Two-Sided Marketplace Architecture
The core engine of your platform — buyer and seller (or provider/client) roles, listing and discovery flows, and the transaction logic that connects both sides.
Multi-role user system
Buyer and seller (or provider and client) accounts with separate onboarding, profiles, and dashboards — so each side of the marketplace only sees what they need to transact.
Listing/booking/search flows
The paths that put supply in front of demand: listings, discovery, search, and booking or purchase — designed around how your two sides actually meet.
Transaction state management
The lifecycle from request to complete — accepted, in progress, delivered, paid — so both sides always know where a deal stands.
Real-time notifications
In-app and email alerts when a listing is booked, a payment clears, or a status changes — so neither side is waiting on a refresh.
