How to create a Chase positive pay file
Export your check register from QuickBooks, your ERP, or a spreadsheet, then use the free generator: upload the file, match your columns once, choose “Chase Business Online / Chase Connect (CSV)”, and download a file formatted exactly as above. Processing happens entirely in your browser, so account and check data never leaves your computer. Always verify your first file with a test upload in your bank portal.
