Why Does an Ecommerce Store Show a Different Total on the Order Confirmation Page?

A final order total can differ from the earlier checkout estimate if tax, shipping, currency conversion, discounts, or payment adjustments are recalculated at submission. The confirmation should reflect the amount actually recorded by the store and payment provider.

What to check

Compare cart, checkout, order record, payment transaction, tax and shipping rules, and currency precision. Check whether a promotion or address update occurred between estimate and order placement.

Recommended next step

Fix the inconsistent calculation or clarify which amounts are estimates. Reconcile store totals with processor records and test changes that affect taxes, shipping, and discounts before release.
