We need to verify the Comdata card you mean to link directly to QuickBooks, Burketanner.
 
To clarify further, are you attempting to link the Comdata card as a bank account, or is there a different functionality you’re trying to achieve? Please provide additional details so we can better assist you.
 
If you mean that the Comdata card is a bank, you can link it directly to QuickBooks. See this article for detailed steps: Connect a bank in QuickBooks Online.
 
If you’re referring to using the Comdata card for a different functionality, you may want to consider reaching out to the provider to request integration with QuickBooks Online. Currently, the direct bank feed integration for the Comdata card is unavailable, but exploring this option could help enable more connectivity in the future.
 
For now, you can still manually upload your Comdata card transactions into QuickBooks Online. This option is available for financial institutions that aren't included in QuickBooks' bank connection list. When exporting data from your Comdata account, ensure the transactions are in a CSV file format and adhere to QuickBooks' formatting requirements for successful upload.
