Margins you can trust
True profit per SKU after fees, returns and landed cost, built on each unit's actual cost. It feeds your monthly close.
Every Amazon unit, accounted for.
SellerERP follows each unit from purchase to payout, so your margins, stock and claims finally add up.
One unit. Every stop on its journey.
Most tools count totals. SellerERP gives each unit an identity, so every number walks back to a real purchase.
Illustrative unit ITEM-3a101a3ba0-0005. Every stop is a row in the ledger, with its source and its cost.
The clarity Seller Central never gave you.
Know what Amazon owes you
Removals, vendor receipts, cases and reimbursements are chained per unit, so unclaimed money has a name and a number.
Every unit has an ID
Assigned at purchase, then followed through every receipt, transfer and return.
A real COGS engine
FIFO per fulfillment center or weighted average. Cost travels with the unit.
Reconciliation, not estimation
Unlogged shipments, wrong MSKUs, over-receipts and vanished units show up as exceptions you can act on, never averaged away.
Purchase planning
Reorders from sell-through, lead times and inbound delays. Fewer stockouts, less cash stuck on shelves.
Optional private hosting
Prefer to keep it in-house? You can.
For sellers who want full control of their margins and supplier prices, SellerERP can also run as a private install on infrastructure you choose.
Your servers or your cloud
Kubernetes on your own hardware or a cloud account you choose.
Your own Amazon connection
The API client and credentials are registered to you. No aggregator in between.
One customer, one install
Raw reports in your PostgreSQL, insights in your DuckDB store.
A developer you can call
The person who built it sets it up with you and adapts it to your files.

Sound familiar?
The numbers you need are buried across Seller Central.
Customer returns quietly eat into your margin.
Units go missing and nobody can say where.
Reimbursements you were owed slip past the deadline.
Bestsellers run out right before the busy week.
Cash sits in slow stock instead of working.
SellerERP fixes all of this.
Built for Amazon FBA brands with large SKU ranges, fast-moving goods, complex landed costs and tight cash cycles.
Private install, step by step.
If you choose to host it yourself, this is how we set it up together. History loads in the background while live updates already flow in.
Register privately
A developer registration and Selling Partner API client are created under your account.
Deploy the gateway
It runs in your cluster and paces every call to Amazon's rate limits.
Fetch your history
Past reports load in the background, so dashboards start full, not empty.
Subscribe to live updates
Notifications start arriving while the backfill is still running.
Store raw reports
Everything Amazon sends is kept as received in your PostgreSQL.
Turn data into insight
ETL workers match, reconcile and cost it, then write to DuckDB.

Questions
Before you ask.
Where does my data live?
That is your choice. Describe the standard hosting setup here. If you prefer, SellerERP runs as a private install: the Amazon API client is registered in your name, raw reports sit in your PostgreSQL and insights in your DuckDB store.
What data does it need?
Amazon data comes straight from Amazon through your own API client: history first, then live updates. You add your purchase register for costs. Anything that doesn't match becomes an exception, not a guess.
Will it fit my setup?
It is built for Amazon FBA brands selling across European marketplaces. The ETL is adapted to your purchase files and fulfillment model, and other setups can be scoped with the developer.
What do I need to host it myself?
A Kubernetes cluster for the gateway and ETL workers, PostgreSQL for raw reports, and space for the DuckDB store, on your server or in a secure cloud account. Add sizing and network requirements.
Who builds and maintains it?
The developer who built it. You work with that person directly on setup, custom reports, and changes as your business changes.
What does it cost?
Start with the demo and click through the modules. Add the pricing model, or say pricing is scoped per deployment.
