Marketplace Integration: Manage Trendyol, Hepsiburada and N11 Alongside Your Website from One Panel

I develop integrations that push your products to marketplaces, update stock and prices from a single source and pull marketplace orders into your website's admin panel.

Quick answerMarketplace integration is the automatic API-based synchronization of product, stock, price and order data between your ecommerce site or stock software and marketplaces such as Trendyol, Hepsiburada and N11. Hakan Sevimoğlu has developed the MobilyaPro B2B system with Trendyol, Hepsiburada and N11 integration, as well as marketplace-integrated ecommerce software.

What does marketplace integration do?

  1. Product sync: sending products to the marketplace with category and attribute mapping
  2. Shared stock: a product sold on one channel is deducted from stock on all channels
  3. Pricing rules: marketplace-specific prices and commission markups
  4. Order import: marketplace orders land in your website's panel
  5. Shipping and invoicing: tracking numbers and invoice data sent to the marketplace
  6. Reporting: sales and profitability by channel

Why a custom integration?

Off-the-shelf integrators come with monthly fees and product/order limits; with a custom integration you work directly and without limits with your own stock software, ERP or website, and the rules are written around your business. Unlike off-the-shelf ecommerce packages, custom software has no sales commission or per-user monthly license; the source code and customer data belong to you.

To manage all channels: ecommerce management; for shipments: shipping integration.
