- Then tick the checkbox corresponding to your case: “Product/item price includes tax" or "Product/item price is excluding tax. (B2B mode)" if you are displaying net prices. Checkout will automatically calculate the set tax rate accordingly. It will be displayed in Checkout portal and in your report.

Troubleshooting
Important notice
in Shopify admin, a payment can be flagged with pending status, look for this transaction in the Checkout portal. If it is indicated as "charged" in the Checkout portal, then you can mark the order as "paid" in Shopify admin.
To accept PayPal you must use the PayPal app provided by Shopify. You cannot accept PayPal payments with Checkout as per Shopify rules.
