24/7
Monitoring and execution — no humans needed
Pricing, analytics, data parsing, research: the routine runs around the clock — including while you sleep.
AI workflows · Custom software · For marketplace sellers
Custom AI automation, embedded into your business processes.
We build AI agents and bespoke workflows for Amazon, Allegro and other marketplaces — integrated into your team’s process, not bolted on as another tool.
Trusted by sellers operating across Amazon, Allegro and EU marketplaces.
More profit · Less overhead · Work that runs itself
This is not AI for the sake of the trend.
It cuts future spend on specialists, takes the routine off your team — and above all, makes you more dangerous to your competitors.
$5–10K
saved every month
The average saving on staff you no longer need to hire, redundant software, and everything you hand over to automation.
Your CRM
built around your metrics and your automation
Your own system, shaped to your needs: the numbers that matter to you, the automation that fits exactly you. That is the next few years — arriving early.
Sound familiar?
You open Seller Central in the morning. Fourteen things need checking. Again.
Prices
A competitor cut their price at 3 a.m. You are finding out just now.
Listings
One of your listings went suppressed — and sat like that all night.
Stock
Your bestseller has 12 days of stock left. The reorder window was last week.
Reimbursements
Amazon owes you money for lost and damaged inventory. The claims never got filed — again.
Fees
Amazon fees went up 12% last year. Your prices never caught up fast enough.
Reports
The owner report is built by hand again: exports, spreadsheets, copy-paste.
Research
New-niche research has been sitting in the “when there is time” list for three weeks.
That is a morning without a system. And that was only seven of the fourteen.
And Sunday you spend in Seller Central again — not with your family.
Tools and metrics are scattered, every decision is made by hand — and every missed decision costs money. Humans cannot keep up. AI agents can — and should.
With SellerUp agents the morning looks different: by 7:00 the digest is already in your Telegram.
- Prices adjusted
- Reorder calculated
- Report built
- Research done
All that is left are the decisions that should not happen without you.
What we build
Workflow automation. AI agents. Custom software.
End-to-end engineering for marketplace sellers — built around your data, your operations, your goals. Not a SaaS subscription. A system that becomes part of your team.
AI agents in your process
Agents that watch listings, prices, inventory, ads, and supply chain — and act on rules you define. Plugged into the tools you already use.
Workflow automation
We map your operations, find the repetitive bottlenecks, and ship pipelines that run on their own — keeping your team focused on strategy.
Custom software
Internal dashboards, server-side platforms, integrations with marketplaces and suppliers. Built specifically for how your business actually works.
One system
Stop running your marketplace through disconnected tools.
Signals come in messy — prices, ads, stock, competitors. SellerUp agents sit in the middle: they decide what matters, route the work, and execute inside your guardrails.

Recent work
Three problems we built solutions for.
Each case is a production system shipped for a real seller. Short summaries below — full write-ups linked under each card.
01 Supply chain · Forecasting
Forecasting delivery and procurement from China to Amazon and other marketplaces.
Custom pipeline that predicts inbound timing, reorder windows, and out-of-stock risk across Amazon and other marketplaces — factoring supplier lead times, freight routing, and inventory burn rate.
Read the case study 02 Operations · Amazon
Custom internal system for an Amazon seller.
Server-side platform unifying stock, orders, suppliers, and resource planning. One source of truth for the operations team — instead of seven scattered spreadsheets.
Read the case study 03 Multi-marketplace · Aggregation
Unified data layer across European marketplaces.
Connectors for Allegro, Amazon, Kaufland, Castorama and others — sales aggregation, ads orchestration, unit economics, and operational dashboards in one place.
