How FlowPO Applies Tax to Purchase Order Line Items

Overview:
When you create or regenerate a purchase order, FlowPO picks a tax code for each line item automatically. It checks whether the product is marked Taxable in Shopify and whether the product has its own tax code under the vendor.

Description:

Where product tax rates are set

Go to Vendors > Edit vendor > Manage products. Products that are taxable in Shopify have a Tax rate dropdown where you choose a rate. Products that are not taxable in Shopify show Non-Taxable and have no dropdown, so you can’t give them a tax rate.

How FlowPO picks the tax code

Rule 1: Product-level tax code
If the product is taxable in Shopify and you’ve set a tax rate for it under the vendor, FlowPO uses that rate.

Rule 2: Default purchase tax
If the product is taxable in Shopify but has no tax rate set under the vendor, FlowPO uses the Default purchase tax from Preferences > Tax rates.

Rule 3: Zero-rated for non-taxable products
If the product is not taxable in Shopify, FlowPO always uses the Zero-rated tax set in Preferences.
