Add the Marketplace Engine. Keep Everything Else.

Marketplacer is composable commerce infrastructure. It connects to your existing frontend as the marketplace engine operating underneath.

  • Your storefront stays in place. Customers browse and purchase through the experience you've built. Third-party products appear within your assortment, under your brand.
  • Marketplacer handles the operational layer. Orders route automatically. Sellers fulfil directly. Tracking, refunds, and remittances managed within the platform — without touching your core systems.
  • Data flows in real time. Catalogue, pricing, inventory, and order data sync continuously via REST and GraphQL APIs and webhooks.

Custom & Legacy Stacks

Not on a prebuilt connector platform? Marketplacer's REST and GraphQL APIs and webhook architecture support custom integrations with bespoke, ERP-connected, or legacy commerce environments.

⸺ How it works

Connected. Composable. Ready for Your Stack.

Marketplacer operates as the marketplace layer within your existing commerce architecture. Three steps from connection to live revenue.

Connect your storefront

Prebuilt connectors for major platforms and an API-first architecture mean your dev team connects Marketplacer to your existing stack — not the other way around. No core system changes required.

Onboard sellers & catalogue

Sellers are onboarded into Marketplacer. Their products sync into your assortment automatically — presented under your brand, priced in your storefront, invisible to your customer as third-party.

Revenue flows automatically

Orders placed through your existing checkout route into Marketplacer. Sellers fulfil directly. Tracking, refunds, and remittances are managed automatically — commission revenue from day one of activation.

What flows through:

Product catalogue & inventory sync

Order routing & fulfilment

Shipment tracking & notifications

Refund & returns handling

Seller remittances

⸺ Get Started

Your Platform Is Ready. The Sellers Are Ready. Let's Talk.

The infrastructure exists — the question is how quickly it connects to your stack.

Frequently Asked Questions

Do we need to replace our existing eCommerce platform?

No. Marketplacer is designed to connect to your existing infrastructure, not replace it. Prebuilt connectors for major platforms and open REST/GraphQL APIs for custom stacks mean your platform remains in place — your brand experience stays yours.

You have 3 ways to find sellers:

  1. Seller Community: a directory of thousands of sellers you can access from your dashboard.
  2. Curator: a pre-vetted, pre-contracted seller network — Marketplacer manages onboarding and compliance; operators select from the shortlist based on your seller requirements.
  3. SRM: – contracted service for managing sellers as an ongoing operational function. Marketplacer handles everything from sourcing to management.

Marketplacer’s REST and GraphQL APIs support integration with any commerce environment, including bespoke and legacy stacks. iPaaS compatibility also enables connections across ERP, finance, and CRM ecosystems.

Marketplacer works with a global network of certified implementation partners — regional and global SIs who can lead the technical delivery. Most operators do not need to run implementation internally. Marketplacer’s own team provides support throughout.
