Settings & Documentation


Imported orders (for example, from a CSV file) work the same way as explained below.

You can configure what document (available documents are shown on the screenshot below) you want to create and exactly when (on what trigger). You can also check "Send the document in email to customer" in order to send the generated document to the customer. You can also disable it anytime. The triggers:

Trigger 1 » When order is paid

The document using this trigger will be created, IF a paid order is created  (or imported) OR an unpaid order is set to paid 

Trigger 2 » When any order is created 

The document using this trigger will be created, IF any type of order is created (or imported)

Trigger 3 » When unpaid order is created

The document using this trigger will be created, IF an unpaid order is created (or imported)

Trigger 4 » When order is fulfilled

The document using this trigger will be created, IF a fulfilled order is created  (or imported) OR an unfulfilled order is set to fulfilled 

Trigger 5 » Never 

The document using this trigger will never be created


Template to use

When creating the invoice, we use this template. You can create and edit your templates in your FastBill account.

If you don’t see your latest templates, click Refresh list now » And we show your latest template list


Any text entered here will appear on the document for each item. If left blank, no unit name will be shown

Example – If you enter “pc” here, you will see this unit name in every document item


This text will be shown as a description of the invoice in FastBill. You can use this merge tag: {{order_number}}

Example: if you write “This order is from XY Webshop, order number: {{order_number}}” this will be the description of your document, shown on your FastBill dashboard. 

Order cancelation

You have the flexibility to decide the outcome when you cancel an order in Shopify.


  • No canceling or deletion
  • Cancel the document in FastBill

Content parameters not listed above – that you can’t configure on your dashboard – work like this:

  • VAT » We use Shopify order data and your Shopify VAT settings
  • Currency » We use Shopify order data
  • OSS » Automatically
