Inspiration

Managing business finances often involves repetitive tasks such as creating invoices, tracking overdue payments, processing contractor payouts, and maintaining financial records. These activities consume valuable time and require switching between multiple platforms. We wanted to simplify these operations by combining AI-powered intelligence with PayPal's payment infrastructure, creating a platform where businesses can manage financial tasks through simple natural-language instructions.

What it does

PayPilot AI is an AI-powered financial operations copilot that converts natural-language instructions into structured and secure payment actions. Its key capabilities include: AI Payment Agent: Understands user instructions and prepares invoices and contractor payouts. Automated Workflows: Triggers financial actions based on events such as invoice payments, overdue invoices, and approved tasks. Financial Copilot: Answers questions about transactions, outstanding invoices, and recorded financial data. PayPal Integration: Connects with PayPal Sandbox APIs for checkout and contractor disbursements. Financial Safety: Implements human approval, duplicate transaction prevention, and audit-backed recordkeeping.

How we built it

We developed PayPilot AI using a modern full-stack architecture: Frontend: React 19, TypeScript, Vite, and Tailwind CSS for an interactive financial dashboard. Backend: Python, FastAPI, and Pydantic for API development, request validation, and business logic. AI Integration: Google Gemini 2.5 Flash for natural-language understanding, entity extraction, and structured action planning. Payment Integration: Official PayPal Developer REST APIs using OAuth 2.0, Orders API, and Payouts API. Database: SQLite and SQLAlchemy for invoices, transactions, payouts, and audit records. Testing: Pytest for validating payment safeguards, business rules, and application workflows. We also implemented a deterministic fallback engine to support basic natural-language processing when the Gemini API is unavailable.

Challenges we ran into

Some of the major challenges included: Converting flexible natural-language instructions into accurate and structured financial actions. Integrating PayPal Sandbox authentication, order creation, payment capture, and payout operations. Preventing duplicate transactions and ensuring reliable payment processing. Designing human approval mechanisms for sensitive financial operations. Keeping AI-generated financial responses grounded in actual database records. Coordinating multiple backend services while maintaining consistent transaction and audit records.

Accomplishments that we're proud of

Built an integrated AI-powered financial operations platform combining natural-language processing with PayPal payment APIs. Implemented approval-gated invoice and contractor payout operations. Developed conditional workflows for invoice payments, overdue reminders, and contractor payouts. Established duplicate detection and an audit-backed financial ledger. Created a database-grounded financial copilot to provide reliable business insights. Achieved 9/9 passing backend tests covering validation, approval controls, duplicate detection, AI fallback, and workflow execution.

What we learned

Through this project, we gained practical experience in: Building AI agents that convert natural-language instructions into structured actions. Integrating external payment APIs and managing OAuth 2.0 authentication. Designing secure financial workflows with human-in-the-loop authorization. Implementing database persistence, transaction reconciliation, and audit logging. Developing reliable full-stack applications using React and FastAPI. Understanding the importance of validation, idempotency, and responsible AI in financial applications.
