Automated Challan Management System Development

Hello, I need a complete automated challan management system for my legal/business work. My requirements: Extract challan details automatically from uploaded PDF files using OCR/AI. Store extracted data in Google Sheets. Compare Bill and Urgent sheets using Challan Number. Urgent sheet: Column C = Challan Number, Column G = Status. Bill sheet: Column G = Challan Number, Column K = Settlement Amount. Identify matching challans where Urgent status is "clear" and Bill settlement amount is ₹0. Automatically highlight only the relevant Challan Number cells in Bill Column G. Detect duplicate challans, missing records and OCR errors. Process new PDFs daily with minimum manual work. Provide a simple dashboard and error report. I do not want to manually operate complicated formulas or scripts. Please first review a sample of my actual files and demonstrate a working prototype with 50–100 records. I will pay for a complete, reliable solution after testing.
