Planning an e-commerce website for real operations

Define your source of truth

Decide which system owns product, price and stock data. Model variants and availability clearly. Multi-channel selling needs synchronisation and a way to handle disagreements.

Design the complete order journey

Show delivery costs before confirmation. Handle failed and duplicate payments, refunds and cancellations. A success-page visit alone is not proof of payment.

Make operations maintainable

Provide order and customer-contact tools with role-appropriate access. Measure completed orders and abandonment without sending payment details or personal data to analytics.
