Step 3 – Choose Your Checkout Logic

Before continuing the setup, you must choose how VAT exemption should be processed in your store.

The app supports two mutually exclusive checkout modes:

• Standard Checkout Logic

• Draft Order Logic

Choosing the wrong option will result in:

• VAT not being removed

• Prices not recalculating

• Unexpected checkout behavior

Where to configure this setting

You can select the checkout logic in the app settings:

Shopify admin → Apps → B2B & Wholesale → Tax & prices → Tax Exempt → General Settings

There you will find the setting:

Use draft order logic

• Disabled → Standard Checkout Logic

• Enabled → Draft Order Logic

Changes take effect immediately.

⚠️ VAT-exclusive pricing

If your store sells prices excluding VAT,
Standard Checkout Logic is the only supported option.

Draft Order Logic is not compatible with VAT-exclusive pricing.

Where to configure this setting

Go to:
Apps → B2B & Wholesale → Tax & prices → Tax Exempt → General Settings

Here you can enable or disable:

• Use draft order logic

Changing this setting immediately changes how checkout works. Do not enable draft order logic if the store already uses B2B draft checkout for custom, volume or bulk prices. Those two draft flows are not combined yet.
