Finance: Introducing date-based interest rates

Classification: IMPORTANT

 

We are introducing Date-based interest rates, improving how interest on overdue receivables is calculated when interest rates change over time.

 

Previously, RamBase used a single global interest rate for all calculations. This could lead to incorrect interest amounts when overdue invoices spanned periods where official rates had changed.

 

With this enhancement, interest rates can now be defined with validity periods. The system automatically applies the correct rate for each time segment when calculating interest, ensuring accurate results even when multiple rate changes occur within the same overdue period.

 

Users maintain interest rates manually per date interval, and the system validates that all periods have a valid rate before calculation. Once interest has been calculated for a period, the related rate intervals cannot be changed, ensuring consistency and auditability.

 

This improvement ensures more accurate interest calculations, reduces the risk of disputes, and aligns RamBase with regulatory interest rate changes over time.
