Marketplace Builder Stack
Complete a transaction between two distinct parties.
Work backward from the outcome
Complete a transaction between two distinct parties
1. Prepare a realistic example
Model a buyer and a seller separately. Define listing approval, payment ownership, fulfillment, disputes and the point at which each party is notified.
2. Define the handoffs
Use stable IDs for listing, order and both parties. Keep marketplace permissions and financial state separate from public profile data.
3. Rehearse the exceptions
Test a rejected listing, failed payment, partial fulfillment, dispute and duplicate notification using test records. Verify one seller cannot access another’s private data.
4. Budget and keep an exit
Budget for payment processing, payouts, disputes, support, identity requirements and database/storage usage.
Export transaction relationships and an audit trail. A rollback must preserve money movement and fulfillment state, not merely restore the website.
