An organization can have multiple IATS accounts. Each IATS account has a client code. The client code is the Login ID when creating a new IATS account in The Raiser's Edge. The client code in IATS correlates with the account that is used to process the transactions. If the incorrect client code is entered in the IATS account information in The Raiser's Edge, it will cause the transactions processed to go through another IATS account. To verify or change the IATS account you have set up in The Raiser's Edge, follow the below steps:

1. Go to Configuration > Business Rules > Merchant Accounts
2. Open the IATS account
3. Ensure the correct login ID is selected
