Why Your Products Keep Going Out of Stock on Marketplaces (And How to Fix It)

TL;DR

• Overselling happens when stock levels aren’t synced fast enough across your sales channels.
• A single out-of-stock incident on bol.com or Amazon can result in account warnings, lost Buy Box position, and cancelled orders.
• Manual stock management breaks down once you sell on 2 or more channels simultaneously.
• Automated inventory sync updating every 5 to 15 minutes is the only reliable way to prevent overselling at scale.
• Tools like Koongo synchronise your stock across 500+ channels automatically, with no manual work required.
