FAQ

Which rate should I choose?
Use 10% for the standard preset or 8% only when the transaction qualifies for Japan's reduced-rate rules. Confirm the actual treatment separately.
Why can accounting software differ by one yen?
Systems can apply different rounding and aggregation rules. Match the rounding method and invoice policy used by your organization.
