To import your Services & Products list, go into Settings > Services & Products. The area to import is at the bottom of this page.
Your CSV will need to have the following header fields in order to upload properly:
In the Cost column, make sure to only have a numeric value, as a $ symbol will cause an issue with the import.
Use the Category column to specify if this is a Product or a Service. If this field is left blank it will default as a Product.
The Taxable column is a true or false value. If this field is left blank, then the system will y default assume that this item is a taxable.
To avoid errors when importing your Services & Products, don't use special characters such as colons (:), semi-colons (;), and quotation marks (' or ").
