Agentic Commerce Outcomes & Success Stories

Fashion Retailer

+34% Conversion from Agent-Driven Sessions

A mid-market fashion brand was losing product discovery share to ChatGPT and Perplexity. Shoppers were asking AI agents for outfit recommendations and never visiting the brand's site. We built a proprietary AI shopping agent embedded across their site and app, with full integration into Google Gemini shopping. Within 90 days, agent-driven sessions outperformed traditional search traffic by 34% on conversion rate, and AOV increased by 18% as the agent surfaced complementary product bundles.

FREQUENTLY ASKED QUESTIONS

Get Every Query Answered About Agentic eCommerce

Get Every Query Answered About Agentic eCommerce

What exactly is agentic eCommerce?
+
Agentic eCommerce refers to AI agents that autonomously handle the entire shopping journey on a customer's behalf from research and product discovery to comparison, cart building, and checkout with minimal human input. Unlike traditional chatbots that answer questions, AI shopping agents take action like browsing catalogs, and completing purchases based on the intent.
Why does my brand need to have its own AI shopping agents now?
+
1 in 5 Cyber Week 2025 orders involved an AI agent (roughly $70 billion in GMV). Several top platforms like OpenAI, Google, Perplexity, and Amazon have all launched agentic shopping tools in the past 12 months.
How soon can implementing an agent improve my business outcomes?
+
Initial AI readiness improvements (structured data, schema optimization, feed setup) typically go live within 3–4 weeks and begin generating agent-discoverable traffic immediately. Custom AI shopping agent builds typically deploy within 8–12 weeks. Most businesses can witness an increase in revenue within 90 days of deployment.
Is agentic commerce secure? How do you prevent fraud?
+
Security is a core part of every deployment. With ~80% of financial institutions expecting fraud to increase via agentic commerce (Accenture), we build multi-layer authentication, transaction verification, and fraud detection into every agent build. We implement secure payment practices using trusted partners like Stripe, PayPal, Shop Pay. We also follow zero-trust policy for all agent-to-merchant API communications.
Do I need to rebuild my eCommerce platform to go agentic?
+
No. We implement AI agents to your existing tech stack including Shopify, Magento, WooCommerce, BigCommerce, Salesforce Commerce Cloud, and more. Agentic commerce is typically layered on top of your existing infrastructure through API integrations.
What does an AI Readiness Audit include?
+
Our audit assesses: (1) Product data completeness and schema markup quality (2) AI agent crawlability and indexing (3) Commerce API endpoints and agentic transaction readiness (4) Competitor AI visibility benchmarking (5) Platform-specific gaps across OpenAI, Google, Perplexity, and Amazon ecosystems
Do you build eCommerce platforms from scratch?
+
Yes. We build full eCommerce platforms from scratch, including custom-coded storefronts, headless commerce platforms, Shopify, Magento, WooCommerce, BigCommerce, and many other platforms. Every eCommerce platform we build is designed to be AI-ready from day one, including clean product data structure, schema markup, and commerce APIs that make the store instantly compatible with AI shopping agents.
At DF24, do you offer ongoing eCommerce site maintenance?
+
Absolutely. This is a big part of what we do. We offer dedicated maintenance retainers which include 24/7 uptime monitoring, performance optimization, security patching, plugin and integration updates, bug fixing, and platform version updates. Whether your store runs on Shopify, Magento, WooCommerce, or a bespoke build, our team will handle the end-to-end of your ecommerce technology.
