Import new data
I'm starting from scratch. I have .csv file of customers with numeric ID. I have another .csv file of invoices, each with a customer ID to identify who is being invoiced. (These are exported from another system.)
How do I get them into wave? Import customers doesn't have an ID in the template and Wave Connect import invoices doesn't tell me about how it will link the invoices to customers.
How do I get this data into wave so I can get started?
