A fast-growing UK D2C e-commerce brand was drowning in repetitive support queries. Within 6 weeks, an AI chatbot was handling 73% of all tickets — with faster responses, higher CSAT, and zero temp hires needed for peak season.
When the Head of Customer Experience at a UK D2C e-commerce brand (fashion and homeware, £8M revenue, 45,000 orders per year) reached out to Digital by Default, the frustration was palpable:
The business was caught in a vicious cycle: ticket volume was growing faster than the team could handle, and every slow response was eroding customer loyalty.
Before recommending any solution, we conducted a deep-dive analysis of the client's ticket data, support workflows, and customer journey:
We designed and deployed a production-grade AI chatbot system using best-in-class components, fully integrated with the client's Shopify store and existing support infrastructure:
| Layer | Technology | Role |
|---|---|---|
| Orchestration | Intercom Fin AI | Conversation management, intent classification, seamless handover to human agents |
| LLM Backend | GPT-4o (via Azure) | Natural language understanding, context-aware responses, brand tone matching |
| Knowledge Base | RAG (Pinecone + custom embeddings) | Product catalogue, returns policy, sizing guides, shipping info — synced daily from Shopify |
| Integration | Shopify API + Royal Mail API | Real-time order status, tracking numbers, returns portal deep links |
| Workflow | n8n (self-hosted) | Escalation routing, CSAT surveys, weekly analytics reports, Slack alerts |
| Analytics | Custom dashboard | Resolution rates, CSAT by topic, escalation patterns, response times |
We evaluated four leading platforms against the client's specific requirements. Here's a summary of our recommendation rationale:
| Platform | Strengths | Verdict |
|---|---|---|
| Intercom Fin | Native Shopify integration, excellent tone control, proven at scale | Selected |
| Zendesk AI | Strong AI features, robust ticketing; heavier enterprise setup required | Shortlisted |
| Tidio AI | Good for SMBs, easy setup; less customisable for complex workflows | Considered |
| ChatGPT wrapper | Fast to prototype; no native integrations, escalation, or analytics | Considered |
Analysed 6,200 past tickets, built RAG knowledge base from product pages, policy documents, and FAQ content. Defined tone of voice guidelines to match the brand's warm, casual style.
Built 10 core conversation flows, connected Shopify order API, Royal Mail tracking, and returns portal. Trained on 500 example conversations covering all major intent categories.
400+ test conversations across all intents. A/B tested AI vs human responses — AI scored higher on speed, equal on accuracy. Edge cases identified and escalation paths validated.
Days 1–3: AI handled sizing and delivery queries only. Days 4–7: full deployment across all channels — website widget, email, and Instagram DM.
Customers who previously churned due to slow responses now get instant answers. Repeat purchase rate for AI-served customers is 28% higher than the previous 14-hour wait cohort. The chatbot doesn't just resolve tickets — it protects revenue.
Black Friday 2025 generated 340% of normal ticket volume — handled entirely by the AI with zero temp hires. The entire seasonal surge was absorbed without a single additional headcount or a drop in response quality.
Human agents now handle only complex cases requiring empathy and judgment. The team reduced from 4 to 2 FTEs on support (other 2 redeployed to CX strategy and retention). Agent satisfaction rose from 5.8 to 8.7 out of 10.
The AI maintains the brand's warm, casual tone across every interaction — day and night, weekday and weekend. No more variance between agents, no more tired 11pm replies that don't match the brand. Every customer gets the same quality.
Following the success of the Tier-1 ticket automation, the client expanded the AI chatbot into proactive customer engagement. The system now:
Digital by Default provides monthly optimisation reviews: analysing conversation transcripts, tuning intent models, updating the knowledge base as new products launch, and A/B testing conversation flows. The AI gets measurably better every month. Resolution rate has climbed from 73% at launch to 78% at the 6-month mark.
