Multi-Marketplace Stock Management: Keeping Trendyol, Hepsiburada & Shopify in Sync

Challenges of Multi-Channel Stock Management

The biggest risk for multi-marketplace sellers: selling products you don't have. If a product sold on Trendyol doesn't update on Hepsiburada, you face customer loss and penalties.

Stock Sync Strategies

• Central stock pool — All channels fed from a single stock source.

• Safety stock — Reserve stock per channel. 10-15% buffer per channel.

• Instant updates — Update stock across all channels the moment a sale happens.

• Automatic reorder — Automatic supplier orders for products below a set level.

Result

Our clients see an average 94% reduction in stock errors after sync implementation.
