Seller onboarding and split orders

Sellers need onboarding, listing management, and distinct order permissions. Splitting orders, fees, and payouts creates reconciliation work that a single merchant store avoids.

Who handles disputes and seller verification

The operator needs rules and people for disputes, prohibited items, and seller checks. Payment-provider fees and marketplace legal requirements are outside development labor.

A cheaper way to start with Superapp

Build a focused version yourself before commissioning a full custom project. Superapp Pro is $25 a month; the subscription covers its plan allowance, while your time, extra usage, integrations, hosting, and specialist work remain part of the budget. A Superapp site is an alternative implementation, not a guarantee of WordPress or Shopify compatibility.

Sources and methodology

Rates are global marketplace benchmarks, not US-only agency quotes. Freelancer and agency ranges overlap because they describe different samples. WordPress.com Personal and Shopify Basic use annual billing, exclude introductory promotions and taxes, and replace the hosting budget. Feature hours and recurring budgets are our explicit planning assumptions.
