To support Indonesian tax, a new field is added to the invoice generated by the service.

From April 1, 2025, Indonesian tax rates will be calculated as follows:

A 12% VAT rate is applied to transactions related to digital goods (on non-luxury goods/services) to all customers (both B2C and B2B) who are based in Indonesia.
The tax base is adjusted to 11/12 of the selling price. This means the 12% rate is calculated on 11/12 of the selling price. This is only for tax purposes.

The Indonesian invoices now show the following:

12% VAT rate
The TAX BASE (11/12) column that shows the adjusted tax base.
The total price is the selling price minus any discounts plus the tax amount.
