We built a WhatsApp commerce and communication platform over 8 weeks: (1) Order Communication Automation -- integrated with the brand's Shopify Plus store and PostNL shipping: customers who opted in during checkout received the complete order lifecycle via WhatsApp -- order confirmation with product images, payment confirmation, shipping notification with tracking link, out-for-delivery alert with live delivery window, delivery confirmation with one-tap satisfaction rating, and return instructions if needed. The opt-in rate during checkout was 72% (customers chose WhatsApp over email for order updates). (2) Delivery Interaction -- when PostNL provided a delivery window, customers received a WhatsApp message allowing them to confirm the window, request a different time, provide delivery instructions (leave with neighbour, place in delivery box), or redirect to a PostNL pickup point -- all within the WhatsApp conversation.
Failed delivery notifications were sent immediately with re-delivery scheduling options, eliminating the frustrating "we tried to deliver" cards that generate expensive customer service calls. (3) Customer Support -- the top 15 support question categories (return policy, warranty claims, product compatibility, order modifications, shipping status, account issues) were automated with AI-powered responses trained on 3 years of support ticket data. Complex inquiries were escalated to human agents with full context (customer order history, previous interactions, product information). The WhatsApp support channel operated 24/7 for automated responses and during business hours for agent escalation. (4) Cart Recovery -- abandoned carts triggered a WhatsApp message 2 hours after abandonment (for opted-in customers): a personalised message showing the abandoned product with image, current price, stock availability, and a one-tap link to complete checkout. A second message 24 hours later offered a 5% discount code.
(5) Post-Purchase Engagement -- satisfied customers (those who rated their delivery experience positively) received product tips and accessories recommendations 7 days after delivery, review requests 14 days after delivery, and replenishment reminders based on product lifecycle (e.g., replacement accessories). (6) GDPR-Compliant Consent -- opt-in was granular: customers chose which WhatsApp communication categories they wanted (transactional updates, support, marketing). Opt-out was available at any time via a simple WhatsApp reply. Consent records were stored in the Shopify customer profile and auditable for AP compliance.
