eCommerce Marketplace Development Platforms

A marketplace lives or dies on seller operations, order splitting and payouts. We match the model to the platform, not the other way around.

Our default for enterprise marketplaces

The enterprise standard for large, complex marketplaces

  • Marketplace layer on multi-source plus custom development

  • Third-party catalog and per-seller offers

  • Mixed 1P and 3P carts with per-seller order routing

  • B2B workflows: company accounts, quotes, contract pricing

  • Hyvä or headless storefronts that stay fast at catalog scale

  • Best for large catalogs, B2B workflows and high GMV

What Is a Multi-Vendor eCommerce Marketplace?

The storefront is the easy part. A marketplace is an operations platform with a storefront on top.

  • One buyer order, split per seller automatically

  • Commission engine with per-category rules

  • Automated payouts sellers can trust

  • Self-service seller onboarding with KYC / KYB

  • Listing moderation and approval workflows

  • GMV and take-rate reporting

Liquidity comes first

No buyers without sellers, no sellers without buyers. Fast seller onboarding drives early growth.

Trust is the product

Buyers buy from the marketplace, not the seller. Moderation, ratings and reliable payouts.

Money flow is the hard part

Split payments, commissions and automated payouts. Manual reconciliation breaks at volume.

Control keeps quality up

Approval workflows for every listing and price change, so quality holds at scale.

B2B, B2C & Multi-Vendor Marketplace Development

B2C, B2B, dropship or hybrid, the operational rules change, and so does the build. We’ve mapped what each one takes, and we can build it on the platforms we know deeply.

B2C marketplace

One consumer checkout across many sellers. We can build the storefront and the operations behind it.

  • Fast seller onboarding:

    Self-service registration we can wire to KYC and moderation

  • Unified checkout

    One cart, one payment, split behind the scenes

  • Cross-seller merchandising

    Promotions and bundles that span sellers

  • Trust signals

    Reviews, ratings and seller scores buyers rely on

Buy-box competition

Cross-seller promotions

Mirakl Marketplace Integration for Adobe Commerce & Shopify

Already set on Mirakl? We connect it to the platform you run.

Mirakl handles third-party sellers, catalog, offers, orders and payouts; it sits behind your storefront, and we make the two work as one.

Whether you’re on Magento or Shopify, we bolt on Mirakl’s marketplace engine rather than rebuilding one from scratch.

Adobe Commerce

Mirakl + Adobe Commerce

Third-party catalog and offers, mixed 1P and 3P carts, per-seller order routing and payouts.

Shopify

Mirakl + Shopify / Shopify Plus

Add third-party assortment and marketplace operations alongside your catalog, on themes or headless.

The rest of the stack

We wire Mirakl into payments, PIM, ERP, OMS and search so sellers, offers, orders and money stay in sync.

AI for marketplaces, without ripping out your stack

A middle layer over your marketplace data. Nothing replaced, nothing rebuilt.

1

Connect to what you run

Your storefront, seller data, orders, payouts and catalog, wherever they live.

2

Build the MCP-native middle layer

AI that reads and acts on live marketplace data, with permissions and logging.

3

Make it do what you want

From seller onboarding to catalog enrichment to support that resolves itself.

What AI can do, grounded in your data

Magebit AI

Where’s my payout for last week, and why is one of my orders on hold?

Thinking ...

  • Reads payout and order data from the systems you already run
  • Explains the commission and the dispute hold, with the source shown
  • Routes to a human when the case needs judgment

Your payout of $4,820 lands tomorrow. One order is on hold pending a dispute — I’ve flagged it to a specialist for review.

Magebit AI

A new seller uploaded 2,000 SKUs and half are missing attributes. Can we fix the feed?

Working …

  • Normalizes the feed and fills attribute gaps at scale
  • Drafts descriptions for review, never auto-published
  • Flags listings that need moderation before going live

Done — 1,940 SKUs normalized and enriched. 62 are flagged for moderation, descriptions drafted for your review.

Magebit AI

What’s missing from this seller’s application, and can we speed it up?

Working ...

  • Checks KYC and KYB documents against your requirements
  • Lists exactly what’s missing and requests it from the seller
  • Queues the application for a human decision

Only the tax form is missing — I’ve requested it from the seller. The application is queued for your approval.

Frequently asked questions

If you can’t find the answer you’re looking for, feel free to reach out to us. We’re here to help!

Depends on your catalog, model and budget. Mirakl gives you enterprise marketplace operations fast; a custom build fits unusual commission logic or deep ERP and PIM coupling. We connect Mirakl to Adobe Commerce or Shopify, or build composable with Stripe Connect or Adyen for Platforms, and we’ll tell you honestly which fits before any pitch.

One checkout, funds routed to each seller and your commission to you, via rails like Stripe Connect, Adyen for Platforms, Mangopay or Mollie. The real decisions are aggregated versus split routing, your merchant-of-record position, and seller KYC. We scope those in discovery because they drive compliance and cash flow.

Adobe Commerce for large catalogs, B2B workflows and complex operations; Shopify when you’re already there and want third-party assortment fast. Both can carry a marketplace layer: native capabilities, custom modules or a connector like Mirakl.

With a discovery, not a build: model and liquidity plan, commission and payout economics, operations audit, platform recommendation, then an MVP-first roadmap. You leave with a plan you could hand to any agency, even if it isn’t us.

The cost of a multi-vendor marketplace depends on the business model, number of seller types, integrations, payment and payout flows, catalog complexity, and the platform used. A marketplace built on Adobe Commerce, Shopify Plus, Mirakl, or a custom architecture can vary significantly in scope. We usually start with a discovery phase to define the marketplace model, required features, integrations, and a realistic implementation budget.

Marketplace development typically takes several months, depending on the complexity of the platform. A simpler marketplace can be launched faster, while enterprise projects involving seller onboarding, ERP or PIM integrations, complex commissions, split orders, payouts, and custom workflows require more time. Magebit starts by defining the marketplace architecture and launch scope so the project can be delivered in clear phases.

Most multi-vendor marketplaces require seller onboarding and management, vendor dashboards, product and catalog management, order splitting, commissions, seller payouts, payment processing, shipping and fulfillment workflows, returns, reporting, and marketplace administration. B2B marketplaces may also require company accounts, contract pricing, RFQs, purchase orders, approval workflows, and ERP integrations.

Yes. Magebit can migrate existing marketplace platforms to Adobe Commerce, Shopify Plus, or another suitable architecture. Migration can include products, sellers, customers, orders, marketplace configuration, integrations, URLs, and SEO data. Before migration, we review the existing platform and marketplace logic to determine what should be migrated, rebuilt, integrated, or improved.

Yes. We integrate marketplaces with ERP, PIM, CRM, OMS, WMS, 3PL, payment, tax, shipping, identity, and other business systems. Marketplace integrations can also include seller systems, product feeds, EDI, Mirakl, and custom APIs. The architecture is designed around reliable data synchronization between the marketplace, sellers, and existing business systems.
