# Fishbowl: Empty class value in QuickBooks sync

> Fishbowl tried to sync data to QuickBooks but a required Class field was blank.

## What it means
Fishbowl is trying to create or update a record in QuickBooks, but the Class field (used to classify and organize transactions) is blank. QuickBooks requires a value here, so the sync cannot complete.

## What to check
- Verify that classification or category fields in your Fishbowl record are filled in, not blank
- Review your QB sync configuration to see which Fishbowl field maps to the QB Class
- Make sure all required fields are completed in your Fishbowl record before syncing
