Marketplace Stack

A marketplace stack is a software architecture designed to connect multiple buyers and sellers through a shared transactional platform. Unlike traditional ecommerce systems where a single business sells its own products or services, marketplaces coordinate transactions between many independent participants within the same ecosystem.

Marketplace architectures power product marketplaces, freelance platforms, booking services, rental platforms, digital asset exchanges, delivery networks, creator platforms, peer-to-peer marketplaces, and business-to-business trading systems. The primary goal is to facilitate discovery, build trust, coordinate transactions, and manage financial and operational workflows across a multi-sided ecosystem.
