Expand your reach and connect with more customers

The Seller Community is a central directory inside the Marketplacer platform where operators explore new brands, categories, and suppliers. These operators collectively attract 2 billion visitors annually and generate over $35 billion in yearly e-commerce sales.

Why Join the Seller Community?

Joining the Seller Community helps sellers reach new retail and loyalty marketplaces without adding complexity to their operations.

More eyes on your brand

Retailers search the Seller Community by category, brand, region, and fulfillment capabilities — giving your products visibility to operators actively looking to onboard new sellers.

When an operator sees a fit, they invite you directly. There’s no lengthy application process or pitch required.

You don’t need new systems or complicated setup. Connect your catalog once through your preferred method and keep managing products, pricing, and stock the same way you do today.

The Seller Community gives you a low-friction entry point into multi-marketplace selling. Start simple, learn the model, and expand at your own pace — with the option to apply to Curator when you’re ready for more visibility.

From Application to Live Sales — Fast

 Joining Curator is simple. We handle the complexity so you can focus on selling.

Step 1: Apply & Create Your Profile

Set up your business details, categories, and regions served so operators understand who you are and what you offer.

Step 2: Operators Discover You

Retailers browse the directory for new brands and categories. When your catalog aligns with their strategy, they’ll reach out.

Step 3: Review Invitations & Go Live

If an operator wants to work with you, you’ll receive an invitation directly through the platform. You stay in control of who you partner with.

Step 4: Connect Your Catalog

Once you accept an invitation, sync your products using your ecommerce integration, API, or CSV/XML — whichever fits your workflow.

Step 5: Fulfill Orders

After onboarding with the operator, your products go live. Orders flow into your existing systems so you can fulfill and grow with ease.

Fast & Easy Integration

Marketplacer fits around how you already work. Sellers can connect their products using:

  • MConnect (ecommerce integrations)
  • API integration
  • CSV/XML uploads
  • Channel Managers

No rebuilds. No new systems. Just a fast connection that keeps your products synced and ready for operator review.

Frequently Asked Questions

For more questions, contact us.

Do I need to meet any requirements to join?

No, Seller Community itself is open and accessible. If you’re a legitimate seller able to fulfill orders, you can join, but Operators may have their own criteria when evaluating sellers.

Operators browse the directory by product category, brand, region, and fulfillment capability. If your products align with what they’re looking for, they can send you an invitation directly through the platform. You don’t need to pitch or apply — your profile serves as your introduction.

Joining the Seller Community makes your business discoverable, but you only begin selling once an operator onboards you into their marketplace.

No. We have different methods for Sellers to connect to the Marketplacer platform.

  • MConnect – supports sellers using Shopify, BigCommerce, WooCommerce, Adobe Commerce (Magento 2), or commercetools.
  • API integration – For sellers using platforms not supported by MConnect.
  • Direct file upload (CSV/XML) – Perfect for bulk uploads or sellers without an integrated storefront.

There’s no cost to appear in the Seller Community. Commercial arrangements such as commissions or fees vary by operator and are shared transparently when you’re invited to join their marketplace.

When you accept an invitation, you’ll complete onboarding with that operator, connect your products to their marketplace, and then your items can go live. After that, orders flow through Marketplacer and into your fulfillment workflow.
