If your online store sells to business customers in Canada, New Zealand, Malaysia, or Singapore, you will be required to include your customer’s GST (Goods and Services Tax) number on all the invoices that you create.

PDF Invoice - Order Printer helps you capture GST numbers from your customers and automatically include them on the invoices they receive.

In this article, we will cover how to include the GST registration number using:

  • B2B Customers section(link)
  • Customer notes

B2B Customers section

Here you will find customers, their last order number and CIN Number.

CIN stands for Customer/Company Identification Number.

Enter your Customer's GST number over here and Save. The respective invoices would have GST number of Customers included. Make sure to enable "Show CIN" on Template settings if it doesn't show up.

Customer Notes Page

In addition to capturing customer GST numbers via your store, you can also manually enter them via the Shopify admin.

This might be a useful option if your sales team regularly creates orders on behalf of your customers or if you need to create an order for a new customer manually.

Add the GST registration number as a customer note

To add the customer's GST number as a customer note:

  1. In your Shopify admin, go to the Customers page.
  2. Select a customer, or click Add customer to create a new customer.
  3. Enter the GST number into the Customer Note field, using a prefix GST Registration Number or GST Number: (e.g., GST Registration Number: 12345).
  4. Click Save to save your changes.

You can add the GST number before or after creating the order. PDF Invoice - Order Printer will automatically sync it and update your invoices as soon as you make changes.

Make sure to enable "Customer Note" on Template settings if it's not showing up.
