SaaS revenue recognition and KPI tracking have traditionally been managed manually in Excel—complex, data-intensive processes dependent on thousands of formulas that are error-prone and fail to scale. My solution leverages ChatGPT and Claude as AI coding assistants to completely automate this workflow using Power Query (M-code). The AI assistants guided every stage: establishing API connectivity with our ERP system (Zoho Books), translating plain-English business rules into functional code, building data transformation logic, and systematically debugging errors. The most remarkable aspect was how a single working code—such as an ARR waterfall report—could be instantly adapted into entirely different outputs like customer count analysis through simple conversational prompts, demonstrating how AI bridges the gap between business logic and technical implementation for finance professionals without extensive coding backgrounds.

The impact has been substantial and measurable. What previously consumed 50-60+ hours annually in manual reconciliation now operates automatically with minimal intervention. Month-end close timelines compressed from 3 days to approximately 3 minutes for revenue recognition outputs. Beyond time savings, the solution delivers real-time business intelligence through always-on dashboards providing immediate visibility into ARR movements, customer metrics, and deferred revenue positions—enabling faster, data-driven decision-making. This approach demonstrates how finance professionals can harness AI tools as collaborative coding partners that democratize automation and transform operational efficiency.
