How can I add a customer input field in the billing address section?

Store Design

Topic summary

Goal: add an input under Billing Address to collect a customer’s GST (Goods and Services Tax) number and include it on invoices.

Proposed solution:

  • Use the Sufio invoicing app to validate tax ID numbers and print customer-provided data on invoices via the customer note section.
  • Pair with the Customer Fields app to add a custom field for the GST number and store it as customer metafields (custom data fields that can be searched/pinned).
  • Reference integration guide: sufio.com/apps-integrations/helium-customer-fields/.

Key details:

  • Sufio can pull information from the customer note section into invoices.
  • Customer Fields lets merchants create and persist custom inputs like GST, attached to the customer profile.

Status and outcomes:

  • The requester acknowledged and thanked for the guidance; no confirmation of implementation yet.
  • No disagreements or alternative methods discussed.

Next steps:

  • Install and configure Sufio + Customer Fields following the integration guide.
  • Verify GST field capture and invoice display as intended.

Hello,
There are a few ways you can go about solving this problem, but I’d recommend Sufio in conjunction with Customer Fields.
Sufio validates tax ID numbers and has the ability to put information from the customer note section of a customer’s account onto an invoice. Customer Fields allows you to save the tax ID numbers as searchable/pinnable metafields.
Here’s an article from Sufio about the integration: https://sufio.com/apps-integrations/helium-customer-fields/
I hope this helps :blush:
