Instead of using the Invoice Inbox, you can make a withdrawal entry by posting it as a Manual ACH on the Register Page. 

Please follow the steps to enter a Withdrawal transaction:

1. Navigate to Accounting / Register Page
2. Select the Account where you want to post the entry from the dropdown 

3. Click on the Add Transaction Button and select Withdrawal

4. In the Withdrawal slide-out, enter the Vendor and other details for the ACH transaction, and Save.
