If your online store is based in the Gulf Cooperation Council (GCC) and sells products and/or services to business customers from one of the GCC countries where VAT applies (the United Arab Emirates and Saudi Arabia), it is essential that you include each customer’s TRN (Tax Registration Number) or TIN (Tax Identification Number)on all of their invoices.

PDF Invoice - Order Printer allows you to capture TRN from your UAE and KSA customers and automatically include them on your invoices.

In this article, we will cover how to include the TRN 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 TRN number over here and Save. The respective invoices would have TRN 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 TRN 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 TRN registration number as a customer note

To add the customer's TRN 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 TRN number into the Customer Note field, using a prefix TRN Registration Number or TRN Number: (e.g., TRN Registration Number: 12345).
  4. Click Save to save your changes.

You can add the TRN 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.
