How to choose a marketplace platform: the features that matter

To choose a marketplace platform, start from your operating model — third-party marketplace, dropship or both, B2C or B2B — and whether you keep your current storefront; then check five capabilities (seller onboarding, catalogue management, order management, commissions, split payments), the integrations with your stack, the vendor’s security certifications and customer references, and the three-year total cost. Ask every vendor to demonstrate your own workflows, not a generic demo.

1. The five core capabilities

These are the jobs a marketplace operator does every day. Our ranking checks whether each vendor states them on its own pages:

Capability	What to check
Seller onboarding	Self-service sign-up, identity checks (KYC), contract acceptance, seller portal
Catalogue management	Bulk imports, attribute mapping, validation and moderation rules
Order management	Split orders across sellers, tracking, returns, cancellations
Commission management	Rules by category and seller, invoicing to sellers
Split payments and payouts	Who collects the money, who pays sellers, on which schedule

A capability a vendor does not document publicly is shown as “not stated” in our pages: ask about it directly.

2. Integrations

List the systems the marketplace must talk to — storefront, ERP, product information management, order management, payment provider, tax engine — and check which ones each vendor names. 35 of the 43 platforms state a headless API, which matters if your storefront is custom.

3. Business models

Check that the platform supports every model you plan to run in the next three years: B2C, B2B, dropship, services or digital products. Switching platform later is expensive.

4. AI, retail media and growth features

Vendors increasingly differentiate on AI (catalogue enrichment, seller onboarding, moderation, search, agentic commerce) and on retail media, the advertising sellers buy on your site. 11 platforms in our ranking state retail media.

5. Trust: certifications and references

Ask for ISO 27001 and SOC 2 reports, and for references in your sector and country. A vendor that names large customers on its own site is easier to check.

6. Total cost
