FON is a Nacha Preferred Partner.
FON strengthens front-line control points across vendor onboarding, supplier maintenance, and payments — verifying vendor information, validating bank account ownership, running compliance checks, and reducing exposure to business email compromise (BEC) before payments are made.
VendorInfo is a vendor portal for onboarding: it verifies tax IDs, screens OFAC and validates bank account ownership before a vendor is paid. InvoiceInfo is a supplier portal for after the invoice: suppliers look up invoice status, payment dates and remittance advice themselves instead of emailing AP. Both sit on top of the same ERP and are often used together.
