Also I noticed that on the "Success" page the charge amount displayed is the Net Price. I think it should be the Gross Price.

See example:

I needed to add the actual GST/QST tax to this page.
I noticed that if I'm not setting a tax to the Product it won't apply any sales tax to the checkout.
I'm not convinced that the TaxPart should be necessary on a Product to apply any taxes on it on checkout.
Normally, it should pick up taxes from the Custom Tax table based on user location.

I think that normally it is mandatory to display the tax amount charged and also an indication of which tax has been applied.
Gross Price should never be displayed without tax details.

I can tick Use the gross price display, but there is Tax include which make me confusion.

Gross Price is price with tax included as it seems. I don't like the term to be honest.

This is not a bug, it's intended behavior. But I agree that it would be good to configure the totals separately from price display. I've updated the title accordingly.

The settings should have 4 separate options to mix and match as desired, for example:

• ❎ Display Net Prices
• ⬜ Display Gross Prices
• ⬜ Display Net Total
• ❎ Display Gross Total

I noticed that if I'm not setting a tax to the Product it won't apply any sales tax to the checkout.

As mentioned in the other issue, the product must have a TaxPart to use custom tax rates, but you should not fill out the Tax Rate field in it.

I think that normally it is mandatory to display the tax amount charged and also an indication of which tax has been applied. Gross Price should never be displayed without tax details.

This is true for invoices, but not for web checkout screens. Commonly there are no specific information requirements on web store pages.

This is a common industry term. I'm not a fan of it either, but it's best to use the proper lingo. Also each checkbox has the hint below that says if it's tax included or excluded.
