The Map TALK accounts to QuickBooks Accounts setting allows TALK to categorize a transaction using the Merchant Category Code (MCC) sent by the bank. If this setting is turned off, all the transactions will be categorized using the Default Category. This setting is overridden by the Autoselect vendor's last category used setting. To enable this setting, click the switch inside the QBO Integration tab. A list of all TALK categories will be displayed with the option to chose a matching category. For each category that you wish to map, select a QuickBooks Expense Category from its corresponding dropdown box. Any category that is not mapped will use the Default Category. Once all the desired mapping is completed click the Save Button.
