points and out-of-stock risk, daily ad checks with stop-rules for money-losing targets, and review requests with drafted replies. Anything that is a judgement call stays with your team.

How do the agents connect to our systems?

Through the marketplaces’ own documented APIs and the tools you already run. On Amazon that is the Selling Partner API; on Allegro the Allegro REST API. Agents reach your internal tools through the Model Context Protocol, which gives them scoped access rather than a blanket key. Every interface we use is linked above this FAQ.

Why does an agent poll on a schedule instead of watching live?

Because marketplace APIs enforce rate limits. Amazon’s SP-API publishes usage plans that cap how often an application may call each endpoint, so an agent that hammered the API continuously would simply be throttled. We set polling frequency per task — prices and stock more often, settlement data less — so the important signals arrive early without burning your quota.

What does it cost?

Automation work is quoted per project — we do not publish a rate, because the price is driven by how many processes are in scope, how many platforms and internal systems the agents have to reach, and whether you want us on support afterwards. Describe the task and we come back with a range within one business day.
