Using the correct account number
The remittance info on a bill payment check includes the Account Number for the vendor. This is taken from the Account Number field on the vendor's profile. Review the vendor profile to ensure that the correct account number was used in the vendor set up.
Multiple accounts with the same vendor
If there are multiple accounts with the same vendor, a best practice is to create and use a separate vendor profile for each account. The Vendor name can include the last four (4) digits of the account number for easy matching. Payments are made using the Pay To field on a vendor profile.
