Can I include an optional VAT number input on my B2B checkout page?

Accounting & Taxes

Topic summary

A B2B Shopify store owner wants to add an optional VAT number input field on their checkout page where customers can enter their VAT information without it being mandatory.

A community member recommends the EU VAT Number Field Checkout app available in the Shopify App Store as a solution. They share their positive experience using this plugin for collecting VAT numbers at checkout.

The question remains open regarding whether the recommended app supports making the VAT field optional rather than required.

Hi @FlorianHeesen ,

I saw you’re looking for a plugin to add a VAT number field on the checkout page.
I highly recommend EU VAT Number Field Checkout – it’s a great solution.

This plugin helped me a lot with adding VAT number collection directly at checkout.
Give it a try – it might be exactly what you need too!
