Question
When importing invoices what customer fields need to match previously entered customers to NOT trigger new customers to be added with each import?
I am importing invoice data in a CSV file from a CRM. The files contain the Customers First and Last name. When importing the name populates in the Customer display name. I have update the customer contact details and added a Parent customer. When importing subsequent invoices QuickBooks does not recognise my previously added customer and adds a new one.
