From WhatsApp Message to Xero Invoice: How Tradestack Actually Ships AI Agents

Tradestack overcame the common hurdle of authentication that prevents 70% of AI projects from reaching production by leveraging Arcade.dev's capabilities to build an AI-driven back office for UK contractors. Facing the challenge of providing AI with secure access to critical business systems, Tradestack needed an agent capable of executing tasks like creating estimates, sending invoices via Xero, and managing communications through Outlook and Gmail with enterprise-grade security. Despite the market's lack of expertise in AI, identity systems, and distributed infrastructure, the recommendation from Harrison Chase at LangChain led Tradestack to Arcade.dev, which offered a clean OAuth implementation and control over tool design. This partnership enabled Tradestack to quickly deploy toolkits for Outlook and Xero, emphasizing the importance of clean OAuth for customer trust and focusing on high-quality integrations rather than sheer quantity. Tradestack's approach also incorporated human-in-the-loop processes for high-stakes actions, enhancing the reliability of its AI assistant in managing tasks through WhatsApp and email. By addressing authentication and infrastructure challenges, Tradestack is now positioned to enhance customer intelligence, focusing on context, long-term memory, and scalable evaluation, while avoiding the pitfalls of rebuilding authentication infrastructure.
