OnPay Payroll to QuickBooks Desktop: IIF Journal Entry Guide
OnPay doesn't have a native journal entry integration with QuickBooks Desktop. QuickBooks Desktop uses a proprietary IIF (Intuit Interchange Format) file for journal entry imports, and OnPay doesn't produce this format. Bookkeepers must either enter the journal entry manually or convert the OnPay report themselves.
How PostBooks connects OnPay to QuickBooks Desktop
- Export the OnPay payroll report. Download the payroll summary or journal entry report from OnPay as a CSV file.
- Upload to PostBooks and map accounts. PostBooks maps OnPay line items to your QuickBooks Desktop chart of accounts. Configure the mapping once and PostBooks applies it every pay run.
- Export as IIF file. PostBooks generates a valid IIF file you can import directly into QuickBooks Desktop via File > Utilities > Import > IIF Files.
