Gusto Payroll to QuickBooks Desktop: IIF Journal Entry Guide

QuickBooks Desktop uses a proprietary IIF (Intuit Interchange Format) file for journal entry imports. Gusto doesn't export IIF files. If you use Gusto for payroll and QuickBooks Desktop for accounting, you need to either enter the journal entry manually or convert the Gusto report to IIF format.

How PostBooks connects Gusto to QuickBooks Desktop

  1. Download your Gusto payroll report. Export the payroll summary CSV from Gusto.
  2. Upload to PostBooks and map accounts. PostBooks maps Gusto line items to your QuickBooks Desktop chart of accounts.
  3. Export as IIF file. PostBooks generates a valid IIF file you can import directly into QuickBooks Desktop via File > Utilities > Import > IIF Files.
