By default, the suppliers imported from your accounting software can be found on your WayPay account at Suppliers >> Manage Suppliers under Attention Needed tab.

Suppliers are in this section because their payment information is not complete. Once the payment method has been provided or updated for the supplier, the supplier record will move to either Corporation or Individuals tab as applicable. 

For suppliers who already have a valid payment method added in their accounting software can be found under Corporation or Individuals tab as applicable.
