Billy is an AI tool developed by Stampli to facilitate and automate aspects of the procurement to payment (P2P) process. It is designed to understand and adapt to your organization's specific P2P process, rather than simply automating individual steps.

Stampli's Billy the Bot is an AI assistant embedded in the Stampli accounts payable automation platform, designed to learn each organization's unique AP processes, vendor relationships, and approval workflows and apply that knowledge to process invoices with increasing autonomy and accuracy over time.
Unlike generic AP automation that requires extensive template configuration, Billy learns from the way a specific organization handles its invoices, becoming more effective the longer it works with a company's data.
Billy handles the cognitive work of invoice processing: identifying the right GL codes based on historical patterns, suggesting the appropriate approvers based on invoice type and amount, flagging invoices that deviate from expected patterns, and answering questions from AP team members about invoice status and processing history.
This combination of automation and intelligence reduces the manual decision-making burden on AP staff without removing human oversight from the process.
Stampli's AI approach reflects a broader philosophy about AP automation: rather than forcing organizations to adapt their processes to fit a rigid system, Billy adapts to how each organization actually works making the automation feel like an accelerator of existing expertise rather than a replacement for it.
For finance teams looking to improve AP efficiency without a disruptive reimplementation of their processes, Billy provides a learning-based path to automation that grows in capability over time.
