Depending on your scenario, you may not need to create a vendor profile for each vendor.
If: you are using a system layout (ie. EPN STP 820, 4010, etc..), and your vendors do no not have specific requirements - you do not need to create profiles.
To create CTX files without first creating vendor profiles:
1. At the mapping wizard, instead of mapping a profile lookup, simply use 'Name'
2. Remember to map your vendor's routing number and Account numbers.
Note: You can also map additional fields such as ID Number, etc...
However, please note that the ABA number, Account Number and ID Number is shown only once in the payment record (the '6' record), yet you do need to show them on each line item consistently for each vendor.
