Sellerside helps you manage
Purchase orders
Buy the right quantity, at the right cost - every PO sized against real margin and lead times.
Inventory
Stock decisions tied to real margin, not warehouse guesswork - across every marketplace.
P&L
Reconciled financials - orders, fees, ads, refunds - updated daily.
Forecast
AI-powered demand forecasting that protects cash and avoids storage fees.
Turn stockouts into a P&L line you control
Every unit at risk of stockout or overstock is translated into euros - lost margin, tied-up cash, or avoidable FBA storage fees - before it happens, not after your finance team finds it in the numbers.


From reorder point to reconciled margin
Purchasing decisions, lead times and landed costs feed straight into your P&L - so every PO you place is sized against real contribution margin, not a spreadsheet guess.
