If you have a number of contacts associated to one customer, you can do a mass import of these customers from a .csv or .xls spreadsheet. 

This article will explain the relationship between customers and contacts: they are two completely different things. It will also provide information on the provided contacts import template.

A customer can have multiple contacts, however, a contact will only ever have one customer.

In fact, in Method, a contact cannot exist without a customer and vice versa. When you create or import a customer, a contact is automatically created for that customer. 

Once the customer exists, you can import multiple contacts for that customer. However, you cannot import contacts if an existing customer does not exist yet.

If you want further information on the contact, please see our article "What is a contact?"

To add multiple contacts, you will need to import into the Contacts table. 

The above template will provide a framework to show how your spreadsheet should be formatted. Here is a list of the column headers. The number in brackets is the maximum length the field can be. Surpassing that length will result in an error during import.

If there are other fields you want in the template, you can add them in. Please view the Contacts table to see which fields are available. If you have custom fields, you will need to add them to Contacts table first.
