Vendor Procurement AI Agent

phData delivered an Agentic AI-powered automation solution in just six weeks, leveraging a powerful combination of Amazon Nova-Act for intelligent action generation and PlaywrightMCP for robust browser automation. This dual-tool approach provided the foundation to successfully navigate the end-to-end procurement processes for all seven vendors. The core of the system is a Fine-Tuned Nova LLM that acts as the intelligent "brain" for the operation. To navigate the vendors' sites, the system mapped each process into “golden paths,” which are stored as Vendor Agent Plans. These plans provide the AI agent with proven strategies for executing the correct login, cart management, checkout, and payment steps. To ensure accuracy and prevent errors, every instruction generated by the LLM is first checked by an Action Validation module before execution. If an action is invalid, an immediate feedback loop prompts the LLM to self-correct and generate a new action. For complex scenarios with low confidence, like a CAPTCHA, the system intelligently triggers a Handoff to Human, ensuring process continuity. The solution is engineered to become smarter over time. A Nightly Review of Golden Paths analyzes successful runs to refine the agent's strategies, while performance data is collected to continuously fine-tune the core LLM itself. The entire application is containerized in an ECS Pod for scalability, and comprehensive Action Logging provides full visibility for auditing and analysis.
