Singapore GST rate increase from 7% to 8% in 2023, and 8% to 9% in 2023.

Business Central Sales Order prepayment posting get the GST rate from the GL account and not the sales order line.

All 2022 pre-payment are invoiced at GST rate of 7%.

From 2023 onwards, the pre-payment invoice should be invoiced at 8% GST.

We accept payment for magazine subscription with the prepayment invoice.

We will invoice the subscription as and when the delivery are perform.

With the outstanding prepayment invoice, we can't change the GST rate for the new prepayment invoice.

We were advised to create a new prepayment GL account for GST 8% and an additional Gen. Business Posting Group for the customers. With that a new combination need to be setup in the General Posting setup. This make the account very messy.

It would be good if pre-payment invoice get the GST rate from Sales Order Line and not GL account?
