In Kolleno, navigate to the specific Customer Hub > Configuration
Here, you will see all contacts imported from NetSuite for your customers.
On the screenshot:
(1) If you go over the import source (here, "NetSuite"), you will see where the contact comes from such as : "netsuite_person_661_invoice_custbody15_contact@example.com" means that it comes from the Invoice record, NetSuite customer internal ID 661, and field 'custbody15'.
(2) The column "Invoices" shows all the invoices that contact is linked to in Kolleno.
Some contacts may appear as duplicates, but they probably come from different fields.
