Product Schema

This page documents how pricing and tax fields are stored on the Ecommerce product and product_variant schemas, and how the platform resolves the final price.

Tax handling on products

Each product and variant records how its price was entered so the platform can always resolve the correct net price and tax. The key field is is_tax_included.

is_tax_included is an entry convention, not a display setting. It tells the platform whether the figure entered against the product already includes tax.

Fields

How the price is resolved

is_tax_included = true (entered figure is gross):

• net = price / (1 + tax_amount / 100)
• tax = net × (tax_amount / 100)
• total = net + tax

is_tax_included = false (entered figure is net):

• net = price
• tax = net × (tax_amount / 100)
• total = net + tax

When is_fixed_tax_amount is true, tax_amount is used directly instead of a percentage.

Worked example

Both rows resolve to the same net, tax, and total.

Why the flag is per product

Pricing data often arrives in different conventions across supplier feeds and imports. Setting the convention per product lets merchants enter prices as the data arrives, while the platform normalises everything to consistent net, tax, and total values. For consistent storefront display, enter prices on a consistent basis across the catalogue.
