PostBooks vs. G-Accon: Payroll Import for QuickBooks & Xero
G-Accon is a Google Sheets add-on that syncs data between Google Sheets and QuickBooks Online or Xero. It's a flexible tool for accountants who already manage data in spreadsheets and want to push that data into their accounting software. PostBooks takes a different approach: it automates the entire payroll-to-journal-entry workflow directly from the payroll provider's CSV, without requiring a spreadsheet intermediary.
How G-Accon works for payroll journal entries
With G-Accon, you would: export your payroll report from your provider (Gusto, ADP, etc.), copy the relevant figures into a structured Google Sheet, map the columns to QBO or Xero fields using G-Accon's configuration, and then push the data to your accounting software. G-Accon handles the API connection and import — but the spreadsheet preparation, column mapping, and data validation are still manual steps. For bookkeepers managing multiple payroll clients across different providers, maintaining separate Google Sheets templates for each client adds up quickly.
How PostBooks works for payroll journal entries
PostBooks skips the spreadsheet entirely. Upload the raw payroll CSV from Gusto, ADP, Paychex, or 15+ other providers, review the auto-mapped account assignments (saved per client), and export a balanced journal entry directly to QBO, Xero, or QB Desktop IIF. No spreadsheet preparation, no column configuration, no intermediate steps. The first run for a new client takes about 10 minutes to set up the account mapping; subsequent runs take under 60 seconds.

G-Accon is a solid choice if you already manage client data in Google Sheets and need a reliable bridge to QBO or Xero. PostBooks is the better choice if you want to eliminate the spreadsheet step entirely and go directly from payroll CSV to posted journal entry.
