Exportify can export a custom Delimited Text, CSV, or Excel file defined by you.
We can export one line per product in each order, for the orders you select in your Shopify Admin page (/admin/orders).
The columns included in the export file are up to you. Generally, these include:
Product name
Product options
SKU
Quantity
Customer address fields
Products purchased
Discounts
Line item properties
Order notes
Cart attributes
UTM tags for campaign tracking
Taxes
Constants (ex: your 3PL account number)
Logical mappings (ex: shipping service name to carrier service code)
etc.
If you need something else, just ask, and we can probably include it in your Exportify setup.
The best way to get started with a custom format is to send us an email with a sample file showing the fields/columns you need in your exports.
