Third-Party Seller Onboarding and Marketplace Platform

Third-Party Seller Onboarding and Marketplace Platform

Challenge

Preventing duplicate listings and counterfeit risk while keeping onboarding friction low. We combined catalog matching, document checks and staged listing limits for new sellers.

Approach

We built a seller portal with KYC and business verification, bulk listing tools, catalog matching to existing products, and order and returns management. A commission and payout engine calculates fees, handles holds for disputes and produces settlement statements. Listing quality checks (images, prohibited items, price anomalies) run automatically before products go live. Seller performance scores drive search ranking and enforcement.

Outcome

Assortment expanded without additional inventory risk Illustratively ~2–3x faster seller onboarding compared to manual processes Automated, transparent payouts reduced seller disputes Quality checks kept prohibited and low-quality listings off the site New commission revenue stream on the existing platform
