Let's team up to streamline your categorization process and ensure everything is organized just the way you need it, @GSPS.
If you're importing your bill from the Import data option, it’s important to note that automatic categorization isn’t available. You’ll need to manually assign each bill to your desired category. You can also add the appropriate category for your bills within the Account column of your CSV file before importing. To do so, here's how:
- Go to the Gear icon, then Import data.
- Select Bills.
- Once on the Import bills page, please download the sample file to map correctly your imported data.
- Open the downloaded file, then from the Account column, please add its correct category and ensure that the information you added is already existing in QBO to prevent any error messages.
- Save it and go back to your company file to upload your CSV file.
- Map your column heading properly, then click the Start import option.
