The total price in Magento and eBay/Amazon/Walmart Orders may differ if you set additional Magento tax settings. Here are the most common cases:
- If you choose the "Magento" option in Account Settings > Order Tax Settings > Tax Source, a Magento order will be created based on the Magento tax settings. In case Magento and Channel tax settings are different, the order total price also differs.
- If you choose the "eBay(Amazon, Walmart) & Magento" option in Account Settings > Order Tax Settings > Tax Source, and there are no Channel tax settings, a Magento order will be created based on the Magento tax settings. The order totals will be different.
- If you set one of the Magento Tax settings, e.g. Customer Tax Class, Product Tax Class, or Tax Zones, the total price in Magento and Channel Orders may differ. For example, you set a 10% tax rate for the USA, CA region. If buyers are from CA, this 10% will be added to the price in the Magento order.
