What this result excludes
Tax collected from a buyer is not automatically revenue or cost. Chargebacks, refunds, currency conversion, subscriptions, marketplace-facilitator treatment, and consumer-law obligations differ by path. Put a defensible expected amount in the reserve or other-cost field and preserve the source and review date outside this browser-only tool.
